A leading global manufacturer of oil and gas drilling equipment needed a robust coupling solution for use on its 1,000 ton top drive. The 2,000 HP drive uses two AC motors, suspended from the rig’s mast, to rotate the drill string of pipe sections into the well hole. These pipe strings can reach lengths of […]

Gear grip couplings in mulch blower application
A leading manufacturer of mulch blowers and hydro seeders needed a coupling with a large misalignment capability for one of its bark and mulch blowers. The commercial blower is used to spread mulch for landscaping, erosion control and other applications. The shaft-to-shaft coupling is positioned between a diesel drive engine and a LOB style blower. […]
What are couplings for power-transmission drive shafts?
Updated May 2019 || As outlined in our coverage of couplings for motion control — here at this couplingtips.com article — couplings connect rotating shafts powered by a drive of some type — often an electric motor. All couplings serve to transmit drive torque and angular velocity. But applications for motion control (such as axes […]

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 […]
Gear couplings from Rexnord
Falk Lifelign Gear Couplings’ triple-crowned teeth are crowned on the root, tip and face to articulate freely and minimize wear caused by misalignment. By eliminating tip-loading while reducing backlash and radial clearances, Lifelign’s triple-crown teeth can help protect equipment from damaging loads. Features & Benefits: 13 models for general purpose, high-speed and high-torque applications Large […]
Coupling options for pump and compressor applications
When designing pumps and compressors, you’ll need to use couplings that balance efficient torque transfer against the ability to withstand vibration, shock loads and misalignment between the motor and drive shaft. Ringfeder offers four coupling options that help do just that. TNR Coupling consists of an aluminum housing and steel hub, separated by cylindrical elastomer […]
Gear coupling inner tubes from Misumi
Kohara Gear Industry coupling inner tubes from Misumi put the tooth surface high-frequency hardening as the outer cylinder of this easy attachable and detachable gear coupling. It is a durable product subjected to a chromate plating. Tooth type has applied crowning and it can be used up to a maximum of 5° even if there […]
Gear coupling for nuclear waste handling crane
A coupling solution was needed for a crane used at a European nuclear waste reprocessing plant. The nuclear waste is transported around the facility in large, self-contained and shielded packages (flasks). A special overhead crane is used to raise and lower the heavy flasks at various reprocessing stations throughout the plant. The crane is powered […]
Custom Ameriflex couplings for polymer resin pumps
A major global petrochemical company experienced a coupling failure on a polymer pump in one of its larger resin processing facilities. The coupling problem caused expensive, time-consuming production line shutdowns. Ameridrives was contacted to provide a solution. Gear couplings were initially installed on all the polymer pumps between the pumps and gearboxes for this high-torque, […]
