Detection Of Radial Clearance Of Bearing

According to the functional characteristics of bearings and the differences in the application of operating conditions, after the selection of suitable bearing types, it is also necessary to carry out routine inspection of bearings, which includes the specification and processing accuracy of bearings, assembly parts, lubrication status, whether there is wear phenomenon of parts and so on. Of course, after checking the bearing, the following operations should also be carried out: first, to clean the bearing, the need to be careful is that SKF bearing with sealing equipment can avoid cleaning this link, because cleaning will intrude on the bearing internal foreign matter, affecting the normal use of bearings; Second, it is necessary to adhere to the monotony of bearings. For bearings to be cleaned, when the rust inhibitor is cleaned off the bearing, it is necessary to dry the bearing, otherwise it is easy to lead to the rust of the bearing; Three is to adhere to the lubrication of lubrication.

In addition to the check operation before bearing equipment, the radial clearance of bearings should also be tested. Radial clearance mainly includes the original clearance of bearings under natural conditions, the cooperative clearance caused by the change of the original clearance after bearing equipment, and the practical clearance formed under the effect of temperature and load. Because the size of radial clearance directly affects the operating temperature, oscillation and service life of SKF bearing, the detection of radial clearance of SKF bearing is particularly important. How to measure the radial clearance of different bearings?

1. The measurement of radial clearance should be measured with special instruments as far as possible. When there is no special instrument on hand, it can be measured with feelers and other things. When using the feeler ruler to measure, it should be careful that the roller should not be used to roll from the feeler ruler before the way to measure. When using the manual method of measurement, this method has higher requirements for the surveyor, and is a easy way to make mistakes, so it is generally not recommended to use.

2. For SKF multi-row bearings, the clearance requirements of each row are very high, and it is necessary to be all qualified.

3. In the measurement process, it should be ensured that the roller of the bearing falls into the bottom of the ditch.
