Embodiment Construction

[0010] Such as figure 1 As shown, the parallel shaft cone crusher according to the present invention includes the main shaft 2 vertically installed in the frame 1 at the lower end, the eccentric sleeve 3 sleeved on the main shaft 2, the movable cone 4 installed on the top of the main shaft 2 and the concentric The large gear 5 and the balance ring 6 installed at the lower end of the eccentric sleeve 3, in order to ensure the sealing effect, a labyrinth seal is arranged between the balance ring 6, the contact surface of the moving cone 4 and the frame 1, and the moving cone 4 is provided with a fixed cone 7 used in conjunction with it on the periphery, and a motor-driven transmission shaft 8 is horizontally provided on the frame 1, and the top of the transmission shaft 8 is fixed with a pinion 9 meshing with the large gear 5; The outer circle and the inner hole of the eccentric sleeve 3 have a parallel eccentric structure, that is, the centerline 11 of the outer circle of the e...

Abstract

The invention discloses a parallel-axis cone crusher. The parallel-axis cone crusher comprises a rack, a main shaft, an eccentric sleeve, a movable cone and a fixed cone, wherein the excircle and the inner hole of the eccentric sleeve are in parallel eccentric structures; the inner hole of the eccentric sleeve and the excircle of the main shaft form a cylindrical friction pair; the lower end of the cylindrical friction pair and the rack form a planar friction pair; the inner hole of the movable cone and the excircle of the eccentric sleeve form the cylindrical friction pair; a planar bearing is arranged at the top end inside the movable cone; the planar bearing and the upper plane of the main shaft form the planar friction pair. The parallel-axis cone crusher disclosed by the invention has the advantages that the excircle and the inner hole of the eccentric sleeve are designed into parallel eccentric structures, and the movable cone and the top of the main shaft are connected by the planar bearing, so that a parallel relationship between a movement axis of the movable cone and the axis of the rack is ensured, and difficulty of machining internal and external angles of the eccentric parts and assembling the components is reduced; and meanwhile, a problem that the conventional cone crusher cannot normally work due to inclined angle changes caused by abrasion with a shaft sleeve in a using process is also avoided.

Description

technical field [0001] The present invention relates to cone crushers, and more particularly to parallel axis cone crushers. Background technique [0002] Cone crushers are widely used in crushing operations in mining, construction, and grinding industries. Due to their continuous crushing, compact layout, and high crushing efficiency, they have been widely promoted in the crushing application industry. [0003] At present, cone crushers are mainly divided into spring cone crushers, multi-cylinder hydraulic cone crushers, and bottom single-cylinder hydraulic cone crushers. It is set for inclination and eccentricity, and a spherical thrust bearing is used to make the crushing parts form a circular swing to crush materials. Because the moving cone is placed eccentrically and obliquely, all bearings are supported on a slope, and the processing and assembly is not easy to ensure. In particular, it is difficult to control the machining angle of the inner and outer circles of the...
