Description

Как известно, уравновешенность  вл етс  основным требованием, предъ вл емым к двигателю внутреннего сгорани .As is known, equilibrium is a basic requirement for an internal combustion engine.

Предлагаемый способ уравновешивани  двухтактных двигателей внутреннего сгорани  заключаетс  в том, что с целью уравновешивани  моментов второго пор дка в каждом р ду цилиндров вал составлен из одинаковых групп, состо щих из нечетного числа колен, причем колена одной группы повернуты на 90° относительно колен другой группы.The proposed method of balancing two-stroke internal combustion engines consists in the fact that in order to balance second-order moments in each cylinder row, the shaft is composed of identical groups consisting of an odd number of knees, with the knees of one group rotated 90 ° relative to the knees of the other group.

На чертеже в качестве примера изображена схема расположени  групп колен с трем  коленами в каждой.In the drawing, as an example, a diagram of the arrangement of groups of knees with three knees in each is shown.

Рассматрива  пор док колен, обозначенный на чертеже цифрами 7, 2, 3, 4, 5 и 6, можно заметить, что данный вал состоит из двух совершенно одинаковых групп колен 7, 2, 3 и 4, 5, 6, как бы двух одинаковых трехколенчатых валов с углами между коленами в 120° на каждом валу, взаимно повернутых на 90°.Considering the order of the knees, indicated in the drawing by the numbers 7, 2, 3, 4, 5 and 6, it can be noted that this shaft consists of two completely identical groups of knees 7, 2, 3 and 4, 5, 6, as if two identical three-shafted shafts with angles between bends of 120 ° on each shaft, mutually rotated through 90 °.

В пределах каждого такого трехколенчатого вала полностью уравновешиваютс  центробежные и инерционные силы первого и второго пор дков трех сто щих в одном р ду цилиндров. Моменты же этих сил остаютс  неуравновешенными. Однако , так как два трехколенчатых вала, составл ющих шестиколенчатый , повернуты взаимно на 90°, то моменты второго пор дка таких валов будут равны и взаимно противоположны , так что в пределах каждого шестицилиндрового р да суммарные моменты второго пор дка будут равны нулю как при центральных, так и при прицепных шатунах.Within each such three-shaft shaft, the centrifugal and inertial forces of the first and second order of three cylinders standing in the same row are completely balanced. The moments of these forces remain unbalanced. However, since the two three-shaft shafts constituting the six-crankshaft are rotated mutually by 90 °, the second-order moments of such shafts will be equal and mutually opposite, so that within each six-cylinder row the total second-order moments will be zero as in the central , and when trailed rods.

При соблюдении указанного способа уравновешени  коленчатого вала импульсы от вспышек на коренном валу будут чередоватьс  через равные промежутки времени и совпадени  вспышек в двух цилиндрах не произойдет.If this method of balancing the crankshaft is observed, the pulses from the flashes on the main shaft will alternate at regular intervals and there will be no coincidence of flashes in the two cylinders.

при равномерном чередовании вспышек , отличающийс  тем, что с целью уравновешивани  моментов второго пор дка в каждом р ду цилиндров вал составлен из двух одинаковых групп колен с нечетным числом последних в каждой группе, причем колена одной группы повернуты на 90° относительно колен другой группы.with a uniform alternation of flashes, characterized in that in order to balance the second order moments in each cylinder row, the shaft is composed of two identical groups of knees with an odd number of the latter in each group, with the knees of one group rotated 90 ° relative to the knees of the other group.
