METHOD OF PLOTTING GUIDE CURVE OF CYLINDRICAL SURFACE OF FORCE OR HOUSING (VERSIONS) Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used in internal combustion engines, heat machines, pneumatic devices, pumps and hydraulic sets. Proposed method of plotting guide curve of cylindrical surface of rotor or housing includes describing of curve by means noncentral slider-crank mechanism with energy parameters A(λ, ξ)≠2, A is energy parameter of mechanism, λ- is relative value of slider mechanism connecting rod, ξ- is relative value of distance from axis of slider guide to center of axis of rotation of crank or mechanism including crank with different stroke as to angle of crank turning, and guide curve asymmetrical relative to axis Y of system of coordinates is described by one of points of mechanism links, points of guide curve being determined using following equations or and also equations or . EFFECT: simplified designing, enlarged design capabilities as compared with existing ones. 3 cl, 20 dwg
