Constant Torque Springs(B type)

TSMC 'S Constant Torque Springs are constructed from a pre-stressed flat strip material that the form of a tightly wound spiral and is placed on two drums. A constant torque load is developed when the outer end of the spring is attached to another drum as the spring is reverse flexed from the output drum and will returns to its natural curvature on the storage drum.

As its name implies, these Constant torque spring exerts a nearly constant restraining force to resist uncoiling, while offering a large torque in relatively small space requirements. With these characteristics, the constant torque are ideal for a particular area of application with the use of cable, pulley requiring smooth returning, retrieving and counterbalancing, most commonly used for wind-up motors, feeders and conveyors, counterbalance which are utilized in the Aerospace, Medical Devices, Window, Automotive industries...etc.

Features

Type B Characteristics:
1. Constant output torque (zero gradient).
2. High output torque (efficient use of material).
3. No inter coil friction (smooth operation, low hysteresis losses).
4. Low life.
(a) Maximum torque obtained at a life of 2,500 cycles.
(b) Maximum practical life = 35,000 cycles.
5. (a) Sf = 0.025 produces 5,000 cycles life
(b) Sf = 0.010 produces 50,000 cycles life
6. High number of output turns (over 50 turns possible).

Engineering Design
Constant Force Spring

Custom products are a specialty of TSMC (Tech Spring Manufacturing Corp.), as a full service precision manufacturing company, our experienced engineers have extensive knowledge of custom parts, they are always available to assist you to conduct a comprehensive functional analysis of development and gives a feasible solution through our own formula from the preliminary design phase to fabrication that meets your application needs.

There are four critical factors when considering a Constant Force Spring design such as Bore/ shaft (ID/OD), Load, Working height at which the load is applied and Material desired, as well as the other input parameters that contain the wire thickness, wire radial wall, active number of turns, work height, load at work height ... The input data as shown on the left table. And calculation results with spring rate (stiffness), working load (±10%), outer diameter at solid height, Working curve and Life cycles prediction where found in the down table.

Whether you need a standard or custom Constant Force Springs, please send us your application requirement, our experts will hand-select or commend the best solution for your specific needs.
