汽车、拖拉机齿轮的内花键,一般都采用内花键大径定心,内花键经渗碳淬火后不便进行加工。因此,要使齿轮内花键达到技术要求,减小齿轮内花键畸变尤为重要。现将几种减小齿轮内花键畸变的方法介绍如下: 1.花键拉刀冷、热公差配合 生产实践证明,内花键渗碳淬火变形规律一般趋向收缩变小,根据内花键的变形规律,不能采用标准花键拉刀,应采用非标准热缩型花键拉刀。通过试验可以确 Car, tractor gear internal spline, are generally used within the large diameter spline centering, internal spline quenching after carburizing inconvenience for processing. Therefore, to make the gear spline to meet the technical requirements, reduce gear spline distortion is particularly important. Now several ways to reduce the spline gear distortion are described below: 1. Spline broach cold and heat tolerance with production practice has proved that the internal spline carburizing quenching deformation generally tends to shrink smaller, according to the internal spline Deformation laws, can not use the standard spline broach, non-standard shrinking spline broach should be used. By testing can be true
