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. |
