PURPOSE:To improve efficiency, by braking a shaft having an increased speed and a low torque by means of a frictional braking material, and controlling the shaft of a surface driving gear, etc. by an independent power. CONSTITUTION:A cross-shaft type synclinal gear mechanism is formed by a surface driving gear 1, a synclinal gear 2 and a surface driven gear 4 to drive a motor M1 directly connected to an input shaft S1. Although same directional torque of an inclined shaft 3 and an output shaft S4 of the synclinal gear mechanism is increased in proportion to a rotational speed, output torque of the synclinal gear mechanism with a large reduction ratio as in the preferred embodiment is reduced by an amount of efficiency. One shaft S3 of the surface driving gear 1 of the cross-shaft type synclinal gear mechanism for the motor M1 is connected through helical grear train 6, 7 and 8 to the shaft S5 of a surface driven gear 14 of an independently formed speed-increasable synclinal gear mechanism. The braking plate 9 of an electromagnetic brake MB is fixed to the inclined shaft S6 of a conical rocking member 13. |
