Abstract
A gyratory crusher bearing arranged for carrying a crushing head of a gyratory crusher having an inner crushing shell supported by the crushing head, and an outer crushing shell supported on a crusher frame. The gyratory crusher bearing includes a lubricant supply channel and a lubricant drainage channel. At least one of the lubricant supply channel and the lubricant drainage channel is arranged for housing a combined mounting and lubricant passage bolt holding the gyratory crusher bearing to a bearing support arranged on the crusher frame of the gyratory crusher.
Claims15
A gyratory crusher bearing for carrying a crushing head of a gyratory crusher of the type having an inner crushing shell supported by the crushing head, and an outer crushing shell supported on a crusher frame, wherein the gyratory crusher bearing is connectable to a bearing support arranged on the crusher frame of the gyratory crusher, the gyratory crusher bearing comprising:
- a lubricant supply channel extending through at least a part of the gyratory crusher bearing and ending at a bearing surface of the gyratory crusher bearing;
- and
- a lubricant drainage channel extending through at least a part of the gyratory crusher bearing and starting at the bearing surface, wherein at least one of the lubricant supply channel and the lubricant drainage channel is arranged for housing a combined mounting and lubricant passage bolt holding the gyratory crusher bearing to the bearing support.
A gyratory crusher bearing arrangement comprising:
- a gyratory crusher bearing including a lubricant supply channel extending through at least a part of the gyratory crusher bearing and ending at a bearing surface of the gyratory crusher bearing and a lubricant drainage channel extending through at least a part of the gyratory crusher bearing and starting at the bearing surface;
- a bearing support;
- and
- a combined mounting and lubricant passage bolt arranged in at least one of the lubricant supply channel and the lubricant drainage channel of the gyratory crusher bearing and fixing the gyratory crusher bearing to the bearing support.
A gyratory crusher comprising:
- an inner crushing shell supported by a crushing head;
- an outer crushing shell supported on a crusher frame;
- a gyratory crusher bearing including a lubricant supply channel extending through at least a part of the gyratory crusher bearing and ending at a bearing surface of the gyratory crusher bearing and a lubricant drainage channel extending through at least a part of the gyratory crusher bearing and starting at the bearing surface;
- and
- a gyratory crusher bearing arrangement supporting the crushing head, the gyratory crusher bearing arrangement including a bearing support and a combined mounting and lubricant passage bolt arranged in at least one of the lubricant supply channel and the lubricant drainage channel of the gyratory crusher bearing and fixing the gyratory crusher bearing to the bearing support.
A method of mounting a gyratory crusher bearing for carrying a crushing head of a gyratory crusher including an inner crushing shell supported by the crushing head, and an outer crushing shell is supported on a crusher frame, the method comprising:
- arranging the gyratory crusher bearing on a bearing support arranged on the crusher frame of the gyratory crusher;
- inserting a combined mounting and lubricant passage bolt into at least one of a lubricant supply channel extending through at least a part of the gyratory crusher bearing f and ending at a bearing surface of the gyratory crusher bearing, and a lubricant drainage channel q extending through at least a part of the gyratory crusher bearing and starting at the bearing surface of the gyratory crusher bearing;
- and
- tightening the combined mounting and lubricant passage bolt to press the gyratory crusher bearing towards the bearing support.
