GKN plc (“GKN”) has announced that it has agreed the sale of its Stromag business (part of the GKN Land Systems division) to Altra Industrial Motion Corp. for a cash consideration of €184 million (£164 million) and the transfer of debt-like obligations of approximately €14 million (£13 million) for a total enterprise value of €198 […]
R+W adds the SP3 Bellows Coupling to its high speed coupling line up
Bellows couplings are well known in highly dynamic precision applications because of their continuous symmetry, high torsional rigidity, and low moment of inertia. Many of the same characteristics are also very well-suited to high speed operation. Standard design balance for bellows couplings is typically up to 10,000 rpm, with the limiting factor being only the […]
The 4 best torque limiter videos on the web
Torque limiters are essential for preventing motion system damage in the event of a jam or overload situation. With personnel safety a paramount as well, it’s important to understand how torque limiters function within a given application. In this list, we’ll cover a few of the most viewed and most informative torque limiter videos on […]
Case Studies: Helical flexure for two different applications
Application story 1: Challenge: A Helical customer had planned to use the AE087 or AE100 to connect a potentiometer to a control lever. The operating atmosphere included both salt and dirt, plus high parallel misalignment potential. They wanted to use a “D” bore to fasten the lever to a shaft, then connect the coupling to […]
Shaft couplings for torque transducers
Design ROBA-DS disk pack couplings of the type series 9110 and 9210 from Mayr are especially adapted for the attachment of HBM torque transducers. Different types of construction and flexible combination possibilities permit the integration of measurement flanges in almost every test stand and drive constellation. Function ROBA-DS disk pack couplings compensate for axial, radial […]
Block shaft coupling advantages and disadvantages
Advantages: Protects shaft-support bearings by exerting consistently low reactive forces, even under large misalignments Homokinetic transmission – driving and driven shafts rotate at exactly the same speed at all times Zero backlash and high torsional stiffness Electrical insulation Accommodates moderate radial misalignment in a short length Accommodates relatively large axial misalignment Easy installation in blind […]
Micro-adjustable shaft collars eliminate guesswork from fine positioning
Stafford Manufacturing Corp. is introducing a new line of micro-positioning shaft collars for linear motion and other applications requiring precise and fully repeatable positioning. Stafford Micro-Positioning Shaft Collars are fully sealed to protect their internal threads from contamination and provide 0.200-in. total adjustment in 0.0005-in. increments. Ideally suited for use as end stops in linear […]
High speed shaft couplings | Ameridrives couplings
Ameridrives provides custom-designed, light weight couplings that are capable of transmitting high torques at high speeds while accepting significant levels of angular, radial and axial misalignment. Units require no lubrication and can be supplied with composite materials for electrical insulation. Product Features: Quality materials and manufacturing processes ensure high reliability Reduced shaft stress Designed for […]
Old component new tricks: The future for mature technologies
There is no shortage of new engineering concepts. But there are components (including couplings) for which it has been years if not decades since major design advances. By now, many of these motion system staples are standbys … and improvements are more incremental in nature. Plus, customization bridges the gap for any application-specific nuances in […]
Couplings tips for specific installation requirements
Coupling variations complement specific machine dynamics and meet specific application criteria. Rigid coupling designs handle drive components already in alignment and flexible couplings compensate for post-installation misalignments. Misalignment potential, temperature, mechanical resonance and other factors make some couplings better suited for given applications. Here are some different coupling types and their most common applications. Rigid […]
