Abstract
A conveyor idler includes a sleeve having an outer surface and an inner surface, a shaft about which the sleeve can rotate in a forward direction, a locking mechanism for preventing the sleeve from rotating in a reverse direction, but which locking mechanism permits rotation of the sleeve in the forward direction, the locking mechanism being located within the sleeve and having a shaft member fixed to the shaft, with at least one locking member which can move between an unlocked position in which the sleeve can rotate in the forward direction and a locked position in which the locking member locks the sleeve to the shaft member to prevent rotation of the sleeve in the reverse direction.
Claims18
A An arrangement comprising:
- a conveyor belt, and
- a conveyor idler including:
- a sleeve having an outer surface and an inner surface, the conveyor belt being supported on and arranged to run on the outer surface of the sleeve,
- a shaft about which the sleeve can rotate in a forward direction,
- a locking mechanism for preventing the sleeve from rotating in a reverse direction, but which locking mechanism permits rotation of the sleeve in the forward direction,
- the locking mechanism being located within the sleeve and having a shaft member fixed to the shaft, with at least one locking member which can move between an unlocked position in which the sleeve can rotate in the forward direction and a locked position in which the locking member locks the sleeve to the shaft member to prevent rotation of the sleeve in the reverse direction thereby causing the outer surface of the sleeve to provide a braking effect on the conveyor belt.
A An arrangement comprising:
- a conveyor belt, and
- a conveyor idler having including:
- an outer surface and an inner surface, the conveyor belt being supported on and arranged to run on the outer surface of the conveyor idler,
- a shaft about which the conveyor idler can rotate in a forward direction,
- a braking mechanism for preventing the conveyor idler from rotating in a reverse direction, but which braking mechanism permits rotation of the conveyor idler in the forward direction,
- the braking mechanism being located within the conveyor idler and includes at least one brake element which can move between a first position in which the conveyor idler can rotate in the forward direction, and a second position in which the brake element prevents the conveyor idler from rotating in the reverse direction thereby causing the outer surface of the conveyor idler to provide a braking effect on the conveyor belt.
