Cone crusher

Abstract

The invention discloses a cone crusher which comprises a transmission shaft, a small cone gear, a big cone gear, a movable cone, a fixed cone, a main shaft, an eccentric shaft sleeve, a stand central sleeve barrel and a stand, wherein a floating type spherical bearing is arranged at the lower end of the movable coneand positioned between the movable cone and a plane bearing seat; the spherical surface at the upper part of the floating type spherical bearing and the spherical surface at the lower part of the movable cone form a spherical kinematic pair; the plane surface at the lower part of the floating type spherical bearing and the upper plane surface of the plane bearing seat form a plane kinematic pair; the main shaft is a cylindrical main shaft and is inserted into a cylindrical inner hole of the eccentric shaft sleeve to form a cylindrical kinematic pair; and the big cone gear is fixedly arranged at the upper part of the eccentric shaft sleeve. The cone crusher of the invention has the characteristics of simple structure, good manufacturability of manufacture and installation, low manufacturing cost, long service life of vulnerable parts, low energy consumption, high workingefficiency and low failure rate in the using process.

Description

technical field [0001] The invention belongs to the field of material crushing equipment, in particular to a cone crusher. Background technique [0002] The existing spring cone crusher and multi-cylinder hydraulic cone crusher belong to the same cone crusher, and their internal structure is basically the same, the main difference is that the latter uses multiple hydraulic cylinders instead of the former in the external safety device. multiple sets of springs. The structure of the existing spring cone crusher and multi-cylinder hydraulic cone crusher is as follows: figure 1 As shown, its main shaft 8 is a tapered main shaft, and the fixed spherical bearing 61 is fixedly installed on the plane bearing seat 7 . When the cone crusher is working, the motor 1 drives the transmission shaft 2 to rotate, and the small bevel gear 11 at the other end of the transmission shaft 2 drives the large bevel gear 3 to drive the eccentric shaft sleeve 9 fixedly connected to the large bevel g...

AI Technical Summary

Problems solved by technology

[0003] Since the existing spring-type cone crushers and multi-cylinder hydraulic cone crushers use fixed spherical bearings and conical main shafts, there are many disadvantages in the existing cone crushers, whether in manufacturing or in use, such as complex structures, manufacturing And the manufacturability of installation is not good, the manufacturing cost is high, the energy consumption is high, the work efficiency is low, especially the failure rate is high during use
