TND Steel Disc Couplings with updated design for drive applications
Edited by Mike Santora Ringfeder recently updated its TND Series of steel disc couplings, which feature backlash-free torque transmission and excellent positioning accuracy in machines that involve synchronous operation, frequent starts, and stops or reversing operations. Typical drive applications include printing and packaging machines, compressors, pumps, and variable speed drives. Using in-depth finite element analysis […]
Disc couplings for test, measurement, and inspection systems
Ruland disc couplings are zero-backlash, have high torque and torsional stiffness, and can accommodate all forms of misalignment, making them well suited to the requirements of test, measurement, and inspection systems. Single and double disc styles are available, allowing the designer to tailor coupling performance to application requirements. Disc couplings are comprised of two anodized […]
Ringfeder’s TND steel disc couplings with updated design
RINGFEDER announces an updated version of its proven TND Series of steel disc couplings, which feature backlash-free torque transmission and excellent positioning accuracy in machines that involve synchronous operation, frequent starts, and stops or reversing operations. Typical drive applications include printing and packaging machines, compressors, pumps, and variable speed drives. Using in-depth finite element analysis […]
Ringfeder shrink discs
The high-quality original from the world market leader: RINGFEDER Shrink Discs are flange-shaped, friction-locked shaft-hub-connections and the more powerful and reliable alternative to conventional shrink fits, wedge, keyway, or polygonal connections. In contrast to internal locking devices, e.g. locking assemblies, the pressure is applied from the outside to the hollow shaft or hub, thus creating […]
Disc couplings for higher misalignment servo applications
When precision machine drives are assembled without mounting pilots between the servo motor/gearbox and driven equipment, shaft misalignment becomes a key consideration in coupling selection. Most precision couplings are designed to compensate for a parallel shaft misalignment of between 0.1-0.2mm, which is perfect for piloted interfaces. When the connected components are mounted to different surfaces, […]
Hexelus GTR family of heavy duty, torsionally rigid disk couplings
Designed to suit applications where high reliability, precision, and an optimum weight/power ratio is required; ideally suited for applications with high speeds and power. This coupling is composed of three main items: the two fully turned steel hubs and a single or double disc pack in 304 stainless steel. Larger and more rigid than “typical” […]
Customizing torsionally rigid disc couplings with shrink disc for wind turbines
Couplings play a critical role in energy equipment — especially wind turbines. These durable components, which connect the gearbox to the generator, ensure the rotor blade system is operating as it should. Without the right coupling, a wind turbine can’t function properly, driving up maintenance costs and downtime. These scenarios are not welcome—especially since any […]
Rexnord XTSRLS Thomas disc couplings
Thomas XTSRLS couplings are full-floating shaft couplings designed for applications with relatively long distances between connected equipment, either horizontally or vertically. XTSRLS couplings are a suitable choice when shaft spacing exceeds the maximum length of standard fully machined spacer designs (XTSR52/ XTSR71). Common applications include vertical pumps, fans & blowers, compressors, and paper machines. XTSRLS52: Welded […]
End-to-end coupling solutions for cranes and hoists
When it comes to gearbox coupling applications, some misalignment is unavoidable. This is especially true for cranes and hoists due to their very heavy loads. Fortunately, you can manage misalignment by choosing the right couplings. Here are some of your options specifically for cranes and hoists. Connecting the Gearbox and Cable Drum Recommended for crane-lifting […]
