CONRODLESS MECHANISM OF PISTON MACHINE Russian patent published in 2024 - IPC F01B9/02 F02B75/32 F16H21/18 

FIELD: machine building.

SUBSTANCE: invention can be used in mechanisms for converting reciprocating motion into rotary motion of internal combustion engines, compressors and pumps. Conrodless mechanism of piston machine comprises opposed cylinder-piston groups (10), (11), housing (1), working shaft (3) and crankshaft (4). Cylinder-piston groups (10), (11) are interconnected by rods (9), axes of which are located at an angle to each other. In housing (1) on bearings (2) there is working shaft (3) with power takeoff in its middle part. Working shaft (3) has hole (6) shifted from axis of rotation of working shaft. Crankshaft (4) is seated in hole (6) with possibility of rotation. Crankshaft (4) has at different ends two opposed journals engaged via bearings with rods (9). Crankshaft (4) at both ends is equipped with elements (12) and (13) rigidly connected to the shaft. These elements (12) and (13) provide external fit of crankshaft (4) on working shaft (6) by means of bearings (18). Two oppositely located journals (15) are made on these elements.

EFFECT: possibility of seating the crankshaft on rolling bearings and reducing the overall dimensions of the conrodless mechanism.
