| 摘要 |
A gearing system for a lathe is shiftable from a first position, in which conical gear wheels (16, 25, 26, 36) engage each other with play, to a second position, in which the wheels engage each other without play. Reduced wear is achieved in the first position. High precision is achieved in the second position. Preferably, the system also has parallel-toothed gear wheels (15, 24, 35) which are engaged when the conical gear wheels are disengaged. |
