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 […]
Disc pack couplings for explosion-protected atmospheres
Having experienced increased demand for torsionally rigid disc pack couplings for use in explosion-protected atmospheres, R+W Antriebselemente GmbH has expanded its range of industrial couplings. The disc pack couplings in the LP1, LP2 and LP3 series – including the 25,000 size – are now available for use in ATEX areas. The R+W disc pack couplings […]
Ringfeder talks couplings for aeroderivative gas turbines
By Ringfeder Power Transmission Gas turbines are available in many different designs and the power output of the individual models varies considerably – from 200 kW to more than 400 MW. The performance of gas turbines for industrial applications typically ranges from 5 to 40 MW. Dependent on the power, the speeds vary from 3,000 […]
Dodge Poly-Disc couplings
Poly-Disc Couplings This elastomeric “pin style” flexible coupling from Dodge has a molded polyurethane disc that helps cushion shock loads. It requires no lubrication and no periodic maintenance. Both flanges on the Poly-Disc coupling are machined all over and taper bored for Taper-Lock bushings. Specifications Sizes: 2.625 to 10 Bore Range: 0.5 to 3.25-in. [13mm […]
Dodge disc-style couplings
The Dodge Disc coupling offers torque capacity and misalignment capability resulting in longer life and improved reliability. Disc couplings have become the preferred design for pumping and compressor applications used in the oil and gas industry due to the high torque, speed, misalignment, and maintenance-free features. The advantages of the disc style coupling have also […]
Update on flexible-coupling considerations for OEM and plant designs
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 […]
