Problems solved by technology

[0003] The traditional torsion spring is made of cylindrical spring steel. Since the production is made by winding, the inner deformation pressure of the spring steel is greater than the outer deformation pressure, and the spring elasticity decays faster.

Embodiment Construction

[0018] The concept, specific structure and specific effects of the present invention will be clearly and completely described below in conjunction with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. The various technical features created by the present invention can be combined interactively on the premise of not contradicting each other.

[0019] see Figure 1-2 , a long-life torsion spring, characterized in that it includes a spring body 1, the spring body 1 is made of spring steel, one side of the spring steel is cylindrical, and the other side is wedge-shaped. The unit deformation force of the wedge-shaped side of the spring steel is smaller than that of the cylindrical side, and the wedge-shaped side is set on the side with larger contraction deformation of the torsion spring to relieve denaturation pressure and effectively prevent fatigue deformation.

Abstract

The invention provides a torsion spring long in service life. The torsion spring is characterized by comprising a spring body; the spring body is made of spring steel; one side of the spring steel is cylindrical; and the other side of the spring steel is in a wedge shape. The unit deforming force of the wedge-shaped side of the spring steel is smaller than that of the cylindrical side, the wedge-shaped side is arranged on the side, where shrinkage deformation is large, of the torsion spring so that the degeneration pressure can be alleviated, and thus fatigue deformation can be effectively prevented.

Description

technical field [0001] The invention relates to a spring, in particular to a long-life torsion spring. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. Also known as "coil spring". Generally made of helical spring steel. The types of coil springs are complex and diverse. According to the shape, there are mainly helical coil springs, scroll coil springs, plate coil springs, special-shaped coil springs, etc. [0003] The traditional torsion spring is made of cylindrical spring steel. Since the production is made by winding, the inner deformation pressure of the spring steel is greater than the outer deformation pressure, and the spring elasticity decays faster. Therefore, there is a need for a long-life torsion spring. Contents of the invention [0004] In order to solve the abov...
