PURPOSE:To carry out a continuously variable transmission with a low vibration and a high efficiency by setting the shape of the both meshed revolution parts so that the function of the absolute value of the revolution speed ratio of the first and second noncircular gears for the angular displacement and the differential value vary continuously. CONSTITUTION:As for the first - third noncircular gears 11, 21, and 31 fixed on the first - third rotary shafts 10-30, each meshing pitch curved line 12a, 12b, 13a, 13b, 22a, 22b, 23a, 23b is meshed, and the revolution supplied from the second rotary shaft 20 is transmitted to the third rotary shaft 30, and the continuously variable transmission is performed by varying the phase angle pi+alpha of the third rotary shaft 30 for the second rotary shaft 20. In this case, the absolute value of the radio omega2/omega1 and omega1/omega3 of the revolution speed of the roncircular gears 11, 21, and 31 is set as the function of the angler displacement theta of the first noncircular gear 11, and the shape of the meshed pitch curved line 12a, 12b and 22a, 22b, and 13a, 13b, and 32a, 32b is set so that the value of the function and the differential value for the value theta are continuously varied. Thus, the continuously variable transmission can be carried out with a low vibration and a high efficiency. |
