Single Turn Gap Wave Spring Washer Stainless Steel Size 2mm-1500mm

Description
The open single-layer wave spring, the total number of layers of the structure wave spring is one layer; The ring is not closed, and the opening position is at the crest or trough of the wave; There is a certain distance between the ports; Wave number is greater than or equal to 3

The wave spring is a precision flat wire compression spring, especially suitable for installation in parts where other springs cannot meet and space is limited. The counterwave spring is made up of continuous winding and stacking of wire, and its elastic coefficient is proportional to the number of turns of the spring. Typical applications are scenarios that require medium and low spring coefficients and medium and low force values with large deformation amounts.
The characteristics of the wave spring

Since the total height and working height of the corrugated spring are lower than that of the traditional round wire spring, the space size of the parts can be reduced by up to 50%. The corrugated spring is made of 17-7PH stainless steel, which has the characteristics of high tensile strength and fatigue resistance, and the high stress performance is better than that of carbon steel spring. The wave spring can be used in a working environment of up to 200 ° C, and is passivated while maintaining corrosion resistance, and its appearance is also bright and beautiful.

The life of the wave spring

The life of the wave spring is mainly related to the different compression amount and the stress ratio of the material during the compression process of the wave spring. When used at the minimum working height, the normal life is about 10,000 times, if you need to improve the service life of the waveform spring, you need to reduce the use of compression, reduce more than 50%, the theoretical life can be increased to 1 million times.

The application of wave spring

As a bearing device, the wave spring can compensate for the change in assembly size while exerting its load function. When the spring is pressed to the gradient or instantaneously reaches the preset working height, the load can be accumulated to produce an unrestricted range of force values. The load is directly proportional to the shape variable of the wave spring, so that it has an accurate spring coefficient. The corrugated spring requires very little space to perform its performance in the operation, so it is particularly suitable for applications where axial or radial space is limited, such as pressure relief valves, surface seals, sliding clutches, bearing bath towels, fluid valves, oil valves, floating gears, positioning preload devices.

Wave spring application cases

1. Bearing preload

Wavy springs can be used for bearing preload effect devices. The wave spring always provides a suitable elastic force during the operation of the bearing, which is mainly used to eliminate the movement and vibration of the bearing, and can also reduce the working noise of the bearing, which greatly improves the running smoothness and service life of the bearing.

2. Electrical connector

The corrugated spring is used to connect the buckle and the cap of the electric connector. In the compression process of the wave spring, there is always a locking force between the card pin and the card slot of the electric connector, so that the two are closely connected without slipping out.

3. Separate the bearing

The elastic element flexibly connects the separation bearing to the separation sleeve. In the process of the coupling between the bearing and the clutch, the additional radial force caused by the eccentricity causes the elastic element in the automatic aligning bearing to produce elastic deformation or radial slip, and realizes the automatic comparison between the rotating axis of the bearing and the rotating center of the clutch.

4. Seal the water pump

The water seal leakage can be effectively reduced by using the wave spring's characteristics of elasticity, pretension, compensation and buffering, as well as its advantages of uniform and stable elasticity and good follow-through. And the specific pressure of the spring of the water seal will be greatly reduced, and it can also effectively reduce the amount of friction and wear, and improve the durability of the water pump.
