BHS Getriebe GmbH will be showcasing its rotor turning gear capabilities in its booth at Power Gen Europe.
Units are used to prevent turbine rotors from warping as they cool to break away drive trains during plant start-up and to align shafts for maintenance and inspection. Breakout torques of 300-100,000 Nm and speeds of 0.2-400 1/min. are available.
According to the company's press release, BHS offer two designs of rotor turning gear. The simplest arrange is to attach the rotor turning gear to a free shaft end. If this is not possible, the rotor turning gear may be integrated in to the drive train by mounting it on a coupling guard or turbine pedestal and engaging with a flanged gear.
BHS Getriebe says more than 1,000 of these units are operation worldwide, many in large power plants.
