Description

High-strength wave spring

Technical Field

The utility model belongs to the technical field of wave springs, and particularly relates to a high-strength wave spring.

Background

The wave spring is an elastic element with a plurality of peaks and valleys on a metal thin circular ring. The wave spring is usually applied to the occasions that the load and the deformation are not large, the spring stiffness is required to be small, and the axial pre-pressure is required to be applied, the wave spring is particularly suitable for the application needing weight reduction and the application limited by a small installation space, and the typical application fields of the wave spring comprise: aerospace, precision machinery, hydraulic seal and high-end motor etc. wave spring has a plurality of ripples pad units to constitute, and the area of contact is usually less between some present ripples pad units, often is exactly a point, in case have stronger pressure, stagger easily between the ripples pad unit, damage, compressive strength is less.

Disclosure of Invention

Aiming at the problems in the prior art, the utility model aims to provide a high-strength wave spring to solve the problems that the existing wave spring and wave cushion units are easy to stagger and damage, and the compressive strength is small.

In order to solve the technical problems, the utility model adopts the technical scheme that:

the utility model provides a high strength ripples spring, includes that ripples fills up unit, upper end ripples and fills up and lower extreme ripples fills up, and the ripples spring includes that a plurality of ripples fills up the unit, and ripples fills up the unit and be provided with arch and recess, two adjacent the arch and the recess of ripples pad unit are corresponding, the lower extreme of bellied upper end and recess all is provided with the top, and the ripples of the top fills up the unit and is provided with the upper end ripples and fills up, and the ripples of bottom fills up the unit and is provided with the lower extreme ripples and fills up.

Furthermore, the bulges and the grooves of two adjacent wave pad units are fixedly connected.

Further, the top end of the upper end of the protrusion corresponds to the top end of the lower end of the groove.

Furthermore, the section of the top end is trapezoidal, and the outermost end surface of the top end is larger than the inner end surface.

Furthermore, the tangent plane of the upper end wave pad and the lower end wave pad is trapezoidal, and the outer end surface of the upper end wave pad and the outer end surface of the lower end wave pad are larger than the inner end surface.

Furthermore, a chamfer is arranged at the joint of the protrusion, the groove and the top end.

Has the advantages that: compared with the prior art, the method has the following advantages:

this high strength ripples spring is adjacent is not a point but a face between 2 ripples pad units, can bear bigger pressure, and the top is trapezoidal moreover, the local area of contact between 2 ripples pad units further strengthens, improve compressive strength greatly, even receive high pressure ripples pad unit between also can not stagger easily, damage, upper end ripples pad and lower extreme ripples pad tangent plane also are trapezoidal simultaneously, also can further improve compressive strength, indirect improvement life.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the high strength wave spring of the present application includes a wave cushion unit 1, an upper wave cushion 2 and a lower wave cushion 3, the wave spring includes a plurality of wave cushion units 1, and the wave cushion unit 1 is provided with a protrusion 101 and a groove 102, the protrusion 101 and the groove 102 of two adjacent wave cushion units 1 correspond to each other, and the protrusion 101 and the groove 102 of two adjacent wave cushion units 1 are connected, the upper end of the protrusion 101 and the lower end of the groove 102 are both provided with a top end 4, two adjacent wave cushion units 1 are connected by the top end 4, the top end 4 is a plane and is not an arc surface, so that the two adjacent wave cushion units 1 are not in contact with each other at one point but in contact with each other, thereby improving the contact area and the compressive strength, and even if the wave cushion units are subjected to a high pressure, the wave cushion units cannot be easily staggered, 2 are damaged, and the wave cushion unit 1 at the top end is provided with the upper wave cushion 2, the lowermost wave pad unit 1 is provided with a lower wave pad 3.

The protrusions 101 and the grooves 102 of two adjacent wave pad units 1 are fixedly connected, so that the connection strength and the stability are improved.

The top end 4 of the upper end of the protrusion 101 corresponds to the top end 4 of the lower end of the groove 102, and the top end 4 is a plane instead of a cambered surface, so that two adjacent wave pad units 1 are contacted not at one point but at one surface, the contact area is increased, and the compressive strength is also improved.

The tangent plane of top 4 is trapezoidal, and the outermost terminal surface of top 4 is greater than the interior terminal surface, improves the connection area between two adjacent wave pad units 1, makes wave pad unit 1 can bear more pressure, improves compressive strength.
