Thrust ball bearings use: only for one side of the axial load, low speed parts, only for one side of the axial load, low speed parts, such as crane hooks, instantaneous water pump, immediately centrifugal Machine, jack, such as crane hook, immediately pump, immediately centrifuge, jack, low-speed reducer. Bearing shaft ring, seat ring and the rolling body is separated, such as speed reducer. Bearing shaft ring, seat ring and the rolling body is separate, can be installed separately.
Plane thrust bearing in the assembly of the main axial load, its wide range of applications. Plane thrust bearing in the assembly of the main axial load, its wide range of applications. Although the thrust bearing installation and operation is relatively simple, although the thrust bearing installation and operation is relatively simple, but the actual maintenance is still often wrong, that is, bearing tight ring and loose ring installation location is not correct, that is bearing the tight ring and loose ring installation Position is not correct, the result of the loss of the bearing, the journal is quickly worn. Tight ring with the journal and the inner ring for the transition to the role, the journal is quickly worn. When the shaft is rotated, it will drive the tight ring and friction with the end surface of the stationary part. When the axial force (Fx (Fx)) is applied to the end of the stationary part, (Fx), the frictional torque will be greater than the inner diameter of the resistance torque, leading to (Fx) caused by the tight ring with the axis of the surface forcibly rotate, increasing journal wear. (2) The friction torque is greater than the inner diameter with the resistance torque, to the force (Fx)
Therefore, the thrust bearing installation should pay attention to the following points.
(1) to distinguish between the bearing ring and loose ring (according to the bearing diameter to determine the diameter of the phase clear bearing tight ring and loose ring O.1 ~ O.5mm). Difference O.1 ~ O.5mm).
(2) to distinguish the static parts of the mechanism (that is not part of the movement, mainly refers to the separation of the body assembly of the static body).
(3) In any case, the loose ring of the bearing should always rest against the end face of the stationary element. Whatever the case.
