Technical field
The utility model belongs to spring technical field, and in particular to a kind of scroll spring.
Background technology
Plane scroll spring, clockwork spring is commonly called as, is to be formed with steel band coiling, in use, its one end is fixed, separately
After the action torque of one end, material produces elasticity of flexure deformation.After active force disappears, the elastic potential energy release of spring savings is allowed to
Reset condition is returned to, this caused torque claims the output torque of spring.The plane scroll spring of non-contact type, it is commonly used to produce
Raw anti-torque, such as it is used as the holddown spring of carbon brush for electric machine.
When plane scroll spring is acted on by external force, spring outmost turns under tension deformation, due to plane scroll spring by
Steel band, which rolls, to be formed, and recoil of spring ability is poor, when pulling force is excessive, or even the situation that spring is straightened occurs, having a strong impact on makes
With.
