Abstract

The invention provides a rocker arm structure applying to a coal mining machine. The rocker arm structure comprises a motor, a straight tooth driving part and a torque splitting part, wherein the motor supplies power to the rocker arm structure; the straight tooth driving part comprises shaft assemblies connected with the motor; the torque splitting part comprises input channels, output channels and a connecting part; first gear assemblies of the input channels are connected with the shaft assemblies of the straight tooth driving part, second gear assemblies of the output channels are connected with the first gear assemblies of the input channels and the connecting part, and the connecting part is connected onto a drum. Correspondingly, the invention provides the coal mining machine. According to the technical scheme, the driving efficiency of a rocker arm driving system is improved by means of combination of straight tooth driving and torque splitting driving, and the rocker arm structure has the advantages of low failure rate, light mass, small size and low cost.

Description

technical field [0001] The invention relates to the field of heavy equipment, more specifically, to a rocker arm structure and a coal shearer. Background technique [0002] At present, in the transmission system of the rocker arm of the coal mining machine, the deceleration structure of straight teeth and planets is usually adopted. Among them, the front end of the rocker arm transmission system adopts a straight tooth transmission parallel to the rocker arm motor, and the end connected with the drum adopts a level or two-level planetary structures. Since the planetary structure is more complicated than the straight tooth structure, the failure rate of the planetary structure is high, and its mass, volume and cost are high. [0003] Therefore, how to solve the problem of transmission efficiency of the shearer rocker arm transmission system, and simplify the structure of the transmission system, thereby reducing the failure rate of the transmission system, has become an urge...
