Reverse torque detection device and reverse torque detection method for one-way bearing

Abstract

The invention discloses a reverse torque detection device and reverse torque detection method for a one-way bearing. The device comprises a first fixture body, a second fixture body, a mandrel, four long bolts, and four nuts (5) matched with the long bolts, four short bolts and a fixing plate. According to the reverse torque detection device and reverse torque detection method for the one-way bearing of the invention, the first fixture body and the second fixture body are combined to fix the outer ring end surface of the one-way bearing; the mandrel and a ferrule are adopted to fix the inner ring end surface of the one-way bearing; since an end surface loading mode is adopted, the related drawbacks of the outer circle loading of a common detection device can be avoided; detected data obtained by the device of the invention are more realistic, stable and reliable; the fixing plate is used for fixing the mandrel when a hexagon bolt is tightened, and therefore, the inner ring of the bearing can be prevented from rotating with the mandrel when the inner ring of the bearing is clamped, so that a reverse torque applied to the inner ring of the bearing can be avoided indirectly; the fixing plate is removed before detection, so that the detection of the reverse torque of the reverse bearing is more realistic and reliable.

Description

technical field [0001] The invention relates to a reverse torque detection device and a reverse torque detection method of a one-way bearing. Background technique [0002] A one-way bearing is a bearing that can rotate freely in one direction, but produces a large drag distance (ie: reverse torque) in the other direction. [0003] When detecting the reverse torque of the one-way bearing, the prior art usually relies on the interference fit between the outer circle and the inner hole to obtain the static friction torque required to fix the inner ring and the outer ring of the one-way bearing. However, when the interference is too large or the one-way bearing is a thin-walled bearing, the design of this structure will often cause deformation or even damage to the internal structure of the bearing, making the final test data not true. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a reverse torque detection device...
