石景山钢铁公司300小型连续式轧机,已用弧形齿接轮代替叉头偏头式万向接轴成功,解决了设备上一项关键问题。这套小型轧机,机械化与自动化程度比较高。原设计是密封式万向接轴,但是,经过几年来的生产实践证明:这种接轴使用寿命很短,需要经常更换,每年消耗很多的铜。而且运转情况也不好,冲击、噪音很大,恶化了设备的工作条件,限制了轧制速度,影响了产量、质量的提高。为了彻底解决这个问题,查阅了很多的国内外资料, Shijingshan Iron and Steel Company 300 small continuous rolling mill has been replaced by the arc gear tooth fork eccentric universal joint success, to solve a key issue on the device. This small mill has a high degree of mechanization and automation. The original design is a sealed universal joint, but, after years of production practice has proved that: this spindles have a short service life, require frequent replacement, consume a lot of copper each year. And the operation is not good, impact, noise, deteriorating the working conditions of the equipment, limiting the rolling speed, affecting the yield, quality improvement. In order to completely solve this problem, access to a lot of domestic and foreign information,
