圆孤齿圆柱齿轮和圆孤齿齿条的传动,能使震动减弱,噪音降低;节省材料,成本低廉,还可提高承载能力,延长其使用寿命。克拉玛托尔斯克工业学院研究出一种新的切齿机床和自动分度装置来铣削孤形齿。用一个铣刀头可对圆柱齿轮、圆锥齿轮和齿条进行铣削加工。当用万能切齿铣刀头1(图1)铣削圆柱齿轮时,铣刀头1的轴线与假想齿条2节线 The transmission of circular and spur gear and circular orotate rack can reduce the vibration and reduce the noise; save material, low cost, but also improve the carrying capacity and extend the service life. Klamathorsk Institute of Technology has developed a new gear cutting machine and automatic indexing device for milling splined teeth. Cylindrical gears, bevel gears and racks can be milled with a milling head. When milling the spur gear with the universal cutter head 1 (Figure 1), the axis of the cutter head 1 is aligned with the imaginary rack 2-section line
