Definitions
- the invention relates to a bearing for a crusher and a crusher, in particular a cone crusher or gyratory crusher.
- Such crushers are known, for example, from the publication EP 1 71 1 266 B1 and serve for the comminution of rocks or minerals into smaller particle sizes.
- the bearing is provided for causing a tumbling movement of a scrubber cone relative to the crusher shell, whereby a constantly opening and closing annular gap is formed between the crusher cone and the crusher shell, via which rocks can be taken up and smashed.
- the bearing accordingly comprises an eccentric bush which rotates about an axis.
- the eccentric bush is at least partially encased by a bearing bush or bushing, which is embedded in a housing.
- the present invention solves the problem by a bearing for a crusher, in particular for a gyratory or cone crusher, wherein the bearing
- a lubricant line for supplying lubricant to the bushing is embedded.
- the lubricant line is embedded in the rotating eccentric bushing and not - as is customary in the prior art - in the housing or in the bushing. This has a positive effect on the load capacity of the bushing and thus on the load capacity of the entire bearing than that an effective support surface of the bushing can be increased, since no longer a wing decreasing the bore in the bushing for the lubricant line is required.
- sufficient lubrication of the bushing and the eccentric bushing with a lubricant film can be ensured via the lubricant line in the eccentric bushing.
- the bearing is a plain bearing.
- the lubricant line is disposed within a wall forming the eccentric bushing.
- the lubricant line is designed as a bore, or as a blind bore, at the end of which a transverse channel is located with an outlet opening.
- the lubricant line extends in the axial direction or in a direction parallel to the axis direction to the center of the bearing viewed in the axial direction.
- the lubricant line is arranged in the installed state in the crusher above this center and the gravity for the distribution of the lubricant between the eccentric bush and the bearing bush is shared.
- the lubricant is an oil or a lubricant oil.
- the lubricant is introduced from below into the lubricant line and is conveyed against gravity to the outlet opening.
- the lubricant line extends along an axial direction within a wall of the eccentric bushing. It is also conceivable that the lubricant line extends spirally in the wall. However, an axially aligned lubricant line can be realized most easily and guarantees the most direct possible feed into the desired area.
- the outlet opening is spatially limited in the direction of rotation.
- the exit opening is guided and wetted during operation of the crusher along an inner side of the bushing always a portion of this inside.
- the output port supplies the bushing with fresh lubricant in areas during its circulation.
- the position of the outlet opening is oriented such that the outlet opening is prepositioned by a predetermined angle in the direction of rotation of the bearing relative to a load area, in particular a current load area, of the crusher or bush.
- the load range corresponds to that region on the bushing which is subjected to the greatest load during the tumbling motion of the crusher cone.
- the predetermined angle is less than 200 °, preferably less than 160 °, particularly preferably less than 120 °.
- the eccentric bush has a return in the region of the outlet opening for forming a collection point for the lubricant.
- this collection point it is possible to ensure the greatest possible distribution, in particular in the axial direction, of the lubricant between the bearing bush and the eccentric bushing.
- the exit opening and the return in particular form a hydrostatic pocket.
- an eccentric insert is preferably provided, which is arranged between the axis and the eccentric bushing.
- the eccentric insert In order to guide the distribution of lubricant or the flow of oil uniformly along the bushing and the eccentric insert, the eccentric insert is throttled in particular in order to produce a uniform oil pressure for the eccentric insert or the axle and the bushing. Furthermore, a lubricant supply in the eccentric insert in the axial direction, in particular upwards, limited, so that realize a throttling and can ensure the supply of the hydrostatic bag with lubricant. The result is a uniform lubricant supply for both bearings. According to a further embodiment of the present invention it is provided that the bearing has a means for conveying the lubricant in the lubricant line. With the aid of this agent, the lubricant can preferably be subjected to pressure in such a way that an uninterrupted supply of the lubricant can be ensured. For example, the agent is a pump.
- Another object of the present invention is a crusher with a bearing according to the invention. Further details, features and advantages of the invention will become apparent from the drawings and from the following description of preferred embodiments with reference to the drawings.
- the drawings illustrate only exemplary embodiment of the invention, which does not limit the inventive concept. Brief description of the figures
- FIG. 1 shows a bearing for a crusher according to an exemplary embodiment of the present invention along a sectional plane running parallel to the axial direction.
- FIG. 2 shows a bearing for a crusher according to the exemplary embodiment of the present invention from FIG. 1 along a sectional plane running perpendicular to the axial direction.
- a bearing 1 for a crusher according to an exemplary embodiment of the present invention in a sectional plane which is parallel to the axial direction shown.
- a crusher is to be understood as meaning a machine which is provided for the comminution of lumpy material, in particular rock, to smaller particle sizes.
- it is a cone breaker or gyratory crusher.
- the comminution takes place in an annular opening and closing annular gap between a crusher shell (not shown) and a crusher cone (not shown). The opening and closing of the annular gap takes place simultaneously on opposite sides of a crushing space.
- the bearing 1 has an eccentric bushing 2 in order to cause a tumbling motion of the crusher cone with respect to the crusher shell predetermined by an eccentric insert.
- the bearing 1 further comprises a housing 3 and a sleeve 6 arranged between the housing 3 and the eccentric bushing 2, the bushing 6 and the housing 3 being fixed.
- the eccentric bushing 2 comprises at one of its end faces a collar element which projects beyond the housing 3 in the radial direction.
- an eccentric insert 4 is provided, which rotates with the eccentric bushing 2 and is arranged between the axis 5 and the eccentric bushing 2.
- a lubricant line 7 is embedded within the eccentric bushing 2, in particular within a wall of the eccentric bushing 2. This eliminates the need for an otherwise in the bushing 6 required bore for an output port, which would be attributed to a recessed into the bushing 6 and the housing 3 lubricant line 7. As a consequence, the liner 6 loaded during operation of the crusher can increase its effective airfoil and thus counteract potential damage in the event of an overload.
- the lubricant line 7 preferably extends substantially parallel to the axis 5.
- An outlet opening 10 of the recessed into the eccentric bushing 2 lubricant line 7 is provided in particular on one of the bushing 6 facing outside of the eccentric bushing 2.
- the eccentric bushing 2 on its outer side to form a collection point for the lubricant has a return 8.
- the recess 8 and the outlet opening 10 form in particular a hydrostatic pocket.
- the lubricant can be introduced via the lubricant line 7, so that a sufficient and the largest possible lubricant supply for the bushing 6 can be ensured.
- the bearing 1 for a crusher according to the exemplary embodiment of the present invention from FIG. 1 is shown along a sectional plane perpendicular to the axial direction.
- the outlet opening 10 is extended by a predetermined th angle ⁇ ⁇ seen in the direction of rotation 9 of the eccentric bushing 2 is arranged in front of a load range of the crusher.
- the load region is preferably determined by the region with the open annular gap, via which the material to be comminuted is disposed between the crusher shell and the crusher cone.
- a load range is that region on the bushing which is currently exposed to the highest load during operation.
