Gear Reducer: Double helical involute, double reduction. Its unique features result in a gear reducer that can withstand heavy cyclic loads and provide years of service with minimal maintenance. Meets or exceeds API 11 The torque rating of the gears shall be as determined by API Specification 11E and AGMA Specification 422.03. -All pinions and shafts shall be made of 4145 high alloy steel. Material certifications are required. Gear Reducer Housing:Gear Reducer is a two piece housing is ASTM A48 gray iron casting Gear Reducer Lubrication:An exclusive feature of every VENDOR unit is its gearbox Positive oil lubrication system. This unique system should uses oil buckets to fill troughs that continuously feed the right amount of oil to each gearbox bearing, regardless of the direction of rotation, at pumping speeds as low as 1 strokes per minute without modification (wipers not required). The reducers oil capacity should be large enough to operate with no sump. Meets API 11E NB:Gear reducers shall be shipped full of oil and ready to be placed into operation High/Intermediate/Low Speed Bearings:The gear reducer should contains properly sized anti-friction bearings, rather than energy-consuming bronze bushings. Each bearing is set in a carrier for ease of removal and installation. Should meets or exceeds API 11E Gear Reducer Seals:High and Low speed shaft should use Butadiene acrylonitrile rubber seals. Meets AP111E Section 7.4.9
