Rigid couplings for power transmission applications
Torsionally stiff rigid couplings are best used on shafts that are already in proper alignment, so are well-suited to pump, mixer, drive shafts, and other power transmission applications. Stafford Manufacturing Corp., Wilmington, Mass., offers a full line of rigid couplings in a variety of configurations and sizes for connecting these types of components. Rigid couplings […]
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, […]
Rigid couplings join variety of unsupported shafts
Line of rigid shaft couplings come in a range of types, sizes, and materials for joining unsupported shafts in applications ranging from delicate instruments to large mixers and pumps. Stafford Rigid Shaft Couplings come in one-, two-, and three-piece designs, with or without keyways, in sizes ranging from 1/8 in. to 4 in. I.D. Featuring […]
Tests measure differences among Falk Steelflex, Lovejoy, and Dodge grid couplings
Recent third party testing was conducted on Falk Steelflex, Lovejoy and Dodge grid couplings to quantify differences in performance and durability, and understand the affects on coupling performance when one branded part is interchanged with another. The tests prove Falk Steelflex grid couplings offer the lowest total cost of ownership by standing up to impact […]
Couplings for higher speed applications
ServoClass Couplings feature high torsional stiffness, zero backlash and low hysteresis to ensure repeatable precise positioning at speeds up to 10,000 rpm. Their robust design ensures precise system operation in automated 24/7 applications. That is especially true where stresses occur at increased speeds in a servo system. Designed with 304 stainless steel disc packs and […]
Miniature couplings for medical applications
These miniature rigid couplings handle a variety of medical device applications, including test and measurement systems, imaging, patient positioning, and liquid handling such as chromatography. Rigid couplings are zero-backlash, torsionally stiff, and have high torque capacity. They should be used when shaft misalignment is neither present nor desired, with the rigid coupling often used to […]
VULKAN Couplings unveils New Integrated Shaft Coupling Design
VULKAN Couplings (www.vulkan.com) has unveiled a new innovation of the Rato DS coupling that is directly connected to a composite shaft. Aside from being a torsional coupling, the combination of high radial stiffness and low bending and axial stiffness makes the Rato DS ideal to work as an integrated misalignment coupling when it is rigidly […]
Stafford Large Bore Shaft Collars and Rigid Couplings
Custom large bore shaft collars and couplings for drive train applications in wind power generation systems are available from Stafford Manufacturing Corp. The company’s shaft collars and rigid couplings are custom engineered for applications up to 16” and 8” I.D., and come in one- and two-piece configurations that can be modified to meet a variety […]
Six factors to remember about couplings in a motion system
Updated May 2019 || Physical values such as torque, torsional rigidity, spring stiffness, moment of inertia, imbalance, and zero-backlash play a major role in coupling design. Here are a few facts to keep in mind when you design your motion system. 1. Torque (Nm) is the product of an acting force and the effective length […]
