Abstract

A gyratory cone crusher includes a first and a second crushing shell defining a crushing gap. The first crushing shell is arranged to gyrate around a vertical axis, in order to crush material entering the crushing gap, and is vertically supported by a thrust bearing including first and second bearing plates defining a spherical sliding interface. One of the bearing plates has one or more cooling and/or lubricating grooves at the sliding interface, each groove defining a channel, extending from the center of the sliding interface to the periphery thereof. In order to obtain a uniform distribution of grooves, the cooling/lubricating grooves are in the form of one or more spirals extending from the center of the sliding interface to the periphery thereof. The disclosure further relates to a bearing plate and a kit of bearing plates involving such a bearing plate.

First claim

The invention claimed is:

1. A bearing plate for a gyratory cone crusher, the bearing plate comprising:
one or more cooling/lubricating grooves at a surface of a sliding interface, each of the grooves defining a channel extending from a central portion of the sliding interface and opening to a periphery thereof, the channel having a uniform width without any intersections or forks, wherein the cooling/lubricating grooves are one or more spirals extending from the central portion of the sliding interface and towards the periphery thereof and forming a uniform distribution of grooves over the sliding interface.

2. The bearing plate according to claim 1 , wherein the cooling/lubricating grooves are interleaved spirals.

3. The bearing plate according to claim 2 , further comprising 6 to 10 spirals.

4. The bearing plate according to claim 1 , wherein each of the cooling/lubricating grooves defining the channel extend from an inlet at the central portion of the sliding interface to an outlet at the periphery thereof.

5. A bearing plate kit for a gyratory cone crusher comprising:
at least two bearing plates, each of the bearing plates including one or more cooling/lubricating grooves at a surface of a sliding interface, each of the grooves defining a channel extending from a central portion of the sliding interface and opening to a periphery thereof, the channel having a uniform width without any intersections or forks, wherein the cooling/lubricating grooves are one or more spirals extending from the central portion of the sliding interface and towards the periphery thereof and forming a uniform distribution of grooves over the sliding interface.

6. The bearing plate according to claim 5 , wherein each of the cooling/lubricating grooves defining the channel extend from an inlet at the central portion of the sliding interface to an outlet at the periphery thereof.
