LOAD-MEASURING DEVICE FOR ROLLING BEARING UNIT, AND ROLLING BEARING UNIT WITH ENCODER FOR DETECTING REVOLUTION SPEED OF ROLLING MOTION ELEMENT

摘要

PROBLEM TO BE SOLVED: To assure the bonding strength of an encoder 26a for detecting the revolution speed for joint fixing to a holder 21a, in a structure which measures the load applied to a rolling bearing unit, based on the revolution speed of a rolling motion element. SOLUTION: The encoder 26a, for detecting the revolution speed which vulcanizes and adheres a rubber magnet 28 to a back yoke 29a, is insert molded on the outside surface part of a rim 25 for constituting the holder 21a. As a result, the bonding strength, durability and reliability of the encoder 26a for detecting the revolution speed to this holder 21a can be enhanced, as compared with the case of using an adhesive.
