Description

A kind of lubrication system of wind turbine gearbox
Technical field
The present invention relates to the lubrication technical field of gear-box, particularly a kind of lubrication system of wind turbine gearbox.
Background technique
Lubrication system is the important component part of wind turbine gearbox, and its structural type is to service behaviour, the operational security of gear-box and produce material impact working life.According to statistics, in the fault of wind power gear, about 75% fault is directly or indirectly caused by lubrication system fault, spot corrosion as bearing was lost efficacy, and normally because the load of raceway is excessive, added friction effect, cause the temperature rise aggravation of raceway contact position, if lubrication system now can not take away heat by heat exchange in time, bearing temperature can exceed allowed band, and bearing was lost efficacy rapidly.For gear, common failure mode is tooth face agglutination, spot corrosion and corrosion etc., and these failure modes are also closely bound up with the lubrication state of contact points.Therefore, how by lubrication system, economical, effectively lubricant oil is transported to each crucial lubricating point, be the key improving gear-box reliability.
Form that is outside at gear case body and inner stringing is generally taked in current lubricating pipe design, does not substantially utilize the structural member of gear-box inside, as planet carrier and casing etc.The shortcoming of this design is: not only cost is high for (1) internal lubrication stringing, too increases weight simultaneously: (2) stringing is more. the circuit that lubricant oil flows through is longer, and lubrication pressure loss is larger, causes added power dissipation; (3) stringing it is also proposed requirements at the higher level to gear-box inner space; (4) stringing often causes excessive, the overweight design of casing to the demand in space; (5) stringing is more, and interface is also more, adds the risk that lubrication system is revealed and reduced pressure.Therefore, for gear-box, design one can reduce expense cost, can ensure good sealing property again, and then the lubrication system improving lubrication system reliability is very important.
The patent of invention (application number is " 201110421140.2 ") of " oil lubrication system " of the application of Harbin Dongan Engine Co., Ltd, feature utilizes on the component such as planet carrier to arrange oil circuit, replace part stringing, save cloth tube space, but fail to make full use of gear-box component, still there is the oil circuit stringing that center tube etc. is independent, adopt integral type stringing lubrication system architecture form, the problem of the easy leakage of oil in tubing interface place still exists.
Summary of the invention
The object of this invention is to provide one and overcome the deficiencies in the prior art, solve the problem that stringing cost is high, gear-box is heavy, reduce the risk that lubrication system is revealed and reduced pressure, transmission system and lubrication system are combined, forms the lubrication system of real integral type.
This wind turbine gearbox lubrication system is applied to and is added in the wind turbine gearbox that the transmission of one-level parallel-axes gears forms by two-stage planet.Two-stage planet in gear-box adopts serial fashion, and it is secondary that wheel hub input power all flows through every one-level Gear Planet Transmission.Relate to the Lubrication Design of all gear engagement position of I and II Gear Planet Transmission and position of bearings.
Technological scheme of the present invention is that this lubrication system comprises shoe cream room, lubricating oil pipeline, and described first shoe cream room consists of mechanical seal case lid before primary planet carrier and gear; Described second shoe cream room is made up of one-level sun gear back shaft and primary planet carrier; Described 3rd shoe cream room is made up of one-level sun gear back shaft and secondary planet frame; Be connected by lubricating oil pipeline between shoe cream room, described grease channel is all arranged on the component of machine of gear-box.
Lubricant oil in lubricating oil bath, by gear-box mechanical pump/exterior electric pump, is pumped into the first shoe cream room by lubricating oil inlet by planet carrier.
Lubricant oil in first shoe cream room is divided into five branching part: first portion flow to the primary planet carrier bearing on primary planet carrier via the grease channel be arranged on primary planet carrier, this bearing is lubricated.Lubricant oil by and this bearing in the heat exchange of lubricating point, frictional heat is taken away, flow to oil back chamber by the grease channel on front case lid, in the oil sump during the lubrication channel on the premenstrual case lid of the lubricant oil in this oil back chamber flows in casing; Second portion flows into primary planet wheel/gear ring pipe arrangement by the grease channel on primary planet carrier, by being arranged on the nozzle on pipe arrangement, lubricant oil is injected in this point of mesh; Part III passes through-level planet carrier on grease channel flow into primary planet wheel/sun gear pipe arrangement, by being arranged on the nozzle on pipe arrangement, lubricant oil is injected in this point of mesh; Part IV flow to the second shoe cream room by the grease channel on primary planet carrier; Part V, by the grease channel on primary planet carrier, flows through the grease channel on primary planet flexible pin shaft, then the grease channel on primary planet wheel sleeve, flow to primary planet wheel bearing, to ensure the lubrication of this position of bearings.
One-level sun gear is supported by the sliding bearing on one-level sun gear back shaft, and the lubricant oil part flow in the second shoe cream room flow to this sliding bearing by the lubricating oil pipeline on one-level sun gear back shaft, ensures that it is lubricated.Remaining part is mainly used in the lubrication of second level Gear Planet Transmission.
-level sun gear back shaft and secondary planet frame form the 3rd shoe cream room.After lubricant oil flow to the 3rd shoe cream room by the lubricating oil pipeline on-level sun gear back shaft, flow mostly to three directions: first portion flow to secondary planet wheel/gear ring pipe arrangement by the grease channel be arranged on secondary planet frame, by being arranged on the nozzle on pipe arrangement, lubricant oil is injected in this point of mesh; Second portion flows into secondary planet wheel/sun gear pipe arrangement by the grease channel on secondary planet frame, by being arranged on the nozzle on pipe arrangement, lubricant oil is injected in this point of mesh; Part III, by the grease channel on secondary planet frame, flows through the grease channel on secondary planet flexible pin shaft, then the grease channel on secondary planet wheel sleeve, flow to secondary planet wheel bearing, ensures the lubrication of this position of bearings.
One-level, secondary planet wheel bearing, the lubricant oil of one-level, secondary planet driving gear contact points at the lubricant oil with lubricating point, is taken away heat, is revert to the oil sump in middle casing after heat exchange.Gear-box mechanical pump/exterior electric pump is by the lubricant oil sucking-off of oil sump, and by the heat exchanger of Pipeline transport to gear-box outside, again by the lubricant oil release heat wherein of heat exchanger, temperature is reduced, and then be pumped to the lubricating oil inlet of gear-box, thus form a circulating oil system of wind turbine gearbox.
All lubricating oil pipelines of the present invention are all arranged on the component such as planet carrier, casing and sun gear, form the lubrication system architecture of real integral type, eliminate the existence of the inner stringing separately of gear-box, decrease stringing cost, reduce gear-box weight, simultaneously because oil pocket is not be connected by pipe arrangement with each grease channel in lubrication system, but be directly communicated with, reduce the risk of leakage of oil.
