Edited by: Mike Santora, Associate Editor You’ve already accounted for potential misalignments, looked into thermal expansion scenarios and, well, checked to see what coupling was used the last time. So what’s next? Here, we cover some higher-level questions to address when designing the coupling element of your motion system equation. 1. What role does resonant […]
Torque Limiters
Torque limiting coupling with slip detection
Eaton’s torque limiting coupling, the Airflex, increases torque by 25% and provides an automatic slip detection system to help decrease maintenance costs and downtime during operation. Designed to withstand high torque spikes found in grinding mills and heavy duty variable frequency drive applications, the Airflex Torque Limiting Coupling uses automatic reset and re-engage and automatic […]
What is a vibration-damping safety coupling?
Malfunctions happen. And when they do, damage and repair costs follow. Safety couplings are the mechanical connecting elements designed to protect other machine components surrounding a drive system. When a malfunction occurs, safety couplings help keep the damage to a minimum. Safety couplings include torque limiters to handle mechanical overload. In disconnect types, torque limiters […]
Regal introduces mill-drive condition monitoring program
You’ve got to love Ben Franklin. It’s no small irony that, “An ounce of prevention is worth a pound of cure” is attributed to the man whose image is on our $100 bill. Indeed, many Benjamin’s stand to be saved by recognizing system failures before they happen. Regal Power Transmission Solutions is introducing its new […]
New R+W safety coupling handbook now includes the heavy-duty ST series
R+W Coupling Technology has released a new and updated version of its “Safety and Overload Couplings” educational handbook, which now includes the heavy-duty ST torque limiter series. These ST torque limiters are suitable for industrial drive applications with potential for overload, offering disengagement torques from anywhere between 200 and 165,000 Nm. This handbook covers all […]
High-speed shear spacer protects against torque overloads
The Kop-Flex high-speed shear spacer coupling from Emerson Industrial Automation, Florence, Ky., uses a patented double-tube design, precision machining and bearings, and special metal treatments to help provide predictable shear during torque overloads on turbo drivetrains, allowing safe coast down of systems turning at up to 20,000 rpm. Developed to protect gas-turbine-powered generator drives during electrical […]
ETP Power® Shaft Locking Bushing From Zero-Max
ETP Power® keyless shaft locking bushings feature fast mounting with high radial load capacity. They are ideal for locking into position rollers in automated radiator manufacturing lines (photo) as well as gears, pulleys, sprockets and other components in automated machinery. Handling torque ranges from 531 to 10,620 inch lbs. (60 – 1200 Nm), these ETP […]
Zero-Max offers Overload Safety Couplings
Overload safety couplings from Zero-Max are available in special models designed for washdown applications. They clean up easily, won’t corrode, and operate in a wide temperature range. Providing torque limiting and coupling functions in a single, compact unit, these Torq-Tender™ overload safety couplings serve both as a safety device and as a coupling in a […]
Overload safety couplings also limit torque
Zero-Max Torq-Tender Overload Safety couplings protect critical rotating power transmission components from torque overloads. Torq-Tenders serve both as a safety device and as a coupling in a power transmission system. Torq-Tenders can be manufactured for systems requiring frequent washdowns such as food manufacturing and packaging applications. With the addition of an O-ring seal and simple […]
Couplings Target High Corrosion, Long Service Applications
Eaton Corp. developed a new series of ISO 16028 stainless steel quick-disconnect/non-spill couplings incorporating standard anti-extrusion Teflon seals and Viton O-rings. The new FD89 – 2000 Series couplings provide with push-to-connect latching, flush-face valving and incorporate a safety sleeve lock. They are targeted toward applications that require corrosion resistance and long service life, the company said. The […]
