Wave Spring-Single Layer Wave Spring
单层波簧分为单层开口波簧和单层搭口波簧，该波簧适用于多种应用，可以精确可靠地在小变形和低中等的力值应用中发挥作用，特别适用于工作高度和工作空间较小的应用。 传统冲压波簧随着工作高度的降低，外径也会随之扩张，如果外径扩大至波簧的安装孔腔时，传统波簧会卡死在安装孔内。而开口波簧和搭口波簧很好的解决了这个问题，...
Crest to Crest Wave Springs
多层之间由一段连续钢丝绕制而成，所以对顶波簧也是一个稳定的弹簧结构，对顶波簧的特点是随着层数的增加，波簧的刚度会随着波簧层数按比例降低，而力值不发生变化，这样就会在更大的压缩空间内有着更接近的力值，也就是各种需要弹性的应用，即使有着很大的制造公差，对顶波簧也可以在这么大的公差范围内提供相似的力值。

带有支撑圈的波形弹簧可以将波簧弹力分散到整个支撑圈上下面，有效地降低了与波簧接触的材料其单位面积受到的摩擦力，所以无支撑圈对顶波簧适用于上下接触面为例如钢铁等硬度较高的材料，然而有些接触面为塑料或其他较软的材料，可以选用带有支撑圈的对顶波簧。

Wave spring介绍
Standard Wave spring
A wave spring, also known as a coiled wave spring or microwave spring, is a spring made up of pre-hardened flat wire in a process called on-edge coiling (also known as edge-winding). During this process, waves are added to give it a spring effect. The number of turns and waves can be easily adjusted to accommodate stronger force or meet specific requirements.
Wave spring is an elastic element with several peaks and valleys on a thin metal ring. It is usually used in the occasions where the load and deformation are not large, and the spring stiffness is required to be small and the axial preload needs to be applied.
[1] Wave spring structure type:
1. Partially overlapping single-layer wave springs, the total number of layers of wave springs in this structure is one layer: the ring is not closed; the ports overlap each other; the overlapping position is at the peak or trough; the wave number is greater than or equal to 3;
2.Open single-layer wave spring, the total number of layers of the wave spring is one layer; the ring is not closed, the opening position is at the peak or trough; there is a certain distance between the ports; the wave number is greater than or equal to 3;
3.Closed single-layer wave spring, the total number of layers of the wave spring in this structure is one layer; the ring is closed; the wave number is greater than or equal to 3;
4.Peak-to-valley multi-layer wave spring without supporting ring, the total number of layers of the wave spring in this structure is more than one layer; the number of waves in each layer is 2.5, 3.5, 4.5, etc.; There is no supporting ring at the end: the effective number of turns is equal to the total number of turns
5.There are multi-layer wave springs with supporting rings on the peaks and valleys.
The total number of layers of the wave spring in this structure is more than one layer; the wave numbers of the effective rings are 2.5, 3.5, 4.5...; the two layers that are in contact with each other are in contact at the peak and the trough : There is a flat ring at each end as a support ring; the effective number of turns is 2 less than the total number of turns；
6.Nested multi-layer wave springs. the total number of layers of wave springs in this structure is more than one layer; the wave numbers of effective coils are 3, 4, 5...; the lower surface of the upper coil is in contact with the upper surface of the lower coil
[2] Why choose wave spring？
Wave spring, on the basis of the same load as ordinary helical compression spring, wave spring can reduce the spring height by 50%
[3] Wave Spring Material Selection？
Generally choose alloy spring steel: SWRH72A/72B, SAE1070-1090, 50CrVA, 65Mn, etc.
Stainless steel: SUS304, SUS316, SUS631
High temperature resistant nickel-based alloys: Inconel718, Inconel X-750

[4] Dimensional tolerance zone selection
1.The inner and outer diameter limit deviation of the wave spring is stipulated in the following table
2.Thickness, the thickness limit deviation of the wave spring is specified in the following table
Note: Under the condition of guaranteeing the characteristic requirements, the thickness limit deviation can be properly adjusted during the manufacturing process, but the tolerance zone must not exceed the range specified in this table.
3.Free height, the limit deviation of free height of single-layer open and single-layer closed wave springs is specified in the table below. The limit deviation of free height of multi-layer wave springs is stipulated by the agreement between the supplier and the buyer. When there are characteristic requirements, the free height is used as a reference. The wave height difference of the same wave spring is stipulated in the table below.
[5] Stroke and Load Selection
1.Under the load of the specified height, the deformation of the wave spring should be between 15% and 70% of the maximum compression stroke h. If it exceeds this range, there will be deviations between the theoretical calculation value and the actual detection value
The limit deviation of the load P at the specified height is specified in the table below.
[6] Wave spring inspection items
1. Surface quality, the surface of the wave spring is not allowed to have burrs, cracks, scars and other defects that are harmful to use.
2. Geometry
2.1 Thickness, the thickness of the wave spring is measured at no less than 3 points at the middle diameter along the circumference with a pointed micrometer, and the average value is taken.
2.2 The outer diameter and inner diameter of the wave spring are measured with a vernier caliper with a division value not less than 0.02mm, and two points perpendicular to each other are measured. The outer diameter takes the maximum value and the inner diameter takes the minimum value.
2.3 Free height, the free height of the wave spring is measured on the platform with secondary precision, and the height of each wave peak is measured with a depth vernier caliper with a division value not less than 0.02mm, and the average value is taken.
3. Load
The load test of the wave spring is carried out on a testing machine with an accuracy of not less than 1%. The load when it is loaded to a specified height is measured. The hardness of the pressure plates at both ends must be above 52HRC, and the surface roughness Ra<1.6μm.
4. Permanent deformation
After the wave spring is compressed three times with the test load, the change in free height after the second and third compressions is measured. After the permanent deformation test, the free height of the wave spring should be within the limit deviation range.
5. Hardness
The hardness of the wave spring is in accordance with the provisions of GB/T 230.1, Part 1 or GB/T 4340.1. If the thickness is <1mm, it should be tested on a Vickers (or superficial Rockwell) hardness tester; if the thickness is ≥1mm, it should be tested on a Rockwell hardness tester. 4 points for each piece, the first point is not evaluated, and the average of the last 3 points is taken.
6. Fatigue test
Wave springs are tested on a fatigue testing machine with a constant amplitude sine wave load. The test is carried out on a single piece. Before the test, it must be pre-compressed for 0.15h0~0.20h0. The stress amplitude is determined through negotiation with the customer according to the life requirements.
