Background technique
Retarder generally adopts Lubricant on Gear to carry out lubrication and cooling, lubricant oil in reducer shell too much easily causes oil leakage, the very few lubrication effect that easily causes again is poor, therefore in retarder the point of addition of lubricant oil generally at 1/1 to two/3rd of gear Lower Half, and gears meshing position is the tooth in the middle part of gear, and the lubricant level in reducer shell is lower than engaging tooth, therefore gear lubrication is by getting rid of the lubricant oil fallen down to eminence during pinion rotation in the course of the work, namely existing reducer gear lubrication is the mode adopting splash lubrication, gear lubrication effect is poor.
The gear applied in prior art in retarder does not have shock-damping structure, retarder in the course of the work, because the engagement between gear exists impact, make noise during gears meshing comparatively large, and the collision taking turns between cog also can cause gear to occur the problem ruptured.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of gear with damping and oil-collecting lubricating function, do not have shock-damping structure to solve gear of the prior art, there is impact during gears meshing between gear, when making gears meshing easily there is the problem of fracture in the comparatively large and gear teeth of noise; And retarder middle gear adopts the mode of splash lubrication to there is gear lubrication and the poor technical problem of cooling effect in solution prior art.
The gear of the damping of the utility model band and oil-collecting lubricating function, comprise inner ring body and outer ring body, the external cylindrical surface of described outer ring body is provided with the gear teeth, the inner cylindrical surface of described outer ring body is evenly arranged groove, the external cylindrical surface of described inner ring body is provided with lobe, described lobe is arranged in groove, and is provided with snubber block in the circumferential gap of lobe and groove;
Also comprise the oil catcher be arranged on outer ring body, described oil catcher comprises the annulus body be fixed on gear mass end face, evenly dividing plate is provided with in described annulus body, independently shoe cream room is formed between adjacent separator, teeth groove one_to_one corresponding on described shoe cream room and gear mass, the inner ring surface of described annulus body is provided with the oil inlet hole be communicated with shoe cream room, the side that described annulus body coordinates with gear mass end face is provided with oil outlet.
Further, the end face of described inner ring body is connected by screw the baffle plate preventing outer ring body from coming off vertically.
Further, described inner ring body and outer ring body are made up of powder metallurgy.
Further, described snubber block is polyurethane snubber block.
Further, described oil outlet is near the outer ring surface of annulus body.
Further, described oil catcher is connected with gear mass by screw.
Further, the cross section of described annulus body is rectangle.
The beneficial effects of the utility model:
1, the gear of the damping of the utility model band and oil-collecting lubricating function, it by arranging snubber block between inner ring body and outer ring body, when gears meshing, gear is subject to impulsive load by gear, and now outer ring body just can to snubber block applying pressure along the circumferential direction, snubber block generation resiliently deformable, apparatus with shock absorbing, realizes gear damping, can reduce noise during gears meshing, and can avoid impacting the injury to the gear teeth, avoid occurring broken teeth problem.
2, the gear of the damping of the utility model band and oil-collecting lubricating function, it by arranging oil catcher on gear mass end face, during work, in oil catcher, annulus body is immersed in lubricant oil a section of gear bottom, lubricant oil enters shoe cream room through oil inlet hole, pinion rotation followed by lubricant oil in shoe cream room, make parts of lubricating oil can be taken to meshing zone of gears to lubricate gear, thus the lubrication and cooling effect of gear can be improved, extend the working life of gear.
