一、拨义加工方法 此类工件主要使用於变速机构中,A孔与操纵拉杆结合,当其运动时利用 义之两端面。驱动花键齿轮以达到变换齿轮之目的。A孔距 义之距离(1尺寸)一般约为150-250公厘(如图1)。主要技术条件为加工时应保证 义对A孔轴心之垂直性,及A孔与 义间之杆部根据机构需要有一 First, the dialing processing methods Such parts are mainly used in the variable speed mechanism, A hole and the steering rod combined with the use of its meaning when the two ends of the movement. Driven spline gear to achieve the purpose of changing gear. The distance of A hole distance (1 size) is generally about 150-250 mm (Figure 1). The main technical conditions for the processing should ensure that the meaning of the Y axis perpendicular to the hole, and A hole and the rod according to the agency needs a
