How to check the tightness of rolling bearing and shaft shoulder?

Normally, a rolling bearing with a tight fit and an interference fit must abut against the shaft shoulder. So, how to detect the closeness of the rolling bearing and the shaft shoulder? Below Langche Bearing shares 2 methods.

1. Lighting method

The lighting method is very simple, that is, align the electric light at the bearing and the shaft shoulder, and judge the light leakage situation.

If there is no light leakage, it means the installation is correct; if the light leaks evenly around the shoulder, it means that the bearing is not close to the shoulder, and pressure should be applied to the bearing to make it close; Or tap the inner ring of the bearing with the sleeve, and slowly set it right.

2. Thickness gauge inspection method

1) The thickness of the thickness gauge should start from 0.03mm. During the inspection, try inserting several places on the entire circumference of the end face of the bearing inner ring and the shaft shoulder. If there is a gap and it is uniform, it means that the bearing is not installed in place, and the inner ring of the bearing should be pressurized to make it close to the shaft shoulder;

2) If the pressure is increased and it is not tight, it means that the fillet of the journal fillet is too large and the bearing is stuck, and the journal fillet should be trimmed to make it smaller;

3) If it is found that the thickness gauge of the end face of the bearing inner ring and the individual parts of the bearing shoulder can pass, it means that it must be disassembled at this time, trimmed and reinstalled.

4) If the bearing is installed in the bearing seat hole with an interference fit, when the outer ring of the bearing is fixed by the shoulder of the housing hole, whether the end face of the outer ring is close to the end face of the shoulder of the housing hole, and whether the installation is correct, the thickness gauge can also be used. test.
