伞齿轮鉋削原理伞齒輪鉋刀是用来鉋削直齒伞齒輪的。其工作原理如下: 伞齒輪与平面伞齒輪相嚙合转动时,二者间存在有下列的关系: ω_3/ω_κ=sinδ_κ/sinδ_3 (1) 式中:ω_3、ω_κ为伞齒輪与平面伞齒輪的角速度,δ_3、δ_κ为伞齒輪与平面齒輪的节锥顶角。假使把平面伞齒輪换成切削刀具,用齒輪胚代替伞齒輪,并且使刀具沿[图一]箭头方向来回运动,则刀具与伞齒輪间的相对运动仍旧可以用公式(1)来表示,并且可以在輪胚上切出所需要的齒形。此时由于切削刀具系代替平面伞齒輪,所以刀
Bevel gear planing principle Bevel gear planing machine is used to planing straight bevel gear. The working principle is as follows: When the bevel gear meshes with the flat bevel gear, there exists the following relationship: ω_3 / ω_κ = sinδ_κ / sinδ_3 (1) where ω_3 and ω_κ are angular velocities of the bevel gear and the plane bevel gear , δ_3, δ_κ for bevel gear and flat gear section cone apex angle. If the flat bevel gear is replaced by a cutting tool and the gear embryo is used instead of a bevel gear and the tool is moved back and forth in the direction of the arrow in FIG. 1, the relative movement between the tool and the bevel gear can still be expressed by formula (1) You can cut out the required profile on the wheel. At this point because the cutting tool instead of flat bevel gear, so the knife
