COMPLEX FLEXIBLE COUPLINGS WITH IMPROVED LOCK-ON FEATURES

摘要

A flexible coupling having hubs secured to aligned shafts and connected to one another through a flexible belt (111) surrounding the hubs. The exterior of the flexible belt (111) has axial and circumferential grooves (113, 115) that lie transverse to the opening of the axial groove (113). A cooperating metal retainer band (31) has respective pins (35) formed on its interior surface for insertion into the axial grooves (113) and rotation into the circumferential grooves (115), thereby fixing the retainer ring (35) in position with respect to the flexible belt (111) and coupling. Retention of the retainer band pin (35) within the circumferential groove (115) is insured by displacing the center line of the axial groove (113) from a plane perpendicularly bisecting an underlying projection of the flexible belt (111) and by lengthening the circumferential groove (115).
