Abstract
The utility model discloses a rotation shaft oil seal consisting of a skeleton, a rubber body and a polytetrafluoroethylene piece (PTFE). The rubber body is closely combined with the polytetrafluoroethylene piece (PTFE). The polytetrafluoroethylene piece extends from oil side to gas side along axial direction. The polytetrafluoroethylene piece is provided with a oil return line, and a dustproof lip is arranged on the polytetrafluoroethylene piece root end. The utility model is characterized in simple assembling, no damage on the polytetrafluoroethylene (PEFE) lip port in assembly process, no risk of clamping stagnation and damage in assembly process, integrative seal and dustproof design, friction between lip port and shaft reducing and oil seal service life improving.
Description
One, technical field
The utility model belongs to running shaft and uses the oil seal technique field, especially relates to a kind of rotary shaft oil seal.
Two, background technique
At present, from technical data both domestic and external, polytetrafluoroethylene (PTFE) axle oil envelope has experienced a plurality of developing periods, a tangible problem is all arranged, that be exactly in the assembly process lip vulnerable, the dust excluder lips structure is complicated, requirement to assembling is relatively harsher, show as: need during assembling accurately to aim at, oil sealing setting tool surface roughness is had relatively high expectations, and certain cone angle requirement is arranged; All will there be strict fillet, circular arc, inclined-plane and surface roughness requirement in the position of the axle of oil seal lip process.
Three, summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provides a kind of and assemble in simple, the assembly process frictional force not damaging the risk that clamping stagnation, damage can not take place in polytetrafluoroethylene (PTFE) lip, the assembly process, incorporate sealing and dustproof design, alleviated lip and axle, improves the oil sealing rotary shaft oil seal in working life.
The purpose of this utility model is to realize like this, a kind of rotary shaft oil seal is made up of skeleton, rubber body and teflon plate, is characterized in that rubber body and teflon plate combine closely, teflon plate is stretched by oily side direction gas side vertically, and teflon plate is provided with oil drive back thread.
In order further to realize the purpose of this utility model, can be that the root end in teflon plate is provided with dust excluder lips.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts rubber body to be provided with to outwards being stretched by inside, the i.e. teflon plate (PTFE) that stretches by oily side direction gas side vertically, can prevent PTFE sheet stress deformation in assembly process, reduced in the assembly process harm to the PTFE lip, clamping stagnation, damage can not take place in the assembly process, easily assembling, no clamping stagnation; Teflon plate is provided with oil drive back thread, root end in teflon plate is provided with dust excluder lips, realized sealing, prevented dust in one, there is not independent dust excluder lips structure, reduced oil sealing and axle friction, thereby the reduction excessive power drain has improved oil sealing working life, adapts to higher environmental requirement;
Compare with existing PTFE axle oil envelope, omitted independent dust excluder lips structure, alleviated frictional force, improved oil sealing working life in the gas side; Aspect assembling, consistent because of assembly direction with the direction of PTFE disk, to the protection of PTFE lip, become simple, reliable, safe.
Four, description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Five, specific embodiments
Embodiment 1, a kind of rotary shaft oil seal, be that coated outside at L type skeleton 1 has rubber body 2, rubber body 2 is provided with by inside and outwards stretches, promptly to the teflon plate (PTFE) 3 that stretches by oily side direction gas side vertically, teflon plate (PTFE) 3 surfaces are provided with oil drive back thread 5, and the root end of teflon plate (PTFE) 3 is provided with dust excluder lips 4, and this has constituted a kind of structure of the present utility model.
Embodiment 2, and a kind of rotary shaft oil seal is on embodiment's basis, and skeleton 1 adopts the U type, and other and embodiment 1 are identical.
Claims (2)
1, a kind of rotary shaft oil seal, form by skeleton (1), rubber body (2) and teflon plate (3), it is characterized in that rubber body (2) and teflon plate combine closely, teflon plate (3) is stretched by oily side direction gas side vertically, and teflon plate (3) is provided with oil drive back thread (5).
2, a kind of rotary shaft oil seal according to claim 1 is characterized in that being provided with dust excluder lips (4) in the root end of teflon plate (3).
