Abstract
The utility model discloses a high speed PTFE combined whirling oil cover and consists of a rubber body, an outer framework, a polyfluortetraethylene lip and an inner framework. The utility model is characterized in that the rubber body, the outer framework and the polyfluortetraethylene lip are connected together on the inner framework. The polyfluortetraethylene lip is connected with the inner framework to form sealing. The utility model can prevent the disablement of the oil cover in the transportation and assemble caused by turnover, break or damage of the lip as the combined integrity design. Moreover, the utility model has the advantages of small abrasion of the sealing lip, small friction torque and long service life.
Description
One, technical field
The utility model belongs to running shaft and uses the oil seal technique field, especially relates to the teflon rotary oil seal that uses under a kind of high velocity environment.
Two, background technique
At present, in the design of high speed PTFE (teflon) rotary oil seal, exist many application schemes, but because its structural reason, failure analysis from the using process generation, all exist because assembling, failure conditions such as oil sealing PTFE (teflon) the lip distortion that the transportation reason causes, fracture, breakage, upset, 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, otherwise oil seal lip is vulnerable to injury; Oil seal lip easy deformation in the transportation process.
Three, goal of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of simple in structure, good sealing effect, installation easily, the high speed rotating oil sealing of convenient transportation, long service life.
The purpose of this utility model is to realize like this, a kind of high speed PTFE combination rotary oil seal, form by rubber body, outer skeleton, teflon lip sheet and inner frame, be characterized in that rubber body, outer skeleton and teflon lip sheet are one and are positioned on the inner frame, teflon lip sheet contacts with inner frame and forms sealing.
In order further to realize the purpose of this utility model, can also be to turn up for " L " shape and skeleton in the end face cross section of inner frame.
In order further to realize the purpose of this utility model, can also be teflon lip sheet and the contact seal of inner frame face.
In order further to realize the purpose of this utility model, can also be that running shaft and inner frame interference fit realize sealing.
In order further to realize the purpose of this utility model, can also be that the surface of contact of teflon lip sheet and inner frame is provided with groove.
In order further to realize the purpose of this utility model, can also be that the opposing side of the surface of contact of teflon lip sheet and inner frame is provided with groove.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts combination seal, integrated design, inner frame and running shaft are interference fit, closely contact, prevent that sealing medium from leaking from the diameter of axle, the seal of being made up of rubber body, outer skeleton, teflon lip sheet contacts with the inner frame outer surface and seals, prevent that sealing medium from leaking, teflon lip sheet contacts with the outerplanar of inner frame, the sealing of formation maze type prevents that effectively dust from entering oily side from atmospheric side; The utility model adopts combined integrated design, can prevent oil sealing in transportation, in the assembling, lip upset, fracture, damaged and cause the phenomenon of oil sealing sealing disabler to take place take place, help the assembling of oil sealing, the cross section of teflon lip sheet and inner frame matter contacting point is triangle or crawler belt shape, helps reducing the radial force of main lip, reduces friction, increase the followability of oil sealing, increase the service life, sealing lip contacts with inner frame, has avoided the wearing and tearing of axle.
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.
Fig. 3 is another structural representation of the present utility model.
Five, specific embodiments
Embodiment 2, and a kind of high speed PTFE combination rotary oil seal is with reference to Fig. 2, be on embodiment 1 basis, the end face part of inner frame 4 becomes " L " shape and skeleton turns up, and teflon lip sheet 3 is provided with triangular groove 5 with the surface of contact of inner frame 4, and other and embodiment 1 are identical.
Embodiment 3, and a kind of high speed PTFE combination rotary oil seal with reference to Fig. 3, is on embodiment 2 basis, and teflon lip sheet 3 is provided with crawler belt connected in star 5 with the opposing side of the surface of contact of inner frame 4, and other and embodiment 2 are identical.
