Rocom Couplings Corp. has recently announced the addition of Brian Barnhart to its leadership team. Brian brings 20 years of experience in power transmission and motion control industries, including six years at a leading flexible coupling manufacturer. Brian’s ability to synthesize his experience in product design, applications, and field service engineering aligns with Rocom’s commitment […]
RoCom Coupling Corp’s D Series heavy duty coupling
A heavy-duty coupling. Has a large amount of misalignment and axial motion. More space between each beam for greater misalignment All couplings have an inside relief so the shafts will not touch the beams at the maximum misalignment. Clamps are an integral part of the coupling and use hex socket cap screw with a black […]
New from Ruland: slit couplings
Ruland Manufacturing and Reliance Precision have agreed to cooperate by offering Reliance designed and manufactured slit couplings through Ruland’s eCommerce platform and extensive worldwide distribution network. Ruland will stock and bore to size a wide selection of slit couplings in its Marlborough, MA location. The addition of slit couplings gives Ruland a more complete zero-backlash […]
New coupling technologies offer more support for encoder requirements and washdown settings
The location of mechanical couplings — connecting rotating shafts powered by electric motors and fairly close to the loads being moved or manipulated — makes it an ideal place to optimize the performance of machine axes. No wonder that our 2020 Design World Trends survey of industry experts indicates an uptick in innovation related to […]
Twin Spring Coupling’s flexible coupling technology for replacing U-joints and more
Industrial machinery runs 24/7 365, modern life demands a lot from this machinery and when the equipment is not running it costs money through lost orders, worker down time, and customer dissatisfaction. High speed couplings — couplings, beam and elastomeric, can only run at 4° misalignment before they cause equipment failure through increased vibration and […]
New leadership and ownership at RoCom Couplings Corp.
California-based RoCom Couplings Corp. — which specializes in triple-start beam couplings — is now under the ownership and management of Randy Kingsbury and Daniel Miano. This follows more than more than 38 years of ownership by the Jewell family. The manufacturer of high-performance flexible shaft couplings has also relocated operations from Huntington Beach to Santa […]
Do I need to worry about windup during my coupling selection?
Often confused with backlash, windup is easy to overlook when selecting couplings for a motion system. But windup is an important consideration that can cause real problems if not factored-in early in the design process. Bobby Watkins of Ruland Manufacturing gives us a few reminders for thinking about windup in during your selection process. “Windup […]
What are the pros and cons of beam couplings?
Beam couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on proper coupling selection. The following is an excerpt from the beam coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. “We’re going to start off […]
Flexible-coupling considerations for motion-control designs in OEM and plant setups
Couplings connect rotating shafts in equipment powered by electric motors and other drives. All transmit torque and angular velocity. Flexible variations compensate for misalignment. Many of the latter even address vibration and improve system dynamics. Design considerations include machine or installation construction and backlash, torsional stiffness, damping, inertia, torque ratings, maximum rpm, size, misalignments, ease […]
Reaction forces from couplings: How to prevent or mitigate?
All flexible couplings compensating for misalignment cause reaction forces, and their effect is significant if misalignment is excessive. These often-overlooked reaction forces transmit to connected shafts and support bearings, and can cause damage to motion axes — especially on precision designs with delicate bearings and slender shafts. Though couplings get their compliance from elastomeric deflection, […]
