这openscad脚本提供模块为直齿锥齿轮。它有一些重大的改进，在原有剧本thingiverse.com事：3534。它采用了直齿圆柱齿轮的命名代码从theotherrob github.com / theotherrob /症与我自己的代码生成渐开线齿。锥齿轮也是我自己的工作。也谢谢埃尔默尔一些增强我原齿轮脚本thingiverse.com：：3547。
改进包括锥齿轮模块，反弹设置，参数化的一些方面的渐开线曲线和整个牙齿一代避免的一些问题，^初的剧本中有一个半镜像时齿。
提供的补充交易日志不应直接使用，但相反的例子可以做什么的参数化脚本。
参数化渐开线直齿轮采取下列参数：
齿数
循环音高或经节：控件大小的牙齿（因而大小的齿轮）。
压力角：控制形状的牙齿。
清除：之间的差距，根之间的牙齿和牙齿上的一个点啮合齿轮。
齿轮厚度：厚度的齿板。
轮缘厚度：厚度的齿轮边缘（包括牙齿）。
宽轮辋：径向距离根的牙齿边缘内。
轮毂厚度：厚度部分周围的孔。
轮毂直径
孔直径：大小孔的中间
界：一些圆孔削减在齿板。
反弹：空间之间的这本回齿轮齿和前其啮合齿轮的齿齿轮时，正确地从它间距。
旋转：使斜齿轮。
渐开线方面：一些面一侧的渐开线齿形。如果这是略将1 / 4 $新生力量。如果没有设置为新生力量，这将是5。
参数化渐开线齿锥齿轮（锥形）采取下列参数：
齿数
锥距离：距离从音高尖外圆直径。
宽度：牙齿的长度。
外循环音高：节圆直径在外面。
压力角：定义形状的牙齿。
清除：差距冰山的牙齿上的一个齿轮和根的牙齿上另一个啮合齿轮。
孔直径大小的孔在中间。
齿轮厚度：厚度的圆锥齿轮背锥齿轮完成（见下）。
反弹：使牙齿宽度较小，使齿间间隙的齿轮正确间隔允许制造公差。
渐开线直齿圆柱齿轮方面：如。
完成指定锥齿轮平面（0）或圆锥齿轮背锥（1）。如果你不指定这个参数，你会得到一个单位齿间距角度小于45度，背锥齿轮间距大于45度角。实例表明两个小齿轮是一个单位。
更新：5.0实现隙锥齿轮（这不是工作在4.0）。

Parametric Involute Bevel and Spur Gears
This OpenSCAD script provides modules for both Spur and Bevel Gears. It has some major enhancements over my original gear script thingiverse.com thing:3534. It uses some of the spur gear nomenclature code from TheOtherRob github.com / TheOtherRob / MCAD with my own code for generating the involute teeth. The bevel gear is also my own work. Thanks also to elmom for some enhancements to my original gear script thingiverse.com : thing : 3547.
Enhancements include the Bevel gear module, backlash settings, parameterised number of facets for the involute curve and whole of tooth generation to avoid some of the issues the original script had when mirroring a half tooth.
The STLs provided are not intended for direct use, but instead show examples of what can be done with the parametric script.
Parametric Involute Spur Gears take the following parameters:
number of teeth
circular pitch or diametral pitch: controls the size of the teeth (and hence the size of the gear).
pressure angle: controls the shape of the teeth.
clearance: The gap between the root between teeth and the teeth point on a meshing gear.
gear thickness: the thickness of the gear plate.
rim thickness: the thickness of the gear at the rim (including the teeth).
rim width: radial distance from the root of the teeth to the inside of the rim.
hub thickness: the thickness of the section around the bore.
hub diameter
bore diameter: size of the hole in the middle
circles: the number of circular holes to cut in the gear plate.
backlash: the space between this the back of this gears teeth and the front of its meshing gear\’s teeth when the gear is correctly spaced from it.
twist: for making helical gears.
involute facets: the number of facets in one side of the involute tooth shape. If this is omitted it will be 1/4 of $fn. If $fn is not set, it will be 5.
Parametric Involute Profile Bevel (Conical) Gears take the following parameters:
number of teeth
cone distance: The distance from the pitch apex to the outside pitch diameter.
face width: The length of the teeth.
outside circular pitch: The circular pitch at the outside pitch diameter.
pressure angle: Defines the shape of the teeth.
clearance: Gap between the tip of the teeth on one gear and the root of the teeth on another meshing gear.
bore diameter: The size of the hole in the middle.
gear thickness: The thickness of the gear for bevel gear back cone finish (see below).
backlash: Makes the tooth width smaller to make a gap between teeth of correctly spaced gears to allow for manufacturing tolerances.
involute facets: As for spur gears.
finish: Specify either bevel gear flat(0) or bevel gear back cone(1). If you don’t specify this parameter you will get a flat gear for pitch angles less than 45 degrees and a back cone gear for pitch angles greater than 45 degrees. The example shows both with the small gear being the flat one.
Update: v5.0 Implements backlash for bevel gears (This was not working in v4.0).
