汽车转向器中的球面蜗杆,形状复杂,齿面光洁度要求较高。我厂利用一台报废的车床,改制成蜗杆滚压机。其特点是改装简便,辗光面积大,班产60件,适合中、小批生产单位使用。动作说明由1.7千瓦电动机经减速后传至车头主轴,主轴转速为35转/分,在主轴内锥孔装一支带花键的芯轴,在芯轴端套上一只定心用锥套,工件即以花键为传动,以内锥套为定位,以尾顶针顶紧,随主轴转动而转动,并由工件1带动辗轮2摆动。
Spherical worm in the steering gear, complex shape, tooth surface finish higher. I use a scrap factory lathe, transformed into worm roller press. It is characterized by easy modification, rolling area, production of 60 classes, suitable for medium and small batch production units. Action Description 1.7 kW motor was decelerated to the front spindle, the spindle speed of 35 rev / min, installed in the spindle tapered bore with a splined mandrel, the core end of the sleeve with a centering taper sleeve , The workpiece that is spline transmission, the positioning of the inner sleeve to the tail pin top tight, with the rotation of the spindle rotation, driven by the workpiece 1 roller 2 swing.
