ÆrØ is an island off the coast of Southern Denmark. Since the 70s and 80s, the island has been a pioneer community for renewable energy projects. The mayors have obligated themselves to make ÆrØ CO2-neutral before the year 2025. Windpower plants, district heating based on solar thermal energy, and photovoltaic power cover most of the […]

Precision sleeve couplings now include hex, square, and threaded bores
A full line of precision sleeve couplings that now includes new bore styles to accommodate hex, square, threaded, and different size shafts has been introduced by Stafford Manufacturing Corp. Stafford Precision Sleeve Couplings feature a solid center section with the Accu-Clamp design which incorporates integral self-centering clamping collars at both ends for mating two shafts with […]
The eight best ways to wreck your coupling driven system
Keeping a servo-driven system running at peak efficiency is no simple feat. Misunderstanding performance criteria such as misalignment, torque, or RPM can be all it takes to cause a critical failure. The following are the eight best ways to consistently sabotage or damage your coupling driven system (and how to avoid them in the future). […]
Zero-Max offset couplings with large range of parallel misalignment capacity
Zero-Max Schmidt Offset Couplings provide machine designers with a proven method to ensure machines operate with constant phase accuracy and constant speed throughout the rotation and cycle of the machine. Where precise performance of system components is required and reduced machine size is important, these Offset Couplings provide a solution. They are available in sizes […]
Safe dimensioning of locking assemblies for extreme loads in applications with belt conveyor pulleys
Ignoring induced forces or the faulty design of belt conveyor pulleys can cause high repair costs. Resulting damage may show itself in shaft breakage, axial movement or plastic deformation of the pulley bottom. Apart from that, downtime losses accrue which can quickly amount to several millions. For instance, the capacity of a large ship loader […]
What are frictional locking assemblies?
If you want a wear-free way to join shaft components, look no further than locking assemblies. These frictional devices take the place of keyed connections that wear and slip over time. Let’s take a closer look at how locking assemblies work — including their advantages over traditional keyways in high-torque applications. What is a frictional […]
Ringfeder locking assembly in a ball mill for cement production
Edited by Mike Santora The Challenge After maintenance engineers had examined the ball mill unit thoroughly, the cause of the problem seemed to be the shaft-pinion connection, or to be more exact, the locking assembly that connected the solid shaft with the pinion. Measurements showed the assembly to be out of tolerance by a whopping […]
Voith adds IIoT functionality to torque limiting couplings with Dtect
Voith now offers Dtect — an intelligent monitoring system that provides real-time data of driveline performance and coupling status. With Dtect operators can take actions to prevent potential problems and avoid unplanned downtime. By supporting better decision making, Dtect also increases productivity and significantly lowers production and maintenance costs. Dtect enables comprehensive monitoring of a […]
June Robotic Summit: Register now and we’ll see you in Boston
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 […]
What are gear couplings and how do they work?
Gear couplings are designed to transmit torque between two shafts that are not collinear. They typically consist of two flexible joints—one fixed to each shaft—which are connected by a spindle, or third shaft. The gear coupling connects the drive motor to the gearbox in hoist mechanisms, but it can also connect the gearbox directly to […]
