Thrust bearing assembly main axial load, wide application. Although the thrust bearing installation operation is relatively simple, but the actual repair is still often an error occurs, the tight and loose ring bearing ring mounting location that is incorrect, the results of the bearing out of action, the journal soon be worn. Tight inner ring and the journal for the transition fit, driven tight ring when the shaft is rotated, and the end surface friction with the stationary member in the axial direction by the force (Fx), it will appear with the friction torque is greater than the inner diameter of the drag torque, resulting in tight ring and the shaft with the face mandatory rotation, increased wear journal.
Therefore, the thrust bearing installation should pay attention to the following points.
(1) distinguish between the bearing ring and loosen tight rings (according to the size of the bearing bore determine the pore size difference O.1 ~ O.5mm).
(2) to distinguish between stationary member bodies (ie moving parts does not occur, mainly refers to the assembly).
(3) No matter what the circumstances, bearing the loose ring should always be against the end face of the stationary member.
