GEAR MECHANISM FOR CONVERTING ROTATIONAL MOTION INTO AN UNEVEN ONE Russian patent published in 2021 - IPC F16H3/44 F16H19/02 

FIELD: mechanical engineering.

SUBSTANCE: gear mechanism for converting rotational motion into an uneven one contains a case, in which an input and output shafts are coaxially mounted, an elliptical gear wheel mounted on the output shaft, an elliptical gear wheel mounted on the input shaft and engaged with an elliptical gear wheel of the same size fixed on an intermediate shaft, the second elliptical gear wheel is fixed on the intermediate shaft, which is engaged with the elliptical gear wheel on the output shaft of the same size. The minor semi-axis of the first pair of elliptical wheels may differ from the minor semi-axis of the second pair, and major semi-axes of all elliptical wheels are the same. All elliptical wheels are mounted on their shafts in such a way that the axis of rotation of the shaft passes through a focus point of a dividing ellipse.

EFFECT: invention provides simplification and reduction of the structure, as well as the possibility to adjust the coefficient of unevenness of the output link.
