回転速度検出装置付転がり軸受ユニット
Document Type and Number:
Japanese Patent JP6417701
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a structure in which a cap fixed to an axial inner end part of an outer ring is prevented from being pushed toward an axial outer direction, and an axial position of the cap can be accurately restricted and an axial position setting accuracy between an encoder and a sensor can be easily assured.SOLUTION: A sensor unit 22a is fixed to a cap 18a under a state in which a holder main body 26a of a sensor unit 22a is directly inserted inside a sensor holding part 37 arranged at the first holding part 42 made of synthetic resin. In addition, the cap 18a is fixed to the outer ring 4 under a state in which a core bottom part 38 is positioned at an axial outside part. Then, under this fixed state, an axial outer surface of a core flange part 40 and an axial inner end surface of the outer ring 4 are axially abutted to each other through an annular covering 45, an axial position setting of the cap 18a in respect to the outer ring 4 is attained and at the same time, a detecting part of a sensor 50 is oppositely faced against the detected surface of the encoder 21 through the core bottom part 38.
