This photo shows an inside look into an automatic turning gear. The SSS Clutch is employed to turn at runout the hot rotors in steam turbine sets, gas turbine sets, and compressor sets, and to break away the whole machine set. There are many possibilities of application such as in this example, the turning gear can be flanged onto the turbine gear, combined with gear motors, worm gears, bevel helical gears or cyclo gears, and connected to the pinion shaft. It can also be used when a shaft end is not accessible, for pumped air storage plants, and in a coaxial arrangement with an SSS Clutch. SSS produces and sells hundreds of these each year.
