概述
这是在“ X”轴上切割的第一颗牙齿的食齿沟
使用: 用户输入“径向螺距”,“齿数”和“压力角”
注意:模板是为 SolidWorks中的以下全局变量: “直径间距” = 15径向间距 “ NumTeeth” = 45牙齿数 “ PressureAngle” = 15deg压力角
计算的其他值: “附录” = 1 /“直径间距”附录 “ Dedendum” = 1.25 /“ DiametralPitch” Dedendum “ WorkingDepth” = 2 /“ DiametralPitch”工作深度-此处为REF(在建筑模型中未使用) “ WholeDepth” = 2.25 /“ DiametralPitch”整个深度-此处为REF(在建筑模型中未使用) “间隙” = 0.25 /“直径间距”间隙 “ ToothThickness” = 1.5708 /“ DiametralPitch”牙齿厚度-此处为REF(在建筑模型中未使用) “ CircularPitch” = pi /“ DiametralPitch”圆形螺距-此处为REF(在建筑模型中未使用) “ PitchCircle” =“ NumTeeth” /“ DiametralPitch”螺距圆-或-螺距直径 “ OutsideDiameter” =(“ NumTeeth” + 2)/“ DiametralPitch”外径 “ Fillet” =“间隙” * cos(“ PressureAngle”)* tan((90 +“ PressureAngle”)/ 2)圆角 “ AddendumCircle” =“ PitchCircle” +(2 *“ Addendum”)附录圆-或-附录直径 “ DedendumCircle” =“ PitchCircle”-(2 *“ Dedendum”)齿根圆-或-齿根直径 “ BaseCircle” =“ PitchCircle” * cos(“ PressureAngle”)基本圆-基本直径 “ PitchAngle” = 360deg /“ NumTeeth”'俯仰角 “ Alpha” = sqr(“ PitchCircle” ^ 2-“ BaseCircle” ^ 2)/“ BaseCircle” * 180 / PI-“ PressureAngle” Alpha-用于计算Beta “ Beta” =(“ PitchAngle” / 4-“ Alpha”)Beta-用于定义参数方程式驱动曲线的参数 “ Phi” = sqr((“ AddendumCircle” / 2)^ 2-(“ BaseCircle” / 2)^ 2)/(“ BaseCircle” / 2)Phi-用于定义参数方程驱动曲线的参数
“ D1 @ Fillet1” =“ Fillet” “ D1 @ CirPattern1” =“ NumTeeth”
渐开线形式(第一次渐开线)的参数“方程驱动曲线”的参数定义: (“ BaseCircle” / 2)(cos(t +“ Beta” * pi / 180)+ t * sin(t +“ beta” * pi / 180)) (“ BaseCircle” / 2)(sin(t +“ Beta” * pi / 180)-t * cos(t +“ beta” * pi / 180)) 0 “ phi”
渐开线形式(第二渐开线)的参数“方程驱动曲线”的参数定义: (“ BaseCircle” / 2)(cos(-t-“ Beta” * pi / 180)-t * sin(-t-“ beta” * pi / 180)) (“ BaseCircle” / 2)(sin(-t-“ Beta” * pi / 180)+ t * cos(-t-“ beta” * pi / 180)) 0 “ phi”
