| 1)轧机负荷大，但辊径和轴承尺寸都受轧辊尺寸的限制，而不能无限制地加大，因此轧辊轴承所受单位压力大，超过一般用途轴承的2～5倍; 1) mill load is big, but roll diameter and bearing size is limited by the roll size, not unlimited increase, so the pressure roll bearing by unit, 2 ~ 5 times more than general purpose bearing; (2)高速是现代轧机发展趋势，因此轧辊轴承工作速度范围变化越来越大; (2) high speed is the development trend of modern rolling mill, so the speed range of roll bearings is increasing. (3)工作环境恶劣，受热不均，温度不稳定； (3) the work environment is bad, the temperature is not uniform, the temperature is unstable; (4)换辊频繁； (4) changing rolls frequently; (5)板材精度要求高。根据轧机的工作特点，因此对轧辊轴承提出了较高的要求:要求轴承承载能力高，旋转精度、极限转速高，要结构简单，易于装拆等。因此根据轧机工作要求和实际情况，轧机轧辊轴承的设计选型很重要，它关系到轧机性能的优劣。 (5) the plate precision is high. According to the working characteristics of rolling mill, thus puts forward higher requirements on roller bearings, bearing load-bearing capacity, high rotating accuracy, high limit speed, simple structure, easy installation, etc. Therefore, according to the requirements and actual conditions of the mill, the design selection of rolling roller bearings is very important, and it relates to the performance of rolling mill. |
