Description
Technical field
The present invention relates to a kind of axle rubber seal applied in drive apparatus, be specifically related to a kind of retainer ring that carries
Helical teeth arrangement interference design, have and float and the axle rubber seal of promptly function.
Background technology
Applying wide rubber seal to include oil sealing, dust ring in drive apparatus, pull bar seals, and piston envelope etc., due to it
Radially extenal fixation face i.e. axle rubber seal outer diameter contact face typically uses plane or the fixing design of O circle, or a few cases has
The least right-angle protrusion, only plays the function of frictional property, and its optimal magnitude of interference domain of walker is less, if the magnitude of interference is bigger than normal,
Can cause installation difficulty, and magnitude of interference meeting less than normal causes static seal to leak, even axle rubber seal external diameter is sent out with equipment cavity cognition
The phenomenon of raw skidding transfer.
Summary of the invention
It is an object of the invention to provide the axle rubber seal that a kind of radial direction extenal fixation face is helical teeth arrangement interference design, energy
The most effectively solve skidding and logy problem that above-mentioned tradition axle rubber seal magnitude of interference difficulty controls to cause, it is ensured that axle uses rubber
Glue seals and is easily installed, and seals reliable and firm position.And can beat at axle, swing use in drive apparatus bigger than normal, it is ensured that
Equipment operational reliability.
The present invention adopts the following technical scheme that
A kind of axle rubber seal of the helical teeth arrangement interference design carrying retainer ring, its outer diameter contact face, internal diameter contact surface or outer
It is arranged in parallel that the contact surface of footpath and internal diameter is provided with multiple helical teeth, and the outer diameter contact face of axle rubber seal uses cornice formula mistake
It is full of design, there is floating and promptly function.
Further technical scheme, the medial surface (i.e. by sealing fluid side) of described axle rubber seal main seal ring, outside
Face (i.e. away from sealing fluid side) or the two side can be provided with retainer ring, retainer ring and axle rubber seal main seal ring
Between with relative movement, thus the main seal ring in the middle of retainer ring can be realized and has the function fluctuated.
The quantity of described helical teeth is 3 or more than 3, and the angle of helical teeth and contact surface is under free state and compressive state
It is respectively less than 90 degree, can be towards sealing fluid side inclination, it is also possible to seal fluid side oblique arrangement dorsad, it is also possible to comprise
Towards sealing fluid side and sealing two kinds of helical teeth of fluid side dorsad.Helical teeth radial height is all higher than 1 millimeter.
Further, the present invention also can use all-in-one-piece axle rubber seal according to application demand, or axle used rubber
Glue seals and carries out cutting, becomes split-type shaft rubber seal.Axle rubber seal internal diameter also can be provided with one or more sealing lip
Sheet, seals and forms heat dissipation cavity between lips, and lips can oblique bending in the same direction, it is also possible to reversed dip bends.
Compared to existing technology, the invention have the advantages that (1) axle rubber seal external diameter design tooth depth is more than 1 millimeter
Parallel helical teeth, add several outside diameter seal line, improve static seal effect, and there is floating elastic and firmly grab wall
Power, can utilize fluid pressure and cavity to be adjacent to seal towards the helical teeth sealing fluid, and the helical teeth sealing fluid dorsad can be the most anti-
Only axle rubber seal is ejected sealing cavity by the pressure sealing fluid.(2) the axle cornice formula interference of rubber seal external diameter designs,
While ensureing to provide bigger external diameter decrement, it is not result in that bigger axle rubber seal internal diameter shrinks, does not interferes with
The magnitude of interference of sealing lip and the control of radial load, guarantee that external diameter fits tightly sealing with footpath in equipment annular seal space body simultaneously, non-slip,
And be easily installed.(3) the axle retainer ring of rubber seal both sides designs, it can be ensured that axle rubber seal main seal ring is being fixed
Ring directly radially fluctuates, and adapts to the swing of acutely beating of axle.(4) axle rubber seal cutting can be become split-type shaft
With rubber seal, install and need not detaching equipment when changing axle rubber seal.
