The utility model discloses can realize the leak protection oil of gear rear end bearing portion, can realize the stirring circulation of grease again, make it fully participate in gear engagement.
Description
Technical field
The utility model relates to gear lubrication and oil-leakage-prevention technology.
Background technique
The project organization of electric tool is compact, and the five internal organs are various; As the core transmission component-gear of machine; Running up, lower lubricant grease highlights its significance, but conventional tool lubricant grease easily spills or is subject to the poor fluidity of the restriction grease of cost, thus grease can not be good lubricating transmission parts gear, make gear under High Rotation Speed, serious wear, skid, the life-span is short, cause the decline of machine life; Therefore leakproof oil and grease keeps fully active participation gears meshing to be a very important problem.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of lubricant grease circulation oil leakage preventing apparatus and electric tool, can oil-leakage-prevention, can realize again the agitation cycle of lubricant grease, make lubricant grease fully participate in gears meshing.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of lubricant grease circulation oil leakage preventing apparatus, comprise head capsule, adjacent bearing chamber and gear chamber is provided with in head capsule, described bearing chamber be provided with the endoporus be communicated with between gear chamber, one transmission shaft is successively through bearing chamber, endoporus and gear chamber, described transmission shaft is provided with bearing in bearing chamber, described transmission shaft is provided with gear in gear chamber, the rear end of described gear is provided with grease circulation seal ring, the rear end of described grease circulation seal ring is provided with sealing configuration, the front end of described grease circulation seal ring is provided with agitation cycle structure.
Realized the oil-leakage-prevention of bearing portion by screw seal structure, realized the agitation cycle of grease by agitation cycle structure.
Preferably, described agitation cycle structure is the flabellum around the distribution of grease circulation seal ring circumference.
The lubricant grease near gear place deposition in gear chamber can be stirred by simple blade structure, driven forward and Inner eycle, make its oilgear engaging position.
Further, described flabellum is tilted to the sense of rotation of grease circulation seal ring by the rear side of grease circulation seal ring.Promotion grease stirs, and improves flabellum to the mixing effect of lubricant grease.
Further, described flabellum diamond shaped.Optimize flabellum to the mixing effect of lubricant grease.
Preferably, described sealing configuration is spiral seal face.Spiral seal face and endoporus form bearing position leak-proof arrangement, are fed forward by oil spill fat.
Further, described spiral seal face is axially arranged with at least two circles along grease circulation seal ring.By the quantitative commitments oil-leakage-prevention effect in spiral seal face.
Further, the rear end of described gear is circumferentially provided with positioning step anchor ring, and described grease circulation seal ring close-fitting is fixed on positioning step anchor ring.Realize the accurate installation of grease circulation seal ring, pinion rotation just can drive grease circulation seal ring to rotate together.
The utility model additionally provides a kind of electric tool, and it is provided with above-mentioned lubricant grease circulation oil leakage preventing apparatus.
The utility model structure is simple, and wherein, spiral seal face and endoporus form bearing position leak-proof arrangement, agitation cycle structure realizes the agitation cycle of grease, therefore can realize the oil-leakage-prevention at gear rear end bearing position, the agitation cycle of grease can be realized again, make it fully participate in gears meshing; " one attacks one prevents " the two-in-one life-span at utmost ensureing gear-box.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the partial structurtes schematic diagram of electric tool;
Fig. 2 is the front-end architecture schematic diagram of grease circulation seal ring;
Fig. 3 is the rear end structure schematic diagram of grease circulation seal ring;
Fig. 4 is the cross-sectional view of grease circulation seal ring.
Embodiment
As shown in Figures 1 to 4, to be used on electric tool, illustrate lubricant grease circulation oil leakage preventing apparatus, it comprises head capsule 1, adjacent bearing chamber and gear chamber is provided with in head capsule 1, described bearing chamber be provided with the endoporus 111 be communicated with between gear chamber, one transmission shaft 11 is successively through bearing chamber, endoporus and gear chamber, described transmission shaft 11 is provided with bearing 13 in bearing chamber, described transmission shaft 11 is provided with gear 12 in gear chamber, the rear end of described gear 12 is provided with grease circulation seal ring 2, the rear end of described grease circulation seal ring 2 is provided with sealing configuration 22, the front end of described grease circulation seal ring 2 is provided with agitation cycle structure 21.
Agitation cycle structure on grease circulation seal ring is together with sealing and anti-leakage oil textural association, and the gear jointly making gear chamber inner high speed rotate is at every moment lubricated, thus further extends service life of a machine.
Wherein, the rear end of gear 12 is circumferentially provided with positioning step anchor ring 121, and described grease circulation seal ring 2 close-fitting is fixed on positioning step anchor ring 121, and it realizes fixing by interference fit, and gear 12 rotates and grease circulation seal ring 2 just can be driven to rotate together.
As shown in Figure 2, described agitation cycle structure 21 is the flabellum around the distribution of grease circulation seal ring circumference.Described flabellum is tilted to the sense of rotation of grease circulation seal ring by the rear side of grease circulation seal ring.Described flabellum diamond shaped.Due to grease circulation seal ring front end comparatively large end face and blade structure, under pinion rotation drives, make the lubricant grease of gear chamber inside deposition be pushed at gear chamber Inner eycle, effectively lubricating is carried out to gear.
As shown in Figure 3, sealing configuration 22 is spiral seal face, and spiral seal face is axially arranged with at least two circles along grease circulation seal ring.Further, the diameter in spiral seal face is progressively increased by rear end forward end diameter.This spiral seal face and endoporus 111 form bearing position leak-proof arrangement, similar worm screw principle, there is the effect of driven forward lubricant grease and oil-leakage-prevention, make lubricant grease stay in gear chamber, avoid the key components and parts caused because of gear chamber leakage of oil and damage and cause machine failure.
