Publication number: 20170328447Abstract: Transmission mechanism has set of two composite sprockets (5, 5), each having pinion sprockets (20) supported movably in radial direction with respect to rotation shaft (1) inputting or outputting power and movement mechanism radially moving pinion sprockets (20) in synchronization with each other while maintaining equidistance of pinion sprocket (20) from shaft center (C1) of rotation shaft (1), and chain (6) wound around two composite sprockets. Transmission ratio is changed by changing circumcircle radius that is radius of circle encircling and circumscribing all the pinion sprockets (20). Each guide rod (29) has first guide rod (291) guiding chain (6) all the time regardless of circumcircle radius size, and second guide rod (292) guiding chain (6) at least when circumcircle radius is a maximum and positioned at radial direction inner side with respect to first guide rod (291) when circumcircle radius is a minimum. With this, ratio coverage can be expanded.Type: ApplicationFiled: December 8, 2015Publication date: November 16, 2017Applicant: JATCO LtdInventor: Hiroshi TANGE

Publication number: 20170328448Abstract: A transmission mechanism has a set of two composite sprockets, each having pinion sprockets (210) supported movably in a radial direction with respect to a rotation shaft 1 that inputs or outputs power and a movement mechanism radially moving the pinion sprockets (210) in synchronization with each other while maintaining equidistance of the pinion sprocket (210) from a shaft center (C1) of the rotation shaft 1, and a chain wound around the two composite sprockets. Transmission ratio is changed by changing a circumcircle radius that is a radius of a circle encircling and circumscribing all the pinion sprockets (210). The pinion sprocket (210) is formed into a sector gear shape having a teeth portion (212) that is arranged along a circumference of a minimum radius circumcircle (A1) and meshes with the chain.

Publication number: 20170184184Abstract: Transmission mechanism has interlock mechanism (60) interlocking widening of circumcircle radius of one composite sprocket (5) and reduction of circumcircle radius of the other composite sprocket (5) during transmission ratio change. Interlock mechanism (60) is configured so that in a case where transmission ratio is changed toward uniform transmission ratio at which rotation speeds of two rotation shafts (1, 1) are the same, if actual chain length, which is real length of chain with respect to geometrical chain length that is length of ideal chain wound around two composite sprockets (5, 5) without excess and deficiency of chain length when widening and reduction are carried out by a same amount, is greater than predetermined length, reduction amount is set to be smaller than widening amount, while if the actual chain length is not greater than the predetermined length, the widening and reduction amounts are set to be the same.Type: ApplicationFiled: February 26, 2015Publication date: June 29, 2017Applicant: JATCO LtdInventor: Hiroshi TANGE
