Patent CA-2964077-A1 (CA)
Inventor: ESTRADA EDGAR ANDRES
IPC: E21B17/12
Filed: 2014-12-23
Abstract: A method and apparatus are provided for securing a protective sleeve or wear sleeve to a rotary component which is rotatable relative to a rotary seal, such that the wear sleeve is in relatively rotating sealing engagement with the rotary seal. The wear sleeve is secured to the shaft by wedging a lock ring between the wear sleeve and the shaft. Wedging action of the lock ring can be effected by wedging formations, such as tapered surfaces, configured for causing wedging of the lock ring in response to operator-induced axial movement of the lock ring relative to the shaft and/or the wear sleeve. Wedging of the lock ring can be effected by cooperating screw threads on the lock ring and the wear sleeve, so that an operator can tighten the sleeve on the shaft by application of torque thereto.
