Embodiment Construction

[0019] The present invention will be further explained below in conjunction with the accompanying drawings.

[0020] Such as figure 1 and 2 As shown, the rocker arm device of the short-range transmission coal shearer of the present invention includes a rocker arm housing 21, and the rocker arm housing 21 is provided with a driving motor 22 and a gear transmission system.

[0021] The arm housing 21 is cast, and there are two rocker arm hinge ears 19 and a height-adjusting oil cylinder connecting ear 20 on the outside of the rocker arm housing 21. The rocker arm housing 21 is connected to the shearer body through the rocker arm hinge ear 19 Hinged together, the height-adjusting oil cylinder connecting ear 20 is connected with the height-adjusting oil cylinder to realize the swinging height adjustment of the rocking arm.

[0022] The drive motor 22 is a low-speed high-torque permanent magnet motor, the drive motor 22 is fixed by bolts, and the end of the drive motor 22 is prov...

Abstract

The invention discloses a rocker arm device of a short-distance transmission coal mining machine. The rocker arm device comprises a rocker arm shell, wherein a driving motor and a gear transmission system are arranged in the rocker arm shell; the driving motor is a low-speed large-torque permanent magnet motor; the gear transmission system comprises a torque input shaft, a first carrying shaft, a second carrying shaft and a torque output shaft; the torque input shaft is connected with an output shaft of the driving motor; the torque input shaft is provided with a first-stage transmission small gear; the first carrying shaft is provided with a first-stage transmission large gear and a second-stage transmission small gear; the second carrying shaft is provided with a second-stage transmission large gear and a third-stage transmission small gear; the torque output shaft is provided with a third-stage transmission large gear; the first-stage transmission large gear is meshed with the first-stage transmission small gear for transmission; the second-stage transmission large gear is meshed with the second-stage transmission small gear for transmission; the third-stage transmission large gear is meshed with the third-stage transmission small gear for transmission. According to the rocker arm device, the technical problems of a long transmission chain of a gear transmission system, a large heat dissipation amount and high energy consumption of an existing coal mining machine rocker arm device are solved.

Description

technical field [0001] The invention relates to the technical field of mining excavation machinery, in particular to a rocker arm device of a drum shearer with short-range transmission. Background technique [0002] The double-drum shearer is a coal mining machine widely used in the comprehensive mechanized coal mining face, and plays a pivotal role in advocating efficient, economical and safe coal mining methods. The double-drum shearer rocker arm device that is widely used now usually uses the power transmission mode of "three-phase asynchronous motor + three-stage gear reduction + planetary gear reduction + cutting drum". Although this traditional rocker arm power transmission method makes full use of the space of the rocker arm of the shearer, the disadvantages of this power transmission method are: 1. The power transmission method adopts three-stage gear and planetary gear reduction, The transmission chain is long and the mechanical efficiency is low; 2. The output spe...
