Abstract
The invention discloses a kind of dish-shaped external seal washers, are made of convex surface, concave surface, interior circular hole, external seal ring recess, exterior seal ring and external seal ring recess lip.The present invention can make the exterior seal ring tensioner on exterior seal ring slot in corresponding sleeve by the stress deformation on convex surface, concave surface, to achieve the effect that convenient sealing.The dish external seal washer also has both the function of washer while sealing, can be widely applied to the sealing or firm between the axis of mechanical transmission mechanism and set, belongs to a kind of novel seal washer.
Description
Technical field
The present invention relates to a kind of washer, especially a kind of washer having sealing function.
Background technology
In general, a degree of sealing is needed between axis and axle sleeve, in order to which oil sealing or gas either prevent ash
Dirt, although the sealing ring of the prior art can be sealed to a certain degree, less effective.
Invention content
To solve the above problems, the present invention provides a kind of dish-shaped external seal washer.
The technical solution adopted by the present invention to solve the technical problems is：It is a kind of dish external seal washer body by convex surface,
Concave surface, interior circular hole, external seal ring recess, exterior seal ring, external seal ring recess lip composition；The interior circular hole is located at main center, institute
It states external seal ring recess to be located on the outer edge of main body, external seal ring recess lip is located at the both sides of the external seal ring recess；It is described outer
Exterior seal ring is equipped in seal groove.
Further, the cross sectional shape of external seal ring recess is rectangle or semicircle or trapezoidal or triangle.
Further, the surface of main body is equipped with bar-shaped trough.
Further, the shape of bar-shaped trough is straight line or curve or oblique line.
Further, the quantity of bar-shaped trough is 3-12.
Further, the thickness of main body is 1mm-3mm.
Further, the width of bar-shaped trough is 0.1mm-1mm.
Further, the surface of main body is equipped with annular groove, the width 0.1mm-3mm of annular groove.
Further, the number of turns of annular groove is enclosed for 1-10.
The beneficial effects of the invention are as follows：The present invention can be made by the stress deformation of convex surface, concave surface on exterior seal ring slot
Exterior seal ring tensioner is in corresponding sleeve, to achieve the effect that convenient sealing.The dish external seal washer is in sealing
The function of also having both washer simultaneously can be widely applied to the sealing or firm between the axis of mechanical transmission mechanism and set.

Specific implementation mode
To make technical scheme of the present invention be more clearly understood, specific embodiment makees into one the present invention below in conjunction with the accompanying drawings
Walk explanation.
As shown in Figure 1, a kind of dish external seal washer, main body 1 by convex surface 2, concave surface 3, interior circular hole 4, external seal ring recess 6,
Exterior seal ring 7, external seal ring recess lip 71 form；The interior circular hole 4 is located at 1 center of main body, and the external seal ring recess 6 is located at master
On the outer edge of body 1, external seal ring recess lip 71 is located at the both sides of the external seal ring recess 6；It is equipped in the external seal ring recess 6
Exterior seal ring 7.
Further, the cross sectional shape of external seal ring recess 6 is rectangle or semicircle or trapezoidal or triangle.
Further, the surface of main body 1 is equipped with bar-shaped trough 8.
Further, the shape of bar-shaped trough 8 is straight line or curve or oblique line.
Further, the quantity of bar-shaped trough 8 is 3-12.
Further, the thickness of main body 1 is 1mm-3mm.
Further, the width of bar-shaped trough 8 is 0.1mm-1mm.
Further, the surface of main body 1 is equipped with annular groove 9, the width 0.1mm-3mm of annular groove 9.
Further, the number of turns of annular groove 9 is enclosed for 1-10.
In use, interior circular hole 4 is sleeved on axis, exterior seal ring 7 of the external seal ring recess 6 on is filled in sleeve, is led to
It crosses to exert a force to main body 1 and squeeze, make main body 1 in radial stretching, so that exterior seal ring 7 is close to sleeve, reach sealing effect.
Above example can be combined with each other in the case where not being antagonistic mutually, reach further technical solution.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
