Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] like Figure 1-4 As shown, a spherical bearing for a single-cylinder hydraulic cone crusher includes an upper part 4 of the spherical bearing, a middle part 5 of the spherical bearing and a lower part 6 of the spherical bearing.

[0032] The spherical bearing upper part 4 is the polyamide plastic spherical bearing upper part, the spherical bearing lower part 6 is the polyamide plastic spherical bearing lower part, and the spherical bearing middle part 5 is the alloy structural steel spherical bearing middle part after quenching and tempering.

[0033] The upper part 4 of the spherical bearing is a lower semi-convex spherical shape, and a high-strength bolt mounting hole 21 is provided at the middle part.

[0034] The middle part 5 of the spherical bearing is a symmetrical upper and lower concave spherical shape, and the middle part 5 of the spherical bearing is prov...

Abstract

The invention discloses a spherical bearing of a single cylinder hydraulic cone crusher. The spherical bearing of the single cylinder hydraulic cone crusher comprises a spherical bearing upper part, a spherical bearing middle part and a spherical bearing lower part, wherein the spherical bearing upper part and the spherical bearing lower part are both manufactured by nylon materials. Compared with the prior art, the spherical bearing has the advantages of uniform contact, enlarging of contact area, low friction force, and small abradability.

Description

technical field [0001] The invention belongs to the field of mining machinery manufacturing, in particular to the field of hydraulic cone crusher manufacturing, in particular to the selection of spherical bearing materials for hydraulic cone crushers. Background technique [0002] Single-cylinder hydraulic cone crusher is a commonly used equipment for mining and crushing. The material to be crushed by the main engine is driven by the main shaft assembly around a fixed shaft under the force of the eccentric sleeve, so that the crushing wall of the cone crusher sometimes approaches and sometimes leaves the surface of the rolling mortar wall fixed in the frame, so that the ore In the crushing cavity, the ore is crushed by continuous impact, extrusion and bending. The material enters the crushing cavity through the feeding hopper installed on the upper part, and is discharged from the lower discharge port after crushing. [0003] The lower part of the main shaft assembly is eq...
