U-joints: New designs, misalignment ratings, & how to choose suitable features

Standard U-Joints

Free Webinar:  "U-joints: New designs, misalignment ratings, and how to choose suitable features"

Helical Products Company is partnering with Design World on Tuesday, October 17th to present a free webinar, "U-joints: New designs, misalignment ratings, and how to choose suitable features."  Attend this informative webinar to gain insights into Helical Product's new line of standard u-joints and how to specify the correct part number for your application. Universal joints (also called U-joints) transmit rotating power through angles that are much larger than those possible via flexible couplings. No wonder then than U-joints are ubiquitous power-transmission devices used in an array of industrial machines, medical, aerospace and off-highway applications. In this webinar, we explore new options for design engineers that need to employ U-joints — as well as some of the key parameters that dictate which variations are suitable for a given machine axis. Viewing this program you will learn:
  • The basics of U-joint design and their applications
  • How to save time and money with new standard-offering U-joints; how different attachment options (set screws and clamps) allow designers to tailor setups to a given axis
  • How new offerings in U-joints now give engineers access to fast delivery of standard U-joints — in stock and ready to ship within 24 hours — so end customers can build prototypes faster
  • Where standard U-joints are readily available and more cost effective than custom-manufactured product
  • How single-piece U-joints with no moving parts work; where U-joints of different materials excel and where an added Helical flexure can optimize designs
  • The basics of U-joint misalignment ratings and their importance during specifying

In-House Engineering Support

Why is in-house engineering support so important right now?

Engineered in-house Flexible coupling with multiple tooth sensor actuator and index keyDesign World Online recently interviewed Helical Products on our in-house engineering and what changes we are making to continue to lead the industry and keep up with increasing demands. In- house engineering and support is a part of the business model for every coupling manufacturer that wants to remain competitive. Why the increased need over the last few years? We asked Helical Products Co. to help get us up to speed. “We have found that more and more designs are pushing the limits of material capability. In response, we have upgraded our analysis capability to meet the increased demand and improve our first pass results. One element of our design process is to learn as much about our customer’s application as possible in an effort to help them get the best solution that we have to offer. Many times this view from outside the box yields benefits for all of us,” said Yamil Guerra, Helical Products domestic representative from Design Components, Inc. Guerra continues and explains a project in Helical’s recent past that demonstrates the value of the company’s prototype capabilities. “In 2016 Helical introduced a dedicated prototype cell at our plant in Santa Maria, CA. which is used in its entirety for small-batch prototype runs for our customers to rapidly test their new concepts. It has considerably reduced lead times on prototypes giving our customers the R&D advantage to quickly bring their concepts to market. Helical offers engineering consultations free-of-charge both at the customer’s site through our international Representative network, and in-house through our Applications Engineering department.”

How are IoT and additive manufacturing impacting couplings?

How are IoT and additive manufacturing impacting couplings?

The influence of the internet of things, IoT, and additive manufacturing has a long reach and it appears to be expanding. To learn more about how these two technological advances are changing motion systems and the coupling industry in specific, Design World talked to Yamil Guerra, Helical Products domestic representative from Design Components, Inc., to get some answers. Here is what he had to say. I don’t see these methods of automation deployment necessarily changing motion system design as much as increasing the number of opportunities for motion control solutions. As the variety of materials leveraged by additive manufacturing increases, the number of system designs that didn’t have the volume or resources to be built, now become a possibility along with greater affordability of proof of concept hardware. The Industrial Internet of Things (IIoT) has been around for a while (e.g. machine remote access) but together with the Internet of Things making a big splash in consumer products, we’ve entered the era of Big Data, meaning that manufacturers may have more access to direct feedback on their products which in turn may accelerate design improvements in motion design and other areas of a system. We look to see an increase in custom designs with the IoT and additive manufacturing. Additive manufacturing has opened the door to alternative means of material production. However, the technology has to trickle down from high-end manufacturing—say printing the curve profile of a plane’s fuselage in lieu of machining it out of an entire piece of metal—to other industries using older manufacturing methods that are less costly and still provide good results. "Innovative manufacturing practices will pave the way towards any company’s future success." With increasing demands of the US consumer to have products in their hands faster than ever before, an integrated supply chain using new innovative manufacturing practices will pave the way towards any company’s future success. We look forward to what opportunities the internet of things and additive manufacturing brings to us in the future. Read the article from CouplingTips.com here.

