Turbomachinery Package Specification Taurus 70 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.
