センサホルダ部を有する保護カバー、及び前記保護カバーを備えた軸受装置

Japanese Patent JP7044029

B2

To provide a protective cover having a sensor holder part that can eliminate post-processing to scrape and flatten a bearing surface against which a magnetic sensor abuts after insert molding.SOLUTION: A protective cover is composed of a fiber-reinforced synthetic resin body 1A and a metal ring body 1B integrated by the insert molding. The body 1A comprises: a disc part 2; a sensor holder part 4 having a formed sensor attachment hole 4A for holding a magnetic sensor; and a partition wall 5 which is a thinner wall thinner than other parts. A distance R1 (mm) from the rotary shaft center of a radial direction maximum position D of an inner wall which forms the sensor attachment hole 4A of the body 1A is R1≥R2-0.6 with respect to a distance R2 (mm) from the rotary shaft center of an inner peripheral surface 6A of a first cylindrical part 6 which is outside part of the ring body 1B. In the ring body 1B, an axial position F of the inner side end of a second cylindrical part 7 connected to the inward end of the first cylindrical part 6 and located on the radial direction outside of the radial direction maximum position D, is located on the inner side of the axial direction center position of the disc part 2.SELECTED DRAWING: Figure 4
