Abstract
The present invention aims to provide a sensor cover capable of avoiding a pulser ring from being damaged by the sensor cover with excellent positional accuracy relative to the pulser ring or the like. The present invention provides a rolling bearing apparatus having a structure in which whereas an outer peripheral edge of a sensor main body 38 of a sensor cover 37 is folded to bend to an inner side of a bearing and a conical portion 39a as a fitting portion is formed at a folded to bend portion 39 thereof, a conical portion 40a as a fitted portion for fitting the fitting portion is formed at an inner peripheral surface 40 of an outer ring 31 and a position in an axial direction of the sensor cover 37 relative to a is pulser ring 15 is set to position by fitting the two conical portions.
Claims5
A rolling bearing apparatus comprising:
- a rotating ring having a flange for supporting a wheel;
- a fixed ring which is supported on an outer diameter side of the rotating ring concentrically with the rotating ring and is not rotated;
- a plurality of pieces of rolling members rollably provided between the rotating ring and the fixed ring;
- a pulser ring which is installed at an outer peripheral surface on one end side in an axial direction of the rotating ring and a magnetic property of which is changed alternately in a circumferential direction;
- a sensor cover made of a nonmagnetic material installed to an inner peripheral surface on one end side in the axial direction of the fixed ring by making one face thereof proximate to the pulser ring and closing a ring-like space between the fixed ring and the rotating ring;
- and
- a sensor supported by the fixed ring or a portion of a vehicle body is proximate to or brought into contact with other face of the sensor cover to be opposed to the pulser ring in the axial direction via the sensor cover;
- wherein an outer peripheral edge of the sensor cover has a folded portion folded to an inner side of a bearing and a fitting portion formed at least at a portion of the folded portion,
- wherein a fitted portion for fitting the fitting portion is formed at a predetermined position of the inner peripheral surface of the fixed ring, and
- wherein a position in the axial direction of the sensor cover relative to the pulser ring is set to position by fitting the fitting portion of the sensor cover to the fitted portion of the fixed ring.
