Description
Technical field
The present invention relates to gear-box maintenance technique field more particularly to a kind of wind turbine gearbox output shaft housing bearing position are empty
Restorative procedure.
Background technique
The wind-driven generator wheel-box of existing high-power type generally uses gear for two stage planetary gear train and final stage parallel speed increasing
The structure of grade, belongs to large gearbox, and overall weight is generally at 30 tons or more, and the weight of the input planet carrier of high-power type
Amount just reaches several tons, assembles relatively difficult, since gear-box is due to design and process are medium, leads to bearing position magnitude of interference mistake
It is small；Furthermore due to gear-box, especially wind turbine gearbox, special running environment factor often has the use such as overload, unbalance loading
Operating condition；These reasons are easy to that gearbox shaft bearing outer-ring is made to run circle, and bearing position abrasion size is caused to transfinite；When outside box bearing
When circle runs circle, the service life for reducing gear-box can be accelerated；Once it breaks down, at present generally can not be in high-altitude maintenance, it can only
Integral replacing causes the use cost of the wind-driven generator of high-power type high.
Summary of the invention
The present invention is to solve the above problems, provide a kind of wind turbine gearbox output shaft housing bearing position sky restorative procedure.
The technical solution used in the present invention:
A kind of wind turbine gearbox output shaft housing bearing position sky restorative procedure, the steps include:
1) it selects and is replaced with the comparable bearing of original gear case output shaft bearing capacity first；
2) the bearing wear region of gear box casing is cleaned up with cleaning agent, then inlays alloyage material sleeve, sleeve
Outer diameter is singly matched according to housing bore actual size, using interference fit between sleeve outer diameter and shell, is installed by heating method；
It is fixed between sleeve and gear box casing with pin, prevents circumference from rotating；Gluing and interference between sleeve inner ring and bearing outer ring
Cooperation；
3) bearing inner race change in size need to change baffle fit face size, avoid interfering；Bearing designation change gear
Plate outer diameter needs to change, and baffle is interfered with bearing roller when output shaft being avoided to install；
4) in order to guarantee the bearing roller of new bearing and the lateral clearance and bearing width change in size of bearing inner race 2mm,
Front bearing, output shaft position shoulder block and bearing inner race increase spacer ring；
5) internal diameter for replacing new model bearing changes, and output shaft diameter of axle needs, which are done over again, adapts to bearing bore diameter.
The cleaning agent is Jon Tarrant EC-00.
The alloy material of the sleeve is steel material.
Gluing between the sleeve inner ring and bearing outer ring is happy Thailand 640.
Using interference fit, magnitude of interference 0.03-0.05mm between the sleeve outer diameter and gear box casing.
Beneficial effects of the present invention: the present invention realizes that re-manufacturing technology is applied in wind power gear tank shell output shaft bearing position
Reparation, remanufacture quality not less than even higher than original product, in-flight maintenance can shorten maintenance cycle, which more saves
About material, the energy and cost, economic benefit is very high,.
