Agricultural machinery bearing is a variety of mechanical rotating shaft or movable parts of the supporting parts, in the agricultural automobile, tractor, thresher and other agricultural machinery is widely used, its quality directly affects the precision, performance, life and reliability of agricultural machinery. There are many types of agricultural machinery bearings, commonly used agricultural machinery ball bearings, angular contact ball bearings, outer spherical bearings, needle roller bearings, tapered roller bearings, etc., when choosing, mainly consider the type of agricultural machinery, mechanical accuracy requirements, the required load size and other aspects. Let’s understand the knowledge of agricultural machinery bearing.
1、What is agricultural machinery bearing?
Agricultural machinery bearing is one of the commonly used parts of agricultural machinery, widely used in agricultural cars, tractors, diesel engines, motors, grass arm machine, baling machine, harvester, thresher and other agricultural machinery, its precision, performance, life and reliability of the host precision, performance, life and reliability plays a decisive role.
Agricultural machinery bearing can continue to withstand continuous vibration and high impact load, meet the reliable operation in various weather conditions, the structure design is very simple, can ensure the efficient use of the machine.
2、what are the common models of agricultural machinery bearings?
Agricultural machinery equipment also has many types, the use of occasions and purposes are different, so the use of bearings will be different, agricultural machinery commonly used bearings are: agricultural machinery ball bearings (round hole, square hole or hexagonal hole, lock ring, relubricating oil hole or nozzle), angular contact ball bearings, spherical bearings, needle roller bearings, tapered roller bearings, etc., the main models are:
1).grinder 6205RS, 6206RS, 6207RS, 6208RS, 6309RS.
2). Rice grinding machine: 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).seeder: 6806-2RS, 6807-2RS.
6). Corn planter: 6004RS, 6204RS.
7).grain depot conveyor: 6203RS, 6204RS, 6205RS, 6207RS, 6208RS, 6307RS, 6308RS.
8). Turbine Reducer: 7207 (30207), 7208 (30208)
9). Well gear transmission: 42211, 42215, 42304, 42306, 42310, 42312.
3、how to select agricultural machinery bearings
Agricultural machinery bearings must be able to operate in extremely challenging conditions and adapt to dry and abrasive environment to wet, corrosive and highly polluted environment. Therefore, attention should be paid to choosing the appropriate model when selecting. The selection of agricultural machinery bearings should mainly consider two aspects:
1). The type of agricultural machinery bearings: mainly consider the load size, direction, impact, speed level, aligning requirements, allowed space and other factors to choose agricultural machinery bearings.
2). Precision of agricultural machinery bearing: should consider the type of agricultural machinery, mechanical precision requirements, precision generally does not need to be as high as precision machinery, which is determined by the nature of agricultural machinery.
