CRANK SLIDER MECHANISM OF A PISTON MACHINE Russian patent published in 2022 - IPC F16H21/16 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. The crank-slider mechanism of the piston machine contains a composite crank, consisting of two parts, the first and second, while a connecting rod journal is connected to them, and a connecting rod journal with a connecting rod bearing mounted on main bearings, a piston with the possibility of reciprocating motion, a connecting rod kinematically connecting the piston to the crank and having an upper head kinematically connected by a piston pin to the piston, and also a lower head having a slider made in the form of a part of an annular sector, kinematically connected with the connecting rod journal and with annular elements made with the possibility of limiting the radial displacement of the slider relative to the connecting rod journal of the crank and enclosing the slider. The bearing mounted on the connecting rod journal is made in the form of a rolling bearing, the surface of the outer cage of which is kinematically connected with the inner cylindrical surface of the slider and is made with the possibility of its rotation on the outer race of the rolling bearing of the connecting rod journal, and ring-shaped elements are installed on the slider, mated with the outer cylindrical surface of the slider.

EFFECT: simplification of the mechanism design.
