Title:
TORQUE-LIMITING LOCKNUT
Document Type and Number:
WIPO Patent Application WO2005025788
Kind Code:
A3
Abstract:
The locknut has properties for limiting a tightening torque on a shaft to a predetermined torque value. A first member is adapted for engagement (50) by a user. A second member having inner threads (78). At least one deflection wall in the first member for deflecting outwardly in response to a radial force. At least one deflecting element (85) in the second to exert a radial force against the deflection wall to disengage with the deflection wall at a torque level greater than the predetermined torque. In another embodiment, inner screw threads deflect to disengage outer screw threads a torque level greater than the predetermined level.
