Industrial Spraying Treatment Torsion Spring 0.07mm~12mm For Machinery
Introduction
A torsion spring by rotating its ends along its axis to work the spring; flexible storage elastic bodies when mechanical energy that is, a twist. When twisting, it applies torque in the opposite direction, which is proportional to the amount of twist (angle).
Parameters
d (spring wire diameter): This parameter describes the diameter of the spring wire.
Dd (maximum diameter of mandrel): This parameter describes the maximum diameter of the spring shaft in industrial applications, with a tolerance of ±2%.
Di (inner diameter): The inner diameter of the spring is equal to the outer diameter minus twice the wire diameter. During the working process of the torsion spring, the inner diameter can be reduced to the diameter of the mandrel,
The inner diameter tolerance is ±2%.
De (outer diameter): equal to the inner diameter plus twice the wire diameter. During the working process of the torsion spring, the outer diameter will become smaller, with a tolerance of (±2%±0.1) mm.
L0 (natural length): Note: the natural length will be reduced during the working process, with a tolerance of ±2%.
Ls (support length): This is the length from the central axis of the spring coil body to the spring support, with a tolerance of ±2%.
An (maximum torsion angle): the maximum torsion angle of the torsion spring, with a tolerance of ±15 degrees.
Fn (maximum load): the maximum force allowed to act on the torsion spring support, with a tolerance of ±15%.
Mn (Maximum Torque): Maximum allowable torque (Newton*mm), tolerance ±15%.
R (spring stiffness): This parameter determines the resistance of the spring when it works. The unit is Newton*mm/degree, and the tolerance is ±15%.
A1&F1&M1: (torsion angle, load and torque): The following formula can calculate the torsion angle A1=M1/R. Knowing the load, the formula M=F*Ls can be used to calculate the torque.
Support position: The support of torsion spring has four positions: 0°, 90°, 180° and 270°
Spiral direction: the right-handed spring rotates counterclockwise, the left-handed spring rotates clockwise.

Application of Torsion Springs
Aviation, automotive, motorbike, bicycle, automatic equipment, household appliance, medical device ,toy, telecommunication, computer, instrument and meter, furniture, electric tools, mold and other industries.
- The torsion bar is a straight bar of metal or rubber rods, the torque applied to the end portion thereof subjected to twisting about the (shear stress) axis thereof.
- A more refined form of sensitive instruments used, called twisted fibers in a wire, glass or quartz fiber composition under tension, the fibers twisted about its axis.
- The coil is a spiral torsion spring (coil) shape of a metal rod or wire, twisted by applying a lateral force in the axial end portion thereof (moment) of the windings occurs, so as to twist the coil tighter.
- Clocks use a spiral-wound torsion spring (a form of spiral torsion spring in which coils are wound on each other instead of being stacked) sometimes called "clock spring" or colloquially called the mainspring. These types of torsion springs are also used
