采煤机齿轮工况条件恶劣,传动可靠性要求较高,受空间条件限制,常采用变位齿轮和渐开线花键结构。为保证其性能、精度,在渗炭、淬火后加工花键。为此,对普通高速钢制成的渐开线花键刀具进行表面渗硼处理,取得了较好的加工效果,本文对其工艺过程作了详细介绍。 Shearer gear conditions harsh conditions, higher transmission reliability requirements, subject to space constraints, often using variable gear and involute spline structure. In order to ensure its performance, accuracy, carburizing, quenching after the processing spline. To this end, the ordinary high-speed steel made involute spline cutter surface boronizing treatment, and achieved a better processing effect, this paper made a detailed introduction of the process.