Design simplicity in the coupling industry

Is there an increasing demand for design simplicity in the coupling industry?

Greater value for the coupling industry for one piece solutions Design World Magazine recently worked with Yamil Guerra, Helical Products domestic representative from Design Components, Inc. for his take on the coupling industry in 2017. Specifically, they wanted to know if he’s seeing an increased demand for design simplicity or turnkey operation. Here is what he had to say. “Helical’s capability to incorporate what’s at either side of a coupling into a one-piece design gives engineers the possibility to introduce greater efficiencies to any system while decreasing parts-count and inventory. There’s been a steady demand increase in the past couple of years for products that offer simpler designs and greater efficiencies across industries. We have always considered tight integration with customer designs as our competitive advantage in the marketplace, so we perhaps have a more narrow view. But we have had an increase in the number of applications that start with a high level of integration, so either we are doing a better job of getting the word out, or more people are seeing the value of greater integration or both. Because of the nature of our product, to respond to greater demands in integration (simplicity), we have had to focus on faster turnaround in both design, and product delivery, particularly prototypes.” http://www.designworldonline.com/ http://www.couplingtips.com/industry_news/increasing-demand-design-simplicity-coupling-industry/

Flexure Matters

The inspiration for the Helical Flexure came form the observation that one piece "flexured" flexible couplings offered maximum versatility  in terms of form, function and reliability.  Over time, the adaptability of the Heli-cal Flexure in couplings, u-joints and precision machined springs has helped to solve thousands of mechanical misalignment problems.  The flexing qualities of the "flexure" can be customized to compensate for angular and skewed misalignment, parallel offset and axial motion.  All of this can be accomplished while maintaining constant velocity rotation and smooth bearing loads.   Heli-cal Flexures can be designed to customer specifications by simply changing coil dimensions and/or materials.  Each of the following flexures are made from the same material, and have the same outside diameter and length.  These groups of matching colored flexures demonstrate how varying a single characteristic can influence performance.

"Flexure" concept promotes application versatility.

All other things remaining equal, as coil thickness increases, so does torsional stiff and torque load rating.

All other things remaining equal, as coil thickness increases, so does torsional stiff and torque load rating.

    The four red flexures below are identical in outside diameter (OD), inside diameter (ID), length and number of coils.  The only difference is the coil thickness.  Changing this feature affects torque, angularity (bending moment), parallel misalignment (radial load), torsional rate and compressions spring rate.  
As ID increases in otherwise identical flexure, torsional flexibility increases and torque load rating decreases.

As ID increases in otherwise identical flexure, torsional flexibility increases and torque load rating decreases.

All of the green colored flexures are identical with the exception of the inside diameters (ID).  This change affects the torque, bending moment, radial load, torsional rate and compression spring rate.   The only difference between each of the blue colored Heli-cal Flexures is the length of the coil.  Changes in flexure length affect angularity, radial load, torsional rate and compression spring rate.  However, torque capacity remains constant.
With varying coil length, torque capability remains constant while other performances properties change.

With varying coil length, torque capability remains constant while other performances properties change.

The gold Heli-cal Flexures are multi-beam designs.  Multi-beam flexures have two or more coaxial beams.  The difference between a single beam and multi-beam flexure is analogous to the difference between a single and multi-lead screw.  The affect of changing the number of flexure beams, with all other factors remaining constant, will result in changes to all five performance criteria. Variations in the previously mentioned characteristics affect the performance of the flexure in dramatically different ways.  Altering these factors results in performance changes that may be linear, by the square, or by the cube.  
Changing the number of beams significantly changes all performance characteristics.

Changing the number of beams significantly changes all performance characteristics.

Helical engineers manipulate the various attributes of the flexure to create products that meet the performance criteria specified by the customer.  To this point, we have only discussed what can be done by changing the flexure geometry.  This is only the beginning.  When you consider the additional utility that can be achieved by varying the material from which the flexure is made, or integrating custom end attachments into the product design, you realize there is more to this Heli-cal Flexure concept than originally thought.   With all of this versatility, the only missing ingredient is the imagination of the design engineer.  The Heli-cal Flexure is definitely more than a means to connect two shafts; it's a mechanical solution!
