Description
Technical field
This utility model relates to technical field of wind power, particularly relates to a kind of separate type wind-driven generator group wheel box casing.
Background technology
Wind-driven generator group wheel box is a kind of step-up gear, rises in the Wind turbines using middle and high speed generator
Transmission moment of torsion and increase the effect of rotating speed.Wind-driven generator group wheel box is used for preventing friction, extending tooth built with lubricating oil
The wheel life-span, but lubricating oil is typically after using 3-5, and it is heavy that the inside just has gear meshing wear granule, oil ageing is decomposed
Shallow lake thing and other pollutant, although lubricating oil through supercooling circulating filtration, but still can have more wear particle and precipitate to sink
Amass at the bottom of gear-box, remove the most difficult.Even if it is not the gear box lubricating oil more renewed, thorough because clearing up bottom gear-box, with
The operating of gear-box, new oil is constantly overturn stirring, makes the deposit of bottom constantly be blended in lubricating oil, Jin Erjin
Enter meshing zone of gears territory, thus strengthen abrasion and the lubricant pollution of gear-box, cause the pollution in advance of gear case oil aging and
Reduce the service life of gear-box.
Lubricating oil has the effect cleaning gear-box.Gear-box is when long-distance sea, land transportation, for avoiding inside gear-box
Component corrosion and damage, can place jury preservative, antirust agent in gear-box, before gear-box uses, and be by gear
Anticorrosion, antirust agent in case all empty, and are then shut off draining valve, from the fuel feed hole at gear-box top (or gear-box air
Filter hole or casing observation port) add gear box lubricating oil be rinsed, then empty, complete the cleaning of gear-box.
If not washing clean clearly, will result in the pollution of lubricating oil and reducing the service life of gear-box.The longevity is used when lubricating oil arrives
Needing during life to change in time, the method for the most more oil change is that suitable position arranges outage, oil extraction bottom gear-box
Valve and oil pump, thus substantially emptied by the lubricating oil in gear-box, there is gear-box oil extraction thoroughly and tooth in this method of discharge
Roller box cleans sordid problem, thus causes reduce the service life of gear-box and lubricating oil.
Gear drive is one of kind of drive the most commonly used in plant equipment.Wind turbine gearbox running status normal with
The no working condition being directly connected to whole unit.According to relevant statistics, gear-box break down 40% reason be by
In designing, manufacture, assemble and the factor such as raw material causing, i.e. manufactured and designed by manufacturer and cause；Separately have 43%
Reason causes with misoperation not in time owing to user safeguards；Also have 17% reason be due to neighbor (as motor,
Shaft coupling etc.) fault or defect cause.Certainly, whether wind turbine gearbox failure cause has this proportionate relationship, also to pass through
Statistics draws.As can be seen here, in order to ensure wind turbine gearbox safety, normally run, improve gear-driven reliability, a side
Face needs Curve guide impeller, improves processing and manufacturing precision and improve assembling quality, on the other hand then must improve operational management and
Maintenance levels, carries out condition monitoring and fault diagnosis to gear drive.And typically gear drive carries out status monitoring
It is difficult to there is a good maintenance result with fault diagnosis.
Summary of the invention
The problem that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist, it is provided that a kind of separate type wind-force
Generating set gear case body so that box bottom separates with casing, it is possible to resolve the not thorough problem of gear-box cleaning, is greatly improved
Gear-box and Working Life of Lubricating Oil, be unlikely to 3 to five years just to change；Additionally, separating box, more there is the inspection utilizing fault
Repair and detect.
The technical solution adopted in the utility model is as follows: a kind of separate type wind-driven generator group wheel box casing, including case
Body, it is characterised in that: casing is divided into upper and lower two parts, and top is divided into casing cover, and bottom is divided into one piece of base plate, it is characterised in that:
Casing cover and base plate are tightly connected.
Four edges of box body wall of casing cover lower part described in the utility model are respectively equipped with a horizontal folding plate；Base plate four
Individual edge four limit is provided with vertical box body wall, and four edges of vertical box body wall are respectively equipped with a horizontal folding plate.
Horizontal folding plate on casing cover described in the utility model and the horizontal folding plate on base plate are equal in magnitude, on the two
End is respectively arranged with screw hole, and screw hole is fixed by sealing bolt.
Horizontal folding plate on casing cover described in the utility model and the horizontal folding plate mid layer section on base plate are provided with
Seal washer, seal washer is shaped as ring-shaped, and its size is identical with the horizontal folding plate on casing cover so that it is box body tightness
It is greatly reinforced.
Casing described in the utility model is covered with fuel feed hole, is provided with draining valve on base plate.
After horizontal folding plate on casing cover described in the utility model and the horizontal folding plate on base plate are tightly connected, also
Carry out bound edge process, it is ensured that sealing.
Draining valve described in the utility model is arranged in the middle of base plate, and box bottom has certain angle of inclination, and gradually
Shrinking to draining valve position, casing internal contamination granule and precipitate are concentrated and are tilted to box bottom low level, are discharged by draining valve.
Base plate described in the utility model carries out grinding process, and whole tank surface inwall is coated with antiseep enamelled coating, main
Lubricant pollution granule to be and precipitate are difficult to stop in its tank surface, concentrate on base plate, then regularly replace the end
Plate, reaches thoroughly to clean gear-box problem.
The utility model has the advantages that: first wind-driven generator group wheel box casing is separated into two by this utility model
Point, main thought is that the day-to-day operation maintenance content of wind-driven generator group wheel box specifically includes that equipment appearance inspection, noise
Test, oil level inspection, oil temperature, electrical wiring inspection etc..Its mode, for checking gear-box oil level, checks gear pump wiring, casing
And lubricating pipe is with or without Seepage, the lubricating pipe of peripheral hardware has non-loosening, cleans gear-box, utilizes oil scale or oil level sight window inspection
Look into oil level the most normal, observe oil colours by glass oil window the most normal, find that oil level is on the low side and should supplement in time and search specifically
Breakthrough, processes in time and checks whether filter element has iron filings and thoroughly clean inside；Shortcoming is that detection elapsed time is oversize, typically
The detection overall process completing a sample needs two to five days time；Testing result is accurate, but in fact in status monitoring more
Focus on is the precision of trend rather than data；Part detecting instrument is expensive, bulky, is not suitable for pushing away in enterprise's one-level
Wide use and large area；Can greatly reduce the repair time after casing is separated into two parts, above-mentioned maintenance also ratio is before
Simpler and simplify；It is furthermore possible to solve the not thorough problem of gear-box cleaning, improves gear-box and Working Life of Lubricating Oil；This wind
Power generator group gear box structure is simple, easy installation and removal, cleans thoroughly.
