FIELD: machine building. ^ SUBSTANCE: mechanism consists of unidirectional rotating cam-driving link installed in case, of driven link, of control arm, and of device of conversion of unidirectional rotation of cam into oscillating rotation of driven link with smooth change of peak-to-peal value by means of control arm. The device of conversion includes two-arm rocker installed in the case and contacting the cam; the rocker is kinematically coupled with the driven link. The device further includes a conic tooth gear, a lever with a conic tooth sector, and a winker installed in the case and turned by means of the control arm. The winker is equipped with journals whereon there is secured the lever. Also, a circular shaped slot contacting the lever is made in the two-arm rocker. A conic tooth sector of the lever is coaxial to the journals, while the tooth gear is coaxial to rotary axis of the winker, is engaged with the conic tooth sector and corresponds to the driven link of the mechanism. ^ EFFECT: simplified design and improved operational characteristics of mechanism. ^ 15 dwg |
