Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to an anti-fatigue and anti-decarburization annular spring. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material will deform under the action of external force and return to its original shape after the external force is removed. It is also called a "spring" and is generally made of spring steel. There are many types of springs. According to their shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc.

[0003] Springs act as shock absorbers and buffers in machinery. However, over a long period of time, springs are prone to superelastic potential energy when used. Long-term extreme stretching or compression will cause the elastic potential energy of the spring to decrease. The existing anti-decarburization annular spring has a ring-shaped spring structure when in use, and the structure is relatively simple. In order to avoid the decrease in the elastic potential energy of the anti-decarburization annular spring, a limiter is usually installed axially of the anti-decarburization annular spring. However, when in use, a separate fixing seat needs to be provided for the limiter, which increases the space occupancy and the cost of use. Therefore, an anti-fatigue and anti-decarburization annular spring is proposed to solve the above-mentioned problems. Utility Model Content
