Verobnik of motoblocks NMB-1 Ugra - VAT Kaluzky dvigun, (CADVI) m. Kaluga, vul. Moskovska, 247

Today, VAT "Kaluzky Dvigun" is a highly specialized enterprise, highly mechanized and automated, equipped with unique technological equipment. The 37-year proof of production guarantees the vibrancy and high reliability of the viruses. The development of production for enterprise is taking place in many countries directly. We are focused on the production of complex and scientific products.

The history of the enterprise began in 1966, when a new enterprise was created on the basis of one of the workshops of the Kaluzky Turbine Plant and the Kaluzky branch of the Scientific Research Automotive and Automotive Institute. additional motor plant.

Official website of the generator for the NMB-1 Ugra walk-behind tractor http://www.kadvi.ru

Motoblock NMB-1 Ugra a strong, reliable, safe machine. The best confirmation of quality is the courtyard guarantee.
The complex with hanging equipment has a varied range of jobs: soil preparation, mowing, spraying, watering, digging and planting potatoes, transporting fertilizers, collecting snow. Two factors make it difficult to make the walk-behind tractor universal and allow you to easily connect a wide range of additional attachments, for example, such as a water pump.

The gearbox and gear drive gear are assembled from metal-ceramic disks, which significantly increases the reliability of the robot. These are the design elements of the attached professional technology. The presence of drive V-belts has completely eliminated the problems associated with them: slipping, shearing, snagging.
The gearbox has 3 speeds forward and 1 speed reverse, which optimizes the work with attached and suspended implements.

Optimization of Swiss regimes

The steering column is easily adjustable in vertical and horizontal directions, and there is no vibration protection. The rotation of the kerma in a horizontal plane allows the soil to be “trampled” during cultivation. “Ugra” is a single Russian walk-behind tractor that complies with European safety standards. The control system (black handle of the engine (left handle)) and the important blocking of the reverse clutch (right handle) allows you to move the unit safely in an emergency situation.

Two tension-selecting shafts on the gearbox allow you to drive stationary work on a wide range of mounted implements: a circular saw, a feed mill, a water pump, an earth drill, and others.

With minimal disassembly, the walk-behind tractor can easily fit into the trunk of any passenger car, which makes transportation much easier.

Technical characteristics of the NMB-1 Ugra walk-behind tractor

Evidence from city workers indicates that ground clearance of up to 170 mm and a low center of gravity provide high durability and prevent damage to the heights during operation. An ergonomic control system and variable adjustment make the operator’s work comfortable, minimizing unnecessary spills on the operator, ground and growth.

Varieties of walk-behind tractors NMB-1 Ugra

We direct the window from the assistant of the koristuvach, where modifications are indicated according to the installed engine.

The most popular walk-behind tractors with Subaru and Lifan engines.

The importance of modifications of Ugra NMB-1N and NBM-1M- Caliper (cut gearbox) - Transmission number - 12.73 - for NMB-1(M). The transmission number is 25.46 for NMB-1(N).

It is not possible to begin repairing the gearbox on a walk-behind tractor on your own, since the robot unit and device of the new operator is again a mystery. If the box is broken into a folding unit, then proceed to do-it-yourself repairs immediately after any damage is detected. It will be better if the repair of the gearbox is carried out by professionals.

It was discovered that oil was leaking from the gearbox, and therefore the seals of the bearing assemblies were installed incorrectly or worn. The stench may be badly lingering on the lids. Under them, the gaskets may become damaged. If you find that the breather valve (breather) is clogged, it is necessary to clean it and bring the oil level to normal. Oil leaks can be corrected by replacing or correctly installing oil seals or gaskets. Solve the problem by tightening the bolts and covers.

See the damage at the checkpoint and how to fix it

If the automatic transmission mechanism ceases to function normally, the following types of problems may occur:

1. Damage to the kinematic linkage in the middle of the gearbox.
2. Mimovilny increase in transmission or the frequency of their fixation.
3. Oil leakage on the shaft.
4. Damage to the function of the wire dispensing mechanism.
5. The frequency of transmission mixing.
6. Gearbox jammed.

