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.

Abstract

The invention discloses a bearing system of mining machinery, and belongs to the technical field of bearing structures. The bearing system comprises an outer ring and an inner ring which oppositely rotate, wherein the inner ring is sleeved by the outer ring and is coaxial with the outer ring; a retaining frame is further arranged between the outer ring and the inner ring; a ring-shaped inner slide path which is arranged in the peripheral direction of the outer ring is arranged inside the outer ring; a ring-shaped outer slide path which is arranged in the peripheral direction of the inner ring is arranged outside the inner ring; a slide body is positioned between the inner slide path and the outer slide path; the slide body comprises a plurality of slide blocks which are of circular-arc-shaped structures; and an upper curved-surface body which correspondingly fits to the outer slide path and a lower curved-surface part which correspondingly fits to the inner slide path are arranged on the slide block. The bearing system is low in processing cost, is simple in structure, and is great in radial bearing force; and surface-contact sliding is used, so that the defects of a rolling bearing in the prior art are solved, and popularization and application of agricultural machinery and mining machinery can be met.

Description

technical field [0001] The invention relates to the technical field of bearing structures, in particular to a mining machinery bearing system. 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 sha...
