OEM Flexible Factory Custom Heavy Duty Industrial Spiral Torsion Spring
Torsion Spring is a complex design principle among all types of
springs and the type change is quite lively, so the theory involved
in the design is the most complicated. Each ring or close or
separate around, can be suitable for torsion load (at right angles
to the spring axis). The end of the spring can be wound into a hook
or straight torsion arm.
Torsion springs belong to the category of spiral springs. Torsional
springs can store and release angular energy or statically hold a
device by rotating a moment arm about the central axis of the
spring body. The end of the torsion spring is fixed to the other
components, and as the other components rotate around the center of
the spring, the spring pulls them back to their initial position,
generating torque or rotational force.
Such springs are usually close-fitting, but the springs are spaced
to reduce friction. They exert resistance to rotation or rotational
forces. According to the application requirements, the design of
torsion spring rotation (clockwise or counterclockwise), so as to
determine the spring rotation.
A torsion spring is a mechanical part that uses elasticity to work.
Usually made of spring steel. It is widely used in computer,
electronics, home appliances, cameras, instruments, doors,
motorcycles, harvesters, automobiles, and other industries to
control the movement of machine parts, ease impact or vibration,
storage energy, measure the size of force and so on!