If the kinematic connection in the middle of the gearbox is damaged or the wheel in the block is broken, it is necessary to disassemble the gearbox to replace the problematic wheel. The cause of oil leakage on the alternating shaft may be due to excess oil in the gearbox, so it is necessary to check the oil level. If the welding part of the gear is cut, having removed the gearbox, change the block shaft. If there is excess oil, then check the level of wear of the working edge of the cuff on the alternating shaft, disassemble the gearbox and replace the part.

The reason for the lack of fixation of gears or their temporary vibration is the disruption of regulation of the gear shifting mechanism. To make a difficult repair, loosen the screws securing the plate to the switching mechanism.

Then turn on the first gear and tighten the screws securing the board. For example, having built a minitractor with your own hands, you must be careful to ensure that the drive is adjusted correctly, by changing the tension of the control cable for the connectors. To correct the breakdown of any element of the drive, disconnect the center of the gearbox, then disassemble the gearbox, replacing the damaged parts.

If a broken spring or worn-out retainer of the transmission mechanism has been detected, then replace the sealed parts and adjust the transmission adjustment. If you do this every day, you may find that the cracker has been cut or the handles have been cut with a threaded piece. After disassembling the gearbox, it will be necessary to replace defective parts. If the gears shift, remove the gearbox and replace the worn gear shift fork. If the reason for the gearbox jamming is due to the cutting of the lance, then remove it and replace the lance.

Since the gearbox operation is accompanied by noise in the gearbox, the reason for this may be a lack of oil in the gearbox unit or the lack of oil quality to the necessary parameters. It is necessary to choose oils of the same brand to ensure cleanliness. If there are any problems, you will need to replace the oil or add it to the gearbox.

The noise at the transmission units of the walk-behind tractor may be caused by weakly tightened fastenings, so you need to look at the fastening parts that have tightened them like a trace.

The reason for some noise is the wear of gears and bearings. This can cause serious damage to the walk-behind tractor gearbox. It is not important to get rid of them, as long as you perform a proper inspection and repair of the walk-behind tractor. It is necessary to urgently replace worn-out assemblies and parts.

If the transmission components of the walk-behind tractor become heated, the following are the main causes of this malfunction:

1. There is a small amount of transmission fluid in the crankcases.
2. Worn bearings.
3. Inconsistency of condition with any necessary parameters.

There can be two reasons for correcting deficiencies:

• bearings replaced;
• added or replaced by olia.

In order for the gearbox or automatic gearbox to serve longer, it is necessary to periodically check the level of oil in them, in order to avoid a sudden change in fluidity.

Signs of failure associated with difficulties in fluid movement, momentary slippage, disruption of the process of turning on the unit are due to the following reasons:

1. Worn parts.
2. Washing slot rolls.
3. Incorrect regulation of the circuit.

Rolling (wear) of the ends of the gears that are turned on causes two problems, leading to self-locking or incorrect inclusion of the fluids.

Visnovok

If a factory or self-made gearbox has any damage, it is necessary to disassemble it, as well as straighten the gear teeth using a grinding method. If there is a lot of wear and tear, it is necessary to install new parts. To adjust the axial position of the shafts, it is necessary to install additional locking rings. In severe cases, replace worn bearings and rings.

Adjustment of the gearbox for the walk-behind tractor should be carried out promptly, otherwise it will stop coming out and difficulties may arise when switching gears. When used with a walk-behind tractor, folding machines often get stuck for beginners, because due to inadequacy they can lower the clutch value in advance when changing the transmission.

The Ugra walk-behind tractor is a richly functional machine, intended for the construction of agricultural work in rural and farming states, in garden plots, gardens and cities for individual farming. The unit was dismantled and released by the Russian company VAT “Kaluzky Dvigun” (VAT “CADVI”).

