高速线材生产线的主要特点是轧机连续运行的可靠性高。由于单位产量高,要求轧机使用的轴承在规定的检验期间必须比普通轴承具有更高的可靠性。轧机轴承必须满足高速和高冲击条件下的连续运行要求。对于生产高速轧机轴承的制造商来说,轴承能否经受住持续生产和禁止轴承损坏是一个至关重要的标准。
由于高速线材轧机的工作特点,对配套轴承的要求更为严格,轧机转速高,轴承承受的载荷大,冲击力大,轴承质量必须可靠、高。
嘉裕生产的高速线材轧机轴承在高速线材精轧机上得到了稳定的应用,与美国、德国生产的轴承相比,质量更高,价格更有竞争力。




关键技术
1.考虑到润滑、离心力和滑移以及重载造成的冲击力。
2.可靠性更高
3.改进的机笼设计
4.改进沟槽曲线
