Engineering machinery and lubricating device thereof

Abstract

The invention discloses a lubricating device for lubricating a gear mechanism and an engineering machinery provided with the same. The lubricating device comprises a lubricant pump (2) driven by the gear mechanism (1), and the outlet of the lubricant pump (2) corresponds to the lubricating position of the gear mechanism (1) such that lubricant in the lubricant pump (2) can lubricate the gear mechanism (1). The gear mechanism (1) can automatically lubricate in working so as to efficiently avoid the condition of no lubricating while the gear mechanism (1) works; in addition, the lubricating device has smaller dependency on operators and can be less influenced by operator responsibility or personal factor, thus the reliability of the lubrication of the gear mechanism (1) can be remarkably improved, the service life of the gear mechanism (1) is prolonged, and the economical efficiency of the construction machinery provided with the gear mechanism (1) is improved.

Description

technical field [0001] The invention relates to the lubricating technology of engineering machinery, in particular to a lubricating device for lubricating gear mechanisms. In addition, the present invention also relates to a construction machine comprising the above lubricating device. Background technique [0002] Shearer is a large and complex system integrating machinery, electricity and hydraulic pressure, and is the core equipment of fully mechanized mining face. The working environment is harsh, and if a failure occurs, the entire coal mining operation will be interrupted, resulting in huge economic losses. With the development of the coal industry, the shearer has more and more functions, and its own structure and composition are becoming more and more complex. [0003] The main function of the shearer is to break coal and load coal. The walking box is a necessary part of the coal mining machine, and the gear in the walking box is an important part of the normal wal...

AI Technical Summary

Problems solved by technology

[0005] However, there are many problems in the above-mentioned gear lubrication method

For example: after a period of use, the worker forgets to refuel the oil tank, but the worker does not know that there is no oil in the oil tank; sharp increase in wear

Some shearers even have no lubricating device at all, resulting in a very short service life of the gears in the traveling part, causing the shearer to stop production, affecting the output and economic benefits of the mine

In addition, the frequent operation of the valve of the oil tank not only increases the difficulty of the operator, but also makes the efficiency and service life of the coal mining machine highly dependent on the operator's sense of responsibility and proficiency, and the reliability is low
