汽车上的循环球式转向机螺杆的滚珠螺纹加工,多年来一直采用车——磨工艺。该工艺生产率低、成本高、经济效益差,因此对该生产工艺进行改革,已成为转向机专业生产企业的主要任务。作者受有关单位的委托,对EQ140型汽车循环球式转向机螺杆的滚珠螺纹加工采用螺旋横轧工艺进行了试验研究,并取得了满意的结果。 Rolling ball screw steering ball screw on the car, car - grinding process has been used for many years. The process of low productivity, high cost, poor economic efficiency, so the reform of the production process has become the main task of steering machine manufacturing enterprises. The author commissioned by the relevant units, on the ball screw EQ140-type automotive recycling ball screw spiral cross-rolling process using a pilot study and achieved satisfactory results.
