Double Bodied Torsion Springs Manufacturing

Manufacturer of Double Torsion Springs (Double Bodied Torsion Springs)

Katy Spring manufactures single, double and spiral springs, which are torsion springs with a helical shape. These helical springs exert a torque or rotary force and are subject to bending stresses.

Double torsion springs (double body torsion springs) are comprised of a right-hand and a left-hand coil section which are two sets of coils: one wound clockwise, the other counterclockwise. It combines these two separate torsion springs into one unit by bridging them at the middle. Both sides work in parallel to double the torque output. Double torsion springs are designed using single bodied torsion spring methods, but the rate for a double torsion spring is equal to the sum of the rates for each component. In other words, double torsion springs have rates four times those of single-bodied types for wire diameter, coil diameter and wire length.

Double bodied torsion springs should be designed to coil out from the center rather than in from the ends so that they can be rotated in angular deflection. Double body torsion springs are found in automobile door systems and are commonly used as couplings between concentric shafts such as motor and pump assemblies.

Applications include:

  • Major household appliances
  • Medical devices
  • Military devices
  • Aerospace devices
  • And more

Ordering Custom Double Torsion Springs

The basic information needed by Katy Spring is material, wire size, free length, number of coils, travel, diameter, end types, finish, works over, works in, and maximum solid height. It is crucial to carefully consider the space allotted to ensure that the spring will function properly and avoid costly design changes. Katy Spring can assist customers in determining design parameters if only partial data is available.
