A kind of coal mining machine running wheel bearing which is convenient for maintenance

Abstract

The invention discloses a traveling wheel bearing of a coal mining machine which is convenient for maintenance. The inner ring of the bearing is connected with the traveling rotating shaft in the manner of axial and radial limiting, and is also clamped with the traveling rotating shaft. In this way, The bearing can be easily disassembled to improve the ability of maintenance and replacement. The present invention also provides a convenient detachable installation mechanism for the shearer running wheel bearing which is convenient for maintenance. The detachable installation structure can effectively ensure the safety of the bearing Easy installation and replacement performance. At the same time, even if the bearing seat is damaged, it is easy to replace the bearing seat, which ensures the modular performance, effectively improves the maintenance performance of the shearer, and reduces the maintenance cost of the shearer.

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 ...
