Background technique
As everyone knows, in the gear-box of wind power plant, often use planetary gear device and planet-cylindrical gears device, how the rolling bearing of planetary stage is lubricated and cools off the working life that directly has influence on gear-box.
At present, a kind of method commonly used is: in the process of work, make them regularly be immersed in the oil groove that is arranged in gear case body.The rotating speed of the structure of this lubricated and the type of cooling and bearing, the oblique position of the uni-drive gear box longitudinal axis, planet carrier, the bearing waiting time and the oil body or the like in oil groove is in close relations; In addition, because the maximum oil level in the uni-drive gear box is subjected to the restriction of rotor-side labyrinth sealed can not be too high, cause the stone submersion of planet wheel in oil groove limited, also can produce adverse influence the lubricated of planetary gear device and planet-cylindrical gears device and cooling.
Another scheme lubricated to planet wheel bearing and cooling is: by means of pipeline, nozzle and restricting orifice lubricating point is implemented the annular spray by oil transfer pump, perhaps bearing is carried out splash lubrication.This lubricating and cooling means, general structure more complicated often can only realize the lubricated and cooling on surface, very difficult working surface to bearing inside is lubricated and cools off.For example, in wind power plant, if each unit installed power is big more, just then planetary gear device and planet wheel bearing thereof are big more.Simultaneously, planet carrier can be slower around the rotational of self with the planet wheel of fit on, to such an extent as to the need oil mass of each bearing raises, when carrying out this side from the outside by means of annular spray or spray site when spraying splash lubrication, it usually is that double row bearing is positioned at outside roller that lubricant oil only arrives, particularly big and have four or more during the planet carrier of multirow star-wheel when the flange diameter that adopts, for lubricant oil, be difficult near planet wheel bearing from outer jet.
Recently, the lubricating oil path that also has the people in the planet wheel bearing pin, to be provided with, the terminal of lubricating oil path is a planet wheel bearing, though this lubricating system can improve the lubrication effect of planet wheel bearing, but, because planet wheel bearing pin surface hardness is higher, the annular oil groove processing difficulties on surface, the stress that produces in the processing even cause the distortion of planet wheel bearing pin.
Summary of the invention
The purpose of this utility model is: poor at the mode lubrication effect in the oil groove in the regular immersion gear case body that at present rolling bearing of planetary stage is adopted, adopt oil transfer pump lubricating point to be implemented the inaccessibility planet wheel bearing of mode of annular spray by means of pipeline, nozzle and restricting orifice, a series of problems such as processing annular oil groove difficulty during the lubricating oil path that especially is provided with in the planet wheel bearing pin provide the lubricating structure in a kind of new wind-driven generator wheel-box.
The purpose of this utility model is achieved in that the lubricating structure in a kind of wind-driven generator wheel-box, the lubricating oil path entry end of the oil outlet of oil transfer pump and casing is linked up, be provided with injection loop between the lubricating oil path of casing and carrier flange dish, injection loop enters carrier flange dish lubricating oil path through slide block entry end annular oil groove, lubricating oil path in carrier flange dish lubricating oil path and the planet carrier bearing pin is linked up, lubricating oil path terminal in the planet carrier bearing pin is a planet wheel bearing, it is characterized in that: planet carrier bearing pin one end is provided with the bearing pin gland, and carrier flange dish lubricating oil path is linked up by the lubricating oil path in bearing pin gland and the star frame bearing pin.
In the utility model: form an oil sump between bearing pin gland and bearing pin end, the lubricating oil inlet of oil sump is located on the bearing pin gland, and the lubricant oil of oil sump enters the lubricating oil path in the planet carrier bearing pin.
In the utility model: the outer rim of bearing pin gland is provided with annular oil groove, and the lubricating oil inlet of oil sump is located at the bottom land of annular oil groove.
In the utility model: the entry end of described injection loop is an annular oil groove, and the lubricating oil path entry end of the annular oil groove of entry end and casing is linked up; The outer wall of described slide block is provided with the outer ring oil groove that docks with injection loop, and the inwall of slide block is provided with the interior annular oil groove that docks with carrier flange dish lubricating oil path, and the bottom land of inside and outside annular oil groove is provided with the oilhole of communication.
Advantage of the present utility model is: owing to adopt oil transfer pump bearing to be implemented pressure lubrication in the lubrication system by each lubricating oil path, and lubricated reliable; Owing to be provided with the bearing pin gland in the bearing pin end, form an oil sump between bearing pin gland and bearing pin end, even breaking down appears in oil transfer pump in the work, the short time fuel cut-off, the oil lubrication of hoarding in the oil sump still can provide lubricated for the bearing of planet wheel; It is easy to process on bearing pin gland, injection loop, slide block annular oil groove to be set.
