The HELI-CAL Machined Spring® provides very repeatable and linear, axial spring rates because of the absence of residual stresses often associated with traditional wire wound springs. A significant advantage of the HELI-CAL Machined Spring is the ability to provide multiple-start Flexure (coil) configurations. Using the multi-start configuration (normally Double or Triple Start) the unresolved moments common to single-start springs will prevent tipping or the application of side loads during compression or extension. One additional benefit of the multi-start coil configuration is it provides a level of system redundancy because more than one coil is transmitting the load. Another feature of the HELI-CAL Machined Spring is combining a right-hand and left-hand Flexure in a single piece to prevent rotation that many types of springs exhibit during compression and extension. The ability to incorporate custom machined features as part of a single piece elastic component makes the HELI-CAL Machined Spring the perfect solution for today’s demanding applications.
