Selection and common models of agricultural machinery bearings

1. What is agricultural machinery bearing?

 Agricultural machinery bearing is one of the commonly used accessories of agricultural machinery. It is widely used in agricultural vehicles, tractors, diesel engines, electric motors, hay rakes, balers, harvesters, threshers and other agricultural machinery. Performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the host.

Agricultural machinery bearings can sustain continuous vibration and high impact loads, and can operate reliably under various weather conditions. The structure design is very simple, which can ensure the efficient utilization of the machine.

2. What are the commonly used models of agricultural machinery bearings?

There are also many types of equipment in agricultural machinery. The occasions and uses are different, so the bearings used are also different. The commonly used bearings in agricultural machinery are: agricultural machinery ball bearings (round hole, square hole or hexagonal hole, lock ring, relubrication) Oil holes or oil nozzles), angular contact ball bearings, outer spherical bearings, needle roller bearings, tapered roller bearings, etc. The models are mainly:

1. Crusher

6205RS, 6206RS, 6207RS, 6208RS, 6309RS.

2. Rice mill

1206, 1207, 1308, 1310, 1312, 1213, 1217.

3. Corn thresher

6201RS, 6203RS, 1203, 1204, 1205, 6205RS, 6206RS, 6305RS, 6307RS, 6308RS, UCP205, UCP206, UCP207.

4. Wheat seeder

Hexagon 6204RS, square eye 6205RS.

5. Planter

6806-2RS, 6807-2RS.

6. Corn planter

6004RS, 6204RS.

7. Grain depot conveyor

6203RS, 6204RS, 6205RS, 6207RS, 6208RS, 6307RS, 6308RS.

8. Turbo reducer

7207 (30207), 7208 (30208).

9. Gearbox of well rig

42211, 42215, 42304, 42306, 42310, 42312.

3. How to choose agricultural machinery bearings

Agricultural machinery bearings must be able to operate under extremely challenging conditions, from dry and abrasive environments to wet, corrosive, and highly polluted environments, so pay attention to choosing the appropriate model when choosing, and the selection of agricultural machinery bearings Two main aspects are considered:

1. Types of agricultural machinery bearings

Mainly consider the load size, direction, whether there is impact, speed level, alignment requirements, allowable space and other factors of the bearing that agricultural machinery needs to select.

2. The accuracy of agricultural machinery bearings

The type of agricultural machinery, the requirements for mechanical accuracy, etc. should be considered. Generally, the accuracy does not need to be as high as that of precision machinery, which is determined by the nature of the operation of agricultural machinery.

Anti-corrosion treatment method of agricultural machinery bearings

1) Surface finish: The appropriate method must be selected according to the surface characteristics of the anti-corrosion body and the standards at that time. Usually there are organic solvent washing, organic chemical solution and mechanical cleaning equipment.

2) After drying and cleaning the surface, consider drying the compressed air, or drying it from the air at 120℃*170℃, or wiping it with a clean cloth.

Analysis of Damage Causes of Agricultural Machinery Bearings

If the agricultural machinery bearings roll correctly without the correct selection, they can be used for a long time before the life of the agricultural machinery bearings. In this case, the damage is separate. On the other hand, accidental and early corruption occurs, which is not conducive to the initial corruption of the application. Due to this initial damage and defects in lubrication applications, there is also the problem of dirt penetration, large total deviation of agricultural machinery bearings, large shaft deflection, and insufficient scientific research work on agricultural machinery shaft bearings.
