A bellows coupling is a type of flexible coupling that features high torsional stiffness, low moment of inertia, and minimal restoring forces under misalignment. These characteristics make bellows couplings suitable for motion systems that require a high degree of accuracy, repeatability. Most bellows couplings use a stainless steel tube, which has been hydroformed to create […]
What do you know about Beam Couplings?
Most couplings can be categorized as one of two types, rigid and flexible. Rigid couplings are used in applications where proper alignment is essential, while flexible couplings, such as beam couplings, are suited for applications where there is some acceptable misalignment. A beam coupling, sometimes called a helical coupling, consists of a single piece of […]
Rexnord to aquire Indian disc coupling maker
Rexnord has entered into an agreement to acquire Euroflex Transmissions. Euroflex is a supplier of high performance disc couplings, used in power generation, gas compression, and industrial process machinery applications. Euroflex serves global original equipment manufacturers (OEMs) from its base in Hyderabad, India, and has annual revenues of approximately $16 million (USD). Closing is anticipated […]
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 […]
Jaw coupling overview – features, benefits & design basics
Jaw couplings are a general, all-purpose industrial power transmission device that operates in a range of temperatures, handles angular misalignment and the accompanying reactionary loads, resists chemicals and has good speed and dampening capabilities. A basic jaw coupling is made of three parts: two hubs, generally bored to a clearance fit tolerance, and an elastomeric […]
Non-Metallic expansion/deflection coupling improves safety while reducing installation time
The non-metallic expansion/deflection coupling from T&B Fittings improves safety and reduces installation time for joining rigid polyvinylchloride (PVC) conduit that is subject to movement in any direction at structural joints. Its design makes the coupling up to five times faster to install, while its versatility enables a five-to-one reduction in stock keeping units (SKUs). The coupling […]
Step-Flex couplings reduce resonance in stepper motor ball screw assemblies
Mechanical resonance in motion systems can cause, not only unpleasant noise, but can lead to oscillations in the machine that reduce the positional accuracy of the system. This oscillation can also cause the system to take too long to find its correct positioning and further degrade performance. In rare cases where extreme oscillation is present, […]
Compact servo couplings provide backlash-free torque transmission
The ROBA-DS servo couplings with split clamping hubs allow easy and fast installation, even in difficult ambient conditions. They are suitable for large shaft distances and in all applications, in which the drive aggregates must not be moved any more. These couplings are made of steel and high-strength aluminum alloys, which forms the basis for […]
Kop-Flex service program recertifies used couplings to API 671 standard
Emerson’s Power Transmission Solutions introduced a new program for restoring used high-performance couplings to like-new condition, certified to API 671, with a full original factory warranty. Ideal for high-speed (>1,800 rpm) couplings used on turbomachinery, compressors, pumps and marine drivetrains, the Kop-Flex recertification program is a low cost alternative to replacement of a coupling, for […]
Emerson releases asset managment tool for critical drivetrain couplings
Emerson’s Power Transmission Solutions has released the industry’s first online tool for tracking the location, life history and latest revision drawings and installation instructions for all critical drivetrain couplings owned by customers, whether installed or in spares inventory. Developed by Emerson’s Kop-Flex business unit, the web-based tool, known as the Asset Management Program (AMP) for […]
