Couplings for higher speed applications

November 4, 2011 By Leslie Langnau Leave a Comment

ServoClass Couplings feature high torsional stiffness, zero backlash and low hysteresis to ensure repeatable precise positioning at speeds up to 10,000 rpm. Their robust design ensures precise system operation in automated 24/7 applications. That is especially true where stresses occur at increased speeds in a servo system. Designed with 304 stainless steel disc packs and […]

High-Torque Disk Couplings Resist Fretting

May 26, 2010 By Kathie Zipp Leave a Comment

Torsiflex disk couplings are torsionally stiff and backlash-free, incorporating an anti-flail feature. The couplings also withstand significant levels of misalignment without loss of operating performance. The design drives in friction, rather than shear, to the disc coupling by using large aircraft-quality bolts on the disk hubs. As a result, the pack of blades in the […]

Six factors to remember about couplings in a motion system

March 25, 2010 By Leslie Langnau Leave a Comment

Updated May 2019 || Physical values such as torque, torsional rigidity, spring stiffness, moment of inertia, imbalance, and zero-backlash play a major role in coupling design. Here are a few facts to keep in mind when you design your motion system. 1. Torque (Nm) is the product of an acting force and the effective length […]

Tips to simplify coupling selection

August 19, 2009 By CouplingTipsAdmin Leave a Comment

For a coupling in a servo application to work properly, you need to satisfy a number of application factors including: torque, shaft misalignment, stiffness, speed, and space requirements. Here’s a look at the available types of servo couplings and what you need to consider for each of them during the selection process. Beam couplings Beam […]
