    • A gear cutting machine comprising a tool rotating about a first axis, the first axis being rotatable about a second axis at a first cone-shaped shell or cone, the second axis being rotatable about a second cone-shaped shell or cone about a third axis. There is further provided a gear drive possessing two pairs of bevel gears. The cone apex-cone angles of the bevel gears of one pair of bevel gears are of the same magnitude as the cone apex-cone angles of the bevel gears of the other pair of bevel gears, such cone angles are obtuse, and both of the pairs of bevel gears are connected with one another through the agency of a pair of spur gears.
    • 一种齿轮切割机,包括围绕第一轴线旋转的工具,所述第一轴线可在第一锥形壳体或锥体处围绕第二轴线旋转,所述第二轴线可围绕第三轴线的第二锥形壳体或锥体旋转 。 还提供了具有两对锥齿轮的齿轮传动装置。 一对锥齿轮的锥齿锥的锥锥角与其他锥齿轮的锥齿锥的锥锥角相同,锥角是钝的, 成对的锥齿轮通过一对正齿轮的机构相互连接。
