Travelling part of split-cavity structure

Abstract

The invention relates to a travelling part with a split-cavity structure. The shell of the travelling part is provided with an oil pool, a connecting plate is fixed to the shell, an open cavity is defined by the lower part of the connecting plate and the front side wall of the lower part of the oil pool, and a driving shaft is supported on the shell through a bearing; a driving gear is externallymeshed with the driven gear, a travelling wheel and the driven gear are coaxially fixed, and the travelling wheel and the driven gear are correspondingly and rotationally connected to the same supporting shaft through bearings; the supporting shaft penetrates through the front side walls and the rear side walls of the connecting plate and the oil pool, the driving gear and the driven gear are located in an oil pool cavity, and the travelling wheel is located in the open cavity; and the front side wall and the rear side wall of a guide sliding shoe are arranged on the supporting shaft in a sleeving mode, and gaps are reserved between the guide sliding shoe and the connecting plate, and between the guide sliding shoe and the corresponding surfaces of the lower part of the oil pool. Accordingto the travelling part, the problems that the abrasion loss of the travelling part is serious and the service life of the whole equipment is short when a roller type mining machine is used for mininghigh-hardness and high-abrasion-resistance mineral materials can be solved.

Description

technical field

[0001] The invention relates to a running part of a drum mining machine, which is especially suitable for occasions where mineral materials are highly abrasive and the gear transmission parts and frictional sliding parts are seriously worn under the open transmission state of the walking part of the mining machine, and belongs to the technical field of underground mining machinery. Background technique

[0002] Figure 14 Shown is the existing drum type mining machine running part 9, on which a driving wheel 91, a running wheel assembly 92, a bearing seal 93, an oil hole 94 and a small oil box 95 at the top are provided. The driving wheel drives the traveling wheel assembly to rotate, and the driving wheel 91 and the traveling wheel assembly 92 are all arranged in the transmission cavity of the shell communicated with the external mineral dust environment, and the abrasive abrasion of the mineral material is serious to the wear and tear of the tooth surface of...
