Apparatus for determining movement of rolling body of bearing, particularly roller bearing, has annular coil for detecting change in magnetic field of rolling body during rotation of body of rolling body

摘要

The apparatus has a magnetic field fixed at the body of a rolling body (5), where an annular coil (12) detects a change in the magnetic field of the rolling body during the rotation of the body of the rolling body. The magnetic field is arranged substantially perpendicular to the intrinsic rotation axis (6) of the rolling body. An independent claim is also included for a method for determining the movement of a rolling body of a bearing, particularly roller bearing.
