一、分析在卡尔别克型伞齿轮刨末上可以加工螺旋齿(切线齿)伞齿轮,这是根据平面齿轮和伞齿轮的啮合原理进行的:切刀的主切削刃形成了假想平面齿轮的齿,而伞齿轮毛坯的轴线与假想平面齿轮的节平面所夹之角等于所切伞齿轮的节锥角(?),如[图一]所示。在切削过程中,假想平面齿轮的节平面和所切伞齿轮的节锥面相互作纯滚动;这样,我们就可以利用标准压力角的切刀来加工各种倾斜角和齿根角的螺旋齿伞齿轮,而不必修正切刀的压力角了(所谓刀号修正)。在这种平面齿轮的节平面内,齿线是直线形
1. Analysis Bevel gears (tangential teeth) can be machined at the end of a bevel gear of the Kalbike type according to the meshing principle of a bevel gear and a bevel gear: the main cutting edge of the knife forms the imaginary face gear teeth , While the angle between the axis of the bevel gear blank and the nodal plane of the imaginary plane gear is equal to the section cone angle (?) Of the bevel gear, as shown in Figure 1. During the cutting process, the plane of the imaginary face gear and the conical face of the bevel gear roll purely with respect to each other; thus, we can use standard pressure angle cutters to machine helical umbrella umbrellas of various angles of inclination and root angle Gear without having to correct the pressure angle of the cutter (the so-called cutter correction). In this plane gear nodal plane, the tooth line is straight
