详细分析三种常见的螺旋角定义方法,确定锥形和精加工指形齿轮铣刀的合理螺旋角的定义方法,并给出锥形铣刀合理螺旋角与其它两种螺旋角之间的相互关系。还提出指形铣刀合理螺旋角实用化的三种方法,进而给螺旋槽指形齿轮铣刀的设计与制造提供必要的理论依据和切实可行的设计数据与计算公式。
Three kinds of common methods for defining the helix angle are analyzed in detail, and the method for defining the reasonable helix angle of the tapered and finished finger gear cutter is determined, and the mutual relationship between the reasonable helix angle and the other two helix angles of the cone cutter is given. relationship. Three methods are put forward to practicalize the reasonable spiral angle of finger-milling cutters, and then provide the necessary theoretical basis and practical design data and calculation formulas for the design and manufacture of helical groove finger gear cutters.
