Abstract
An improved hub-locking device for conveyor pulleys including a spherically shaped collet having a centrally located bore for receiving a shaft and having an axially aligned slot extending through one side thereof permitting compression of the collet on the shaft, a hub attached to the end of the pulley and having an axially aligned tapered aperture for partially receiving the collet with the shaft therein, a clamping ring having a tapered aperture for partially fitting over the collet and a plurality of bolts for passing through holes in the clamping ring, for threading into the hub and for drawing the clamping ring toward the hub compressing the collet therebetween, causing the collet to compress and engage the shaft, the hub and the clamping ring.
Claims8
A hub-locking device for use in coaxially mounting each end of a cylindrical pulley to a shaft comprising:
- a generally spherically-shaped collet having a centrally located shaft receiving bore, a longitudinally extending slot passing through one side of said collet permitting compression of said collet around the shaft, and at least one radially extending lug;
- a hub for attachment to an end of the cylindrical pulley to be mounted and having a first axially tapered bore for receiving one axial extremity of said collet, said hub having at least one bolt-receiving tapped bore formed therein;
- a clamping ring having a second axially tapered bore for receiving an opposite axial extremity of said collet, said ring having at least one bolt-receiving bore formed therethrough;
- and
- bolt means passing through said bolt-receiving bore in said clamping ring for threading into said tapped bore to draw said clamping ring towards said hub to compress said collet into locking engagement with the shaft passing therethrough, said bolts also being engaged by said lug to prevent rotation of said collet with respect to said hub.
