用母线为直线的砂轮刃磨螺旋槽滚刀时,从齿根到齿顶的容屑槽前面上形成凸面。凸起量的大小将随螺旋槽倾角的增加而增加。为了使前面径向性偏差不致超差,对砂轮必须进行成型修正。为此,则需要制造适当的夹具,研究砂轮截形的计算方法。威特比斯克齿轮机床、磨床、刃磨机床专业设计局设计和研究了在新型号的半自动滚刀开刃磨床上使用的砂轮成型修正机构,保证得到那段正弦曲线,用以近似地代替所计算的砂轮截形。图1为装在3A662型半自动机上的机构试验装置。在固定的壳体中,装有两对锅轮付,平尺
When grinding a helical groove hob with a rectilinear grinding wheel, a convex surface is formed on the front of the chip flute from the tooth root to the tooth tip. The amount of protrusion will increase with the inclination of spiral groove. In order to make the front radial deviation does not exceed the tolerance, the wheel must be shaped to correct. To do this, you need to create the appropriate fixture to study the calculation of wheel truncation. Wittbiske Gear Machine, Grinder, Sharpening Machine Specialist Design Bureau has designed and researched the grinding wheel dressing correction mechanism used in the new model semi-automatic hob edger grinder to ensure that the sinusoidal curve is obtained to approximately replace Calculated wheel truncation. Figure 1 is installed in the 3A662 semi-automatic machine test mechanism. In a fixed shell, with two pairs of pots pay, flat feet
