我厂主要生产推土机配件,其中进口机型配件中有一种双模数、变位、短齿、渐开线齿形花键轴是外园底锥。这种花键轴的形状是:外园柱形,槽底沿轴线有锥度,键宽在同一园柱表面上保持不变。其特点是可以调节花键底径配合松紧程度,特别是用在大功率、大负荷的工作条件下最为有利。由于这种花键轴的特殊性,必须要有一种特殊的加工方法和一台专 I plant mainly produces bulldozer parts, of which imported models have a dual-modulus parts, displacement, short teeth, involute tooth-shaped spline shaft is the outer cone. The shape of this spline shaft is: external cylindrical, groove bottom taper along the axis, the key width remains unchanged on the same cylindrical surface. Its characteristics are to adjust the spline diameter with the tightness, especially in the high-power, high-load conditions most favorable. Due to the special nature of this spline shaft, there must be a special processing method and a special
