HELI-CAL Machined Spring®
The HELI-CAL Flexure used as a machined spring is a single piece of material machined into a spring con gured as either a compression, extension, torsion, lateral translation or lateral bending spring, to speci c design requirements that provide more precise performance, feature and functions than other more traditional types of springs. Manufactured in a wide range of materials from Titanium, Stainless Steel, MP35N, Inconel, etc. The possibility of integrated attachments and multiple-start coil con gurations (for squareness-under-load) give an endless array of solutions, offering engineers new levels of possibilities in their designs.
The “HELI-CAL Flexure” is an advanced and unique u-joint solution that generally exceeds the capabilities of common u-joint designs. A Helical u-joint is really a Flexure capable of over 5° angular misalignment. It may accommodate up to 90° of angular misalignment in certain circumstances. This type of u-joint will also compensate for axial and parallel misalignment. Replacement with a maintenance free Helical Flexure u-joint can save money, both on initial purchase price and on maintenance costs.
The HELI-CAL Flexure used as a coupling will transmit torque while compensating for lateral, axial, and angular misalignment movements. This technology enables customer speci ed end attachments such as tangs, clamps, anges or threaded ends, to be integrated into a single multifunctional component. Helical offers an extensive line of standard exible couplings and has designed and manufactured over 20,000 custom couplings to maximize value and performance for 1000’s of customers.
In 1958 Helical invented the beam style exible shaft coupling by taking a novel concept and developing the method to generate the versatile HELI-CAL® Flexure into a piece of stainless steel. Over time, the adaptability of the HELI-CAL Flexure in exible couplings, u-joints and machined springs has helped to solve thousands of mechanical misalignment problems.
