Torsional deflection introduces a unique effect on gear couplings. Because the deflection and distortion effects on a coupling are all interdependent, it can be difficult to discuss them in isolation. In gear couplings, torsional deflection creates a varying load across the face of the gear(s). If this load distribution is uniform, then the torsional deflection […]

IoT and couplings: fairytale or the future?
by Mike Santora, Associate Editor Couplings connect driving elements to driven elements. But is there a connection beyond the mechanical? We asked four industry experts to give us their take on connectivity, the Internet of Things and its potential impact on the couplings industry. To hear its supporters speak of it, the fully realized Industry […]
What do you know about Gear Couplings?
Though one may not think of gears as being flexible, gear couplings are very much considered to be a flexible coupling. A gear coupling is a mechanical device designed to transmit torque between two shafts that are not collinear. The coupling typically consists of two flexible joints, one fixed to each shaft. These joints are […]
The reinvention of the gear coupling
by Michael Jermann, Assistant Editor A new development in gear couplings allows downsizing without loss of performance. Gear couplings handle motion functions that other coupling types are unable to, or that need modifications and de-rating to function. Plus, they can be modified for shear pin service, floating shaft type, vertical applications, electrical isolation, limited end […]
HercuFlex gear couplings improve performance while maintaining interchangeability
The HercuFlex series of gear couplings from Lovejoy were designed with a large bore capacity, high nominal torque ratings and misalignment capabilities of 1.5° per gear mesh. Yet the couplings still meet the AGMA flange standards (allowing interchangeability with existing flanges gear couplings) and come available in AGMA sizes 1 to 30. HercuFlex consists of […]
Large hybrid couplings manage torsional vibration in drivetrains
Featuring extremely high torque ratings and torsional vibration management, Kop-Flexx Max-C WB hybrid couplings from Emerson Power Transmission, Florence, Ky., combine a maintenance-free, non-lubricated Max-C resilient coupling half with a lightweight diaphragm, disc or high-performance gear coupling half, depending on the application. They are best suited for drivetrains powered by synchronous motors, variable-frequency drives, […]
GAM Gear offers two-week delivery for gear reducers
GAM Gear announces a new two-week standard delivery program for the PE series of inline planetary gear reducers. The PE series has precision gears and robust dual output bearings making it a great option for most servo and stepper motor applications where performance and durability are required. The delivery program covers popular ratios from the […]
Clever engineering renews wrecked steel mill coupling
By Dan Kocel, Emerson Power Transmission Solutions When the bore on the rigid half of a high-torque steel mill coupling was badly galled during a maintenance teardown, an East Chicago, Indiana, mill put the damaged part in the plant’s bone yard. However, engineers at Kop-Flex® – part of the Power Transmission Solutions business of Emerson […]
NS2 Couplings
The NS2 Series non-spill couplings create fast, safe, and virtually leak-free fluid line connections. For printing and ink management, analytical instrumentation, electronic cooling, and other applications, the couplings transfer large amounts of fluid, yet they physically take up little space. The couplings’ use a twist-to-connect locking mechanism. Double-sided non-spill shutoff valves add safety and convenience. […]
