2020-7-29The existing gear coupling design was typical of the technology available when the plant was built in the early 1970s. Where gear couplings did not limit axial movement of the motor shaft, sleeve bearings were used. This old technology configuration increased wear and shortened life spans of both the motor sleeve bearings and the gear couplings
Recent failures of pulveriing wheels in fan mills of a steam turbine power plant show that the dovetail-groove area of the main components the front disk and the back disk is vulnerable.
