Abstract
The utility model discloses a kind of fusiform gyrus oil line outside framework oil seal, it comprises outer oil seal, oil tight skeleton, annular spring, described oil tight skeleton is arranged at inside outer oil seal, described outer oil seal is provided with main lip, secondary lip, described main lip coordinates with annular spring, described main lip place is provided with oil drive back thread, and described oil drive back thread is shuttle shape.This oil sealing makes oil drive back thread also can play good oil sealing effect at the low rotational speed; The main lip place swabbing pressure of oil sealing is high, and oil sealing effect improves 2-3 doubly than original structure, through stand test rotating speed at about 100r/min time oil drive back thread effect obvious, oil sealing is respond well.
Description
Technical field
The utility model belongs to the oil sealing for motor car engine, vehicle bridge, gearbox, is specifically related to a kind of fusiform gyrus oil line outside framework oil seal.
Background technique
Generally, the main purpose that oil sealing is provided with linear type oil drive back thread is: when oil sealing rotates and reaches certain rotating speed, under the influence of centrifugal force, oil storage side can form certain swabbing pressure to air side, forms the object sealing and prevent lubricant oil from leaking; The oil drive back thread of original technology is generic linear formula, and namely rotational speed has a strong impact on sealability; When rotating speed lower than 500r/min time, pressure dissipation do not assemble, can not swabbing pressure be produced, oil drive back thread action deprivation, not have oil sealing object, just there will be oil leakage phenomenon, product failure.
Summary of the invention
In order to overcome the problems referred to above that prior art field exists, the purpose of this utility model is, provide a kind of fusiform gyrus oil line outside framework oil seal, oil sealing effect promotes further, enhances the adaptability of oil sealing sealing, reliability.
The fusiform gyrus oil line outside framework oil seal that the utility model provides, it comprises outer oil seal, oil tight skeleton, annular spring, described oil tight skeleton is arranged at inside outer oil seal, described outer oil seal is provided with main lip, secondary lip, described main lip coordinates with annular spring, described main lip place is provided with oil drive back thread, and described oil drive back thread is shuttle shape.
The fusiform gyrus oil line outside framework oil seal that the utility model provides, its beneficial effect is, this oil sealing makes oil drive back thread also can play good oil sealing effect at the low rotational speed; The main lip place swabbing pressure of oil sealing is high, and oil sealing effect improves 2-3 doubly than original structure, through stand test rotating speed at about 100r/min time oil drive back thread effect obvious, oil sealing is respond well.
