Bearing Man Group's (BMG) QM flexible couplings are designed to transmit torque from a driving shaft to a driven shaft and accommodate shaft misalignment within the drive. They also dampen vibration, torque fluctuations and torsional shock loads.
"A Quick-Flex coupling consists of two steel coupling hubs, which are attached to the drive and driven shaft. A urethane insert wraps around the two hubs and provides a simple, yet effective, drive mechanism. The only spare part required is a standby wrap-around insert that can be quickly changed when necessary," says Carlo Beukes, product manager, power transmission, BMG. "Advantages of QM couplings over conventional units include direct replacement with virtually all comparable -sized couplings, they require no lubrication and are also easy to install and maintain."
Once the two coupling hubs, insert and cover have been installed and aligned for the first time, the coupling hubs do not need to be moved again for the life of the equipment. The simple, compact design means there is no possible interference between the coupling hubs if the insert fails. The urethane insert can be easily changed without moving the hubs or shafts and no re-alignment of components is necessary.
Important features are excellent balance allowing for high speed applications, low maintenance with no lubrication need and reduced downtime. Unlike a standard jaw coupling for example, there is no metal to metal contact. These couplings accept angular misalignment up to 2º and parallel shaft displacement up to 7,92 mm.
