Needle roller bearing and it can be installed, apply a thin layer of lubricating oil, the auxiliary sleeve diameter set into the bearing outer ring and the auxiliary sleeve and bearing outer ring form a circular hole, and then install needle in the annular...
In general, the proper use of imported bearings, the fatigue life can be achieved. But if the accident early damage, unable to use. And the fatigue life is different, this early damage, is called the fault or accident. Much due to the installation and...
Linear bearing technology determine the maintenance cycle of machinery and parts in the process of using the technology of state will gradually degenerate, leading to decline in reliability, ability to work some or all of the loss. In order to make the...
Bearing damage, often is not a single cause, but under the effect of several aspects comprehensive, under harsh operating conditions to produce vicious circle, cause serious loss of clutch bearing, so after the accident, it is often difficult to determine...
Four-point contact ball bearings in the process of heating device should pay attention to the following: A measure of the heating to master inappropriate, excessive temperature four-point contact ball bearings can damage, low temperature through the ring...
Generally speaking, the whole of the eccentric bearing rolling bearing itself does not produce noise. Often feel "bearing noise" is in fact the bearing directly or indirectly, with the surrounding structure vibration sound effects. This is why many times...
Bearing can be divided into: split rolling bearing, sliding bearing, bearing, flanged bearing, outside spherical bearing, etc. Bearing in use process should pay attention to what? (1) bearing the use of the cooling system. Bearing under the condition...
The results of numerical calculation and analysis to judge the stability of the bearing parameter Keq,, C2st and 8 st by bearing dynamic characteristic parameters dimensionless stiffness coefficient and damping coefficient of the dimensionless decision....
There are many types of fatigue, for rolling bearing is mainly refers to the contact fatigue. Rolling bearing ring each roller surface in contact stress under the action of repeated, the rolling surface of the metal from the metal substrate dot or flake...
Vibration may be caused by its frequency is approximately 1 KHZ under low frequency pulse (vibrating), may also be a frequency above 1 KHZ, few KHZ and even tens of KHZ high frequency vibration (natural vibration), usually contains both the above two...
