Radial Drive Shaft

The radial drive shaft assembly is located in the 6 o’clock compressor front frame (CFF) strut of the LM6000 turbine. The shafts serve to transmit torque from the inlet gear box to the transfer gear box. The drive shaft assembly consists of three machined tubular steel shafts, housing and bearing.

The upper radial shaft is splined at the upper end to the inlet gear box and the lower end to the radial mid shaft. The shaft is enclosed by the front frame and supported by a ball bearing at its lower end. The radial mid-shaft is splined at the upper end to the upper shaft and at the lower end to the lower shaft. The mid-shaft is enclosed in a housing and supported by a ball bearing at its lower end. The lower radial shaft is splined at the upper end to the mid-shaft and at the lower end to the transfer gear box.
