ELASTIC COUPLING

The primary purpose of an elastic couplings is to transmit torque from a driving shaft to a driven shaft and to accommodate shaft misalignment during operation. Elastic couplings also dampen vibration, torque fluctuations and torsional shock loads, even in arduous applications. Through careful and accurate product selection, correct installation and appropriate care of elastic couplings, substantial savings can be made in reduced maintenance costs and minimal downtime. These procedures also increase the L10 lifetime of the product. Timken Quick-Flex elastic 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 a simple, yet effective, drive mechanism. The only spare part required is a standby element that can be quickly changed when necessary. Inserts, which are resistant to chemicals, are manufactured from different grades of urethane to suit various industries. The red insert is suitable for most high-speed applications with high levels of vibration, the stiffer blue insert is designed for higher torque applications and the black insert can withstand extremely high torque requirements, replacing grid and gear couplings. An advantage of these elastic couplings over conventional units is direct replacement with virtually all comparable sized couplings. Quick-Flex elastic couplings require no lubrication and are also easy to install and maintain. Due to the high torque capacity of this range, the selected Quick-Flex solution is often smaller than the replaced coupling. This leads to a major weight saving on the drive and reduces stress on other components. These couplings accommodate angular misalignment up to 2º and parallel shaft displacement up to 7.92 mm
