Thrust bearing installation

   Plane thrust bearings in the assembly to bear the axial load, its wide range of applications. Plane thrust bearings in the assembly to bear the axial load, its wide range of applications. Although the thrust bearing installation operation is relatively simple, although the thrust bearing installation operation is relatively simple, but the actual maintenance is often wrong, that is, the bearing ring and loose ring installation location is not correct, that is, the bearing ring and loose ring installation Inaccurate location, resulting in loss of bearing, journal quickly worn. Tight ring inner ring and journal for the transition fit, to role, the journal quickly wear. Tight ring The inner ring and the journal for the transition with the shaft rotation when driven by the tight ring, and friction with the stationary end face, when the shaft rotates to drive the tight ring, and friction with the stationary end face, when subjected to axial force Frictional torque is greater than the inner diameter with the resistance torque, to the force, there will be friction torque is greater than the inner diameter with the resistance torque, resulting in forced rotation of tight ring and shaft mating surface, aggravating journal wear.
Therefore, the thrust bearing installation should pay attention to the following points.
(1) distinguish between the tight ring and loose ring bearing (according to the size of the bearing diameter to determine the diameter of the bearing ring clear and loose ring O.1 ~ O.5mm).
(2) to distinguish the stationary parts of the organization (that is, parts that do not move, mainly refer to the stationary parts of the assembly division agencies).
(3) In any case, the loose ring of the bearing should always rest on the end face of the stationary part. No matter what the situation.
