What is a Multi Start Flexure
A multi-start flexure has equally spaced coils manufactured into the part, such that they simultaneously carry the loads applied to the part.
In torsion springs, using a multi-start spring allows for a higher torsional stiffness to be obtained and greater torque to be transmitted.
For couplings, as well, using a multi-start flexure allows for a higher torsional stiffness and greater torque, without as significant an increase in radial loads that a single-start flexure would impose.
For compression and extension springs, a multi-start flexure provides the benefit of resolving the moment at the ends of the part during loading, allowing the ends of the part to remain parallel during deflection.
Another benefit that a multi-start flexure has, is to provide redundancy if one of the coils fails during operation. The spring may continue to operate, at a reduced level of performance, until it can be replaced.
A New Angle on U-Joints
The HELI-CAL® “Flexure” is an advanced and unique u-joint solution that generally exceeds the capabilities of common u-joint designs. A HELI-CAL® u-joint is really a flexure capable of over 5°of 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.
Generate Only Enhancement Program
As the old adage tells us, a chain is only as strong as its weakest link. While this bit of wisdom applies to a wide variety of situations, it rings particularly true for components in an engineered system. Each part has a role to play and an essential burden to bear. From medical machinery components to aerospace applications, one common weakness can create critical failure: EXCESSIVE RIGIDITY. A universal problem calls for a universal solution; one that provides essential flexibility for all of your precisely designed components. This solution is our proprietary Heli-Cal® Flexure technology, implemented through our unique Generate Only product enhancement program. Our Flexure helps prevent premature component wear, likelihood of damage, motor seizure, bearing failure, elimination of vibration failures, compensation for coefficient linear expansion, and many other benefits.
