Turbomachinery Package Specification Taurus 60 Compressor Set and Mechanical Drive
The gearbox is mounted on the driven skid and, together with the input shaft coupling, is
lubricated and cooled by forced-fed lubricating oil from the turbine. Gearbox journal and
thrust bearing temperatures are monitored by two simplex resistance temperature
devices (RTDs) at each radial bearing and two per thrust face on the thrust bearing. The
monitoring system is connected to one each of the radial bearing RTDs and one each
RTD from each side of the thrust bearing, with the remaining circuits available as spares.
6.1.2 Inter-body Speed-Increasing Gearbox
The inter-body speed-increasing gearbox will have a specific gear ratio and speed range
for the tandem compressor set application. The gearbox increases the output speed of
the driving compressor to the required operating speed of the driven compressor. The
gearbox output shaft direction of rotation is counterclockwise, when viewed from the aft
(exhaust) end of the package looking forward towards the air inlet end of the package.
The gearbox is mounted on the driven compressor skid and together with the input shaft
coupling, is lubricated and cooled by forced-fed lubricating oil from the turbine. Gearbox
journal and thrust bearing temperatures are monitored by two simplex RTDs at each
radial bearing and two per thrust face on the thrust bearing. The monitoring system is
connected to one each of the radial bearing RTDs and one each RTD from each side of
the thrust bearing, with the remaining circuits available as spares.
6.1.3 Primary Speed-Reducing Gearbox
The primary speed reducing gear will have a specific gear ratio and speed range. The
speed-reducing gearbox reduces the output speed of the turbine to the required
operating speed of the driven equipment, optimizing the power turbine speed for each
application. The gearbox output shaft direction of rotation is counterclockwise, when
viewed from the aft (exhaust) end of the package looking forward.
The gearbox is mounted on the driven equipment skid and, together with the input shaft
coupling, is lubricated and cooled by forced-fed lubricating oil from the turbine. Gearbox
journal and thrust bearing temperatures are monitored by two simplex RTDs at each
radial bearing and two per thrust face on the thrust bearing. The monitoring system is
connected to one each of the radial bearing RTDs and one each RTD from each side of
the thrust bearing, with the remaining circuits available as spares.
