When selecting couplings for precise motion applications there are often questions about the most suitable approach for optimizing both performance and economy.
April 6, 2023
Precision flexible shaft couplings come in two basic forms, both of which are designed to operate without backlash or excessive inertia while compensating for inevitable misalignment offsets between motor/gearbox and load. Torsionally stiff couplings are made with metallic flexible elements and with the intent to eliminate as much twisting deflection as possible so that the rotation of both shafts is kept as well synchronized as can be.
ABB is celebrating the “floor pour” of its newest U.S. flagship campus at 18250 W. Lincoln Avenue. The greenfield location in New Berlin will serve as the U.S. headquarters, manufacturing facility and distribution center for the Drives and Motion Services businesses. The new facility is anticipated to open in late 2024 and will accommodate 720 ABB employees. Approximately $100 million is being invested in the project and is expected to create 100 new jobs over the next three years.
This study presents a simulation method for considering complex wheel bodies in an analytical tooth contact model. The wheel body is considered using reduced FE stiffness. Reduction points are defined over the width and linked with the analytical gear.
For cylindrical wheel bodies, comparative calculations show fewer deviations from the expected results with the new method. This is due to the additional degrees of freedom in the FEM model. In the calculation with cylindrical wheel bodies, bending due to axial force in tooth contact could also be verified in addition to the deformation in tooth contact and the influence of the shaft-bearing system.
PTE will feature a variety of new component technologies online for bearings, motors, couplings, brakes, gear drives, and motion control systems leading up to Hannover Messe 2023 in Germany. Here is a preview of some couplings suppliers to check out if you're planning on attending the event online or in-person in April.
I think I spend more time talking about ball bearings today than at any other time in my career. Ball bearings have always had a large place in automotive, but not typically in high demand positions—other than a few niche areas. High demand positions, such as axles and planetaries, were typically reserved for tapers, needles and cylindricals. The landscape is changing quickly.
A high force Linear DC servomotor from Moticont has been added to their expanding line of voice coil or moving coil motors. The LVCM-095-038-01 Linear Voice Coil Motor is a true servo motor featuring zero cogging, high accuracy, and high repeatability when operated in a closed positioning loop
In an age of online shopping and mass production, distribution centers are on the rise. Naturally, the amount of packaging is also increasing, and a practical solution is needed to close the loop on recycling so much waste. One major tool distribution company in the U.S. Midwest has found its own “circular economy” answer to this problem by using EcoShield Heat Sealable Paper to recycle used boxes into dunnage bags.
Regal Rexnord Corporation will feature its mobile, scalable, approachable and energy-efficient end-of-the-line sortation system, ModSort, at LogiMat 2023, Booth 1A41 in Hall 1. The show takes place at the Stuttgart Trade Fair Center (Stuttgart, Germany) from April 25-27.
Nidec Leroy-Somer has signed an agreement with Airbus to develop an electric motor for its hydrogen-powered fuel cell engine prototype, as part of Airbus’ ambition to bring the first zero-emission commercial aircraft to market by 2035. The long-standing expertise and extensive know-how of the French electric motor manufacturer, who already provides proven advanced technologies to many demanding industries, such as Navy, Nuclear, Railway, Automotive and Robotics is now collaborating on Aviation decarbonization.
