Abstract

The invention discloses an eccentric sleeve mechanism for a cone crusher. The eccentric sleeve mechanism comprises a central sleeve arranged on a frame, wherein an eccentric sleeve is arranged inside the central sleeve; a bearing assembly is arranged between the eccentric sleeve and the central sleeve; an eccentric bushing is arranged inside the eccentric sleeve; a moving cone spindle of the cone crusher passes through the eccentric bushing to be pressed on a supporting seat; a bearing III is arranged between the eccentric bushing and the moving cone spindle; a gear which is in engaged transmission with a bevel gear on a transmission spindle of the cone crusher is arranged at the lower end of the eccentric bushing; and a spherical supporting group is arranged between the lower end of the moving cone spindle and the supporting seat. Due to the adoption of a three-rolling bearing structure, the eccentric sleeve mechanism for the cone crusher has the advantages of reducing the friction coefficient between the eccentric sleeve and the central sleeve and between the eccentric sleeve and the moving cone spindle, improving the rotating speed of the eccentric sleeve, improving the crushing efficiency and yield of the cone crusher, prolonging the service life of the machine, reducing the using cost of equipment, and guaranteeing sufficient lubrication of the rolling bearings by adopting a mode of simultaneously lubricating up and down by a lubricating channel I and a lubricating channel II.
