Description
Technical field
This utility model is related to wind turbine gearbox, and more particularly to a kind of wind turbine gearbox lubrication uses pipe axle.
Background technology
Wind turbine gearbox now typically forces profit using external oil pipe or internal oil pipe for two side bearing of pipe axle
Sliding, there is the risk of oil leak in this structure lubricated using pipeline.Particularly exterior line, during gear-box handling easily
Collision, causes to deform, and aggravates oil leak risk；Planet wheel bearing due to being in rotation status, and generally lubricant passage way be fixed,
This needs to be sprayed onto on the planet wheel bearing of rotation lubricating oil by fixed pipeline.At present generally using fixed lubrication, oil sump
Lubrication and the mode of rotary lubrication, fixed lubrication is lubricated to planet wheel bearing using fixed pipeline, due to planetary gear
In rotation, fixed lubrication cannot meet the lubrication of planet wheel bearing constantly;Oil sump lubricates the cleannes and temperature to lubricating oil
Control requires higher;What this patent was proposed is rotary lubrication mode, and gear ring is typically using external oil pipe or internal oil pipe pressure
Lubrication, but generally only the top position of gear ring is lubricated；Gear ring bottom uses oil sump lubrication；And planetary gear and gear ring
Engagement be present in gear ring institute with teeth, about 2/3 region of such gear ring can not be always maintained at forced feed lubrication;Sun gear is because being in tooth
Roller box center, and rotation status, usually not forced feed lubrication oil circuit are kept, can only be attached in the oil sump of part by planetary gear
Lubricating oil be lubricated, few to sun gear lubricants capacity the fact that usual and extremely difficult control.
Utility model content
This utility model purpose is to provide a kind of wind turbine gearbox lubrication pipe axle to overcome the deficiencies in the prior art,
Realize for gearbox oil-channel being changed to built-in structure for coordinating, it is to avoid the relevant issues such as external oil pipe rapid wear.
Above-mentioned purpose is reached, a kind of technical scheme that this utility model is taken is：A kind of wind turbine gearbox lubrication uses pipe axle,
Including pipe shaft body and being sheathed on pipe box on pipe axle；The circumferential end surfaces of described pipe shaft body one end are provided with axial direction " type fuel feed hole,
The pipe shaft body other end is provided with axial Г types oil-out；Forming one between the pipe box and the pipe shaft body is used for lubricating
The annular oil cavity that oil passes through；Described " oil-out end and the annular oil cavity of type fuel feed hole be connected, the Г types oil-out
Oil-in end be connected with the annular oil cavity.
Further improved as this utility model, the pipe box is located at the pipe shaft body " type fuel feed hole connection end
It is tightly connected by sealing structure I, the pipe box passes through sealing structure II with the connection end of the pipe shaft body Г type oil-out
It is tightly connected.
Further improved as this utility model, the pipe box circumferential inner wall is all provided with the pipe shaft body outer circumferential walls
There is anticorrosion antiwear layer.
Due to the utilization of above-mentioned technical proposal, this utility model has following advantages compared with prior art：By pipe axle
Structure design, from wind turbine gearbox transparent cover flow into lubricating oil by pipe shaft body oil-in end enter annular oil cavity pass through again
The oil-out end of pipe shaft body flows to the flange of wind turbine gearbox, has efficiently accomplished change of the oil circuit from static element to revolving part；
Oil channel structures in gear-box are simplified, the fuel feeding requirement of planetary stage gear, bearing is met；Avoid during handling gear-box because
Collision causes external oil pipe to deform, and reduces the risk of oil leak.

Below in conjunction with the accompanying drawings technical solutions of the utility model are described further：
Accompanying drawing 1 is a kind of wind turbine gearbox lubrication pipe axle construction schematic diagram of the present utility model；
Accompanying drawing 2 is sealing structure I partial enlargement structural representation；
Accompanying drawing 3 is sealing structure II partial enlargement structural representation.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment detailed description that this utility model is made.
Described in the utility model as shown in accompanying drawing 1,2,3 takes a kind of wind turbine gearbox lubrication pipe axle construction schematic diagram
In, pipe axle 001 includes pipe shaft body 1 and is sheathed on pipe box 2 on pipe axle；The circumferential end surfaces of 1 one end of pipe shaft body are provided with axial direction "
Type fuel feed hole 3,1 other end of pipe shaft body are provided with axial Г types oil-out 4；Forming one between pipe box 2 and pipe shaft body 1 is used for moistening
The annular oil cavity 5 that lubricating oil passes through；" oil-out end and the annular oil cavity 5 of type fuel feed hole 3 be connected, the oil-feed of Г types oil-out 4
Mouth end is connected with annular oil cavity 5；Pipe box 2 is located at pipe shaft body 1 " 3 connection end of type fuel feed hole by sealing structure I 6 close
Envelope connection, sealing structure I 6 can be to oil pocket 5 by the O-ring seal 8 of pipe box 2 and pipe shaft body connection end contact surface groove
Middle lubricating oil carries out first sealing, by the roughness of 1 junction of roughness and pipe shaft body of 2 its right end face of control sleeve
And the control of form and position tolerance carries out end surface mechanical sealing, to carrying out second sealing by a small amount of lubricating oil of first sealing；
Pipe box 2 is tightly connected by sealing structure II 7 with the connection end of 1 Г types oil-out 4 of pipe shaft body, and sealing structure II 7 passes through
Pipe box 2 can carry out first sealing to lubricating oil in oil pocket with the O-ring seal 9 of 1 connection end contact surface groove of pipe box body,
The control of locating groove roughness and form and position tolerance is provided with by the roughness and pipe shaft body of 2 left end face of control sleeve,
The control for being provided with 10 roughness of back-up ring for positioning pipe sleeve 2 in draw-in groove carries out end surface mechanical sealing, to being sealed by first
A small amount of lubricating oil carry out second sealing；2 circumferential inner wall of pipe box is equipped with anticorrosion antiwear layer with 1 outer circumferential walls of pipe shaft body
（Not shown in figure）；By the structure design of pipe axle, the lubricating oil flowed into from wind turbine gearbox transparent cover passes through pipe shaft body oil-feed
Mouthful end enters annular oil cavity and flows to the flange of wind turbine gearbox by the oil-out end of pipe shaft body again, efficiently accomplished oil circuit from
Change of the static element to revolving part；Oil channel structures in gear-box are simplified, the fuel feeding requirement of planetary stage gear, bearing is met；Keep away
Exempt from gear-box during handling and, because collision causes external oil pipe to deform, reduce the risk of oil leak.
