Constant Force Spring Uses

These springs are ideal for a wide variety of uses where constant force tension springs are needed including applications requiring smooth extension and retraction.

Constant force spring uses.

It is a pre stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. Constant force springs the extension type of constant force spring represents the most basic yet most versatile type of constant force spring. One of the most common questions about constant force springs concerns the mounting of the spring on a spool. The law is named after 17th century british physicist robert.

This type of spring is uniform throughout its length and is coiled into a permanent diameter. Is professional manufacturer of steel strip spring since 1966 from taiwan. Constant force springs can be manufactured using the same spring coiling machines used for helical springs. Ming tai industrial co ltd.

For starters the spring doesn t have to be mounted on a spool. Hooke s law is a law of physics that states that the force f needed to extend or compress a spring by some distance x scales linearly with respect to that distance that is where k is a constant factor characteristic of the spring i e its stiffness and x is small compared to the total possible deformation of the spring. Aim offers modifications for constant force spring manufacturing as part of their turn key coiling system design services. A constant force spring is produced from a flat steel strip and designed to produce constant force just as its name indicates.

Posted by vulcan spring. Mounting a constant force spring on a spool. The variables of the equation are. It can be placed in a cavity or on an undersized bushing or pin.

The minus sign shows that this force is in the opposite direction of the force that s stretching or compressing the spring. When extended the spring will recoil with consistent force. F which represents force k which is called the spring constant and measures how stiff and strong the spring is and x is the distance the spring is stretched or compressed away from its equilibrium or rest position. An ideal constant force spring is a spring for which the force it exerts over its range of motion is a constant that is it does not obey hooke s law in reality constant force springs do not provide a truly constant force and are constructed from materials which do obey hooke s law.
