MECHANICAL GEAR SPEED VARIATOR OF PLANETARY TYPE WITH CONSTANT MOVEMENT AND SMOOTH CHANGE OF GEARING Russian patent published in 2018 - IPC F16H3/76 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Mechanical gear speed variator of a planetary type with constant engagement and a smooth variation of the gearing contains an input shaft, a shaft with a conical gear fixed to it, which is in mesh with a ring gear of a toroidal shape and a wheel fixed immovably in the body of the device. Device also comprises an output shaft extending inside the stationary wheel and fixed to the body of the device, a hinge of equal angular velocities, mounted on the output shaft and having a disc with springs that press the toothed ring of the toroidal shape to the conical shaped gear, a regulator of revolutions fixed to the input shaft, arranged to move along the axis of the device and connected through a rod with a disk.

EFFECT: it is ensured the construction of a variator, which is easy to manufacture and operate.
