Hub module of mining equipment

Abstract

The invention discloses a hub module of mining equipment, and belongs to the technical field of bearing structures. The hub module comprises an outer ring and an inner ring for oppositely rotating; the inner ring is sleeved in the outer ring, and is coaxially arranged with the outer ring; a cage is arranged between the outer ring and the inner ring; a flange with a mounting hole is arranged at one end of the outer ring; the other end of the outer ring is leveled with the axial end surface of the inner ring; an annular inner slide way is peripherally formed in the inner side of the outer ring; an annular outer slide way is peripherally formed in the outer side of the inner ring; a slide body is arranged between the inner slide way and the outer slide way; the slide body comprises multiple slide blocks with arc structures; the slide blocks are provided with upper curved surface parts bonded corresponding to the outer slide way, and lower curved surface parts bonded corresponding to the inner slide way; a baffle plate is arranged in a shaft hole, at one end of the flange, of the outer ring; the baffle plate is extruded and pressed with the outer ring through a stop retainer ring; and the baffle plate is provided with an annular projection in interference fit with the axial end surface of the inner ring. The hub module adopts a full-contact surface rolling body, and can satisfy the use demands of a rotating part with low speed, heavy load and high load change in the process.

Description

technical field [0001] The invention relates to the technical field of bearing structures, in particular to a hub assembly of mining equipment. Background technique [0002] In mining operations, mining equipment is faced with the harsh working environment, such as mining machinery and mineral processing machinery. The transmission has the characteristics of heavy load, low speed and large load change during use. Due to the large load change during use, the load is large The vibration and impact caused by the time will cause the wear and fracture of the rotating parts, such as bearing wear or gear wear and fracture. At the same time, due to its special working environment, external mud, sand, water, etc. can easily enter the interior of the machine, including the bearing part, thereby aggravating the wear of the bearing and shortening the service life. [0003] Bearings are mainly used to support the shaft and the parts on the shaft, maintain the rotation accuracy of the sh...

AI Technical Summary

Problems solved by technology

In the prior art, sliding bearings can meet the conditions of heavy loads and large load changes, but sliding bearings cannot provide better axial support; although rolling bearings have small frictional resistance, sensitive starting, high efficiency, simple lubrication and easy replacement And other advantages, but its shortcomings are also obvious, its impact resistance is poor, it is not suitable for low speed, heavy load, and large load changes in the process of mining machinery and equipment.
