Working principle:
Thrust ball bearing is a kind of separation bearing. The shaft ring and seat ring can be separated from the cage and steel ball components. The shaft ring is matched with the shaft ring, the seat ring is matched with the bearing seat hole ring, and there is a gap between the shaft; Thrust ball bearings can only bear axial load, one-way thrust ball bearings can only bear axial load in one direction, two-way thrust ball bearings can bear axial load in two directions; Thrust ball bearings can not limit the radial displacement of the shaft, the limit speed is very low, one-way thrust ball bearings can limit the axial displacement of the shaft and the shell in one direction, two-way bearings can limit the axial displacement of the two directions. Thrust roller bearings are used to bear combined axial and radial loads mainly in axial direction, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction coefficient, higher speed and self-aligning performance. The rod of type 29000 bearing is asymmetric spherical roller, which can reduce the relative sliding of roller and raceway at work. Moreover, the roller is long and large in diameter, the number of rollers is large, and the load capacity is high. Oil lubrication is usually used, and grease lubrication can be used in some cases of low speed. In the design selection, should be preferred; 80000 type thrust cylindrical roller bearing, 90000 type thrust tapered roller bearing and AXK type thrust needle roller bearing can withstand unidirectional axial load, which is much larger than the axial load capacity of thrust ball bearing, and large rigidity, occupy small axial space. Thrust cylindrical roller bearing and thrust needle roller bearing are suitable for the occasion of low speed, the speed of thrust tapered roller bearing is slightly higher than that of thrust cylindrical roller bearing.Classification application:
Thrust bearings are divided into thrust ball bearings and thrust roller bearings. Thrust ball bearings are divided into thrust ball bearings and thrust angular contact ball bearings. A raceway ring with a raceway gasket and a ball and a cage assembly is called a raceway ring with a shaft, and a raceway ring with a housing is called a seat ring. Two-way bearings match the center ring with the shaft. Unidirectional bearing can bear unidirectional axial load, and bidirectional bearing can bear bidirectional axial load. The bearing with spherical mounting surface of the seat ring has self-aligning performance, which can reduce the influence of installation error. This kind of bearing is mainly used in automobile steering mechanism, machine tool spindle. Thrust roller bearings are divided into thrust cylindrical roller bearings, thrust self-alting roller bearings, thrust tapered roller bearings, thrust needle roller bearings. Thrust cylindrical roller bearings are mainly used in oil drilling RIGS, iron and steel machinery. This kind of thrust self-aligning roller bearing is mainly used in hydraulic generator, vertical motor, ship propeller shaft, tower crane, extruder and so on. Thrust tapered roller bearing this kind of bearing main uses: one-way: crane hook, oil drilling ring. Two-way: roll neck of rolling mill. Planar thrust bearing is mainly subjected to axial load in assembly and is widely used. Although the installation and operation of thrust bearings are relatively simple, errors often occur in actual maintenance, that is, the installation position of the tight ring and loose ring of the bearings is not correct, which results in the loss of the bearing and the journal is quickly worn out. The tight ring is installed on the end face of the stationary part, that is, wrong assembly. The inner ring of the tight ring is a transition fit with the shaft journal. When the shaft rotates, the tight ring is driven and friction occurs with the end face of the stationary part. When the axial force (Fx) is applied, the friction torque is greater than the resistance moment of the inner diameter fit, resulting in forced rotation of the tight ring and the shaft mating surface, which intensifies the wear of the shaft journal.Thrust ball bearing classification:
1. Thrust ball bearing is a kind of separation bearing. The shaft ring and seat ring can be separated from the cage and steel ball components. The shaft ring is matched with the shaft ring, the seat ring is matched with the bearing seat hole ring, and there is a gap between the shaft; Thrust ball bearings can only withstand axial loads, 2. Unidirectional thrust ball bearings can only bear axial load in one direction. 3. Bidirectional thrust ball bearing, which can bear axial load in two directions; 4. Thrust ball bearings can not limit the radial displacement of the shaft, and the limit speed is very low. 5. Unidirectional thrust ball bearing, which can limit the axial displacement of shaft and shell in one direction, Two-way bearings can limit the axial displacement in both directions. 7. Thrust roller bearings are used for bearing axial and radial combined loads mainly, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction coefficient, higher speed and self-aligning performance. The roller of type 29000 bearing is asymmetric spherical roller, which can reduce the relative sliding of roller and raceway at work. Besides, the roller is long and large in diameter, the number of rollers is large, and the load capacity is high. Oil lubrication is usually used, and grease lubrication can be used in some cases of low speed.
