Torsion Springs

Torsion Springs is one of the more complicated design principles among all spring types, and the changes of the type are also quite active, so the theory involved in the design is also the most complicated. Torsion springs are coil springs. The ends of torsion springs are fixed to other components, and as other components rotate about the center of the spring, the spring pulls them back to their original position, creating a torque or rotational force. Torsion springs can store and release angular energy or statically fix a device by rotating a lever around the central axis of the spring body. These springs are usually tight body, however, there is a pitch between the coils to reduce friction. They create resistance to rotation or rotational external forces. Depending on the application requirements, design the direction of rotation of the torsion spring (clockwise or counter-clockwise) to determine the direction of the spring. The turns are either tightly wound or spaced apart to accommodate torsional loads (at right angles to the spring axis). The end of the spring can be wound as a hook or straight torsion arm.

Be-Cu metal spring shop offer custom torsion springs including industrial torsion springs, small torsion springs, and double-bodied torsion springs. Our state-of-the-art CNC machining capabilities allow us to create and manufacture standard and double-bodied torsion springs in multiple wire diameters in either round or rectangular wire. We can also support virtually any bend type or orientation. Materials include steel, brass, bronze, and titanium, as well as specialty alloys. We offer expert engineering support for custom torsion spring requests.Torson sprngs are an mortant component in for example seat belt locks. boot ld springs or backrest springs in cars. The result? Whatever your application, we can help.

Torsion Springs In Vast Range Of Choices

Torsion springs can either have a left-hand or right-hand helix, or even more complicated double torsion springs. They are made to give a force and torque when one leg is turned relative the other.

For different work environment and applications, torsion springs can be made from various materials and forms; by the combinations of different outer diameter, wire size, leg position and number of coils, we can design the optimal solution.

Our catalog torsion springs can be supplied in wire size range from 0.30 to 2.50 millimeter, as well as custom torsion springs are from 0.20 to 4.00 millimeter.For closed coiled helical torsion springs there will be a friction between the coils giving a hysteresis in the torque-angle performance. Normally the torsion spring body is assembled among with a mandrel but also an outer control with a cylindrical housing is possible.

With fixed assembled legs the spring type can work without a coil body control. Tangential legs give the lowest stresses but also radial and axial legs of diferent types are possible. In many cases the strain in the legs must be considered in the design.

The Parameters Of Torsion Springs

The torsion spring is the extreme of the variant spring, from the single torsion spring to the double torsion spring special-shaped torsion spring, and even the deformation of various torsion bars, it can be formed according to the design. Therefore, it is difficult to grasp the necessary information of the torsion spring when designing:

  • Free Length.
  • Controlling Diameter: (A) Outer Diameter, (B) Inner Diameter, (C) Inner Diameter Of The Casing, Or (D) Outer Diameter Of The Round Rod Passing Through.
  • The Wire Size “Wire Diameter”.
  • Materials (Type And Grade).
  • Number Of Turns: (A) Total Turns And (b) Right-Hand Or Left-Hand.
  • Torsion: The Number Of Pounds Deflected To A Certain Angle.
  • Maximum Deflection (Angle From Free Position).
  • The Form Of The End.

Please specify: material diameter (d), outer diameter (D), torsion arm length (L), free height (Lo), and other geometric dimensions, such as guiding moments (T 1 T 2… T j ) and corresponding and Corresponding torsion angle (Ψ)

When the spring is twisted, the material is in a state of tension or shear, such as the torsion calculation mentioned, so the limit of the torsion angle is finally caused by the failure of the material, and the original state cannot be restored when the material is plastically deformed. Therefore, it boils down to the tensile strength and shear strength of the material. Of course, the Von Mises stress calculated by the fourth strength theory is the maximum strength that the material can bear. Combined with the length of the spring, the maximum allowable torsion angle can be calculated.

The Application Of Torsion Springs

A torsion spring is a mechanical part that uses elasticity to work. Generally made of spring steel. It is widely used in computers, electronics, home appliances, cameras, instruments, doors, motorcycles, harvesters, automobiles, etc. The main equipment of production equipment are: digitally controlled multi-function computer spring coiling machine, mechanical automatic coiling machine, spring grinding machine, heat treatment equipment, large-scale hot coil spring production line, and quality testing instruments.
