SYSTEM OF MASSES OF OPPOSITE ROTATION TO BE USED WITH ROW FOUR-CYLINDER INTERNAL COMBUSTION ENGINE FOR BALANCING OF VIBRATIONS FORMED BY ENGINE, AND ROW FOUR-CYLINDER ENGINE CONTAINING SUCH SYSTEM Russian patent published in 2015 - IPC F16F15/26 

FIELD: engines and pumps.

SUBSTANCE: system (131) of masses of opposite rotation is intended to be used with a row four-cylinder internal combustion engine containing oil tray (134) and having sequence of operation of cylinders 1-3-4-2 (4.1, 4.3, 4.4, 4.2) for balancing of alternating forces of the second order, which are formed on the drive shaft of the engine. The system is arranged in the oil tray and includes central support (21) and two pairs of eccentric masses (22, 23, 24, 25) of opposite rotation, which project from two opposite sides of the supports, and two gear wheels (28, 29), each of which is arranged coaxially to the corresponding pair of eccentric masses of opposite rotation. Each gear wheel is arranged between two corresponding eccentric masses and remains on one side of the central support. Gear wheels are engaged with each other. One of the gear wheels has a possibility of bringing the corresponding gear of the drive shaft into rotation.

EFFECT: reducing dimensions of the system.
