Flexible vs rigid couplings: Part 1
In this first installment of a weekly 3-part series on flexible vs rigid couplings, R+W America’s Andy Lechner shares his insight into the best options for different applications. This excerpt was taken from Lechner’s presentation during the Design World Webinar, Flexible vs Rigid Couplings. Quick disclaimer, R&W is not a manufacturer of rigid couplings. Obviously, […]
Motion systems application examples: Couplings
By Mike Santora Couplings are simple yet precisely engineered devices that connect shafts to transmit torque and compensate for misalignments. But many variations of coupling designs exist to complement machine dynamics and meet specific application criteria. Couplings are either torsionally rigid or flexible. Flexible couplings compensate for misalignments, while rigid designs handle drive components already […]
What is a Rzeppa joint?
While working as an engineer for Ford Motor company, Alfred Hans Rzeppa created his constant velocity joint in 1926 and patented it the following year. The Rzeppa joint is a specific type of constant velocity joint—the ball and socket design involves 6 balls working with inner and outer races to transmit constant velocity torque from […]
Electrically isolated, zero backlash couplings
Control-Flex couplings from Zero-Max are designed for encoder applications. Control-Flex couplings help minimize a system’s reaction forces for more precise and repeatable operation and longer life. Designed with a parallel linkage-style flexible disc, Control-Flex provides radial flexibility to reduce reaction forces such as side loads on shaft bearings and seals that can be caused by shaft […]
What do you know about Elastomeric Couplings?
Elastomeric couplings are a form of flexible coupling that uses an insert made of an elastomeric polymer to help transmit torque. The design of elastomeric couplings means that the elastic material is meant to wear out before any metal components. This not only saves time and money on maintenance but also means that the couplings […]
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 […]
Flexible Couplings-Common Mistakes in Assembly and Maintenance
By: Stan Riddle, VibrAlign In my job, I teach shaft alignment training to over 500 people per year, in dozens of facilities-everything from manufacturing, to mining, to energy, to municipalities. All of these facilities have one thing in common-they use the same types of couplings. And many of them fail before their time. This article […]
Zero-Max CD Couplings add Electrical Insulation Protection to Mechanical Components
Motion system designers have a new option to arrest electrical current. In addition to their primary function, Zero-Max CD couplings are designed with composite flex elements that are non-conductive. The flex element designed into the couplings provides electrical insulation while protecting mechanical components from system overloads. CD Couplings do not pass electrical current through the […]
Pick the right coupling for each high tech application
Selecting the right coupling for your application is critical to system safety and reliability, says Ruland Manufacturing Co. Inc., Marlborough, Mass., which manufactures a diverse couplings product line while providing technical support and application experience. Ruland’s coupling line includes rigid couplings with precision honed bores and five types of zero-backlash couplings: beam, bellows, disc, jaw, […]
