Case Study

Design a torsion spring to lift and hold a storage container lid.

Customer Request:  Design a torsion spring that will lift a storage container lid and hold it at a 60-degree angle.

 

Rockford Spring's engineers were able to use the dimensions and weight of the lid to calculate the torque requirements of a suitable spring.  By refining the rate of the spring using the wire diameter and the number of coils, we were able to achieve a design that opened the lid very smoothly.  The hinge design was also refined to allow enough room for a spring design that could produce the loads required without being overstressed.

 

Prototypes were supplied to the customer that performed as expected and met their design criteria.