Attachment to walk-behind tractor

The walk-behind tractor consists of the following main components: engine 1, transmission 2, chassis 3 and controls 4.

Engine and safety system

The drive of the walk-behind tractor is a classic internal combustion engine with all the systems necessary for its robot. Light and medium-class cars use four-stroke gasoline engines. Walk-behind tractors of an important class are often equipped with diesel engines.

Most small-scale walk-behind tractors are powered by four-stroke gasoline engines with air cooling. These engines power the following robot safety systems:

• The combustion fuel supply system is designed for the preparation of a combustion chamber, which consists of a combustion tank with a tap, a combustion hose, a carburetor, and a combustion filter.
• A lubricating system that ensures the lubricating of parts that rub.
• The starting mechanism (starter) is used for rotating the crankshaft. Many engines are equipped with an easy-start mechanism, which reduces the force of starting the device on the spacer shaft, which opens the exhaust valve during the compression stroke and thereby changes the compression in the cylinder when the cylinder is untwisted. Inval. Heavy walk-behind tractors are sometimes equipped with electric starters that operate on batteries. Some models have electric and manual start. The remaining vikorist is considered as a reserve.
• A cooling system that removes heat from the engine cylinder block by a flow of air that is pumped by the flywheel impeller when the crankshaft is wrapped.
• A firing system that ensures uninterrupted sparking on the firing candle. The flywheel, which wraps around a magnetic sheath, induces an e.m.f. into the magneto, which is transformed by an additional electronic circuit into electrical signals that are supplied to the spark plug. As a result, a spark jumps between the remaining contacts, which takes up heat and heat.

• A gas distribution system, which ensures the proper flow of a burning mixture into the engine cylinder and the release of processed gases. The warehouse of the gas distribution system includes a muffler for direct release of processed gases and noise reduction.

Transmission

The transmission serves to transmit the torque from the engine to the wheels and change the speed and directly to the wheel of the walk-behind tractor. It consists of several units, sequentially connected one after another: gearbox, differential (in some models), clutch, gearbox. These elements can be structurally connected to look like adjacent units or combined in one housing. The gearbox is used to alternate between different types of fluids (up to 6 front and 2 rear), and at the same time a gearbox.

Depending on their type, transmission units (reducers and gearboxes) can be gear, belt, lance or be a variety of these and others.

Classic transmission gear, Which consists only of cylindrical and final gears, is installed mainly on important walk-behind tractors and many models of medium-sized machines. As a rule, there is a reverse of the same number of lower steps.

The picture below shows the transmission gear of the Ugra walk-behind tractor NMB-1, which consists of cylindrical and final gears. The engine is tightly attached to the box, as it is tightly connected to the gearbox. The design of the NMB-1 walk-behind tractor does not have lance and belt drives, which, in the opinion of the experts, does not have an unreliable transmission link due to the slippage of the belt, which can cause damage and slippage.

The turning torque from the crankshaft is transmitted to the drive shaft 16 (Gearbox Diagram) of the gearbox and is taken from the final gear of the driven shaft 15 by the vertical shaft 6 of the cut-off gearbox (Scheme of the cut-off gearbox), which transmits the wrap to the hexagonal shaft 8. To avoid damage to the correct operation of the transmission , it is not recommended to disassemble the walk-behind tractor transmission, as this may damage the adjustment gears.

The gearbox, by its design, is a mechanical two-way transmission with three forward gears and a first reverse gear. The transmission has two shafts to select pressure (A) and (B).

Gear-worm transmissions , Which consists of two gearboxes - the upper gear and the lower worm - are used on light walk-behind tractors. The motor shaft is rotated vertically. Some machines with a gear-worm transmission are equipped with a central automatic clutch. A similar device to the walk-behind tractor will ensure increased compactness of the unit.

Belt-gear, belt-lance and belt-gear-lance transmissions є make it wider on light and medium walk-behind tractors. The engine wraps around the shaft of a six-wheel or lance-type gearbox behind an additional belt drive, which is simultaneously coupled. Gear-lance transmissions are often implemented in one crankcase.

