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.When the spring twists, the material is in a tensile or shear state as mentioned in the torsion calculation, so the torsion Angle limit is ultimately caused by the failure of the material, which cannot be restored to its original state when plastic deformation occurs. Of course, the Von Mises stress calculated by the fourth strength theory is the maximum strength that the material can withstand. Combined with the length of the spring, the maximum allowable torsion Angle can be calculated.
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.

Reference Drawing
1. What is torsion spring rate?
A: The definition of torsion spring rate is the amount of force per 360 degrees of radial travel. Torsion force is typically noted in pounds or newtons based on English or metric measurements. This can be further broken down into the amount of force per degree by simply dividing by 360 degrees.
2. Where should torsion springs be used?
A: A torsion spring is commonly used in clothes pins, clipboards, swing-down tailgates and garage doors. Other application types include hinges, counterbalances and lever returns. Sizes range from miniature, used in electronic devices, to large torsion springs used in chair control units.
3. What is the difference between tension and torsion?
A: As nouns the difference between tension and torsion.
4. Do torsion springs work in both directions?
A: For a correct solution, a right-hand wound torsion spring should be mounted on one side, and a left-hand wound one on the other. A torsion spring must always be loaded in the direction of the spring wire so the spring body closes.
5. What is the difference between helical and torsional springs?
A: A helical looped design is the most common design for torsion springs, which consists of a coiled metal wire that is twisted tighter and tighter by sideways forces that are applied on either a left-hand or a right-hand helix.
6. What cools the clutch disc?
A: The friction forces that exist on the respective friction surfaces of the clutch disk are unevenly distributed. The clutch is cooled by a flow of cooling air that is led through the clutch bell that encloses the clutch and that defines a housing.
7. What is hydraulic clutch?
A:Hydraulic Clutch is one of the Type of Automobile Clutch. In this Type of Clutch, Fluid is used to Operate the Clutch. The advantage of Hydraulic Clutch is Less Effort is required to Press the Clutch Pedal.
8. What does the clutch friction disc always rotate with?
A: The clutch disc is splined to the input shaft of the transmission. The disc itself rests between the flywheel and the pressure plate, both of which rotate with the engine. So the clutch disc is spinning with the transmission, and on either side of it is a metal surface which rotates with the engine.
