Common rolling bearing failure phenomena in general, there are two: First, bearing installation site temperature is too high, the second is the noise in the bearing operation. Today we will analyze the causes of these two failures, in order to facilitate everyone in the use of bearing more convenient.

A rolling bearing temperature is too high

The operation of the machine mechanical parts of the installation bearing allows a certain temperature, hand stroked institutions shell should not feel hot for the normal, and vice versa showed that the bearing temperature is too high. Rolling temperature mainly due to:

1, the lubricating oil quality does not meet the requirements or deterioration, the oil viscosity is too high;

2, mechanical assembly tight (gap);

3, the bearing assembly are tight;

4, the bearing ring rotation on the shaft or shell;

5, the load is too large;

6, bearing a cracked frame or rolling element.

Second, the rolling bearing noise

Rolling to allow a slight running sound at work, if the sound or unusual noise or crash, showed that the bearing failure. Rolling noise of the reason is more complicated analysis reveals the following reasons:

1, the bearing outer ring with the surface wear. Wear and tear damage bearings and housings, bearings and axes with the relationship, leading to the axis deviated from the correct position, abnormal sound in the high-speed movement of the shaft;

2, when the bearing fatigue, the surface metal peeling, but also make the bearing radial clearance increases to generate abnormal sound;

3, the bearing lubrication, the formation of dry friction, and bearing broken and will produce an unusual sound;

4, bearing wear Songkuang, the cage loose damage, also have abnormal sound.
