Abstract: A spindle assembly includes a main housing, a spindle mounted for rotation within the housing, a wheel hub attached to the spindle, a coupling located adjacent to an inner end of the spindle, and a disconnect shaft located within a bore of the coupling. The disconnect shaft is moveable in an axial direction between an engaged position in which a splined portion of the disconnect shaft mates with splined portions of both the spindle and the coupling to prevent the spindle from rotating independently of the coupling, and a disengaged position that allows the spindle to free-wheel relative to the coupling. A sprocket or gear is connected to an inner end of the coupling to connect the spindle assembly to a drive motor. An actuator is connected to an inner end of the disconnect shaft to move the shaft between its engaged and disengaged positions.

Abstract: A conveyor pulley is configured to revolve about an axis of rotation and includes a cylindrical shell and first and second bushing portions supported within the shell. First and second shaft portions are in torque-transmitting engagement with the first and second bushing portions, respectively. Such first and second shaft portions are restrained from axial movement with respect to the first and second bushing portions, respectively, and the first and second shaft portions are spaced from one another. For repair, the shaft portions and related bearings are independently removable without removing the entire pulley from the conveyor system.
