Abstract
The utility model discloses an energy saving environmental protection oil seal which consists of a skeleton coating layer, a skeleton, a lip mouth and a main lip mouth; the main lip mouth adopts a rubber elastomer; the contact surface of the main lip mouth and a rotating shaft is a plane and is provided with a spiral oil return line; the root part of the lip mouth is the seal oil side; an oil stop point is arranged on the oil return line; the energy saving environmental protection oil seal has the advantages of excellent elasticity of rubber, small holding force, energy saving and environmental protection, long service life, preventing blocking and damage during assembly, low requirements on processing precision and consistency, low friction coefficient, light countershaft abrasion, and low cost; moreover, the energy saving environmental protection oil seal can adapt large eccentricity and high speed rotation working conditions.
Description
Technical field
The utility model belongs to running shaft and uses the oil seal technique field, especially relates to the energy-conserving and environment-protective oil sealing that uses on a kind of engine mission.
Background technique
In the oil sealing industry, the popular main material of sealing has two classes at present: the one, and rubber elastomer, another is a polytetrafluoroethylsheet sheet, when so present outside framework oil seal adopts rubber elastomer as the sealing main material, its design proposal all is that seal lip adopts sharp lip, and sharp lip is easy to cause damage in production, transportation, assembly process, produces to lose efficacy.There is distinct disadvantage when adopting polytetrafluoroethylsheet sheet: be exactly the elasticity deficiency, cause that oil sealing is held tightly power is big, thereby increase frictional force, increased the power consumption of motor as the sealing main material.Oil sealing because the machining accuracy of assembled shaft chamfering and conformity are difficult to assurance, so often occur oil seal lip in the practical set by the situation of pressure, causes serious seal failure in assembly process simultaneously.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of and have that the excellent elasticity of rubber, the power of holding tightly are little, can clamping stagnation damage, machining accuracy in the energy-conserving and environment-protective, long service life, assembly process and coherence request is low, friction factor is low,, the energy-conserving and environment-protective oil sealing that can adapt to large eccentricity, high speed rotating operating mode low to axle light abrasion, cost.
The purpose of this utility model is to realize like this, a kind of energy-conserving and environment-protective kind oil sealing, form by skeleton coating, skeleton, lip and main lip, be characterized in that lip, main lip adopt rubber elastomer, main lip and running shaft surface of contact are that plane and surface of contact are provided with the helix oil drive back thread, and the root of lip is the sealing oil side.
In order further to realize the purpose of this utility model, can be on oil drive back thread, to be provided with only oil drop.
In order further to realize the purpose of this utility model, can be that the end at skeleton coating and main lip homonymy is provided with dust guard.
In order further to realize the purpose of this utility model, can be to be provided with in the main lip outside to prevent the lip texturing device.
In order further to realize the purpose of this utility model, can be that anti-lip texturing device is to be provided with annular protrusion or to be provided with spring in the main lip outside.
In order further to realize the purpose of this utility model, can be to be provided with shaft orientation reinforcing rib in the lip waist outside.
In order further to realize the purpose of this utility model, can be that described dust guard is the dustproof lip with skeleton coating one.
In order further to realize the purpose of this utility model, can be that described dust guard is that the prevent dust outside of lip of a end at skeleton coating and main lip homonymy is provided with nonwovens or felt.
In order further to realize the purpose of this utility model, the quantity that can be oil drive back thread is the 1-7 bar.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model oil seal lip and main lip adopt rubber elastomer, main lip and running shaft surface of contact are that plane and surface of contact are provided with the helix oil drive back thread, the root of oil seal lip is the sealing oil side, such one is to be easy to assembling: the seal lip of traditional rubber elastomer oil sealing all is designed to sharp lip, have gentle angle, clear and definite pasta angle, the utility model seal lip is plane shape, being inverted cone by oil pocket inside to the oil pocket outside stretches, the i.e. sealing lip that stretches by oily side direction gas side vertically, pack near a side of skeleton by the sealing lip root during oil sealing assembling, can prevent sealing lip stress deformation in assembly process, reduced in the assembly process the harm of lip, clamping stagnation can not take place in the assembly process, the situation of damage and pressure sealing lip; The 2nd, energy-conserving and environment-protective: compare traditional rubber elastomer point lip oil sealing, it is because of be provided with single head or multi-head spiral line oil drive back thread in the lip inboard, increased contact width with axle, be provided with only oil drop because of oil drive back thread simultaneously, oil can be recovered in the Seal cage, avoided oily leakage, so oil sealing can be designed to the effect that less radial force plays energy-conservation of consumption reduction, owing to adopt rubber elastomer as sealing material, its elastic return is obvious better than polytetrafluoroethylmaterial material, its starting friction moment of torsion reaches energy-conservation effect much smaller than the polytetrafluoroethylmaterial material oil sealing so also can play the reduction power consumption when particularly starting; The 3rd, adaptability is more extensive: the sealing lip width is wideer than traditional elastomer point lip oil sealing, and compares polytetrafluoroethylmaterial material, and elastomeric elastic return is significantly good, so more can adapt to circular runout or shake big occasion; Can be provided with annular protrusion or spring in the main lip outside near main lip place, can satisfy the power of radially holding tightly of main lip necessity like this, make main lip have enough sealings, avoid spilling of oil the sealing position by design; Can be provided with shaft orientation reinforcing rib in the lip waist outside,, adapt to bigger internal pressure, reduce the distortion at lip position, keep the shape at lip position, well keep the sealing of oil sealing to increase the rigidity at lip position; End at skeleton coating and main lip homonymy is provided with dust guard, can better play dustproof effect like this, avoids dust to enter in the oil sealing chamber, causes the damage of oil sealing sealing master lip.
