軸受装置および波動歯車装置
Document Type and Number:
Japanese Patent JP7224743
Kind Code:
B2
Abstract:
A bearing unit (1) is provided with a strain element (6) for torque detection. The strain element (6) is provided with a first annular part (7) attached to a rotation-side member, a second annular part (8) attached to a load-side member, and a plurality of ribs (9) serving as strained parts linking the first annular part (7) and the second annular part (8) together. One of an inner race (4) and an outer race (3) is integrally formed on the first annular part (7) of the strain element (6). Deformation, which occurs in the ribs (9) of the strain element (6) due to torque exerted on the rotation-side member from the load-side member, is detected by a strain gauge, etc., and converted to torque. The strain element for torque detection can be incorporated into a motor, a reducer, or another rotary propulsion unit without the need for a dedicated installation space and without the need for fastening fittings, etc.
