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 The raceway ring matched with the shaft is called the shaft ring, and the raceway ring matched with the shell is called the seat ring The two-way bearing fits the middle ring with the shaft One way bearing can bear one-way axial load, and two-way bearing can bear two-way axial load The bearing with spherical mounting surface of race has centering performance, which can reduce the influence of installation error This kind of bearing is mainly used in automobile steering mechanism and machine tool spindle Thrust roller bearings are divided into thrust cylindrical roller bearings, thrust self - aligning roller bearings, thrust tapered roller bearings and thrust needle roller bearings Thrust cylindrical roller bearings are mainly used in oil drilling rigs, iron and steel machinery Thrust self-aligning roller bearings are mainly used in hydraulic generators, vertical motors, marine propeller shafts, tower cranes, extruders, etc Thrust tapered roller bearing this kind of bearing is mainly used for one-way: crane hook, oil drilling rig swivel Bidirectional: roll neck of rolling mill Plane thrust bearing mainly bears axial load in the assembly, which is widely used. Although the installation operation of thrust bearing is relatively simple, errors often occur in actual maintenance, that is, the installation position of tight ring and loose ring of bearing is incorrect, resulting in the loss of function of bearing and rapid wear of journal. The tightening ring is installed on the end face of the stationary part, that is, it is wrongly assembled. The inner ring of the tightening ring is in transition fit with the shaft journal. When the shaft rotates, it drives the tightening ring and rubs with the end face of the stationary part. When subjected to the axial force (FX), the friction torque will be greater than the matching resistance torque of the inner diameter, resulting in the forced rotation of the tightening ring and the matching surface of the shaft and aggravating the wear of the shaft journal.
