Description
Technical field
A kind of oil sealing is the utility model is related to, more particularly to a kind of lever shaft oil sealing, belongs to motor accessory technical field.
Background technology
In oil sealing industry, currently a popular sealing main material has two classes：First, rubber elastomer, another is teflon plate
Material, so when present outside framework oil seal is used as sealing main material using rubber elastomer, its design is all that seal lip is adopted
With sharp lip, and sharp lip is easy to cause to damage in production, transport, assembling process, produces actual effect.Using polytetrafluoroethylsheet sheet
During as sealing main material, its design lip can not be sharp lip, but can not effectively avoid polytetrafluoroethylmaterial material again
The deficiency that elasticity is recovered caused by deformability, so as to cause lip to fail, leakage is produced, the model of oil sealing is all fixed
, just need to change different oil sealing models for different instruments, more change jobs very cumbersome.
Utility model content
The utility model provides a kind of lever shaft oil sealing, and the model that can efficiently solve nowadays oil sealing is all fixed
, just need to change different oil sealing models for different instruments, more change jobs the problem of very cumbersome.
In order to solve the above-mentioned technical problem, this practicality provides a kind of lever shaft oil sealing, including lever shaft, the lever shaft
Thread spindle is provided at both ends with, thread groove is provided with the thread spindle, the junction of the lever shaft and the thread spindle is set
There is inner rotary table, oil sealing is provided with the outside of the inner rotary table, oil hole, the outside of the thread spindle are provided with the inner rotary table
It is provided with Fixed latches.
As a kind of optimal technical scheme of the present utility model, the lever shaft and the thread spindle are zinc-plated steel lining axle.
As a kind of optimal technical scheme of the present utility model, the lever shaft and the thread spindle connect using electric welding is fixed
Connect, the Fixed latches are fixedly connected with the thread spindle using electric welding.
As a kind of optimal technical scheme of the present utility model, the inner ring of the oil sealing sets fluted, the inner rotary table
Outer ring be provided with the protrusion connection ring to be matched with the oil sealing upper groove.
As a kind of optimal technical scheme of the present utility model, the inner ring of the inner rotary table with it is described on the thread spindle
Thread groove is flexibly connected.
As a kind of optimal technical scheme of the present utility model, the oil sealing is made of fluorubber material.
The beneficial effect that the utility model is reached is：This kind of lever shaft oil sealing, use intensity is being ensure that, is improving and uses
On the basis of function, oil sealing can isolate the part for needing to lubricate in transmission parts with output part, be unlikely to allow oil seepage,
The flexible connection of the thread spindle and inner rotary table of use, the convenient position for adjusting oil sealing, then will need that allots to give up by oil hole
Oil discharge, and the flexible connection using oil sealing and inner rotary table, it is convenient for changing the oil sealing of different model.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality
New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is the structural representation of the utility model lever shaft oil sealing；
In figure：1st, lever shaft；2nd, thread spindle；3rd, Fixed latches；4th, oil sealing；5th, thread groove；6th, inner rotary table；7th, oil hole.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in figure 1, a kind of lever shaft oil sealing of the utility model, including lever shaft 1, lever shaft 1 are provided at both ends with spiral shell
Line axle 2, thread groove 5 is provided with thread spindle 2, the junction of lever shaft 1 and thread spindle 2 is provided with inner rotary table 6, inner rotary table 6
Outside is provided with oil sealing 4, and oil hole 7 is provided with inner rotary table 6, and the outside of thread spindle 2 is provided with Fixed latches 3.
Further, lever shaft 1 and thread spindle 2 are zinc-plated steel lining axle, and service life length is more durable.
Further, lever shaft 1 is fixedly connected with thread spindle 2 using electric welding, and Fixed latches 3 are with thread spindle 2 using electric welding
It is fixedly connected, prevents that lateral deviation or fracture occurs during work.
Further, the inner ring of oil sealing 4 is set fluted, and the outer ring of inner rotary table 6 is provided with to match with the upper groove of oil sealing 4
