A locking device is a mechanical component that prevents mated shafts and other machine elements from moving out of position when subjected to external forces. Operating conditions such as initial installation error, temperature variations, vibration and others can all cause issues. These are critical components. The safety of an entire system often relies on locking devices. […]

PTDA’s industry research reports accelerating growth in 1Q2017
The first quarter 2017 Sales History & Outlook Report (SHOR) released by the Power Transmission Distributors Association showed power transmission/motion control (PT/MC) distributor sales began to rise. The most recent 12 months of sales remain 1.9% below the year-ago level, but several positive indicators suggest total sales will be above the year-ago level in the […]
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 […]
End-to-end coupling solutions for cranes and hoists
When it comes to gearbox coupling applications, some misalignment is unavoidable. This is especially true for cranes and hoists due to their very heavy loads. Fortunately, you can manage misalignment by choosing the right couplings. Here are some options specifically for cranes and hoists: Connecting the Gearbox and Cable Drum Recommended for crane-lifting mechanisms, barrel […]
Lateral mounting safety couplings for extruders
R+W has expanded its line of ST series safety couplings, with a specially designed version now available for the protection of extruding equipment. Taking advantage of the ball-detent safety element system, the driving and driven ends separate within milliseconds of a torque overload, protecting the extruder from damage and reducing expensive repairs and costly downtimes. […]
TB Wood’s cost savings calculator
TB Wood’s has created a new program that allows users to quantify cost and savings when selecting a Sure-Flex Plus EPDM or Neoprene sleeve. The program is now available at www.tbwoods.com, or it can be installed as a smartphone app on any Android or Apple device. Users simply input their current maintenance interval, cost of downtime, […]
Sulzer finds engineering talent with summer intern program
Investment is an important process for any business. Investment in new facilities and manufacturing tools keeps the company modern, while investment in R&D helps to keep it at the top of its game within the industry. Of course there is another type of investment that shouldn’t be overlooked; investment in people. The Sulzer summer intern […]
Shaft collars, couplings, and mounts for conveyor systems
A full line of shaft collars, rigid couplings, and mounts for building conveyors with varying load capacities and environmental considerations are available from Stafford Manufacturing Corp. Stafford shaft collars, couplings and mounts are suited for use in virtually all conveyor systems as stops, spacers, and mounting devices for guides, rollers, sensors, and other structural and […]
Turboflex Plus couplings for turbomachinery applications
Ameridrives and Bibby Turboflex, two international flexible coupling manufacturers, have collaborated to introduce a new series of high performance disc couplings designed to meet the stringent requirements of today’s turbomachinery market. The new Turboflex Plus couplings combine Turboflex and Ameridisc disc coupling technologies together with the experience of the Ameriflex diaphragm coupling to create a […]
