我厂为适应汽车生产需要,自行设计制造了伞齿轮展成铣齿机,每班可加工行星齿轮40个或半轴齿轮24个。这台机床的切齿最大模数为7毫米,最大节锥长度120毫米,根锥角调整范围为20～60°,铣削齿轮最大直径208毫米。机床长1500毫米,宽2000毫米,高1000毫米。机床由铣头和摇台两部分组成。铣头的传动系统如图1所示。电动机2经皮带轮1带动刀盘8转动,并经伞齿轮9带动 I plant to meet the needs of automobile production, design and manufacture of their bevel gear into a milling machine, each class can process planetary gear 40 or 24 -axis gear. The maximum cutting modulus of this machine is 7 mm, the maximum pitch cone length is 120 mm, the root taper angle is adjusted from 20 to 60 °, and the maximum diameter of the milling gear is 208 mm. Machine length 1500 mm, width 2000 mm, height 1000 mm. The machine consists of a milling head and a cradle. Milling head transmission system shown in Figure 1. The motor 2 rotates the cutter head 8 via the pulley 1 and is driven by the bevel gear 9
