BMG’s Timken Quick-Flex couplings are designed to transmit torque from a driving shaft to a driven shaft and to accommodate shaft misalignment within the drive. These maintenance-free couplings also dampen vibration and torque fluctuations and smooth torsional shock loads.
“An advantage of the couplings over conventional units is direct replacement with virtually all comparable sized couplings,” states Carlo Beukes, general manager power transmission at BMG. “Quick-Flex couplings also require no lubrication and are easy to install and maintain. Due to the high torque capacity of this range, the selected QF solution is often smaller than the replaced coupling. This leads to weight saving on the drive and also reduces stress on other components. These couplings are ideal for heavy start ups of shock loads because they have an impact capacity in excess of 200% of the maximum torque rating.”
Simple construction
Timken Quick-Flex couplings consist of two steel coupling hubs which are attached to the drive and driven shaft. A urethane element wraps around the two hubs and provides an effective drive mechanism. The only spare part required is a standby element that can be quickly changed when necessary. The cover, which secures the insert in place, can be installed on either side of a standard coupling hub and will not move under misalignment.
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. Unlike a standard jaw-type or gear coupling, there is no metal to metal contact between the hubs. This prevents any possible damage to the ironware during an element failure. The urethane insert can be easily changed without moving the hubs or shafts and no re-alignment of components is necessary.
The couplings are compatible with shaft sizes from 10 to 285 mm and can accommodate a wide speed range – from below 100 to 12 000 rpm – and torque ratings range from 43 to 188 795 Nm depending on the selected element and cover design.
The flexibility of this design makes these couplings suitable for many applications – from high-speed low torque excessive vibration drives, to a low speed high torque application. These couplings accept angular misalignment up to 2° and parallel shaft displacement up to 1 mm.
