一、润滑油品的更新换代目前冶金企业里所使用的齿轮正向着高速度重载方向发展,原有的齿轮装置使用能力在不断地加大。如一初轧厂目前的生产能力已由解放初期的年产量50万吨,提高到200多万吨,由于作业率高了,轧制毛坯断面也加大了,24时连轧机组的人字齿轮座和伞齿轮箱齿面负荷已提高到10000公斤/厘米~2以上;二初轧厂已由设计能力年产210万吨提高到420万吨;半连轧厂的设计能力由原年产80万吨提高到
First, the replacement of oil products Metallurgical enterprises are currently using the gear is moving in the direction of high-speed heavy load, the original use of gear capacity continues to increase. As a first rolling mill’s current production capacity has been 500,000 tons from the early liberation of the annual output to more than 200 million tons, due to high operating rates, rolled rough section has also increased, at 24:00 even rolling mill herringbone gear The load on the tooth surface of the bevel gear box and the bevel gear box has been increased to over 10000kg / cm ~ 2; the second early rolling mill has been increased from its designed capacity of 2.1 million tons to 4.2 million tons; the design capability of the semi- Ten thousand tons increased to
