The versatility of the HELI-CAL Flexure means unprecedented design opportunities for you. We invite you to peruse this sampling of case histories… and then imagine the HELI-CAL Flexure’s application possibilities for your most challenging designs. Helical Custom Couplings: Eliminate Axial End Play Eliminate Backlash and Overtravel Accommodate Misalignments Reflect Close-tolerance Precision Adapt to Low Inertia […]

Helical’s 17-4PH stainless steel flexible couplings (couplers) are suitable when high strength, fatigue resistance and high torsional 17-4PH Stainless Steel H, W and MC Series couplingsstiffness are called for in an application. When compared to both 303 stainless steel and 7075-T6 aluminum, 17-4PH provides twice the torque and can operate up to 600F. Helical couplings […]

The Challenge The customer wished to enhance their line of leadscrew assemblies by being able to offer a flexible coupling. This flexible coupling would allow the customer to present a more complete package with their product. They envisioned using our standard flexible coupling AC075 with a 10-32 threaded bore. The Solution As you can see, […]

The Challenge A company that produces “Vibration Monitoring Instrumentation for Rotating Machines” asked Helical to help them devise a unit that would act similar to an encoder. They wished to incorporate an incremental counting method into this unit. The customer was using a rubber type coupling and modifying it to use in measuring phase position […]

Coupling Tips

By Joyce Laird, contributing editor Understanding design challenges Most of the couplings on the market today are either partially, or entirely, made of metal. Since metal is such a good electrical conductor it can be a challenge for the design engineer to find a suitable product to serve as a flexible coupling for transmitting torque […]

This webinar was recorded on Tuesday, July 19, 2016. Watch the on demand webinar. Most engineers are familiar with traditional wire wound (coiled) springs, but in this webinar attendees will learn about a viable alternative known as “machined springs”.  Based on the whitepaper “Choosing between Machined and Wire Wound Springs”, the webinar will review differences…

Helical Products Company, part of the MW Industries family of companies, announces their new prototype cell dedicated to quickly provide new designs for test and evaluation reducing the lead time for prototypes by over 50%. “For the past 40 years we have been manufacturing custom couplings, u-joints and machined spring prototypes and the lead times…

Helical shared in the donation of $120,000 to the Machine Technology Program at Allan Hancock Community College. The program provides students with a full range of machining courses. Students learn skills of machine technology and using Computer Numerical Control (CNC) machines. Many of these techniques are critical when making flexible couplings and machined springs both […]

By Laura Carrabine, Senior Editor Many of the design requirements for NASA’s latest Mars explorer Curiosity are related to the Sample Acquisition and Sample Processing and Handling (SASPaH) subsystem that will gather soil samples from Mars’ surface. NASA’s Jet Propulsion Lab (JPL) collaborated with Helical Products Company engineers to develop flexible couplings and machined springs…

Machined springs offer several benefits not available with wire wound springs, such as integrating multiple features into one piece. Gary Boehm will cover the differences between machined and wire wound springs, features and benefits, as well as application tips, including tips for using them in torsion and wrap spring clutch applications. You will learn the…

Custom “machined” springs let you integrate multiple features into one piece. These unique springs can be designed specifically to address requirements for rate, reactions at desired deflections, combined rates, modal properties, weight and inertial limits. You can specify end attachments such as tangs, clamps, flanges, or threaded ends can be integrated into the single multi-functional…

By Gary L Boehm Gary L Boehm, PE Helical Products Company, Inc. Wire springs appeared early in the Industrial Revolution and established their value immediately. The basic concept has not changed much, though there have been enhancements in materials and manufacturing. Typically, spring wire is coiled hot or cold with ends configured within the limits…
