Unbreakable rubber-and-fabric isolators curtail energy waste
Vibration occurs in all rotating or reciprocating machinery as a result of forces generated within it. Sometimes the vibration is intended, as in vibrating screens and vibrating conveyor sections, used by the food, beverage and the mineral processing and bulk handling industries, for example. Sometimes it is caused by imbalances in rotors, bearings, springs, and gears as vibration migrates from its source to surrounding structures and wear-prone components. If this vibration is not controlled within its intended limits – and where metal springs may bottom out, settle, crack, or break occur as a result – the consequences of unintended actuation and isolation patterns can include: Energy waste due to kinetic energy required for unwanted vibration Bottoming out under overload and surge, sending a large amount of stress to all of the machine’s components. Bearing failures, metal spring cracking and collapse, metal structure cracking and weaknesses – potentially leading to unexpected plant shutdowns. Operator fatigue and noise nuisance (NVH – noise, harshness, and vibration, which is increasingly a factor in workers’ compensation issues) A simple, robust, and effective means of solving vibration and isolation problems created by such equipment is provided by Marsh Mellow springs, which are fabric-reinforced solid rubber isolators used for quiet isolation of machinery vibration and for general shock absorption throughout industry. The cylindrical springs, developed by Firestone – the world’s biggest producer of air springs for isolation and actuation – are used world-wide as an alternative to metal coil springs for applications involving building, construction, computer, electrical and electronic equipment isolation, including with motors, gearboxes, compressors, conveyors, materials handling machinery and shock absorbers. Marsh Mellows give consistent performance regardless of changing loads, while offering high lateral stability and compact size, says James Maslin, Technical Product Manager, for Marsh Mellows’ Australian distributor, Air Springs Supply Pty Ltd, […]
