High Speed Power Shifting Transmission for Gas Turbines 670727

A 300 hp, four speed, forward and reverse, power shifting test box has been designed, fabricated, and tested by the Eaton Yale & Towne Research Center at a rated input speed of 30,000 rpm. The concept incorporates a torque limiting clutch on the input shaft to limit inertia shock loads during shifting, and unique expanding sleeve clutches for changing gear ratios. Expanding clutch material and design were developed through extensive bench testing and computer investigation. A 30,000 rpm high pressure, controlled leakage rotating seal was developed for the input shaft. Limited experience with the vehicle installation is also discussed.
