Title:
COMBINATORY LOCKNUT HAVING SELF REACTION FORCE AND HIGH PRECISION TORQUE COEFFICIENT
Document Type and Number:
WIPO Patent Application WO/2017/181736
Kind Code:
A1
Abstract:
A combinatory locknut having self reaction force and a high precision torque coefficient, comprising a slotted nut (1), a washer (2), and a screw threaded ring (3). When a working bolt is tightened, the screw threaded ring is embedded between the washer and the bolt as a wedge ring so as to effectively prevent the loosening of the connection between the working bolt and the nut. The locknut enables precise preload for the installation of a bolt when the coefficient of friction is relatively small, and prevents loosening during machine operation.
