Definition of agricultural machinery bearings

Agricultural machinery bearings are one of the commonly used accessories for agricultural machinery. They are widely used in agricultural vehicles, tractors, diesel engines, electric motors, hay rake, balers, harvesters, threshers and other agricultural machinery. Its accuracy, performance, life and reliability are crucial to The accuracy, performance, life and reliability of the host play a decisive role.

Agricultural machinery bearings can continue to withstand continuous vibration and high impact loads, and can operate reliably under various weather conditions. The structural design is very simple, ensuring efficient utilization of the machine.

Bearing structure of agricultural machinery bearings

Agricultural machinery bearings have a simple structure and are easy to achieve higher manufacturing precision compared with other types. Therefore, they are conducive to mass production and have low manufacturing costs. In addition to standard types, agricultural machinery bearings also have various modified structures, such as: agricultural machinery bearings with sealing covers, agricultural machinery bearings with silicone sealing rings, agricultural machinery bearings with stop grooves, and agricultural machinery bearings with stop grooves Bearing capacity of steel ball slots, double row agricultural machinery bearings.

Principles of agricultural machinery bearings

Agricultural machinery bearings are a common type of rolling bearings. The basic agricultural machinery bearing consists of an outer side, an inner hole, a set of bearing steel balls and a set of ball bearings. There are two types of agricultural machinery bearings: column and double row. There are two types of deep groove ball structures: sealed and open.

 Agricultural machinery bearings mainly bear axial load, but can also bear axial load and radial load at the same time. When it bears only axial load, the interfacial tension is zero. When the axial backlash of agricultural machinery bearings is large, they have the characteristics of angular contact bearings and can bear large radial loads. The friction resistance of agricultural machinery bearings is not large, and the limit speed ratio is also very high.

How to choose agricultural machinery bearings

Agricultural machinery bearings must be able to operate in extremely challenging conditions, adapting to environments ranging from dry and abrasive to humid, corrosive, and highly polluted environments. Therefore, when selecting, pay attention to selecting the appropriate model. Selection of agricultural machinery bearings There are two main aspects to consider:

1. Types of agricultural machinery bearings

Mainly consider factors such as the load size and direction of the bearings required by agricultural machinery, whether there is impact, speed, alignment requirements, allowed space and other factors.

2. Accuracy of agricultural machinery bearings

The type of agricultural machinery, mechanical accuracy requirements, etc. should be considered. Accuracy generally does not need to be as high as precision machinery. This is determined by the operating nature of agricultural machinery.
