The causes of bearing runout are many, so when a failure or accident occurs, the causes must be analyzed to find out the root cause of the accident, and then appropriate measures must be taken to deal with it according to the specific situation. The details are as follows.
Proof punching method
When the bearing running circle, sure shaft fine hole large, can be in the in the surface or bearing body hole to avoid, uniformly hit some kind of punching eye, to bump part to make up for the size change. This can temporarily solve the running problem.
Brush plating method
By plating, the metal chromium is plated directly on the shaft or bearing body to restore the basic size.
Adhesive method
When the shaft is worn or the bore of the bearing body is worn, it will cause the bearing to run. At this time, you can choose a suitable metal bonding agent and fill the contact area gap, and then solidify it to solve the problem. Here to remind, adhesive can only be used on the contact surface of close fit. For example, the inner sleeve of the bearing rotating with the shaft and the outer sleeve of the bearing rotating with the wheel.
Welding Turning Method
The worn part is filled in by welding and then machined to the proper size, thereby restoring the function of the part. However, this method should not be used for stress-sensitive parts because welding causes changes in the mechanical properties of the material and generates stress concentrations.
Set method
Set method is also a common method, that is, the first damage to avoid and with part of the material processing down, and then processing a set set in the shaft or bearing body, and then the mating surface processing to the appropriate size. The method needs to pay attention to the strength of the sleeve, and the damage to the shaft and bearing body, etc.
The above is a common method to restore the use of bearings, the key is still to analyze the shaft, bearing, bearing body wear causes, must eliminate these causes, the results of the treatment, will be used for a long time, such as reducing vibration, improve lubrication, improve the quality of bearings, etc.
