Reverse torque detecting device of one-way bearing

Abstract

The invention discloses a reverse torque detecting device of a one-way bearing. The reverse torque detecting device comprises a left clamp body, a right clamp body and a mandrel. The left clamp body and the right clamp body are the same in structure and are respectively provided with a plurality of threaded holes. Inner holes of the left clamp body and inner holes of the right clamp body are in clearance fit with the outer circle face of the one-way bearing. The left clamp body and the right clamp body are combined through fastening of bolts in the threaded holes of the left clamp body and the threaded holes of the right clamp body, and the outer ring end face of the one-way bearing is fixed. The mandrel is in clearance fit with an inner hole of the one-way bearing, the mandrel is a step shaft, one end of the mandrel is provided with a boss which can fix the inner ring end face on one side of the one-way bearing, and the other end of the mandrel is connected with a gasket for fixing the inner ring end face of the other side of the one-way bearing. The boss and the gasket are fixed to the inner ring end faces on the two sides of the one-way bearing respectively through the bolts. By means of the method, related defects of loading of an ordinary detecting device outer circle can be effectively avoided, and the detected data can be more true, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of bearing measurement, in particular to a reverse torque detection device of a one-way bearing. Background technique [0002] A one-way bearing is a bearing that can rotate freely in one direction and produces a large resistance distance (ie: reverse torque) in the other direction. [0003] When detecting the reverse torque of a one-way bearing, it is usually used to rely on the interference fit between the outer circle and the inner hole to obtain the static friction torque required to fix the inner and outer rings of the one-way bearing. However, when the interference is too large or when the one-way bearing is a thin-walled bearing, the design of this structure will cause deformation or even damage to the internal structure of the bearing, which will distort the final test data. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a reverse torq...
