Wave springs are generally a type of compression spring that is used in many applications and requires a consistent force when the spring is compressed over a large distance range. The type of end you have to select for a wave spring is very important to the overall functionality of the wave spring in your application. This guide will educate the user on the various kinds of major wave spring end types available in the market and how to choose special parts from the available wave spring manufacturers.
Plain Ends
Plain ends are the least complex end form of the wave springs. The last two ends are left without any alteration from the standard structure or design of the ends of a typical electrical cable. The benefit of plain ends is that they are simple and inexpensive to produce. Also, plain ends enable you to add flat thrust washers when necessary to distribute the load on the spring ends.
Closed and Ground Ends
Apart from plain ends, most wave spring manufacturers provide their clients with closed and ground ends. In this end configuration, the two ends of the wave spring material are sealed and sharpened to provide round shapes. Closed ends eliminate the possibility of the edges cutting into other surfaces in the construction project. Moreover, they enable load dispersion without the need for supplementary thrust washers. If your application is space-limited, then special parts with closed and ground ends are preferable.
Squared and Ground Ends
Squared and ground ends offer the benefits of ground ends to prevent harm from sharp edges. In addition, they offer more load-bearing capability than plain-end wave springs. In this type, the open ends are flattened to make the surface square rather than a closure of the coils. Afterwards, the corners of the edges are also sanded to ensure that there are no sharp edges or corners on the surface.
Tang Ends
In some of the heavy loads, tang ends are the most secure type of ends that can be used. In this type, small tangs or tabs are formed at the two open ends that can be used to contain the wave spring through various means. Some options include:
- Staked tangs: Tangs are staked to lock spring
- Bent tangs: Tangs are bent over to hold the spring in place
- Tabbed tangs: Small tabs formed to connect the spring to the counterpart part
Tang ends ensure a strong connection of the wave spring even under cyclic loads. While they demand some extra turning, tang ends help to eliminate axial movement or slipping of the spring. Therefore, they are very suitable for applications where the device is likely to be subjected to shock and/or vibration.
To Conclude
End configuration is a critical aspect that influences the working of wave springs in various industries. So, it is advisable to consult reputed special parts and wave spring manufacturers to help you make the selection, depending on your needs.
