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 […]
Altra couplings for Navies around the world
Modern navies are comprised of a wide variety of sophisticated vessels, including aircraft carriers, destroyers, frigates, patrol boats and submarines. With more than 105 navies in the world, advanced battleforce and support ships continue to be commissioned at a steady pace to meet multi-mission duties, including war fighting and maritime security. Recent developments in technology, […]
R+W’s LPZ short spacer added to disc coupling line
In its effort to fill in and complete its flexible disc coupling offering, R+W has added a standard coupling adapter which provides customers with more configuration and connection options when selecting couplings for industrial applications. The LPZ spacer accompanies a quickly expanding product line and offers lateral misalignment capabilities in a very small package. It […]
New ARPEX all-steel coupling from Siemens
Siemens will present an additional series in the range of torsionally rigid all-steel disc couplings: the new N-ARPEX coupling with improved performance characteristics. An optimized disc pack and a revised component design facilitate the transmission of higher torques and speeds as well as a higher bore capacity with standard hubs. All-steel couplings can be used […]
GCH couplings with locking hubs
A leading packager of reciprocating compressor equipment required a reliable coupling solution for its line of compressor packages used at natural gas vehicle (NGV) refueling stations. These stations are needed to support the growing number of natural gas powered municipal bus and truck fleets as well as passenger vehicles. The multi-stage, skid-mounted compressors feed the […]
Coupling application profile: power plant induced draft fans
A major global industrial fan OEM needed a replacement coupling solution for an induced draft fan drive at a large power plant. The fan maintains system pressure slightly below atmospheric pressure on a coal-fired boiler at the facility. The existing fan drive used an old gear coupling design which had reached the end of its […]
Turboflex HS couplings for biomass-fired steam turbines
A leading global provider of power generation technologies required coupling solutions for use on three steam turbines at a series of new biomass power plants located in the UK. The three geared reaction steam turbines include a 23 MW unit and a 45 MW unit that will be fired by waste wood, while a 50 […]
Dual purpose of miniature couplings：motion control and power transmission
How to select couplings A simple and generally used method to select the most suitable coupling is the four step approach. That is, 1. Select the coupling type suitable to the intended usage 2. Select the material of the coupling in line with the environment of usage 3. Select the coupling size fitted to the […]
High-gain rubber couplings from NBK
NBK America now offers the XG Series of couplings. Why? TO keep pace with the evolution of servomotors. Couplings today are a key component for helping servomotor-driven setups deliver speed-response frequencies … without the problem of vibration that usually accompanies such designs. In fact, it’s difficult to get maximum servomotor performance with high-rigidity couplings such as […]
ROBA-DS shaft couplings tested by DNV GL
The compact ROBA-DS disk pack couplings by mayr power transmission have been certified by DNV GL. They ensure maximum safety for users on the high seas. Whether in the drives of ship propellers, mobile platforms such as drilling platforms for oil and gas extraction, or also in tidal power plants – the areas of application […]
