Abstract
A cone crusher includes a frame, a shaft supported by the frame, and a head disposed on the shaft. An eccentric mechanism is coupled to the head. A one-way clutch is coupled to the shaft, and a friction torque limiting clutch is disposed within the head and coupled between the head and the one-way clutch.
Claims23
A cone crusher, comprising:
- a frame;
- a shaft supported by the frame;
- a head disposed on the shaft;
- an eccentric mechanism coupled to the head;
- a one-way clutch coupled to the shaft;
- and
- a friction torque limiting clutch disposed within the head and coupled between the head and the one-way clutch.
4 more elements
An anti-spin mechanism in combination with a rock crusher having a head, an eccentric, and a shaft, comprising:
- a one-way clutch coupled to the shaft, the one-way clutch permitting rotation of the head in a first direction, and inhibiting rotation of the head in a second direction;
- and
- a friction torque limiting clutch disposed within the head and coupled to the one-way clutch, wherein the friction torque limiting clutch protects the one-way clutch by permitting rotation of the head in the second direction in the case of an excessive torque loading.
A rock crusher, comprising:
- a stationary shaft;
- a head coupled to the shaft, the head driven in a gyratory manner by an eccentric;
- a lower spindle extending from the shaft;
- a backstop clutch coupled to the lower spindle;
- an upper spindle coupled to the backstop clutch;
- and
- a friction torque limiting clutch coupled between the upper spindle and the head.
4 more elements
A rock crusher, comprising:
- ahead;
- a stationary shaft;
- means coupled between the head and the shaft for permitting rotation of the head in only one direction;
- and
- means for limiting the torque on the means for permitting rotation of the head in only one direction, the means for limiting the torque comprising a number of plates that frictionally engage one another.
