Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, in particular to a device for measuring the parallelism difference of the non-reference side rib of the outer ring of a double rib cylindrical roller bearing. Background Art

[0002] Usually, when detecting the reference side rib of the outer ring of a double rib cylindrical roller bearing, the reference surface of the product faces down and contacts the platform, and the measuring gauge extends from the upper end to contact the reference rib for measurement. However, due to the interference between the non-reference rib and the measuring gauge rod, the measuring gauge cannot directly detect the parallelism difference of the non-reference rib. Each time the parallelism difference of the non-reference rib is detected, the product is flipped 180°, and the non-reference surface of the product faces down and contacts the platform. However, this does not conform to the measurement principle and will also affect the measurement accuracy. Summary of the Utility Model
