A torsion spring is a helical elastic component designed to generate torque and store angular energy in rotational mechanisms. Wire diameter typically ranges from 0.3 to 18 millimeters, and mean coil diameter varies between 5 and 180 millimeters. The shear modulus of spring steel is approximately 79 gigapascals, and allowable bending stress ranges from 600 to 1200 megapascals. Effective working angle is defined between 30 and 270 degrees depending on design. The torque rate is calculated using k equals Ed to the fourth power divided by 10.8nD. The spring index is commonly selected between 4 and 12 to control stress concentration.
The structure consists of a helical body with two straight or angular legs measuring 5 to 250 millimeters in length. The number of active coils typically ranges from 2 to 15 to achieve required angular stiffness. Stress relief heat treatment is performed between 250 and 420 degrees Celsius. Final hardness of carbon steel after treatment ranges from 44 to 52 HRC. Maximum allowable stress at the leg junction is limited to less than 80 percent of yield strength. Quality control includes torque angle testing, fatigue evaluation up to 10^6 cycles, and angular deviation measurement within ±1 degree.You can order and buy Coil springs from Iran by contacting us through whatsaap and email.

Introduction to Common Types of Torsion Springs in iran
Torsion springs are categorized based on geometry and function into standard types . The most common is the standard torsion spring, featuring a cylindrical body and straight legs, applying torque in one direction only . For applications requiring bi-directional force, a double torsion spring is used, which consists of two independent left-hand and right-hand springs wound together to produce torque in both directions . In space-constrained systems needing variable torque, conical torsion springs with variable pitch and progressive resistance are employed . Preloaded torsion springs, manufactured with initial tension, deliver immediate torque upon installation . Selecting each type requires precise calculation of parameters like the spring rate k, measured in Newton-millimeters per degree N·mm/deg, and the maximum angular deflection φ .
