Abstract
A rotor rotation device the rotor of a crusher includes a drive mechanism comprising a worm shaft and corresponding worm wheel. The worm wheel can selectively be coupled to said rotor in order to effect controlled rotation of the rotor, e.g. to facilitate maintenance of the crusher. The worm shaft cannot be back-driven by the rotor which allows the drive mechanism to serve as a lock against unwanted or uncontrolled rotation of the rotor.
Claims20
A rotor rotation device for controlling rotation of a rotor of a material processing device, the rotor rotation device comprising:
- a drive mechanism;
- and
- means for selectively coupling the drive mechanism to the rotor,
- wherein said rotor rotation device is operable in a driving state in which said coupling means couples the drive mechanism to the rotor to allow rotation of said rotor by said drive mechanism, or in a non-driving state in which said coupling means does not couple the drive mechanism to the rotor,
- and wherein said drive mechanism comprises a worm shaft and corresponding worm wheel, said coupling means being configurable to selectively couple said worm wheel to said rotor.
