Planetary gear magnification belt type continuously variable transmission
专利汇可以提供Planetary gear magnification belt type continuously variable transmission专利检索，专利查询，专利分析的服务。并且PURPOSE: To expand the width of transmission in a broad range, by making it possible to magnify both the speed output from an internal gear when the force is input from a sun gear, and the speed output from the sun gear when the force is inversely input from the internal gear, larger than the width of transmission controllable by only a variable pulley of a continuously variable transmission.
CONSTITUTION: When a shaft 3a is rotated at the ratio of the contact radius of a transmission belt 10 and a variable pulleys 8a and 8b 1:1, and if the diameters of a belt groove 3b and an intermediate pulley 7 are equal, a sun gear 1 is also rotated at the same speed. when the contact radius of the variable pulley 8a with the belt 10 is made larger than that of the variable pulley 8b by a control screw 9, the rotation speed of the sun gear 1 is reduced. When the number of teeth of the sun gear 1 and an internal gear 3 are made A and B, and the relative speed ratio of the internal gear 3 and a carrier 4 is made B/(A+B), the rotation speed of the sun gear 1 is made zero. In such a composition, the narrow width of the continuously variable transmission control of the variable pulleys 8a and 8b can be magnified extensively, and the width of the transmission can be extended in a broad range.
