Constant Force Spring Mechanism

Csscfm is one of the earliest constant force mechanisms.

Constant force spring mechanism.

These springs provide rotational energy from the torque output drum d3 or linear motion with the use of a pulley cable or webbing. As the name dictates these mechanisms deliver a near constant force. Constant force spring a tightly rolled ribbon that exerts a nearly constant force as it is unrolled. Easily position a monitor tv keyboard or even an entire workstation exactly where you need it.

2500 4000 13000 and 25000. Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube. When a tensile force acts on it the spiral uncoils to generate a constant output force. A constant force spring is a roll of pre stressedstrip which exerts a nearly constant restraining force to resist uncoiling figures 1 and 2.

Adjust with a touch. The force exerted by the spring is proportional to the distance the spring is stretched or compressed. Each spring is a roll of high yield type 301 stainless steel strip exerting a nearly constant restraining force to resist uncoiling. We can also provide custom constant force springs made to your specification.

C shaped spring constant force mechanism. Constant force springs are thin rolled sheets of metal with a drum or shaft in the center. This is true if the change in coil diameter due to buildup is disregarded. 1 8 to 100 mm.

C shaped spring constant force mechanism csscfm is made of pre stressed material. The force is constant because the change in the radius of curvature is constant. Constructed from a specially stressed constant force spring spiroflex torque motor springs provide high amounts of torque in a small package. Included are spring assemblies constant and variable force pusher springs shelf pushers constant tension springs clock springs and various other constant force products.

Lee spring offers stock constant force springs in four life cycle ranges. 0 05 to 1 0 mm. Gas spring a volume of compressed gas. It usually takes the form of spiral wound on a tight drum as shown in fig.

There is one type of spring that does not obey hooke s law. Ideal spring a notional spring used in physics it has no weight mass or damping losses.
