一、引言某工程研究院一高精度运转轴,为保证轴的不圆度的高精度要求,采用高强度钢材质的薄壁空心轴,内腔注入高压油液。转动轴的空间工作温度为85℃,长期工作时轴
I. INTRODUCTION An engineering institute has a high-precision running shaft. In order to ensure high-precision non-roundness of the shaft, a thin hollow shaft made of high-strength steel is used to inject high-pressure oil into the lumen. Rotary shaft space working temperature of 85 ℃, long-term work axis
