Steel With Nickel Plating Spiral Mini Torsion Spring For Door Lock
Torsion springs belong to the category of spiral springs. Torsional springs can store and release angular energy or statically hold a device by rotating a moment arm about the central axis of the spring body. The end of the torsion spring is fixed to the other components, and as the other components rotate around the center of the spring, the spring pulls them back to their initial position, generating torque or rotational force.
Such springs are usually close-fitting, but the springs are spaced to reduce friction. They exert resistance to rotation or rotational forces. According to the application requirements, the design of torsion spring rotation (clockwise or counterclockwise), so as to determine the spring rotation.
Torsion Spring is the extreme of Torsion springs, both single Torsion Spring and double Torsion Spring, and Torsion bar deformation should be in accordance with the design. Therefore, it is also difficult to master the design
Performance factor
Performance factors: spring stiffness, maximum deformation, maximum load and spin specifications.
Spring stiffness is the angular return torque per unit of angular displacement.
Maximum deformation refers to the maximum deformation of the spring before damage.
Torsion spring rotation is right, left and double.
