We spoke with Bobby Watkins of Ruland manufacturing to get an overview of some basic coupling installation best practices. Ultimately, even if a coupling is properly selected, poor installation can cause failures. “Always be sure your selected coupling is used within its ratings. We estimate here at Ruland that less than 25% of the couplings […]
What are the differences between claw and disc couplings
In addition to gear couplings, claw and disc couplings can be used to connect the drive motor and gearbox in crane and hoist applications. Like the gear coupling, these other two options are designed to compensate for angular, radial and axial shaft misalignment: • Claw coupling—Torsionally flexible, these couplings transmit torque via elastic buffers made […]
Twin Disc unveils heritage gallery for 100th anniversary
Twin Disc, Inc., a global player in power transmission technology for marine and land-based applications, unveiled the Twin Disc Heritage Gallery on Aug. 2, at the company’s Racine headquarters, in celebration of its 100th anniversary. The gallery, which takes up roughly 4,000 square feet of the first floor of the Twin Disc corporate headquarters, provides […]
New flex element/blade triangular bushing design
Ameridrives and Bibby Turboflex, two leading Altra brands, have developed the Tri-Bushing™, a unique flex element/blade triangular bushing design that increases the axial capability of high-performance flexible disc couplings used in turbomachinery applications. Flexible couplings for critical equipment must accommodate angular and axial movement due to thermal growth. In steam and gas turbine applications, machinery […]
Periflex VN couplings for water pumping system application
A robust coupling solution was needed for a large diesel-powered, artificial lift water pumping system used to push water up and over the Andes mountain range in South America. The complex system used a series of diesel engine powered pump stations installed on the side of a mountain to push water 4,000 vertical feet. The […]
Rexnord announces the 3000 Series MCF couplings
Rexnord is proud to announce the latest addition to our premium line of power transmission components, the 3000 series MCF coupling. MCF Couplings are used as an alternative to hollow shaft mounting options for large drive applications to simplify the assembly and maintenance of gear drives. It connects the head shaft pulley of the conveyor […]
What are some different styles of disc couplings?
Disc couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on general coupling selection. The following is an excerpt from the disc coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Specifically, Watkins covers different styles of […]
Are disc and bellows couplings similar?
Disc couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on general coupling selection. The following is an excerpt from the disc coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. “Disc couplings. The disc coupling […]
VN coupling for crawler dozer
A major global construction equipment manufacturer needed a coupling solution for its largest bulldozer. The massive 24-ton, 214 HP machine features a 135-in. wide blade and can be used for heavy dozing as well as fine grading. The coupling connects the main diesel engine to the hydraulic pump that powers the propulsion tracks and all […]
Machines use Zero-Max CD couplings for component balancing
Now some balancing machines incorporate pre-balanced CD Couplings from Zero-Max to get reliable system performance. Prebalancing aids on-machine trim balancing during assembly into the balance machine. CD Couplings have a combination of operating characteristics that support reliable automotive-component balancing. Making this possible is the coupling’s proprietary Composite Disc pack which in this application is designed […]
