SANTA MARIA, CA—The HELI-CAL® Flexure is a flexible helix (curved beam) machined into a unique configuration that incorporates special design requirements, performance features and/or characteristics. The material is basically unlimited.
When used as a spring, the multi-functional flexure provides desired and predictable elastic performance in compression, extension, torsion, lateral bending and lateral translation modes.
One huge advantage of this technology—it enables customer specified end-attachments, such as tangs, clamps, flanges or threaded ends to be integrated into a single multi-functional component.

Things to Consider When Choosing Flexible Shaft Couplings
December 9, 2009 by CouplingTips
Filed under Flexible, Industry News
T.E.A Transmissions says machine designers should consider torsional stiffness, backlash, torque and attachment style when looking to specify flexible shaft couplings.
According to T.E.A Transmissions, its bellows couplings have high torsional stiffness and can be used in any drive system where high levels of motion integrity are essential.
The company says bellow couplings are backlash free and capable of speeds up to 10,000Rpm.
T.E.A Transmission claims helix couplings are manufactured as one piece therefore achieving its flexibility in angular, radial and axial modes. The couplings are capable of speeds up to 8000Rpm.
Bellows and helix couplings are typically used for encoder drives in closed-loop servo system applications.
Variacor Coupling: Built for Flexible Hoses

Filed under Flexible
A new pipe fitting which provides free orientation for hydraulic and pneumatic hoses and tools across a wide range of industrial applications has been introduced by spray nozzle specialists BETE Ltd. The patented Variacor® coupling ensures hosing can be flexible and multi-directional and so brings important benefits to users. For example, the innovative design of the coupling ensures optimum flexibility which results in less wear on hoses and so reduces costs. Also, increased maneuverability of the hose means easier handling for the user while the lower pressure and flow losses compared to conventional couplings, results in a more consistent and improved flow.
The coupling for hydraulic hose applications provides free rotation through 360° for both sides of the fitting while the pneumatic option ensures free rotation of 360° for one side of the fitting and 90° for the other. This 360° / 90° combination also applies to the coupling which is designed for wash guns.
The Variacor coupling is ideal for connecting two runs of rigid pipe or flexible hose, or an end fitting, such as a nozzle or gun. It is a simple, but highly effective means of changing the angle of flow direction, axially between 180° and 90°, with a full 360° swivel at either, or both ends. Adjustments are manual, instant and can be free or lockable. Directional change is achieved by a simple slide turn of the outlet section against the inlet section of the connector.
Neo-Flex Couplings from Advanced Antivibration Components

Filed under Featured, Flexible
New Hyde Park NY — A new series of metric Neo-Flex couplings from Advanced Antivibration Components – AAC feature excellent torsional vibration isolation plus shaft-to-shaft insulation. The center of these couplings, identified as the V50FSR-… (inch) and V50FSRM… (metric) for the Short Series, and V5DFLR-…(inch) and V5DFLRM (metric) for the Long Series, are made from 73 durometer molded neoprene along with 303 stainless steel hubs. They are featured at the AAC eStore where you can order online, request a quote, download CAD models, check stock plus view catalog and technical pages.
They are stocked in two hub styles, conventional pin type hubs which use a set screw for fastening and a Fairloc® version. Fairloc® is a patented integral hub fastener which eliminates marred shafts. The choice of Fairloc® hubs permits frequent phase adjustment, timing and position adjustment while adding positive metal-to-metal fastening strength along both hub sections. The Fairloc® integral hub fastener consists of two slots that are machined into the hub, one radially the other angularly, to create a transverse wedge which remains attached to the solid portion of the hub on one side. The resultant cantilevered clamping section has a tapped hole to accept a cap screw which passes through a clearance hole in the solid portion of the hub, and into a threaded hole in the transverse wedge section. As the screw is tightened, the cantilevered section clamps the shaft securely. The screw can be tightened and released repeatedly without marring the shaft or affecting its torque-transmitting abilities.
They are stocked with both ribbed and smooth style center sections. The ribbed style features an angular misalignment of 5° or 15° (long style) and a parallel offset of 0.25 mm (.010″)(short style) or 0.38 mm (.015″)(long style). The smooth style features an angular misalignment of 1° (short style) or 8° (long style) and a parallel offset of 0.13 mm (.005″)(short style) or 0.25mm (.010″)(long style). They are designed to fit 3 to 6 mm metric shafts or .1200, 1/8, 3/16 and 1/4 inch shafts.

Machined Spring vs. Wire-Bound
June 3, 2009 by CouplingTips
Filed under Flexible
SANTA MARIA, CA—Differences in coil geometry enable machined springs to provide more precise performance, features and functions than can other, more traditional types of springs. There are big differences in performance, reliability, versatility, integrity, and cost effectiveness.
The bottom line is that machined springs offer more functions in a single spring than other more traditional springs, such as wire wound. They also add value, in terms of multi-part integration, time saved in handling, reliability, rates being linear, and dimensions being very precise. They reduce and/or control costs by raising overall productivity.

HELI-CAL® Flexure coupling

Filed under Beam, Flexible
The demands put upon today’s design engineers seem to increase yearly. It is little wonder engineers are reaching for the Rolaids with one hand and the assistance of industry specialists with the other. Clearly the pressure is on engineers to produce designs that create competitive edge.
Designs that provide a competitive edge combine simplicity of manufacture and assembly with durability and quailty in a compact design at a reasonable cost. Every component in an assembly should be evaluated and reevalulated routinely to determine if it could do more and do it better. Another name for its process is “value engineering.”
Each of the integrated, multi-featured products that Helical makes is a story unto itself. The diversity of the features displayed in these parts offers a glimpse into the productivity potential that can be had by using multi featured parts. The integrated, multi-featured part saves assembly time, conserves system space, and by virtue of its single piece name, assures backlash free performance. In almost every case, this means extended life and sizable cost savings to the customer. The only characteristic these parts have in common is the HELI-CAL® Flexure (flexible beam). All other features incorporated in each part were created specifically to customer requirements.

Huco Dynatork, an Altra Industrial Motion company, offers the worlds most comprehensive range of small precision couplings from a single manufacturer. Huco’s precision couplings are ideal for use in high-end servo drives, pulse generators, scanners, X-Y positioning slides, high speed dynamometers, measuring instruments, robotics, machine tools and in many other applications where specific dimensional or performance criteria is required.
Because there is such a wide range of different motion control couplings from which the design engineer can choose, Huco offers a complete Design Guide to coupling performance characteristics on the company’s website.
The website also contains a unique Coupling Selector designers can use as a tool to identify the coupling types that meet their design criteria for angular, radial or axial misalignment, or a combination of all three. The interactive tool helps designers understand whether they need a bellows, membrane, sliding disc or helical beam, or another design.
The Coupling Selector takes the key information provided about the application and presents all the couplings that fit the criteria, with a link to the detailed specification of each coupling. Selection is based upon coupling type (mechanism), dimensions, shaft connections, performance, displacement and other conditions.
