Many variations of constant force spring are possible over and above the simple increase in size, thickness, diameter etc.
com)-- Constant Force Springs from Lee Spring offer an excellent mechanism for applications where a constant load is required.
Lee Spring offer constant force springs in four Life Cycle ranges where each spring is a roll of high yield Type 301 Stainless Steel strip exerting a nearly constant restraining force to resist uncoiling.
Typically stainless steel Type 301 is selected, but high-carbon steel, Inconel and other materials are also suitable for constant force springs.
Considerable flexibility is possible with constant force springs because the load capacity can be varied by using different mounting configurations such as cavity mounts, multiple spring mounts, etc.
Constant Force Spring Serves As Simple Solution For Weighty Problems
A constant force spring can remove the effect of gravity and counter-balance the weight of heavy machine heads so that smaller motors can be used for precise movement at reduced costs.
The spring motor version of the constant force spring can be used in hose and cable rewinding mechanisms, in-flight refueling systems, and vacuum cleaners.
