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
The present invention relates to a kind of lubrication system, the forced lubricating system in the particularly relatively large rocker arm of coal mining machine.
Background technique
The lubricated oil sump that adopts mostly of existing rocker arm of coal mining machine middle gear transmission both at home and abroad and bearing is lubricated, when rocker arm of coal mining machine is in swash angle position work; the bearing of rocking arm upper end and gear can not get well lubricated, and gear and bearing wear are serious, and reduce working life greatly.
Summary of the invention
For overcoming the deficiency of prior art, the object of the present invention is to provide a kind of built-in forced lubricating system of rocker arm of coal mining machine.
The object of the present invention is achieved like this: it has motor, it is characterized in that: added the enforced lubricating gear pump in rocking arm, be arranged on driven gear and the driving gear engagement that is arranged on the motor output shaft on this pump input shaft.The rotation of rocker arm of coal mining machine motor, driving gear, driven gear and gear pump rotate successively, lubricant oil are delivered to the gear and the bearing of the head of rocking arm upper end.
Compared with prior art, the invention has the beneficial effects as follows: when rocker arm of coal mining machine was in swash angle position work, the bearing of rocking arm upper end and gear obtained well lubricated, and improve working life greatly.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Accompanying drawing is a schematic representation of the present invention.
Embodiment
Utilize the splined shaft of original motor 6 to connect, in rocking arm, added enforced lubricating gear pump 2, be arranged on driven gear 4 and driving gear 5 engagements that are arranged on the motor output shaft on this pump input shaft with driving gear 5 internal splines.The inlet port 1 of gear pump 2 is received the oil sump of rocking arm inner chamber, and oil outlet 3 connects oil pipe and is transported to lubricating point, realizes the pressure lubrication of rocking arm.The rotation of rocker arm of coal mining machine motor, driving gear, driven gear and gear pump rotate successively, lubricant oil are delivered to the gear and the bearing of the head of rocking arm upper end.
Claims (1)
1. built-in forced lubricating system of rocker arm of coal mining machine, it has motor, it is characterized in that: added the enforced lubricating gear pump in rocking arm, be arranged on driven gear and the driving gear engagement that is arranged on the motor output shaft on this pump input shaft.
