Description

Technical Field

[0001] This utility model belongs to the field of bearing testing technology and relates to a spring washer parallelism testing device. Background Technology

[0002] Bracket bearings are used in automotive EPS systems and consist of a bearing, housing, gaskets, and spring washers. The spring washers are used to preload the bearing. After assembly, one side of the spring washer is flush against the bearing end face, while the other side is positioned against the housing. Therefore, if the parallelism of the two sides of the spring washer is out of tolerance, it will cause the bearing to be installed tilted, subjecting the bearing to additional bending moments and affecting its operation. Currently, the method for detecting the parallelism of spring washers is to use a height gauge, using one side as a reference, and randomly checking different points on the other side to determine if the parallelism is out of tolerance. This method cannot perform continuous circumferential testing, leading to misjudgments. Summary of the Invention
