汽车中传递扭矩并有少量轴向移动的地方,大多采用花键连接。模数在1mm以下的花键称为小模数花键。随着轿车、轻型车生产的发展,小模数花键的使用点在不断增加。目前国内花键一般采用滚齿机或铣床加工,单件工时在5—10分左右,适应不了汽车生产发展的需要。国际上有用搓挤、正挤、滚挤小模数花键的先进工艺。搓挤、滚挤需要比较昂贵的设备投资,而正挤工艺只需要
In the car where torque is transmitted and where there is a small amount of axial movement, splines are often used. Spline modulus below 1mm called small modulus spline. With the development of the production of cars and light vehicles, the use of small modulus splines is constantly increasing. At present, the general use of domestic spline gear hobbing machine or milling machine processing, single part-time about 5-10 minutes, can not meet the needs of the development of automobile production. Useful international squeeze squeeze, squeeze, squeeze squeeze small modulus spline of the advanced technology. Rubbing, rolling crowding requires more expensive equipment investment, and just squeeze the process
