ROLLING BEARING HOLDER UNIT

WIPO Patent Application WO/2022/025076

A1

This rolling bearing holder unit comprises: a rolling bearing which includes an outer ring, an inner ring arranged coaxially with the outer ring on the inner periphery side of the outer ring, and a plurality of rolling elements arranged between the outer ring and the inner ring and which has a predetermined rotary axis; a bearing holder arranged so as to be brought into contact with the outer peripheral surface of the outer ring or the inner peripheral surface of the inner ring of the rolling bearing; and a distortion gauge including a resistor for detecting a distortion in the outer ring or the inner ring. The bearing holder includes a thick portion and a thin portion thinner than the thick portion. The distortion gauge is arranged in the thin portion. A preload that forms a predetermined contact angle is applied to the rolling bearing. The thick portion is arranged so as to be brought into contact with at least a region ranging from an intersection point between a straight line indicating the contact angle and the outer peripheral surface of the outer ring or the inner peripheral surface of the inner ring to a preload-side end surface that is an end surface of the outer ring or the inner ring closer to the intersection point.
