The invention provides an eccentric swinging type reducer series with further reduced manufacturing cost of the entire eccentric swinging type reducer. The eccentric swining type reducer series is composed of multiple reducers of multiple models set correspondingly with respect to the magnitudes of transmission torque. The reducers (10a, 10b) in the series include internal gears (12a, 12b), first external gears (14a, 14b), second external gears (16a, 16b), multiple crankshafts (18a, 18b) which are disposed in positions deviating (L1) from axes (O3) of the inner gears to swing the first outer gears and the second outer gears, and crankshaft gears (30a, 30b) which outputs power from input sides to the crankshafts. Outer splines (42a, 42b)for connecting the crankshaft gears are formed at ends of the crankshafts and arranged between the reducers (10a, 10b) of different modesl (W1, W2). The size/shape of each outer spline is set to be universal. |
