我们对10L207柴油机调速器传动装置轴(65号轴)进行了改造,二年多来未出现故障。其改造主要有两点: 1.花键尺寸的选择我段花键尺寸为6—7O×62×16; 水城段花键尺寸为6—75×65×16(与400~#轴同); 遵义段花键尺寸为6—65×55×16。我段花键曾用插床加工,误差较大,装配困难,但又无6—75×65×16拉刀,仅有6—70×62×16拉刀。经计算校核,采用这种规格的花键所能承受的最大挤压应力与原设计的渐开线齿形花键损坏时的挤压应力相比较,其安全
We rebuild the 10L207 diesel governor drive shaft (shaft 65) for more than two years without any problems. The transformation of the main two points: 1. The choice of spline size I segment spline size 6-7O × 62 × 16; Shuicheng segment spline size 6-75 × 65 × 16 (with 400 ~ # axis); Zunyi segment spline size 6-65 × 55 × 16. I have spent spline slot machine processing, the error is larger, assembly difficulties, but no 6-75 × 65 × 16 broach, only 6-70 × 62 × 16 broach. After calculation and checking, the maximum compressive stress that the spline with this kind of specification can bear is compared with the extrusion stress when the original design involute tooth-shaped spline is damaged, its safety
