Wide Variety of Standard & Custom Torsion Springs

Torsion springs are helical springs that exert a rotary force. The ends of a these springs are connected to other components. As the components start to rotate around the center of the spring, the torsion spring exerts an equal force to push them back to their initial position. These springs are subjected to bending stress instead of torsional stress, and are capable of storing and releasing angular energy. They can hold a mechanism in place statically by deflecting the legs by the center-line axis of its body. CISI provides regular custom torsion springs, as well as heavy duty torsion springs to suit your design requirements.

Specifications:

Following are the specifications of torsion springs:

Parameters:

Here are some of the parameters of torsion springs:

1. Outer Diameter: The outer diameter of the spring is specified when it is required to fit into a circular hole with enough exterior clearance for operating freely. It is also specified in case of any outer housing clearance issues.
2. Inner Diameter: The inner diameter of the spring is specified if the spring is required to slip over a mandrel with necessary clearance for operating freely.
3. Spring Length: The spring length is the length of a spring coil.
4. Wire Diameter: Wire diameter is the diameter of a spring wire.

Performance factors:

1. Spring Rate: Spring rate is the angular return torque provided per unit of angular displacement.
2. Maximum Deflection: Maximum deflection is the maximum rated angular deflection of spring before damage.
3. Wind Specifications: The wind of the spring can be right hand, left hand, or double torsion.

• Left Hand Wind: Wound in a left-hand configuration.
• Right Hand Wind: Wound in a right-hand configuration.
• Double Torsion Wind: It refers to one left hand and one right hand wind on the same spring, typically with the unwound section in between the winds. The two legs of the spring are on the same side.

Configurations

Our helical torsion springs are designed for rotary actuation. These springs provide an angular return force too. These springs are offered in various leg configurations, which enable their attachment in different ways. The leg specifications to consider for torsion springs include leg end style, leg angle, and equal leg length.

Helical torsion springs that are parallel or straight on the same side have 0° leg angle, and their angle increases in the direction of unwinding. Some of the leading leg end styles include the following:

• Straight Torsion
• Straight Offset
• Hinged
• Short Hook Ends

Torsion springs can be hooked, bent, twisted, and looped to meet your application requirements. We provide torsion springs in a choice of 360°, 300°, 270°, 210°, 180°, 120°, 90°, and free leg position.

Benefits of Torsion Springs:

Some of the major benefits of these springs are as follows:

• Durable
• Easy to adjust
• Relatively small
• Great automatic levelling

Applications:

These types of springs are commonly used in:

• Clothes pins
• Clipboards
• Swing-down tailgates
• Garage doors
• Hinges
• Counterbalances
• Lever return applications
