Abstract

FIELD: mechanical engineering. SUBSTANCE: piston machine has cylinders, pistons, and crankshafts mounted inside the housing. The shafts are provided with gear wheels. The number of cylinders, pistons, crankshafts, gear wheels is a multiple of 2. Each piston is provided with a rod coupled with cranks of the crankshafts through a pair of connecting rods. One of the connecting rods is coupled with the first crankshaft. The other connecting rod is coupled with the second crankshaft. The gear wheels of the crankshafts are in engagement. The machine mechanism (pistons, rods, connecting rods, crankshafts, and gear wheels being assembled) is symmetrical with respect to the plane perpendicular to the plane, wherein the axes of the engaged gear wheels are arranged, and passing through the point of contact of the dividing circumferences of the wheels. The total displacement of all pistons in any time interval is zero. EFFECT: improved design.

Для создания поршневой машины с идеальной статической и динамической уравновешенностью при доступной технологии изготовления и приемлемой стоимости, поршневая машина содержит установленные в корпусе цилиндры, поршни и коленчатые валы, снабженные находящимися во внешнем зацеплении зубчатыми колесами. При этом по количеству цилиндры, поршни, коленчатые, зубчатые колеса кратны двум, а каждый поршень снабжен штоком, соединенным с кривошипами коленчатых валов парой шатунов, один из которых соединен с первым коленчатым валом, а другой - со вторым, зубчатые колеса которых находятся в зацеплении. Механизм машины (поршни, штоки, шатуны, коленчатые валы и зубчатые колеса в сборе) выполнен симметричным относительно плоскости, перпендикулярной к плоскости, в которой размещены оси находящихся в зацеплении зубчатых колес, и проходящей через точку касания делительных окружностей этих колес, при этом геометрическая сумма перемещений всех поршней за любой промежуток времени равна нулю.To create a piston machine with perfect static and dynamic balance with affordable manufacturing technology and reasonable cost, the piston machine contains cylinders, pistons and crankshafts installed in the housing, equipped with gears located in the external gearing. In this case, the number of cylinders, pistons, crankshafts, gears is a multiple of two, and each piston is equipped with a rod connected to the crankshafts of the crankshafts with a pair of connecting rods, one of which is connected to the first crankshaft, and the other to the second, whose gears are engaged . The mechanism of the machine (pistons, rods, connecting rods, crankshafts and gears assembly) is made symmetrical with respect to a plane perpendicular to the plane in which the axes of the engaged gears are placed and passing through the tangent point of the pitch circles of these wheels, while the geometric sum displacements of all pistons for any period of time is zero.
