Abstract

The invention discloses a coal mining machine traveling wheel bearing convenient to maintain. The inner ring of the coal mining machine traveling wheel bearing is connected with a traveling rotating shaft in an axial limiting and radial limiting mode, and the inner ring of the coal mining machine traveling wheel bearing and the traveling rotating shaft are arranged in a clamped mode, so that the bearing can be conveniently disassembled, and the maintenance and replacement capacity is improved. The invention further provides a convenient-to-disassemble mounting mechanism for the coal mining machine traveling wheel bearing convenient to maintain. The convenient-to-disassemble mounting mechanism can effectively guarantee the mounting convenience and the replacement performance of the bearing,meanwhile, even if a bearing seat is damaged, the bearing seat is convenient to replace, the modular performance is guaranteed, the maintenance performance of a coal mining machine is effectively improved, and the maintenance cost of the coal mining machine is reduced.

Description

technical field

[0001] Specifically, the invention relates to a traveling wheel bearing of a coal shearer which is convenient for maintenance, and relates to the related field of coal shearer parts. Background technique

[0002] At present, for the coal mining machine, due to the dust and scattered coal in the working place, the traveling mechanism of the coal mining machine will generate large vibration and dust when walking, which is very important for the bearing of the coal mining machine traveling mechanism. The requirements are relatively high. However, even if the bearing is the best in performance, it is often prone to wear and tear in the application of coal mining machines, which leads to the need to frequently replace or repair the traveling bearings of coal mining machines. However, the current bearings Generally, it is fixed in the bearing seat by means of interference fit, which makes it very difficult to maintain or replace. Damage occurs, and over time, the ...
