(3) Working environment - 40 ~ 50 , the mouth is lower than 0 , before the start of lubricating oil should be preheated to 0above, the speed reducer can be used in positive and negative two directions. Characteristics: (1) The center distance, the main parameters such as the transmission ratio are optimized, the main zero and the parts are interchangeable. (2) The gears are made of high quality alloy steel, which is hardened by carburizing and hardening, and the hardness of the teeth is called hrc54-62. (3) Small size, light weight, high precision, high bearing capacity, high efficiency, long life, high reliability, stable transmission and low noise. (4) The oil pool is normally used for cooling, and when the heat power is not satisfied, the cooling coil can be cooled by circulating oil lubrication or fan.

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

Housing material is high density aluminium alloy ADC-12. Gear profile type ZK which efficiency up to 0.9. Other China made gear profile type is in ZA which efficiency up to 0.7 only. Hobbing tools for ZK profile are much expensive more than 10 times than ZA. Material of worm shaft is 40Cr (ASTM 5140). Others makers are using 45# steel which quality is poor while using it as worm shaft. Material of brass on worm wheel is ZQSnD10-1 (DIN GB-CuSn10/2.1051)(BS PB1) which other China makers are using ZQSND9-4 only. Bearings from FAG bearings China OEM makers. Synthetic lubrication oil of TAXAS brand. 100% running test before ex-factory.
