摘要： A chamfer hob for and a method of providing a chamfered end and having an identical chamfer angle at both a front face and a back face of a gear including a shaft, a plurality of helical cutting vanes extending radially outwardly from the shaft, such that the radially outward surface of the cutting vanes defines a hob diameter, and a hob radius, a predetermined radial width of the desired chamfer and a depth of chamfer, such that the chamfering is done on both faces of the gear teeth ends resulting in a uniform chamfer around the periphery of the complete gear tooth. The method includes the steps of providing a blank gear die, including a gear shaft and a disk having a front face distally disposed from the gear shaft and back face proximally disposed to the gear shaft, each of the front and back faces having gear, providing a gear hob and a chamfer hob on a single hob spindle, the chamfer hob having a plurality of helical cutting vanes extending radially outwardly from the hob shaft, such that the radially outwardly extending surface of the cutting vanes, mounting the gear blank on a mount, mounting the hob spindle, including the gear hob and the chamfer hob, on a mounting device for rotation therewith, bringing the gear hob in proximity to and in contact with the edges of the gear blank so as to form gear teeth on the gear blank, bringing the chamfer hob in proximity to and in contact with the edges along the front face of the gear teeth formed in the preceding step so as to produce a uniform chamfer around the edges of the gear teeth and bringing the gear hob in proximity to and in contact with the edges along the back face of the gear teeth formed so as to produce a uniform chamfer around the edges of the gear teeth.

摘要翻译： 一种倒角炉和一种提供倒角端并在包括轴的齿轮的前表面和后表面上具有相同的倒角的方法，多个螺旋形切割叶片从轴向径向向外延伸，使得 切割叶片的径向外表面限定了滚刀直径，滚刀半径，所需倒角的预定径向宽度和倒角深度，使得在齿轮齿端部的两个面上进行倒角导致均匀的倒角 在整个齿轮齿周围。 该方法包括以下步骤：提供一种空白齿轮模具，包括齿轮轴和盘，其具有从齿轮轴向远侧设置的前表面和近侧设置在齿轮轴上的后表面，每个前后面具有齿轮，提供 在单个滚刀轴上的齿轮滚刀和倒角滚刀，所述倒角滚刀具有从所述滚刀轴径向向外延伸的多个螺旋切割叶片，使得所述切割叶片的径向向外延伸的表面将所述齿轮坯件安装在安装件 ，将包括齿轮滚刀和倒角滚刀的滚刀主轴安装在安装装置上以与其一起旋转，使齿轮滚刀靠近齿轮坯料的边缘并与齿轮坯料的边缘接触，以在齿轮坯料上形成齿轮齿 将倒角滚刀沿着前一步骤中形成的齿轮齿的前表面接近并接触边缘，以便在齿轮齿的边缘周围产生均匀的倒角，并带来 齿轮滚刀靠近并沿齿轮齿的后表面与边缘接触，以便在齿轮齿的边缘周围产生均匀的倒角。
