Product Description

Stainless Steel Constant Torque Springs for cordless window blinds 


A constant torque spring  is a specially stressed constant force spring traveling between two spools.   The spring is stored on a storage spool and reverse-wound onto an output spool. When released, torque is obtained from the output spool as the spring returns to its natural curvature on the storage spool.
The spring doesn't need to be attached to the storage spool. The spring can be housed in a cavity, eliminating the need for a storage spool altogether. However, friction is then introduced and can change the torque requirements.
The torque produced by a constant torque spring will increase slightly over many turns. Constant torque, or even negative torque, is also possible. Negative gradients of up to 50% can be achieved in certain applications.

Key Features
- Long deflections at nearly constant torque. Positive or limited negative gradients can be achieved
- Minimal intercoil friction and resultant hysteresis as is common in power springs 
- Provides rotary motion directly from output drum or linear displacement through the use of cable and spool

Application : cord retractors , ,drive motor usage
