Product Description
TEMB has been specialized in spring for 20 years. With 15 computer coiling machines, 13 heat-treatment furnaces, 16 spring grinding machines, 6 chamfering machines, 8 setting machines, 5 shot-blasting machines, 1 full automatic load sorting machine, 8 fatigue machines, 6 tension and compression testing machines, TEMB can produce all kinds of springs with diameter 0.2~12.0mm, annual capacity 80 million pcs.
We have established long and friendly cooperation relationship with high level steel manufacturers at home and abroad, ensuring the reliable raw material quality, such as SUMITOMO and Suzuki Garphyttan from Japan, KISWIRE from Korea, and SINOSTEEL from China.
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

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.

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 springs in a dual mass flywheel.
The arc spring is suitable for static and quasi-static as well as dynamic applications. Examples include:
Dynamic applications:
Dual mass flywheel
Torque converter
Arc spring clutch
Belt tensioners, pulley decouplers
