Disclosed is a flexibly engaged continuously variable transmission gearbox, comprising a power transmission mechanism, wherein through the rotation of an input shaft conical roller (1), the power drives five segmental flexible input sprockets (2) which are slidably matched in five equally spaced T-slots on the surface of the input shaft conical roller (1) to rotate, then the segmental flexible input sprockets (2) drive tooth-shaped chains (3) engaged with them to perform transmission and drive five segmental flexible output sprockets (4) which are slidably matched in the five equally spaced T-slots on the surface of an output shaft conical roller (5) to rotate, and the five segmental flexible output sprockets (4) drive the output shaft conical roller (5) to rotate for outputting the power; and a speed change mechanism, wherein the rotating speed is adjusted in such a way that the rotation of a speed adjusting lead screw (11) is used to drive an adjusting nut idler wheel (17) matched with same to move in a straight line, and then the adjusting nut idler wheel (17) drives the tooth-shaped chains (3) and the segmental flexible sprockets to make translational motions at different engaging diameter positions on the surfaces of the input shaft conical roller and the output shaft conical roller, for getting different rotating speeds, to achieve the rotating speed required by the output shaft conical roller (5). |
