Embodiment Construction

[0010] Such as figure 1 As shown, the parallel shaft cone crusher of the present invention includes a main shaft 2, an eccentric sleeve 3 sleeved on the main shaft 2, a movable cone 4 installed on the top of the main shaft 2 and a concentric The large gear 5 and the balance ring 6 installed at the lower end of the eccentric sleeve 3, in order to ensure its sealing effect, a labyrinth seal is provided between the balance ring 6 and the contact surface of the movable cone 4 and the frame 1. 4 A fixed cone 7 used in conjunction with it is arranged on the periphery, a motor-driven transmission shaft 8 is horizontally arranged on the frame 1, and a small gear 9 meshing with the large gear 5 is fixed on the top of the transmission shaft 8; The outer circle and inner hole of the eccentric sleeve 3 are parallel eccentric structures, that is, the outer circle center line 11 of the eccentric sleeve 3 and the inner hole center line 12 are parallel and eccentrically arranged. The inner ho...

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 invention relates to a cone crusher, in particular to a parallel shaft cone crusher. Background technique [0002] Cone crushers are widely used in crushing operations in mining, construction and grinding industries. Because of their continuous crushing, compact layout, and high efficiency of crushing operations, 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, bottom single-cylinder hydraulic cone crushers, etc. The moving cone movement axis of the above cone crusher and the frame axis are at a certain angle. It is set for inclined and eccentric, and adopts a spherical thrust bearing to make the crushing parts form a circular swing to crush the material. Because the moving cone is placed eccentrically and obliquely, all bearing supports are on an inclined plane, and the processing and assembly are not easy to guara...
