The shape of the clockwork spring

There are many ways to the shape of the clockwork spring, here we introduce several common:

Spiral: this is a mechanical device that is commonly used in hair play spring, as a source of power.

S-shaped: all the clocks and watches the clockwork spring, using as a source of power.

Knuckle fixed shape: due to the friction between the ring is large, the output torque decreased a lot, and torque curve is not smooth, so in precision and particularly important institutions should not adopt the fixed method.

Pin type fixed: the fixed pin type between rigid fixation and hinged fixation, friction between the ring is still large, but lower than the fixed hinge type, often used for large size clockwork spring.

Fixed: V V fixed can make the outer side has certain death like radial movement, the friction between the ring from the previous two small, in addition, the structure is simple, common in smaller clockwork spring, its disadvantage is bend is very easy to fracture.
