Our team hereby welcomes you to Boston in June for the 2019 Robotics Summit — June 5 and 6, 2019 to be exact. Focused on the design, development, manufacture, and delivery of commercial robotics, the Robotics Summit is actually co-located with the DeviceTalks event at the Seaport World Trade Center. As an attendee, expect to […]
Are you overlooking duty cycle in your coupling selection?
Duty cycle is a critical but often overlooked consideration during the coupling selection process. Critical elements like types of motion, potential shock load scenarios, and start/stop situations should all be evaluated when selecting a coupling for your next motion system application. Here, Bobby Watkins of Ruland Manufacturing gives us some insight on what to look […]
Step-Flex couplings from Miki Pulley improve ball screw performance
Miki Pulley’s Step-Flex Couplings improve ball screw performance while solving resonance and vibration problems. The Step-Flex is an altogether new class of shaft coupling. The Step-Flex coupling design has a two-part elastomer element combination. This assembly dampens vibration caused by the actuator carrier when struggling to find its home position by making small adjustments in […]
Dodge paraflex elements
Dodge Para-Flex elements are manufactured with reinforcing fabric tension cords that transmit much of the torque during operation and offer a wear indicator to the user when the element should be changed out. The uniform and centered beads, in the foot of the tire element prevent it from pulling out during operation. Additionally, the tire […]
Servo couplings: Stiffness, damping, hunting, and stabilization considerations
Here we address considerations when specifying servo couplings to satisfy servo requirements — ever-evolving specifications that become more demanding all the time. By Tetsuya Niwa • Director of product planning and development Kei Yamada • Product Manager — Product planning and development Hiroki Goto • engineering specialist Paulo Castelo • Technical solutions supervisor • NBK America […]
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 […]
Damping servomotor couplings — New ways to use flexible couplings to minimize hunting and boost system stability
August 27, 2017 update: The full-length technical feature on this servo-coupling topic of damping and gain setting is now live. New technological improvements in servomotors have spurred dramatic improvements in response frequencies. The catch is that vibration (and hunting) tend to arise when designers apply high gain settings to servo systems and use advanced couplings […]
ContiTech: Elastic coupling elements
Overview Elastic coupling elements are used as spring elements in diesel drives for vibration-free power transmission. They are used in vehicles, ships, power stations and drives in the field of mechanical engineering. Benefits & Features The primary function of elastic coupling elements is to insulate torsional vibrations. Elastic coupling elements have an extremely broad torsion […]
The upside to downsizing elastomeric couplings
Located in the greater Houston area, GPM Pump and Seal is a provider of pumps, pump parts, mechanical seals and complete pump systems for oil and gas, petro-chemical, mining, water, wastewater treatment and other applications. They also specialize in pump and mechanical seal repair for all major OEMs. Elastomeric couplings are the industry standard for […]
Timken Quick-Flex couplings
Timken Quick-Flex elastomeric couplings are durable enough to face the challenges of harsh environments, yet need minimal maintenance. They are easy to install and require no lubrication. Timken Quick-Flex couplings operate without any metal-to-metal contact. Because the metal hubs don’t wear, the elastomeric insert is the only spare part users will need. For especially harsh […]
