Abstract
The invention relates to a bearing chamber structure, which comprises a bearing retainer ring, a bearing outer cover and an oil scraping tube, wherein the bearing retainer ring is arranged between a bearing and the bearing outer cover for axial bearing fixing; the contact end between the bearing retainer ring and the bearing is a cylindrical section; the other section, located in the bearing outer cover, of the bearing retainer ring is a cam section; a through hole is arranged in the bearing outer cover along the radial direction; the oil scraping tube is a through tube whose front end is provided with an elastic scraping sheet; the oil scraping tube is placed in the through hole of the bearing outer cover; and the elastic scraping sheet at the front end of the oil scraping tube is contacted with the cam section of the bearing retainer ring. The bearing retainer ring located inside the bearing outer cover is set to be a cam section, the oil scraping tube only needs to be placed in the through hole of the bearing outer cover, a rotating shaft is rotated, and a cavity whose volume can be reduced is formed among the bearing retainer ring, the bearing outer cover and the elastic scraping sheet at the front end of the oil scraping tube. Most waste oils and fats are thus squeezed to enter the oil scraping tube. The entire waste oil cleaning process is excessively convenient and simple.
Description
Technical field
The present invention relates to a kind of bearing chamber structure.
Background technology
It is not freely the too high a kind of reason of motor bearings temperature rise that waste oil is discharged, also need to extract grease in bearing chamber to analyze when checking motor, when safeguarding, often need with manual demolition enclosing cover, the unnecessary waste oil at cleaning enclosing cover place, particularly the non-end bearing of stretching of wind-driven generator is safeguarded, need to remove the parts such as air duct, carbon brush slip-ring, encoder, winding connection, lower bearing enclosing cover could be unloaded and carry out relevant operation, workload is large, destructible wiring is insulated, and when reassembling, assembled in situ precision is inadequate, may affect the follow-up normal operation of motor.
Summary of the invention
A kind of structure is the object of the present invention is to provide simply to clear up waste oil bearing chamber structure easily.
Technical scheme of the present invention is, a kind of bearing chamber structure, it comprises end ring, bearing end cover and scrapes oil pipe, described end ring is arranged on the axial restraint for bearing between bearing and bearing end cover, described end ring and bearing touch end are cylindrical section, another section that described end ring is positioned at bearing end cover is cam segment, described bearing end cover is radially provided with through hole, described oil pipe of scraping is the siphunculus that front end is provided with elastic doctor blade, scraping oil pipe is placed in the through hole of bearing end cover, and the cam segment of the elastic doctor blade and end ring of scraping oil pipe front end contacts.
Preferably, the cam segment of described end ring is centrally symmetrically arranged with two cams.
Preferably, described bearing end cover through hole is radially square opening, described in scrape oil pipe be the square siphunculus that front portion is provided with elastic doctor blade.
Advantageous Effects of the present invention is, due to the end ring being positioned at bearing end cover is arranged to cam segment, when needs cleaning excessive fuel consumption, only need be placed in the through hole of bearing end cover by scraping oil pipe, rotating shaft, the cam segment of the elastic doctor blade and end ring of scraping oil pipe front end contacts, end ring, bearing end cover and scrape between the elastic doctor blade of oil pipe front end formed a reducible chamber of volume.Therefore most of waste oil is pressed into scrapes in oil pipe pipe.Oil pipe is scraped in taking-up, completes oil extraction.Whole waste oil scale removal process is very easy.

Fig. 2 embodiment of the present invention structural representation;
Fig. 3 embodiment of the present invention end ring structural representation.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to accompanying drawing, a kind of bearing chamber structure, it comprises end ring 5, bearing end cover 6 and scrape oil pipe 7, inner cap 2 is provided with inside the end cap 3 of machine shaft 1 end, bearing 4 is arranged on end cap 3 inner circle, described end ring 5 is arranged on the axial restraint for bearing 4 between bearing 4 and bearing end cover 6, described end ring 5 is cylindrical section 5-2 with bearing 4 contact jaw, another section that described end ring 5 is positioned at bearing end cover 6 is cam segment 5-1, the cam segment 5-1 of described end ring 5 is centrally symmetrically arranged with two cams, described bearing end cover 6 is radially provided with square through hole 6-1, describedly scrape oil pipe 7 for front end and be provided with the square siphunculus of elastic doctor blade 7-1, scraping oil pipe 7 is placed in the square through hole 6-1 of bearing end cover 6, the cam segment 5-1 of the elastic doctor blade 7-1 and end ring 5 that scrape oil pipe 7 front end contacts.
When waste oil is full of bearing chamber, when needing to safeguard, oil pipe 7 will be scraped insert from square through hole 6-1, until scrape the cam segment 5-1 of oil pipe 7 front end elastic doctor blade 7-1 contact bearing back-up ring 5, allow machine shaft 1 slow circumvolve, then end ring 5 rotates thereupon, end ring 5, bearing end cover 6 and scrape between the elastic doctor blade 7-1 of oil pipe 7 front end formed a reducible chamber of volume, most of waste oil be therefore pressed into scrape oil pipe 7 rear end square tube in, oil pipe 7 is scraped in taking-up, complete oil extraction, after having blocked square through hole 6-1, open motor and normally run.
