Description
Technical field
The utility model belongs to technical field of sealing technology, particularly relates to a kind of output shaft of gear-box oil sealing.
Background technology
Oil sealing is the custom appellation of general seal, is exactly briefly the sealing of lubricating oil. Oil sealing is the mechanical organ for oil sealing (oil is modal liquid substance in transmission system, also makes a general reference the meaning of general liquid substance), it will in drive disk assembly, need lubricated parts and the parts isolation of exerting oneself, be unlikely to allow oil seepage. Commonly use bearing place, particularly rolling bearing position with various machineries.
Along with internationalization cooperation is progressively moved towards in production and the exploitation of automobile, the quality of automobile gearbox is just towards future developments such as low pollution, low energy consumption, high output, high efficiency, high reliability, and meanwhile the leakage problems of gearbox also more and more causes the attention of user vehicle and manufacturer; Therefore one of key factor of gearbox quality improves in the permanently effective sealing Shi Ge gearbox enterprise that, ensures oil sealing. But the bearing seal of gearbox is different from other bearing seal, its sealing operating mode is very complicated, as larger in the bias of bearing, rotating speed is higher, and service time is longer continuously, add domestic road conditions complexity, environment is severe, and the durability of gearbox oil sealing has been proposed to very large test.
Number of patent application CN201420331402.5 has announced a kind of output shaft of gear-box oil sealing, comprise metallic framework and outside sheathed rubber skeleton thereof, the bottom of rubber skeleton is provided with the main lip of sealing, sealing two-pack lip, on rubber skeleton, a side of nearly sealing two-pack lip is provided with nonwoven dust ring, dust ring is fixedly connected with rubber skeleton by adhesive sheet, seal on main lip and be provided with multiple dentation projections away from a side of sealing two-pack lip, the inner side that seals main lip offers the groove matching with spring, the inwall of this groove is provided with projection with the junction of the medial surface of the main lip of sealing, the lip of sealing two-pack lip is arcuate structure, spring is hollow spring. this utility model adopts two-pack bead structure can improve anti-dust performance and keep off oily effect, but the dust ring of this utility model setting is separate type, and volume is large, and the material expending is more.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, a kind of output shaft of gear-box oil sealing is provided, not only can effectively improves anti-dust performance and the oily effect of gear, and adopt two-pack lip and the combined structure of felt can reduce felt volume saving material.
For achieving the above object, the utility model by the following technical solutions:
A kind of output shaft of gear-box oil sealing, comprise spring, metallic framework and outside sheathed rubber skeleton thereof, described spring is arranged on described rubber skeleton outside, the bottom of described rubber skeleton is provided with the main lip of interconnective sealing, sealing two-pack lip, the main lip of described sealing and described sealing two-pack lip inside are equipped with some wires, described sealing two-pack lip end is provided with felt, and described felt is fixedly connected with sealing two-pack lip by adhesive sheet.
On the main lip of described sealing, be provided with multiple dentation projections away from a side of sealing two-pack lip.
On the main lip of described sealing, be provided with "eight" shape backflow line, described backflow line is between the main lip of described sealing and sealing two-pack lip.
The magnitude of interference of described sealing two-pack lip and output shaft of gear-box is designed to 0.20mm-0.50mm.
Described spring is hollow spring.
The lip of described sealing two-pack lip is arcuate structure.
The beneficial effects of the utility model:
Adopt after such structure, seal main lip and can ensure that gearbox internal lubrication oil is without leaking, and the particulate matter of the structural design of two-pack lip outside guarantee gearbox can not enter gearbox inside with in reducing main lip wearing and tearing, can avoid conventional single secondary lip oil sealing because conventional oil sealing only has a secondary lip, and the magnitude of interference of secondary lip diameter is larger, cause the heavy wear of the secondary lip of oil sealing, extraneous dust granule is easy to enter oil sealing inside, the main lip of oil sealing is worn and torn too early, cause leaking. After adopting the structure that seals two-pack lip, the magnitude of interference of sealing two-pack lip and output shaft of gear-box can be designed to 0.20mm-0.50mm, increase the diameter of two-pack lip, reduce the magnitude of interference, thereby alleviate the friction of parameter case output shaft to secondary lip, extraneous dust granule is difficult for entering oil sealing inside and corrodes main lip, protection oil sealing, final arrival improved the oil sealing object in service life; In addition, seal main lip and be equipped with some wires with sealing two-pack lip inside, not only can increase the intensity of rubber skeleton, and can increase the heat conductivility of sealed lip, thereby avoid the inhomogeneous oil seal failure causing of heat transfer of sealed lip; Secondly, be provided with felt in sealing two-pack lip end, felt is fixedly connected with sealing two-pack lip by adhesive sheet, and this design adopts two-pack lip and the combined structure of felt not only can effectively improve anti-dust performance and the oily effect of gear, and can reduce felt volume saving material.
This utility model not only can increase the heat conductivility of sealed lip, thereby avoids the inhomogeneous oil seal failure causing of heat transfer of sealed lip, and can reduce felt volume with gear in oily effect and saved material effectively improving anti-dust performance.
