Abstract

The invention discloses a transmission system of coal mine machinery, which comprises a power part used to provide power to the coal mine machinery; and the power part is a variable frequency motor (21) which is arranged at an appropriate position of the coal mine machinery body. The whole starting process of the variable frequency motor (21) does not produce impact torque, the variable frequency motor is smoothly started, to significantly reduce the vibration load that the transmission system bears when the coal mine machinery is started, so as to improve the transmission reliability and the working safety of the coal mine machinery. The invention also discloses the coal mine machinery which comprises the transmission system.

Description

technical field [0001] The invention relates to the technical field of coal mine machinery, in particular to a transmission system for coal mine machinery. The present invention also relates to a coal mining machine comprising the above transmission system. Background technique [0002] With the rapid development of my country's economic construction, coal and other industries continue to develop in the direction of mechanization and automation, and various coal mining and transportation equipment are more and more widely used in coal mining construction. [0003] The following takes the coal plow as an example to introduce a typical transmission system used in coal mining machinery. [0004] Please refer to figure 1 , figure 1 It is a schematic diagram of the structure of a typical coal plow. [0005] Coal plows are used for the mining and transportation of 1.0-2.0m thin coal seams in underground coal mines. As a "shallow cutting depth, multi-cycle" coal mining equipme...
