Description
Technical field
The present invention relates to a kind of casing of gear-box, more particularly to the upper box of wind turbine gearbox.
Background technology
With the fast development of wind generating technology, the transmission power of Wind turbines is increasing, to wind power speed-increasing gear
Case reliability and maintainability requires more and more higher, to reduce high transport, lifting and maintenance cost.Megawatt-level wind at present
Step-up gear typically adopts three-level step-up drive, is broadly divided into primary planet+two-stage parallel axis transmission and two-stage planet+one-level
The driving of parallel axes.Wherein again in the majority with the wind turbine gearbox using primary planet+two-stage parallel axis kind of drive.
In existing wind turbine gearbox, gearbox lubrication system passage typically adopts pipeline as lubrication channel, such as Fig. 1
Shown, this lubrication system architecture is a lot of due to pipe joint, and permeability is very risky, and the required precision to processing at pipe joint
Higher, otherwise easy seepage, therefore leads to the reliability of lubricating system to substantially reduce.According to wind field investigation, the feelings of pipe joint permeability
Condition happens occasionally, and blower fan safeguards that, due to needing to carry out in high-altitude, field maintenance person's lifting workload is big, dangerous high,
Oil leak, permeability situation should be avoided to occur as far as possible.
And the control to main screw lift with Wind turbines, cabin space is put forward higher requirement, therefore should use up
Amount simplifies the maintenance work of gear-box, reduces corner to be safeguarded as far as possible, makes gear-box be easy to safeguard.
Content of the invention
It is an object of the invention to provide one kind can improve wind turbine gearbox lubricating system reliability, reduce oil leak and ooze
Alopecia areata danger, the wind turbine gearbox upper box improving maintainability, reducing maintenance cost.
In order to achieve the above object, the technical scheme is that：A kind of wind turbine gearbox upper box, including upper box originally
Body, described upper box body has wind direction dead eye under low speed jackshaft, wind direction dead eye and high speed shaft under high speed jackshaft
Bearing saddle bore, equipped with high speed bearing housing in high speed shaft bearing saddle bore, equipped with the first oil pipe and the second oil pipe on upper box body,
First oil pipe import terminates on the oil path distributor of upper box bodies top, and outlet terminates at the high speed shaft axle of upper box body
By bearing hole, the second oil pipe import terminates on the oil path distributor of upper box bodies top, and outlet terminates at upper box body
Low speed jackshaft under at wind direction dead eye and lead to wind direction dead eye under low speed jackshaft, by high speed shaft bearing saddle bore
Upper box originally have the first oilhole, the second oilhole, the 3rd oilhole and the 4th oilhole, the described first oil pipe port of export and in vivo
One oilhole communicates, and the first oilhole is communicated with the second oilhole, and the second oilhole leads to upper box intrinsic second level parallel drive tooth
Wheel chamber, described first oilhole also communicated with the 3rd oilhole, and the 3rd oilhole leads to wind direction dead eye under high speed jackshaft, and described first
Oilhole is also communicated with the 4th oilhole, and the 4th oilhole leads to high speed bearing housing, the oil path distributor of described upper box bodies top
Inside also have the 5th oilhole.
Described first oilhole is parallel to the axially extended oilhole of high speed shaft bearing saddle bore axis, and described second oilhole is
The oilhole radially extending along high speed shaft bearing saddle bore, described 3rd oilhole is the oilhole of vertical extension, and described 4th oilhole is water
Put down to the oilhole extending, described 5th oilhole level is to the oilhole extending.
Described first oilhole also leads to upper box intrinsic third level parallel drive gear cavity.
After said structure, due to the wind turbine gearbox upper box of the present invention adopt the first oilhole of box house, the
Two oilholes, the 3rd oilhole, the 4th oilhole and the 5th oilhole, only with the first oil pipe and two external oil pipes of the second oil pipe, relatively
For the multiple-tubing string, multiple pipe joint of prior art, oil leak and permeability risk substantially reduce, and wind turbine gearbox reliability carries
High；Due also to external oil pipe quantity is few, so pipeline maintainability provides significantly, substantially non-maintaining, make tieing up of wind turbine gearbox
Shield property greatly improves, and maintenance cost is greatly reduced；Additionally, making the lubricating system assembling of wind turbine gearbox significantly simplify, assembling effect
Rate is greatly improved；Transport Safety and the hoisting safety of gear-box again because external oil pipe quantity is few, are greatly improved, significantly drop
Low transport and the risk of lifting.
