Embodiment Construction

[0012] The rocker arm of the drum shearer includes a rocker housing 7 and a reduction transmission system. The reduction transmission system is composed of a planetary reducer 3 located at the inner head of the rocker housing 7. The coal mining The rocker arm also includes a low-speed high-torque permanent magnet motor longitudinally arranged below the planetary reducer 3 in the rocker arm housing 7. The permanent magnet motor includes an inner rotor 8 and an outer stator 9. The permanent magnet motor is fixed on the The spline shaft 10 at the center of the inner rotor 8 is drivingly connected with the planetary reducer 3 .

[0013] During specific implementation, the spline shaft 10 includes a shaft with a longitudinal groove on the outside and a rotating member sleeved on the shaft and rotating synchronously with the shaft. The output shaft of the permanent magnet motor is the shaft of the spline shaft 10 , and the input shaft of the planetary reducer 3 is the rotating p...

Abstract

The invention relates to the field of drum-type coal cutter components, and particularly relates to a drum-type coal cutter rocker arm. The rocker arm comprises a rocker arm shell and a speed reduction transmission system, wherein the speed reduction transmission system is composed of planetary reducers arranged at the head part inside the rocker arm shell; the coal cutter rocker arm further comprises a low-speed large torque permanent magnet motor which is vertically arranged below the planetary reducers in the rocker arm shell; the permanent magnet motor comprises an inner rotor and an outer stator; the permanent magnet motor is in driving connection with the planetary reducers through a spline shaft which is fixedly arranged in an inner rotor shaft core. The drum-type coal cutter rocker arm provided by the invention is novel in structure and smart in design; the permanent magnet motor having the characteristic of large torque is adopted to take the place of an asynchronous motor with high speed and small torque; and meanwhile mechanical transmission chains of the speed reduction transmission system between a cutting drum and the permanent magnet motor are eliminated; components in the rocker arm can be lubricated constantly no matter how severely the coal cutter rocker arm is tilted, so that the service life of the coal cutter rocker arm is prolonged.

Description

technical field [0001] The invention relates to the field of drum shearer components, in particular to a rocker arm of a drum shearer. Background technique [0002] In the conventional drum shearer, the rocker arm of the shearer (such as figure 1 As shown), the head end is used to install the cutting drum 1, and the tail end is hinged to the shearer body. The rocker arm of the shearer includes a rocker housing 7 and a reduction transmission system. The reduction transmission system includes a planetary reducer 3 and a gear reduction transmission part. The inner head of the rocker housing 7 is provided with a cutting drum 1 connected to the planetary reducer 3, the middle part is provided with a gear reduction transmission part, and the tail is provided with a high-speed, low-torque asynchronous motor 2 connected to the gear reduction transmission part. The gear reduction transmission part includes sequentially connected from head to tail Three shafts 4 of gear transmis...
