Abstract
The utility model discloses an external cooling circulation system of a rocker arm speed reduction box of a coal mining machine, which comprises a left rocker arm speed reduction box and a right rocker arm speed reduction box. Cooling oil ports of the left rocker arm speed reduction box and the right rocker arm speed reduction box are connected with an oil cooler through a cooling circuit and a delivery pump. When the external cooling circulation system of the rocker arm speed reduction box of the coal mining machine is used, the cooling effect of lubricating oil of the rocker arm speed reduction box is remarkable, the lubricating effect of the lubricating oil can be improved, and the wear life of gears in the speed reduction box can be prolonged.
Description
Technical field
The utility model relates to a kind of quick cooling rocking arm speed reducer lubricant oil, guarantees the cooling recirculation system of lubricating quality.
Background technique
When the front arm speed reducer adopts speed reducer inside to install cooling tube additional lubricant oil is cooled off, when the rocker arm of coal mining machine lifting, can cause the variation of the area of contact of lubricant level and cooling tube, thereby influenced the cooling effect of lubricant oil, produce the oil temperature improves thereupon, viscosity reduces, significantly reduce lubrication effect, shortened the rocking arm speed reducer with and working life of component.
The model utility content
It is remarkable that technical problem to be solved in the utility model provides a kind of rocking arm speed reducer lubricant oil cooling effect, and the rocker arm of coal mining machine deceleration box that prolongs the wear-out life of speed reducer internal gear cools off the circulatory system outward.
In order to solve the problems of the technologies described above, the rocker arm of coal mining machine deceleration box that the utility model provides cools off the circulatory system outward, comprise left rocking arm speed reducer and right rocking arm speed reducer, the cooling hydraulic fluid port of described left rocking arm speed reducer and right rocking arm speed reducer is connected with the fluid cooler by cooling circuit and transfer pump.
The cooling circuit of described left rocking arm speed reducer and right rocking arm speed reducer is connected with transfer pump with described cooler by a solenoid directional control valve respectively.
Described transfer pump and coal winning machine heighten series connection of pumps.
Be provided with the oil return oil purifier in the described cooling circuit.
Be connected with relief valve in the described cooling circuit.
Described transfer pump is a gear pump.
Adopt the rocker arm of coal mining machine deceleration box of technique scheme to cool off the circulatory system outward, adopt transfer pump that lubricant oil in left rocking arm speed reducer and the right rocking arm speed reducer is extracted out respectively, outside speed reducer, adopt the fluid cooler to force cooling, and then in the pumped back speed reducer, make the reduction of lubricating oil temperature in the deceleration box, improve the working life of lubrication effect and speed reducer, the lubricating oil in the rocking arm not only can be cooled off in this loop, and can filter the fluid in the rocking arm.This cooling system can well solve the cooling problem of rocking arm speed reducer lubricant oil, and it carries out external pressure cooling to speed reducer lubricant oil, and cooling effect is remarkable, thereby has improved the lubrication effect of lubricant oil.Prolonged the wear-out life of speed reducer internal gear, the remarkable reduction of the temperature of speed reducer simultaneously, the excellent prevention effect has also been played in the damage of the component that the rising because of the speed reducer temperature is caused, is that be greatly improved the working life of whole speed reducer.
Effective effect of the present utility model:
1, rocking arm speed reducer lubricant oil has been realized external quick cooling, has improved lubrication effect;
2, each part of speed reducer, the working life of having improved speed reducer have effectively been protected;
3, automatic switchover left and right sides rocking arm lubricant oil cooling circuit is greatly improved complete machine automaticity and reliability.
In sum, the utility model makes rocking arm speed reducer lubricant oil cooling effect remarkable, thereby has improved the lubrication effect of lubricant oil by the rocker arm of coal mining machine external cooling recirculation system that slows down, and prolongs the wear-out life of speed reducer internal gear.
