High temperature spring
compression springcompression spring is a spiral spring which bears axial pressure. its material section is mostly circular, and it is also made of rectangular and multi strand steel. generally, the spring is of equal pitch. the shapes of compression spring are cylindrical, conical, convex and concave, and a small amount of noncircular. there will be a certain gap between the coils of the compression spring. when the spring is subjected to external load, the spring will have a certain gap shrinkage deformation, storage deformation energy. variable pitch spring is more and more common, not just equal pitch spring, variable pitch spring can play a different role in different environments.
tension springThe tension spring can absorb and store energy, and has resistance to tension. Its initial tension is determined by the tightness of the tension spring coil. The initial tension can be adjusted to achieve the load in special applications. demand.
The tension spring is often compressed in a free position (under no load) and can have loops, hooks, holes or other geometrical components at the ends. In order for parts to stretch to the target position, they are frequently used to provide resilience.
torsion springA torsion spring is a helical spring that can apply torque or rotational force. The end of the torsion spring is connected to other parts. When those parts rotate around the center of the spring, the spring pushes them back to their original positions. Although this name may have other meanings. The torsion spring seems to act more like a deformation force than a torque. They can store and release energy or fix a mechanical part in a certain position by twisting the spring arm along the vertical axis of the spring body.
wave springIn the application environment with small space, Liyu wave spring can replace the traditional round spring. Generally speaking, the wave spring is only 30%~50% of the compression height of the round spring. When the same load is applied, the deformation of the round spring is greater.
