Problems solved by technology

[0002] Most of the gear transmission and bearing lubrication in the rocker arm of existing coal mining machines at home and abroad are lubricated by oil pools. When the rocker arm of the coal mining machine is working at the upper swing angle, the bearings and gears at the upper end of the rocker arm cannot be well lubricated. , the gears and bearings are severely worn, and the service life is greatly reduced

Embodiment Construction

[0008] The spline shaft of the original motor 6 is connected with the spline in the driving gear 5, and a forced lubrication gear pump 2 is added in the rocker arm. Driving gear 5 meshes. The oil suction port 1 of the gear pump 2 is connected to the oil pool in the inner cavity of the rocker arm, and the oil outlet 3 is connected to the oil pipe to deliver to the lubrication point to realize the forced lubrication of the rocker arm. The rocker arm motor of the coal mining machine rotates, and the driving gear, driven gear and gear pump rotate in turn, and the lubricating oil is sent to the gear and bearing of the head at the upper end of the rocker arm.

Abstract

The invention provides a built-in forced lubricating system of a rocker arm of a coal mining machine, which aims at solving the technical problem that when the rocker arm of the coal mining machine is operated in an upper oscillation angle position, a bearing and a gear at the upper end of the rocker arm can not be well lubricated, the bearing and the gear are severely worn out, and the service life is greatly shortened. The built-in forced lubricating system has the key points that a forced lubricating gear pump is arranged in the rocker arm, and a driven gear arranged on the input shaft of the pump is meshed with a driving gear arranged on the output gear of a motor. When the motor of the rocker arm of the coal mining machine rotates, the driving gear, the driven gear and the gear pump rotate in sequence to feed lubrication oil to the gear and the bearing at the head at the upper end of the rocker arm, therefore, the service life is greatly prolonged.

Description

technical field [0001] The invention relates to a lubricating system, especially a forced lubricating system in the rocker arm of a relatively large coal mining machine. Background technique [0002] Most of the gear transmission and bearing lubrication in the rocker arm of existing coal mining machines at home and abroad are lubricated by oil pools. When the rocker arm of the coal mining machine is working at the upper swing angle, the bearings and gears at the upper end of the rocker arm cannot be well lubricated. , gears and bearings are severely worn, and the service life is greatly reduced. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a built-in forced lubrication system for the rocker arm of a coal mining machine. [0004] The purpose of the present invention is achieved like this: it has a motor, and it is characterized in that: a forced lubrication gear pump is added in...
