Problems solved by technology

However, since the sealing spring is not a monolithic structure, it cannot provide a uniform lateral preload force for the seal. If the two ends of the spring are lap-welded, the complexity of the process will be increased; and in the working state of the seal, the annular coil spring The preload force is small, such as Figure 10 As shown, so under higher working pressure, it cannot make the seal achieve the ideal sealing effect

Embodiment Construction

[0025] Such as Figure 5 or Image 6 As shown, this embodiment is a preferred embodiment of the present invention. First, we make the raw materials into Figure 4 The illustrated ring-shaped planar structure 4 with a rectangular opening (as long as it is a ring-shaped planar structure, it does not have to be the ring-shaped planar pattern of this embodiment; other ring-shaped planar patterns are also protected by the present invention Range), and then use a circular cylinder (not shown in the figure) to bend it into Figure 5 The cross section shown is a V-shaped ring structure 5, which is as follows Figure 5 An integral side pressure V-shaped spring 5 with a ring structure connected end to end is shown. The center line of the final V-shaped spring is determined according to the axis of the aforementioned annular cylinder. Because the integral side pressure V-shaped spring 5 of the present invention is made into an integral ring shape, it can bear the external force from the inn...

Abstract

The invention discloses an integrated side pressure V-shaped spring. The basic parameters of the integrated side pressure V-shaped spring include the material thickness and the width and height of a single-side opening of the spring. The integrated side pressure V-shaped spring is formed by directly bending a plane material by an annular column. The axis of the annular column is the center line of the spring. The single-side opening of the spring is a variable and changes along with changes of the angle of a conical head of the column. The central cross section of the spring is of left and right V-shaped openings. The angle theta of each V-shaped opening is smaller than 180 degrees. The two sides of the V-shaped openings can be of the same height and can also be of the different heights. The whole spring is of an annular structure.

Description

Technical field [0001] The invention relates to a spring, in particular to an integral side pressure V-shaped spring capable of realizing multi-directional stress compensation and a sealing device with the spring. Background technique [0002] Annular sealing ring is a very widely used mechanical part. At present, these ring sealing rings are used to be made of rubber materials and plastics, and are used for dynamic sealing between shaft and hole; most ring sealing rings have a spring embedded in them. [0003] Because the prior art V-shaped spring is made by bending a strip-shaped plate with a rectangular notch along the midline parallel to the length, it is still strip-shaped after bending, with a V-shaped cross section. The length of the spring is usually It is designed to be equal to the center circumference of the annular groove of the sealing ring. After the spring is inserted into the annular groove of the sealing ring, the end and the end just touch each other, but because ...
