摘要： An integral turning gear is machined onto one-half of a turbine rotor shaft coupling or on a pedestal of a rotor shaft for engagement with a motorized pinion for rotating the shaft of the turbine, for example during shutdown. The gear teeth are integrally formed on the coupling or shaft and do not require additional length of axial rotor span or introduce significant stresses. The motorized pinion may engage the integral turning gear teeth to rotate the rotor, for example, during turbine shutdown to prevent the rotor from sagging while cooling from elevated temperatures.
