Abstract

FIELD: two-cylinder and four-cylinder internal combustion engines; conversion of reciprocating motion of piston into rotary motion of shaft. SUBSTANCE: offered method provides conversion of reciprocating motion of piston directly into rotary motion of shaft of internal combustion engine without crank mechanism. In offered device piston of engine is connected with connecting rod-rack (in form of fork), with inner surfaces of cheeks on length corresponding to value of piston stroke being made in form of toothed rack-plate for engagement with gears-disks placed on shaft between two connecting rods-racks (fork). Number of gears-disks corresponds to number of engine cylinders. Diameter of gear-disk and length of circumference in gears-disks on which teeth are cut corresponds to engine cycle. For instance, at cycle equal to two revolutions of shaft, teeth are cut on half the length of gear-disk circumference, diameter of which corresponds to value of piston double stroke divided by 3.14 (π). EFFECT: enlarged operating capabilities, increased efficiency of transmission of torque, reduced cost and simplified design of engine, its overall dimensions and labour input at repairing.

Изобретение относится к двигателестроению, в частности к передаче возвратно-поступательного движения поршня во вращательное движение вала, и может быть применено в поршневых двигателях внутреннего сгорания как с двумя цилиндрами, так и с четырьмя цилиндрами. Применение предлагаемого способа и устройства повысит эффективность передачи крутящего момента, снизит стоимость двигателя и упростит его конструкцию, а также уменьшит его габариты и снизит трудоемкость его ремонта. Предлагаемый способ ведут путем преобразования возвратно-поступательного движения поршня непосредственно во вращательное движение вала, исключая тем самым осуществление промежуточной передачи возвратно-поступательного движения поршня через кривошипно-шатунный механизм валу двигателя внутреннего сгорания. В предлагаемом устройстве поршень двигателя соединен с шатуном-рейкой (в виде вилки), внутренние поверхности щек которых на длине, соответствующей величине хода поршня, выполнены в виде зубчатой рейки-пластины с возможностью их взаимодействия с шестернями-дисками, размещенными на валу между двумя шатунами-рейками (вилкой), причем количество шестерен-дисков соответствует числу цилиндров двигателя. Кроме того, диаметр шестерни-диска и величина длины окружности в шестернях-дисках, которая снабжена зубьями, соответствует циклу двигателя. Например, при цикле двигателя, равном 2-м оборотам вала, зубья размещены на половине длины окружности шестерни-диска, диаметр которой соответствует величине двойного хода поршня, деленной на пи (3,14).The invention relates to engine building, in particular to the transfer of reciprocating motion of a piston into rotational motion of a shaft, and can be applied in reciprocating internal combustion engines with both two cylinders and four cylinders. The application of the proposed method and device will increase the efficiency of torque transmission, reduce the cost of the engine and simplify its design, as well as reduce its dimensions and reduce the complexity of its repair. The proposed method is carried out by converting the reciprocating motion of the piston directly into the rotational movement of the shaft, thereby excluding the implementation of the intermediate transmission of the reciprocating motion of the piston through the crank mechanism to the shaft of the internal combustion engine. In the proposed device, the engine piston is connected to the connecting rod (in the form of a fork), the inner surfaces of the cheeks of which are made in the form of a gear rack-plate with a length corresponding to the size of the piston stroke, with the possibility of their interaction with the gear disks placed on the shaft between the two connecting rods -rails (fork), and the number of gears-disks corresponds to the number of engine cylinders. In addition, the diameter of the gear disk and the circumference of the gear wheels, which is equipped with teeth, corresponds to the cycle of the engine. For example, with an engine cycle equal to 2 shaft revolutions, the teeth are placed at half the circumference of the gear-disk, the diameter of which corresponds to the double piston stroke divided by pi (3.14).
