Coil spring Work principle:
Coil spring is also called the power spring , which is made by the steel
ribbon, it can be divided into the natural type power spring and
the prestress force type power spring due to its relaxed shape. The
natural type power spring is made directly by the wrapped steel,
while the prestressed force type power spring will finalize the
shape first, then reverse the direction into a spiral shape, its
shape after spread out just looks like the letter S , hence it is
also known as the S shaped spring.
When we use the coil spring, we need to use a case to confine its outer diameter, the middle
of the spring is connected to the line shaft. Once the line shaft
and the spring do relative rotation by the external force, the
spring will be rolled onto the line shaft and store power. After
the external force disappears, the spring generates torque force to
drive the line shaft, and output the storage power via the line
shaft at the same time.
Comparing under the same specification spring, the prestress force
type can store more torque force of 25%~40% , it can provide more
rotation turns under the same space.