In the case of a belt drive, changing the speed of the walk-behind tractor and selecting the tension, the pulleys can cause additional wear. The operation of such a transmission requires the simplest operation of a gear transmission, disassembling and folding of a walk-behind tractor.

The coupling function is implemented through an additional tension roller and control mechanism, which consists of a traction and a system of important elements that allow you to change the position of the roller, which tightens or loosens the belt and, obviously, turns on or turns off the transmission of torque from the motor to the gearbox. The mixing of fluids occurs with the help of yard pulleys. When moving the belt from one wheel to another, maintain a different fluidity to the handle of the walk-behind tractor.

As a rule, the transmissions of walk-behind tractors falter stop exerting yourself, to ensure the transmission of the moment that wraps up to the working parts of the machine. According to their type and place of rotation in the transmission, the tension selection shafts can be independent, which are expanded to the point of consolidation and wrapped independently of its state (either switched on or included), or stale, which are rotated for recording, and synchronous singing transmission. In one walk-behind tractor there can be a number of shafts to select the tightness - different in the type and fluidity of the wrap.

Zcheplennya

The gearbox, which is part of the transmission, has several functions. Transmission of torque from the engine crankshaft to the gearbox (gearbox) shaft, disconnection of the gearbox and engine during the alternation of gears, ensuring smooth rotation of the walk-behind tractor from the place of the other gear without connecting the engine.

Structurally, the structure can be constructed in different ways. In the case of a V-type transmission (a marvelous thing), the tension or loosening of the belt, which, in addition to the coupling, must be carried out before the transmission or transmission of torque from the motor to the gearbox. It looks like a single-disc or multi-disc friction dry or wet (oil) seal, which is the most reliable and is found in most models of walk-behind tractors. Some machines have a very rare final clutch that is stuck.

On the already reviewed walk-behind tractor "Ugra" LLC "Kadvi" a coupling is installed, which, due to its design, is the most traditional - a frictional multi-disk with a pressure spring, which operates in an oil bath. The attachment of a walk-behind tractor with similar seals can transfer the presence of the crankcase to the seal where the transmission oil is poured.

The coupling consists of a conductive coupling 2 (motoblock coupling diagram), a driven coupling 3, a disk spring 4, a conductor 5 and drive discs 6, a fixed ring 7. It works in the next order. When the container is released, the spring compresses the conductive disks, collected in a bag through. By rubbing the shaft between the discs, the torque that turns from the engine to the gearbox is transmitted. When the importance of coupling is selected, the power supply for the additional cable is transferred to the valve of coupling 4 (Importance of coupling). In this case, the coupling fork through 2 driven couplings and primary bearings compresses the spring, disconnecting the driving disks and applying the transmission to the torque that wraps.

Differential

To enhance maneuverability and create smooth turns, the design of several walk-behind tractors (the most important ones) is equipped with a differential. The purpose of the rest is to ensure the wrapping of the left and right wheels with different fluidity. Differentials can be equipped with or without a wheel locking function. The differential can be replaced by mechanisms that allow one wheel to roll during a crash.

Khodova partina

The running part of the walk-behind tractor is a frame on which the main joints and wheels are fixed. However, the frame is different, and its role depends on the transmission to which the engine and wheels are attached.

On most walk-behind tractors, the distance between the wheels can be changed, which ensures the ability to install wheels of different widths. There are two main types of wheels - initially pneumatic and heavy metal with wide lugs. Important components can be welded to the wheels or secured to them using additional bolts. The structure of the metal wheels is rich in the fastening of various components. This allows, if necessary, to increase the power of the walk-behind tractor to a value that ensures the necessary sealing of the wheels from the soil.

Metal wheels can have a solid rim or two or three thin hoops, tied together with grommets. The first ones are the small part where soil accumulates between the wheel seals, which prevents the tires from sealing the wheels from the soil.
