Title:
REDUCTION GEAR
Document Type and Number:
Japanese Patent JPS54160960
Kind Code:
A
Abstract:
PURPOSE:To obtain any reduction gear ratio by simple structure, by transmitting the positive revolution and reverse revolution of a driving shaft, which is driven by means of a motor periodically repeating positive and reverse revolution and turns in a reciprocative manner, to a driven gear by means of separate partical gears. CONSTITUTION:A cam plate C1 is fixed to driving shaft 2, and a cam plate C2 is loosely fitted. Partical toothed wheels 3, 4 are unified with the cam plate C2, the partical toothed wheel 4 is engaged with a driven toothed wheel 5 by means of the cam plates C1, C2 when the driving shaft 2 turns in the arrow head direction, and the shaft 2 also drops with the lowering of the cam C2 and the partial toothed wheel 3 is engaged with the driven toothed wheel when the shaft turns in the reverse direction. Consequently, the driven toothed wheel rotates in positive or reverse direction only by the difference of the numbers of the teeth of the partial toothed wheels 3, 4. Thus, necessary reduction gear ratio can be obtained without using a number of toothed wheel rows because only the difference of the angle of revolution of a driven shaft by positive revolution and reverse revolution can be transmitted to the driven shaft.
