Description

Сущность изобретени  касаетс  способов уравновешивани  сил и мо-менто в инерции первого и второго пор дков в двухтактных двенадцатицилиндровых двигател х внутреннего горени  с двум , вращающимис  в одну и ту же сторону, одинаковыми коленчатыми валами с расположенными под углом 60° друг другу коленами, дл  поршней двух параллельных р дов цилийдров .The invention relates to methods for balancing forces and torque in inertia of the first and second order in two-stroke twelve-cylinder internal combustion engines with two rotating in the same direction, the same crankshaft with the knees at 60 ° to each other for pistons two parallel rows of qilidons.

При предлагаемом способе оба коленчатых вала устанавливаютс  с относительным сдвигом фаз вращени  на 90°, чем достигаетс  уравновешивание сил и моментов инерции первого и второго пор дков.With the proposed method, both crankshafts are installed with a relative phase shift of 90 ° of rotation, thereby balancing the forces and moments of inertia of the first and second order.

На чертеже фиг. 1 изображает схему установки валов, фиг. 2 - схему моментов.In FIG. 1 shows the installation of shafts; FIG. 2 - the scheme of moments.

Два вала с коленами 1, 2, 3, 4, 5, 6 каждый дл  поршней одного из двух параллельных р дов цилиндров двенадцатИЦили«дрового двухтактного двигател  внутреннего горени  установлены параллельно, а колена расположены под углами 60° друг к .другу и в таком пор дке, при кото-ром моменты инерции первого пор дка полностью уравновешиваютс  (фиг. 1).Two shafts with elbows 1, 2, 3, 4, 5, 6 each for pistons of one of two parallel rows of cylinders of twelveIs or a wood two-stroke internal combustion engine are installed in parallel, and the elbows are located at angles of 60 ° to each other and then In this case, the first-order moments of inertia are completely balanced (Fig. 1).

Оба вала синхронно вращаютс  в одну и ту же сторону, причем один вал должен опережать другой с относительны .м сдвигом фаз вращени  на 90-.Both shafts rotate synchronously in the same direction, with one shaft leading the other with a relative phase shift of 90 degrees.

При этом двигатель будет полностью уравновешен включительно до сил и моментов инерции второго пор дка .In this case, the engine will be fully balanced, inclusively, up to second-order forces and moments of inertia.

В самом деле, величина момента второго пор дка поступательно движущихс  частей, св занных с любым коленчатым валом по Зассу может быть построена так, как показано на схеме фиг. 2.In fact, the magnitude of the moment of the second order of progressively moving parts associated with any crankshaft according to Zass can be constructed as shown in FIG. 2

Здесь О А - некоторый вектор, вращающийс  в плоскости вращени  любого кривошипа с удвоенной угловой скоростью вращени  коленчатого вала, ОВ - его проекци  на ось цилиндра, ОС - вектор ОВ, повернутый на 90° в сторону вращени  и представл ющий искомый момент М„ второго пор дка .Here, OA is some vector rotating in the plane of rotation of any crank with twice the angular speed of rotation of the crankshaft, OB is its projection on the cylinder axis, OS is the OB vector rotated by 90 ° in the direction of rotation and representing the desired moment M of the second time dca.

Дл  второго вала, опережающего первый на 90 , соответствующие век-торы будут О А , ОВ и ОС М ,.For the second shaft, ahead of the first by 90, the corresponding vectors will be OA, OB and OS M,.

Так как валы одинаковой конфигурации , то вектор ОА равн етс  ОА, Мц равн етс  М„.Since the shafts of the same configuration, the vector OA is equal to OA, Mz is equal to Mn.

Следовательно результирующий момент второго пор дка такого двухвального двигател  будет равен нулю и двигатель будет полностью уравновешен .Consequently, the resulting second-order moment of such a two-shaft engine will be zero and the engine will be completely balanced.

Предмет изобретени .The subject matter of the invention.

Способ уравновешивани  сил и моментов инерции первого и второго пор дков в двухтактных двендцатицйлиндровых двигател х внутреннего горени  с двум  вращающимис  в одну и ту же сторону одинаковыми коленчатыми валами с коленами, расположенными под углом 60 друг к другу, дл  порщней двух параллельных цилиндров, о т л и Ч а ю щ и и с   тем, что оба коленчатых вала устанавливают с относительным сдвигом фаз вращени  на 90°.The method of balancing the forces and moments of inertia of the first and second order in two-stroke two-twenty-cylinder internal combustion engines with two identical crankshafts rotating in the same direction with their knees at an angle of 60 to each other, for two parallel cylinders, and so that both crankshafts are installed with a relative phase shift of 90 °.
