武钢冷轧厂使用的五机架冷连轧机,最大轧制力2500t,最高线速为1800m/min,工作辊轴承采用的是四列圆锥轴承。过去,该机组工作辊轴承使用润滑脂润滑,一般寿命为600h,耗脂量每月为20t。改用西德REBS公司设计制造的油气润滑装置后,轴承寿命提高了3倍,个别轴承运行已达2000h以上,现在仍能继续工作。下面就油气润滑系统的调试与应用时应注意的一些问题进行探讨。
Cold rolling mill used in the five-stand tandem cold mill, the maximum rolling force of 2500t, the maximum line speed of 1800m / min, the work of roller bearings are four rows of tapered bearings. In the past, the unit work roll bearing grease lubrication, the general life expectancy of 600h, fat consumption of 20t per month. Switch to West Germany REBS design and manufacture of oil and gas lubrication device, the bearing life increased by 3 times, some bearings have been running more than 2000h, and can still continue to work. The following oil and gas lubrication system debugging and application should pay attention to some of the issues discussed.
