Abstract
Embodiments disclosed herein provide a cone crusher having a mantle and a rotating eccentric that causes the mantle to gyrate from side to side with respect to a stationary frame to which is mounted a crusher lining. The cone crusher may include a thrust bearing having a first bearing ring rotating with the eccentric and a second bearing ring mounted to the frame, the first and second bearing rings being disposed immediately adjacent and facing each other, one of the rings having a plurality of spaced oil feeds and a first and a second set of ramps on a surface facing the other ring. The first and second set of ramps extend upwardly from each of the oil feeds in opposite circumferential directions.
Claims14
A cone crusher having a mantle and a rotating eccentric that causes the mantle to gyrate from side to side with respect to a stationary frame to which is mounted a crusher lining, comprising:
- a thrust bearing including a first bearing ring rotating with the eccentric and a second bearing ring mounted to the frame, the first and second bearing rings being disposed immediately adjacent and facing each other, one of the rings having a plurality of spaced oil feeds and a first and a second set of ramps on a surface facing the other ring, the first and second set of ramps extending upwardly from each of the oil feeds in opposite circumferential directions.
A thrust bearing for a bi-directional cone crusher having an eccentric that rotates with respect to a stationary crusher frame, comprising:
- a first bearing ring mounted to and rotating with the eccentric;
- a second bearing ring mounted to the frame and disposed immediately adjacent to and facing the first bearing ring, the second bearing ring having a plurality of spaced oil feeds, with first and second ramps extending slightly upwardly from each of the oil feeds in opposite circumferential directions;
- and
- an oil drain disposed between the upper extent of each of the first and second ramps.
A process for lubricating a thrust bearing for a cone crusher having an eccentric that rotates with respect to a stationary frame, comprising:
- mounting a first thrust bearing ring to the eccentric to rotate with the eccentric;
- and
- mounting a second thrust bearing ring to the stationary frame such that it is substantially parallel to and in close proximity with the first thrust bearing ring, wherein one of the thrust bearing rings includes a plurality of evenly-spaced lubricating oil feeds, and a plurality of ramps extending in each circumferential direction from the oil feeds.
A cone crusher having a mantle and a rotating eccentric that causes the mantle to gyrate from side to side with respect to a stationary frame to which is mounted a crusher lining, comprising:
- a thrust bearing including an upper bearing ring rotating with the eccentric and a lower bearing ring mounted to the frame, the upper and lower bearing rings being disposed immediately adjacent and facing each other, the lower bearing ring having a plurality of spaced oil feeds and a first set and a second set of upwardly-facing support surfaces, the first set and second set of support surfaces extending in each circumferential direction from each oil feed to provide thrust support depending upon the direction in which the upper bearing ring is rotating.
A process for lubricating a thrust bearing for a cone crusher having an eccentric that rotates with respect to a stationary frame, comprising:
- mounting a first thrust bearing ring to the eccentric to rotate with the eccentric;
- and
- mounting a second thrust bearing ring to the stationary frame such that it is substantially parallel to and in close proximity with the first thrust bearing ring, wherein the second thrust bearing ring includes a plurality of tilting members designed to tilt away from a direction of travel of the first thrust bearing ring, forming a ramp inclined in the direction of travel of the first thrust bearing ring, and providing a plurality of spaced lubricating oil feeds in the second thrust bearing ring.
