Roller bearing radial clearance measurer for oppositely driven races

摘要

The outer (9) of two rails (5, 9) is diametrically alternately loaded. The radial displacement of the outer (9) w.r.t. the inner (5) race is measured in the load direction. A distance measurement system (2) exclusively measures the distance between two points. One point lies on the inner race's bone surface (17) and an axial roller bearing radius line. The other lies on the same radius line and on the outer race's outer surface (14). The measurement system operates independently of measurement point absolute positions. Electronic sensors acting in the same direction contact the outer surface and the inner bore. They are connected in summation formation and to an indicator.
