Torsion Spring

Torsion Spring is helical springs that exert a torque or rotary force. The ends of torsion springs are attached to other components, and when those components rotate around the center of the spring, the spring tries to push them back to their original position. . Torsion springs can be designed to work in a clockwise or counter-clockwise rotation, thus determining the direction of the wind. Common torsion springs are used in clothes pins, clipboards, swing-down tailgates and garage doors.Torsion springs are used for hinges, counterbalances and lever return applications.Torsion Springs perform best when supported by a rod or tube. Torsion Springs Parameters: Dimensions: Inner Diameter, Outer Diameter, Wire Diameter, and Spring Length. The Inner Diameter is specified when the spring is required to slip over a mandrel with sufficient clearance to operate freely. The Outer Diameter is specified when the spring is required to fit into a circular hole with sufficient exterior clearance to operate freely, or if there are outer housing clearance issues. The Spring Length is the length of the spring coil. Spring Rate is the angular return torque provided per unit of angular displacement. Maximum Deflection is the maximum rated angular deflection of spring before damage. The Wind of the torsion spring can be right hand, left hand, or double torsion.
