Therefore, whether the thickness of the inner surface of the large rib of the inner ring and the base surface of the inner ring is uniform directly affects the quality of the bearing It is an important indicator, so it is necessary to test this indicator before the tapered roller bearing is put into use.

At present, the method used to measure the bearing error of the large rib of the inner ring of the tapered roller bearing is to place the inner ring on the workbench, press the detection head of the testing instrument on the base surface of the large rib, and then manually rotate For the inner ring, the axial error of the large rib of the inner ring is obtained by reading the value on the testing instrument. However, there are many defects in this detection method, as follows:

It is difficult to ensure the coaxiality of the inner ring in the process of manually rotating the inner ring, but only the error between the heights of the points on the same circumference on the base surface of the large rib of the inner ring can truly reflect the large rib of the inner ring. Axial error, so the result is that this detection method is less accurate.
