Abstract
Description
Technical Field
[0001] The utility model relates to a detection device for the protrusion amount of an angular contact ball bearing. Background Art
[0002] The protrusion amount of an angular contact ball bearing refers to the radial clearance between the outer ring and the inner ring, specifically the distance difference between the contact point of the inner and outer rings and the central axis of the bearing. The protrusion amount of an angular contact ball bearing plays a very important role in both bearing design and use. The larger the protrusion amount, the greater the bearing capacity and bearing stiffness, but the friction and wear will also increase; the smaller the protrusion amount, the smaller the bearing capacity, but the friction is small and the rotation is stable. Under the standard requirements, generally, the relative protrusion height of the inner and outer rings needs to be measured under a specified load, for example, after the bearing is actually assembled. At present, there are various forms of measuring devices for measuring the protrusion amount of an angular contact ball bearing. For example, those using a mandrel to apply pressure and those using a clearance tooling to apply pressure cannot meet the measurement requirements of the protrusion amount and affect the detection effect.
