High Misalignment, Low Inertia Servo Couplings
The trend in industry to process more material, faster and more efficiently calls for a high torque, high misalignment, low inertia servo coupling, with minimal compromise to torsional stiffness. Stainless steel bellows couplings have the highest torsional stiffness of commercially available flexible couplings, making them the best choice for aggressive servo driven applications. But in cases where the two shafts to be connected are mounted to different bearing surfaces, it can be difficult to maintain the precise alignment tolerances normally required. Utilizing a special, high stiffness bellows and new, high ...
Why Couplings Need Lubrification
In an ideal world, multiple components could be produced in a single piece, or coupled and installed in perfect alignment. However, in the real world, separate components must be brought together and connected on-site. Couplings are required to transmit rotational forces (torque) between two lengths of shaft, and despite the most rigorous attempts, alignment is never perfect. To maximize the life of components such as bearings and shafts, flexibility must be built in to absorb the residual misalignment that remains after all possible adjustments are made. Proper lubrication of couplings is critical to their performance. Figure 1. Types of Misalignment MISALIGNMENT Misalignment can ...

New Jaw Couplings Have Zero Backlash
Zero backlash jaw couplings that are three piece couplings comprised of two hubs and a plastic element are one of Ruland Manufacturing's new products in their coupling line. The Spider, shown below, made of an advanced polyurethane material, provides dampening of impulse loads, minimizing shock to the motor and other sensitive equipment. Available in two durometers, these spiders allow the user to customize the jaw coupling's performance. Selecting a soft spider will give the jaw coupling the greatest dampening characteristics, while a hard spider will provide the greatest torsional stiffness and strength. All spiders are press fit onto a curved jaw profile, ...
Machined Spring Features HELI-CAL Flexure
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.

Helical at Semicon West 2008
The HELI-CAL® Flexible Coupling was conceived in 1958 when George Sabadash developed the concept and method of producing the HELI-CAL Flexure as a single piece flexible coupling. After receiving a strong response from a news release, George realized he had created a useful and needed product. CharliAdded: August 13, 2008 Length: 00:06:20
