Abstract
The utility model provides a high-dipping coal-cutter rocker-arm forced lubrication device. The high-dipping coal-cutter rocker-arm forced lubrication device comprises a gear pump, a motor, a driving gear, a transmission gear and a gear shaft, the driving gear is meshed with the transmission gear which is meshed with the gear shaft, the shaft end of the gear shaft is connected with the gear pump in linkage mode, the gear pump is located on the side face of one side of a worked out section of a rocker arm, the position of the gear pump on the high-dipping coal-cutter rocker arm is adjusted by means of meshing of the transmission gear and the gear shaft, and empty suction of the gear pump is avoided. The high-dipping coal-cutter rocker-arm forced lubrication device has the advantages that lubrication is reliable, maintenance and replacement are convenient, work efficiency of the gear pump is improved, service life is long, and performance of a high-dipping coal cutter is greatly improved.
Description
Technical field
The utility model relates to coal mining equipment, specially refers to a kind of high-dipping rocker arm of coal mining machine forced lubrication device.
Background technique
when coal-winning machine is mined at the high-dipping coal-face, be subjected to the impact of seam inclination, gear on rocking arm and bearing can not get effectively lubricated, for the gear on the raising rocking arm and the service life of bearing, must carry out forced feed lubrication to it, existing rocker arm of coal mining machine forced feed lubrication mode, it is the other forced feed lubrication gear pump that arranges of motor on rocking arm, by the driving gear on motor output shaft, driven gear on driven gear pump power shaft, make gear pump carry out forced feed lubrication to rocker arm of coal mining machine internal gear and bearing, but in the high-dipping coal-face, lubricating oil in rocker arm of coal mining machine is under Action of Gravity Field, can be gathered in the cylinder end in rocking arm, during the cylinder end of grease in rocking arm, fluid in rocking arm is far away apart from gear pump, existing gear pump because of the lubricating oil liquid level lower than the pump center, after starting, suction can occur, while causing gear pump to start, there is a bit of time to produce dry friction and cause wearing and tearing, even can inhale not oil-feed, affect life-span and the result of use of gear pump, and original gear pump is arranged on rocking arm inside, during damage, change very trouble.
Summary of the invention
The purpose of this utility model is for existing deficiency, and a kind of high-dipping rocker arm of coal mining machine forced lubrication device is provided, and is lubricated reliable, installs and changes conveniently, makes the gear pump high working efficiency, long service life.
The technical solution of the utility model is achieved in that a kind of high-dipping rocker arm of coal mining machine forced lubrication device, mainly comprise gear pump, motor, driving gear, driving gear, gear shaft, driving gear and driving gear engagement, driving gear and gear shaft engagement, the axle head of gear shaft connects with gear pump, and gear pump is positioned on the side of rocking arm goaf one side.
A kind of high-dipping rocker arm of coal mining machine forced lubrication device that the utility model provides, pass through driving gear, with the engagement of gear shaft, adjusted the position of gear pump on the high-dipping rocker arm of coal mining machine, make gear pump in the high-dipping rocker arm of coal mining machine, no matter rocker arm of coal mining machine is upwards or downwards, fluid in the high-dipping rocker arm of coal mining machine can be dipped into the gear pump center all the time, avoids the gear pump suction, and gear pump is positioned at rocking arm goaf one side, during damage, change very convenient.
The beneficial effects of the utility model are: a kind of high-dipping rocker arm of coal mining machine forced lubrication device that provides, and lubricated reliable, convenient maintenance and replacement, the gear pump working efficiency improves, and long service life is largely increased the performance of high-dipping coal winning machine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, and as shown in Figure 1: a kind of high-dipping rocker arm of coal mining machine forced lubrication device comprises gear pump 1, motor 2, driving gear 3, driving gear 4, gear shaft 5.Motor 2 output shafts connect with driving gear 3 by key, driving gear 3 and driving gear 4 are meshed, driving gear 4 is meshed with gear shaft 5, axial end at the worked-out section side of gear shaft 5 is holed, and keyway is set in the hole, and gear pump 1 passes through key, link with gear shaft 5, during work, the motor 2 on the rocking arm rotates, and the energy of output drives driving gear 3, driving gear 4, gear shaft 5 rotates successively, gear shaft 5 supply gear pumps 1 power of rotation, gear pump 1 is started working, draw lubricant oil, pass through lubrication piping, gear on the rocking arm and bearing are carried out pressure lubrication, gear pump 1 is positioned at rocking arm goaf one side, during damage, changes very convenient.
