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.

Constant force springs can be manufactured using the same spring coiling machines used for helical springs. The coiler will have to be modified to accommodate the flat strip of metal that makes up the constant force spring. Posted by vulcan spring. 3m constant force springs are a range of solderless connections for earthing or grounding use on lead and aluminium cable sheaths cable screening tapes or wires and steel or aluminum armour wires.

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. For starters the spring doesn t have to be mounted on a spool. Mounting a constant force spring on a spool.

This type of spring is uniform throughout its length and is coiled into a permanent diameter. One of the most common questions about constant force springs concerns the mounting of the spring on a spool. Conforce springs offer high force output with small space requirements provide long linear reach with minimal force buildup and store power indefinitely when extended. 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.

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. It can be placed in a cavity or on an undersized bushing or pin. It is a pre stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. Aim offers modifications for constant force spring manufacturing as part of their turn key coiling system design services.

Constant force springs the extension type of constant force spring represents the most basic yet most versatile type of constant force spring. 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. Ming tai industrial co ltd. A constant force spring is produced from a flat steel strip and designed to produce constant force just as its name indicates.
