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 connected to an intermediate shaft. A torsionally stiff misalignment coupling at the intermediate shaft’s rear end creates the second bending flexible pivot, which offers a double cardanic design. This unique combination of the intermediate shaft and the Rato DS is known as the VULKAN Integrated Shaft ...
Low weight, low inertia torque limiter
By Tobias Wolf, Product Engineer, R+W GmbH and Andrew Lechner, Product Manager, R+W America. The concept of weight reduction through the use of high tech materials is not a new one. But for those involved in the design of motion control and automation systems, the elimination of excess mass and inertia is often the difference between success and failure. Energy savings, higher throughput rates, and reduced downtime, all without compromise to quality or accuracy, are on the minds of almost every machine design engineer today. To address this requirement R+W has introduced a revolutionary new torque limiter, SL Series, with half ...
Misumi Now Offers Comprehensive Line Of Couplings
MISUMI Coupling types include high precision Single Disc and Double Disc Clamping models, many of which may be used with servomotors. Also offered are Oldham, Slit and N Couplings, as well as Jaw, Sleeved, Bellows, and Resin types, in a variety of sizes and configurations. The SCXW is a Double Disc type precision disc clamping coupling with high torque but no backlash. Its torsional rigidity is up to 26% higher than conventional (standard) disc clamping couplings. It suits applications requiring fast positioning precision. All the bolts are trivalent chromate plated and suitable for use in clean environments. The MFJGWK is available as ...
Zero Backlash Coupling Ideal for Belt Driven Linear Actuators
Due to greater demands in modern machine design and construction, R+W has developed its EK7 series of SERVOMAX Zero Backlash Elastomer Couplings. This coupling was specifically designed to mount to hollow bores with an expanding tapered clamping element, making it ideal for belt driven linear actuators. The EK7 provides design engineers with a number of advantages, including: · Most belt driven linear actuators require a shaft adapter in order to couple the pulley to a motor or gear head. The EK7 eliminates the need for this additional hardware. · In designs where motor shafts ...
Torque Limiters that Keep Overload in Check for Heavy Equipment
A different approach is needed when designing mechanical torque limiters for high horsepower drives. The basic principles of mechanical torque limiter design are similar to those that have been known since some of the first machines were built, yet it remains a dynamic field. Function, space restrictions, safety considerations and continuously changing machinery design drive the need for these components to evolve. [caption id="" align="aligncenter" width="500" caption="Typically, safety element torque limiters are supplied as a pre-set and self-contained package for integration into timing sprockets, sheaves and cardan shafts, like the one shown here."][/caption] In particular, high horsepower ...
