| The oil lubrication system is designed with ease of inspection and maintenance as one of its primary goals. Therefore, all of the oil connections are positioned in the lower half of the gear case for quick and simple access to the bearings, gears, and pinions. The oil reservoir is located with the package's baseplate. The reservoir interior is conveniently accessible through an oversized cover. Each reservoir has fill and drain connections and an easy-to-view oil level gauge. The oil cooler is sized to provide cooling under design and off-design conditions. The full-flow oil filter eliminates contaminants 10 microns or larger, and its mounting lcoation was selected for easy access to allow changing the filter without draining the reservoir. The auxiliary oil pump, with electric motor drive, operates automatically during start-up, shutdown and in emergency situations to provide additional overall package protection. The positive-displacement main oil pump is directly driven by the bull gear or driver shaft. The pump is oversized and will continue to provide lubrication to the system during coast-down to a safe stop. The system includes temperature and pressure control valves. Sensors continuously monitor inlet oil pressure and temperature, and provide machinery protection. Alarm or trip functions activate in the unlikely event they are required. The gearbox and reservoir operate at slightly above atmospheric pressure. Venting of the oil mist is done through a mist eliminator, which returns all of the coalesced oil to the reservoir. |
