Description

Oil lubrication system
Technical field
The present invention relates to a kind of oil lubrication system.
Prior art
Wind-driven generator is arranged on badly area of climatic environment more, and the impact such as the lubricant oil climate temperature difference, humidity is larger. and in relatively remote area, maintenance is inconvenience very.At present, in the reason losing efficacy at gear-box, lack of lubrication accounts for 50%.
Existing wind power generation gear case lubrication system has comprised two-stage epicyclic transmission mechanism and one-level parallel drive mechanism, each driving mechanism all needs lubricious, therefore make the peripheral lube pipe of wind power generation gear case more, not only caused gear-box to take up room greatly and but also the impact of the climate temperature difference, humidity cause that oil temperature is low causes that the fault of lack of lubrication is multiple, and due to the monotony of exterior line specking, cause slow-speed of revolution planetary structure to lubricate every fault insufficient and that cause.At present wind turbine gearbox lubricating oil pump is arranged on gear-box inside more, only after dismounting front cover, just can keep in repair, renewal of oil pump, very inconvenient.
Summary of the invention
The object of this invention is to provide and a kind ofly can prevent the deficiencies in the prior art, prevent the shadows such as the climate temperature difference, humidity to, exterior line oil temperature is too low, the every fault that causes lack of lubrication to cause; Guaranteed again the sufficient lubrication of slow-speed of revolution planetary structure; Be easy to lubricating oil pump part can the oil lubrication system with repairing for convenience detach simultaneously.
Technological scheme of the present invention is: described oil lubrication system comprises lubricating oil pump, center tube and lube pipe, described lubricating oil pump is arranged in the mounting hole on the housing of wind turbine gearbox, the oil outlet tube of lubricating oil pump is provided with branch road, wherein a branch road communicates with the center tube that is arranged on axis inside, on the planet carrier of the one-level epicyclic transmission mechanism of wind turbine gearbox, be provided with the bearing oil circuit identical with planetary pinion quantity with tooth top oil circuit and be connected with center tube respectively, the all planetary gear bearings in outside of bearing oil circuit and primary planet pinion are logical, on tooth top oil circuit in planetary pinion and gear ring engagement place and planetary pinion and sun gear engagement place be provided with nozzle, the planetary pinion axle of secondary planetary gear driving mechanism is hollow, side is provided with opening, in the planetary pinion axle of described secondary planetary gear driving mechanism, be also provided with the oil circuit that twice make hollow space communicate with planetary gear bearing and planetary pinion end, on the secondary shell of wind turbine gearbox, being provided with oil circuit and a side communicates with the Yi Ge branch of the oil outlet of lubricating oil pump, opposite side communicates with the sun gear bearing lining of one-level epicyclic transmission mechanism and all planetary gear bearings in inner side of primary planet pinion, and this oil circuit has lateral line, the outlet of this lateral line faces the opening of the planetary pinion axle of secondary planetary gear driving mechanism, on three grades of housings, being provided with oil circuit and one end communicates with a branch line of lubricating oil pump oil outlet tube, the other end communicates with each bearing sleeve of parallel drive mechanism.The outer installment that lubricating oil pump is installed on housing has end cap, and the diameter of this end cap is greater than the diameter of whole lubricating oil pump.
This invention at work, by each pipeline, can realize lubricating driving mechanism bearing and gear engaging piece.The lubricating oil that lubricating oil pump is got is by the branch road separating, communicate with center tube and housing on pipeline access mechanism inside be lubricated.Because one-level planetary structure is because rotating speed is lower, in order to prevent each bearing, gear lubrication deficiency, adopted the pressure lubrication mode of carrying out; Oil circuit on secondary shell can be realized lubricating the sun gear bearing of one-level epicyclic transmission mechanism, and the lubricating oil spraying by lateral line enters the planetary pinion axle inside of secondary planetary gear driving mechanism, by the pipeline in axle, bearing and planetary pinion are splashed and add the mode that centrifugal oil swirling combines and be lubricated, the oil circuit of another on housing is realized the bearing lubrication to parallel drive mechanism.
Oil circuit of the present invention is all arranged on internal system, therefore can effectively prevent the impacts such as the transmission system climate temperature difference, humidity, and exterior line oil temperature is too low, the every fault that causes lack of lubrication to cause; Adopt multiple lubricating system, realized lubricating all bearings and gear; Lubricating oil pump is arranged in the mounting hole on housing, and the outer installment that lubricating oil pump is installed on housing has diameter to be greater than the end cap of lubricating oil pump, can when lubricating oil pump break down, pull down end cap and just lubricating oil pump can be removed, and is easy to repairing and the replacing of lubricating oil pump.
