The arc spring (also known as - bow spring, curved spring, circular
spring or "banana" spring) is a special form of coil spring which
was originally developed for use in the dual-mass flywheel of
internal combustion engine drive trains. The term "arc spring" is
used to describe pre-curved or arc-shaped helical compression
springs. They have an arc-shaped coil axis. Function Like other
technical springs, arc springs are based on the fundamental
principle of storing mechanical work in the form of potential
energy and the ability to release this energy again. The force is
applied through the ends of the spring. A torque can be transmitted
around an axis via the force directed along this helical axis and
the lever arm to the system center point. The wire of the arc
spring is mainly subjected to torsional stress. Support Arc spring

single-stage arc spring supported by a sliding shell in a
torque-angle characteristic curve. An arc spring requires suitable
support to transmit torque. The support is usually provided from
the outside in the form of an arcuate channel (sliding shell) or
radially shaped support plates. This prevents buckling of the arc
spring. Another result of this support is a hysteresis between the
loading and unloading curves in the characteristic curve. This
results from the friction of the spring on the radial support and
is an intended effect to achieve damping in the system. Arc spring
systems As with compression springs, spring systems can also be
used for arc springs. The main designs are series and parallel
connection. With these, single-stage or multi-stage spring
characteristics can be achieved. In order to make optimum use of
the available space, systems consisting of inner and outer arc
springs are often used. Representation of the friction hysteresis
of a two-stage arc spring supported by a sliding shell in a
torque-angle characteristic curve. In addition, the spring
characteristic can be influenced by other parameters such as the
cross-sectional geometry of the wire, the coil diameter or the
number of coils. Applications Schematic representation of bow
