Couplings Cure Gensets’ Destructive Vibration
Rubber-in-compression couplings help protect gas- and diesel-driven generator sets from torsional vibration and the possible catastrophic effects of resonance occurring if this were to coincide with the natural frequency of the system, says couplings manufacturer Renold Hi-Tec. The company explains torsional vibration is an inherent feature of any internal combustion engine as pulses, or peaks in torque, occur as the pistons are driven on their power strokes when the fuel and air mixture ignites.
New Propulsion Couplings to Launch at Workboat
Renold Hi-Tec Couplings, of Halifax, U.K., will debut a new range of high temperature, marine propulsion rubber-in-compression couplings on booth 3809 at the International Workboat Show in New Orleans from December 3-5, 2014. The new HTB-MP range is a second generation of couplings based on the existing HTB-GS range. According to the manufacturer, the intrinsically fail-safe nature of rubber-in-compression couplings ensures continuous operation and avoids the loss of drive that could be experienced with other coupling types as a result of failure.
