滑块式万向接轴由于允许倾角较大,工作平稳,能传递的扭矩范围较广,维修方便,故广泛应用于轧辊调正范围较大的轧钢机上。为了延长滑块和叉头的使用寿命,降低各种消耗,除在叉头的材质、表面硬度采取强化措施,探索青铜滑块的代用材料外,润滑问题也是至关重要的。我们1985年开始,对φ1100初轧机滑块式万向接轴的润滑与密封存在的问题,采取不同的油脂和密封方法,进行多次试验,初步取得了一定的成果,介绍如下。
Sliding universal joint shaft allows larger inclination, stable work, wide range of torque transmission, easy maintenance, it is widely used in a wide range of roll to be adjusted on the rolling mill. In order to extend the service life of sliders and prongs, and to reduce various kinds of consumption, lubrication problems are also crucial in addition to the material of the prongs, the reinforcement of the surface hardness, and the exploration of substitute materials for the bronze sliders. We began in 1985, φ1100 first rolling mill universal joint shaft lubrication and sealing problems, using different methods of grease and sealing, a number of tests, initially achieved some results, introduced below.
