Constant Torque Spring Motor For Cordless Blinds

The cordless blinds spring, which belongs to a constant torque spring motor, is the main components in spring hoists. Stable and reliable reset function and has a long service life.

The working principle of curtain torsion spring is mainly based on two principles: elastic deformation and resilience. When the curtain torsion spring is subjected to external forces, it will be deformed. Once the force is removed, the spring will return to its original shape. This deformation and restoration process can be used to control the opening and closing of the curtain.

The materials of  cordless blinds spring mainly include stainless steel, carbon spring steel wire, alloy spring steel wire, stainless steel wire, oil quenching and tempering chromium vanadium spring steel wire, oil quenching and tempering carbon spring steel wire, oil quenching and tempering silicon manganese alloy spring steel wire, oil quenching and tempering Tempered chrome-silicon alloy spring steel wire, etc.

The material usually used is high-quality stainless steel, which can meet the needs of customers for various styles of roller spring.

Advantages of curtain torque springs include:

• Good fatigue resistance: the curtain torsion spring has the ability to resist fatigue damage under long-term vibration and alternating stress, which can ensure the normal use of the curtain.
• Strong ability of processing and bearing impact load: Curtain torsion spring has sufficient plasticity and toughness, which can meet the needs of curtain when forming and bearing certain impact load.

• High elastic limit: The curtain torsion spring has a high elastic limit or yield limit and a high yield ratio, which can ensure that the spring has high elasticity, thereby improving the service life of the curtain.

• Easy to maintain and replace: The maintenance of the curtain torsion spring is relatively simple. If the spring is damaged or aged, it can be easily replaced, and the maintenance cost is low.
