Machined Spring vs. Wire-Bound

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

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.

Helical’s Flexible Helix Beam

SANTA MARIA, CA. – Helical Products Company’s curved beam “flexure” can be designed and manufactured into a variety of special shapes and forms for use in a variety of diverse applications.

Used as a flexible coupling or u-joint, the “flexure” utilizes its curved beam to transmit torque while compensating for lateral, angular and axial movements. The technology enables designer specified end attachments, such as tangs, clamps, flanges or threaded ends to be integrated into a single, multi-fuctional component.

Helical’s W-Series Coupling

SANTA MARIA, CA.—Helical’s W-Series coupling offers the convenience of metric sizing and fasteners for many designs. These single-piece, flexible couplings from Helical Products Co. compensate for mechanical movement irregularities such as angular and skewed misalignment, parallel offset and axial motion. The unique operating characteristics provide performance benefits such as no maintenance, no backlash, no lubrication, constant rotational velocity, and smooth bearing loads. Helical’s “W” Series couplings are manufactured in outside diameters (OD) of 15mm, 20mm,25mm, 30mm, 40mm and 50 mm. Inch and metric bore sizes are available and may also be combined. All are available in 7075-T6 Aluminum or 17-4PH Stainless Steel materials.

The W-Series can be used in a wide range of applications from driving components with light torque requirements, such as encoders and tachometers, to lead screw and pump applications requiring greater torque.

Helical Launches All-New Website

Helical Products Inc. launches an all new website focused on delivering a vastly improved user experience and key technical information. A new ‘Flexure Facts’ database is easily searchable to find all of the various uses flexible couplings can be applied to, from aerospace to medical applications. The HELI-CAL Flexure is a flexible helix (curved) beam machined from one piece of material into a specific configuration that incorporates special design requirements, performance features or characteristics.

When used as a spring, the flexure provides desired and precise elastic performance in compression, extension, torsion, lateral bending and lateral displacement modes. Used as a flexible coupling or u-joint, the flexure utilizes its curved beam to transmit torque while compensating for lateral, axial, and angular misalignment movements.

A specific 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.

The new site also features new navigation around product specifications, product information, catalog downloads and a wealth of technical information including a new section called ‘Engineer’.
