现代化轧钢机的工作速度很高,要轧制尺寸精度高而且尽可能宽的材料,这就对滚动轴承提出了更高的要求,要求它能在负荷日益加重的运转条件下工作。由Timken滚柱轴承公司研究制成的平衡对称式轧辊辊颈用滚柱轴承有助于解决上述问题。TQO型四列锥形滚柱轴承是最常用的一种,它包括2个双列锥形架,1个双列外套圈,2个单列外套圈以及2个外套圈分隔圈和1个锥形架分隔 Modern rolling mills operate at high speeds and require the rolling of highly dimensioned and widest possible material, which places a higher demand on rolling bearings and requires them to work under increasingly loaded operating conditions. The balanced symmetrical roll-neck roller bearings made by Timken Roller Bearings Research can help solve these problems. TQO type four-row tapered roller bearings are the most commonly used one, which includes two double-row conical frame, a double row outer ring, two single row outer ring and two outer ring ring and a cone Frame separated
