Characteristic:

The fixed (constant) torque spring (spring) is made of stainless steel. The external force rewinds the mainspring from its natural state to the output wheel (energy storage). When the external force is removed, the spring will return to its natural state. At the same time, a constant torque force (stored elastic force) is generated (released) on the output wheel, so it is called a constant torque generator. strip. Belongs to (a use method in constant force spring)

Advantage:

The advantages of fixed-torque springs compared to power (scroll) springs:

1. The torque will not change due to the increase in the number of revolutions. To

2. There is no limit to the number of available turns, and the design of multi-turn turns mostly adopts a fixed-torque spring. To

3. The number of invalid rotations is small, more energy can be stored, and the efficiency is higher. To

Manufacturing range of fixed torque spring:

The thickness is 0.05~0.85mm, and the width is 2.0~60mm.

Principle of the scene:

When the external force rewinds the constant torsion spring from the natural state to the output wheel, and when the external force is removed, the constant torsion spring will return to the natural state, and at the same time, a constant torsion force is generated on the output wheel. Constant torsion springs can be used in automatic winding, counterweights, power sources, such as power cord automatic recovery devices.

The torsion force of the constant torsion spring will not change due to the increase in the number of turns, and there is no limit to the number of available turns. The fixed torsion spring is often used for functions that require multiple turns. Constant torsion springs can be used in automatic winding, such as cordless curtains.

The constant torsion spring has fewer invalid rotation turns, can store more energy, and has higher efficiency. Constant torsion springs can be applied to power sources, such as clockwork toys.

Composite assembly example:

Compound assembly allows the spring to obtain better (larger) torque in a smaller mechanical space, and can also extend the life of the spring
