DEVICE FOR ROTATIONAL MOTION CONVERSION INTO RECIPROCAL Russian patent published in 2015 - IPC F16H25/00 

FIELD: machine building.

SUBSTANCE: device for rotational motion conversion into reciprocal contains casing, slider, drive shaft, additional slider, driven element and retainer. On the side surface of the slider a closed screw groove is made, in it the draw-bars are installed to half of their height. Along the slider axis the drive shaft is located, it makes rotational movement and transfers it to the slider via spline joint movable along the slider axis. Second half of the draw-bars located in the closed screw groove of the slider, and projecting beyond its limits, if fixed in the retainer installed in the ring groove. The retainer is kinematically linked with the drive element ensuring rotation and fixing of the retainer with draw-bars relatively to the casing, thus resulting in reciprocating movement of the slider additionally to the rotational movement. At the slider end opposite to the drive shaft a cylindrical cavity is made, in it with possibility of movement along the axis the additional slider is installed, at that on the external cylindrical surface of the additional slider the closed screw groove is made. Rotation of the additional slider relatively to the casing is limited by the spline joint.

EFFECT: increased efficiency.
