Abstract
The present invention relates to a kind of bearing chamber structure, it includes end ring, bearing end cover and scrapes oil pipe, the end ring is arranged on the axial restraint for being used for bearing between bearing and bearing end cover, the end ring and bearing touch end are cylindrical section, the end ring be located in bearing end cover another section is cam segment, the bearing end cover is radially provided with through hole, the siphunculus scraped oil pipe and elastic doctor blade is provided with for front end, scrape oil pipe to be placed in the through hole of bearing end cover, scrape the elastic doctor blade of oil pipe front end and contacted with the cam segment of end ring.The present invention only need to will scrape oil pipe and be placed in the through hole of bearing end cover due to the end ring in bearing end cover is arranged into cam segment, rotating shaft, in end ring, bearing end cover and scrape and form a reducible chamber of volume between the elastic doctor blade of oil pipe front end.Therefore most of waste oils are pressed into and scraped in oil pipe pipe.Whole waste oil scale removal process is very easy.
Description
Technical field
The present invention relates to a kind of bearing chamber structure.
Background technology
Waste oil discharge is not freely a kind of too high reason of motor bearings temperature rise, is also required to take out when checking motor
Take grease in bearing chamber to be analyzed, when being safeguarded, generally require with manual demolition enclosing cover, clear up unnecessary useless at enclosing cover
The non-end bearing of stretching of grease, particularly wind-driven generator is safeguarded, it is necessary to remove the portions such as air duct, carbon brush slip-ring, encoder, winding connection
Part, lower bearing enclosing cover could be unloaded and carry out related operation, workload is big, destructible wiring insulation, and assembled in situ essence when reassembling
Degree is inadequate, may influence motor and subsequently run well.
The content of the invention
It is an object of the invention to provide a kind of cleaning convenient bearing chamber structure of waste oil simple in construction.
The technical scheme is that a kind of bearing chamber structure, it includes end ring, bearing end cover and scrapes oil pipe, institute
State end ring and be arranged on the axial restraint for being used for bearing between bearing and bearing end cover, the end ring and bearing touch end
For cylindrical section, the end ring be located in bearing end cover another section is cam segment, and the bearing end cover is radially provided with logical
Hole, the siphunculus scraped oil pipe and elastic doctor blade is provided with for front end, scrapes oil pipe and is placed in the through hole of bearing end cover, scrape oil pipe front end
Elastic doctor blade contacts with the cam segment of end ring.
Preferably, the cam segment of the end ring has two cams along center symmetric setting.
Preferably, the through hole of the bearing end cover radially is square opening, and the oil pipe of scraping is provided with elastic doctor blade for front portion
Square siphunculus.
The method have the benefit that due to the end ring in bearing end cover is arranged into cam segment, when
When needing to clear up excessive fuel consumption, only it need to will scrape oil pipe and be placed in the through hole of bearing end cover, rotating shaft, scrape the elastic doctor blade of oil pipe front end
Contacted with the cam segment of end ring, in end ring, bearing end cover and scrape an appearance is formed between the elastic doctor blade of oil pipe front end
The reducible chamber of product.Therefore most of waste oils are pressed into and scraped in oil pipe pipe.Oil pipe is scraped in taking-up, completes oil extraction.Entirely
Waste oil scale removal process is very easy.
Brief description of the drawings
Fig. 1 structural decomposition diagrams of the embodiment of the present invention；
Fig. 2 structural representations of the embodiment of the present invention；
Fig. 3 end ring structural representations of the embodiment of the present invention.
Embodiment
Below in conjunction with drawings and examples, the invention will be further described.
Referring to the drawings, a kind of bearing chamber structure, it includes end ring 5, bearing end cover 6 and scrapes oil pipe 7, in machine shaft
The inner side of end cap 3 of 1 end is provided with inner cap 2, and bearing 4 is arranged on the inner circle of end cap 3, and the end ring 5 is arranged on bearing 4 and axle
Hold the axial restraint for being used for bearing 4 between enclosing cover 6, the end ring 5 and the contact jaw of bearing 4 are cylindrical section 5-2, the bearing
Back-up ring 5 is located at another section in bearing end cover 6 and set for cam segment 5-1, the cam segment 5-1 of the end ring 5 along Central Symmetry
Two cams are equipped with, the bearing end cover 6 is radially provided with square through hole 6-1, and the oil pipe 7 of scraping is provided with elastic doctor blade for front end
7-1 square siphunculus, scrape oil pipe 7 and be placed in the square through hole 6-1 of bearing end cover 6, scrape the elastic doctor blade 7-1 of the front end of oil pipe 7 with
The cam segment 5-1 contacts of end ring 5.
When waste oil full of bearing chamber, it is necessary to when safeguarding, oil pipe 7 will be scraped and inserted from square through hole 6-1, until scrape oil pipe
The cam segment 5-1 of 7 front end elastic doctor blade 7-1 contact bearings back-up rings 5, allows machine shaft 1 slowly to rotate, then end ring 5 is therewith
Rotation, in end ring 5, bearing end cover 6 and scrape a reducible chamber of volume is formed between the front end elastic doctor blade 7-1 of oil pipe 7
Therefore room, most of waste oils are pressed into the square tube for scraping the rear end of oil pipe 7, oil pipe 7 is scraped in taking-up, are completed oil extraction, are blocked
After square through hole 6-1, motor normal operation is opened.
