Abstract
Herein disclosed is a flexible gear type coupling for connecting a pair of substantially coaxially aligned shafts to transmit torque therebetween. The flexible coupling comprises a hub having external gear teeth surrounding an outer portion thereof and rotatably connected to one of the shafts. A sleeve surrounds the hub and has internal gear teeth surrounding an inner portion thereof and in meshing engagement with the external gear teeth of the hub. A shear spacer is connected between the sleeve and the other of the shafts for transmitting torque from the one shaft to the other shaft. The shear spacer is adapted to shear when excessive torque is applied thereto for protecting the coupling from being damaged from the excessive torque. A capturing device is interposed between the hub and the sleeve for maintaining the sleeve substantially concentric about the hub upon shearing of the shear spacer.
