Description

Technical Field

[0001] The utility model relates to the relevant field of angular contact ball bearings, in particular to a device for measuring the protrusion amount of an angular contact ball bearing. Background Art

[0002] Angular contact bearings are a special type of bearings, which are mainly used to bear combined loads, namely radial loads and axial loads. Its characteristic is the angle between the line connecting the contact points of the steel ball and the raceway and the perpendicular line of the bearing axis in the radial plane (also called the contact angle). The protrusion of angular contact ball bearings refers to the distance between the same end faces of the inner and outer rings of the bearing under the action of axial preload. This parameter is crucial for the pairing and use of precision angular contact ball bearings. When producing angular contact bearings, an angular contact ball bearing protrusion measuring device is required to measure the protrusion of angular contact ball bearings.

[0003] When using the existing angular contact ball bearing protrusion measuring device, a measuring tool is usually used to place and fix the angular contact ball bearing for measurement. However, the existing measuring device can only perform fixed measurement on bearings of the same size, which reduces the practicality of the device. Therefore, we make improvements on this and propose an angular contact ball bearing protrusion measuring device. Utility Model Content
