Шатуны 5 и 6 имеют параллельные оси шарниров и длину , равную двум длинам , т.е. 16-, . Все шарнирные соединения выполнены либо на подшипниках качения, либо на подшипниках скольжения. Смеситель может быть выполнен так, что ведущие кривошипы жестко закреплены на выходном валу редуктора 15. Редуктор 15 через муфту 16 связан с электродвигателем 2.The leading 3rd follower 4 cranks have the same parameters; d- - angle 35 when the cranks are hinged along the hinges, £ is the shortest distance between them (B is the length of the cranks). The angle i can be in the range of 10-4 2 °. The cranks 12 and 11 have an angle of intersection of the hinge axes equal to 180 ° - cL, and a length of 8 equal. the length of the cranks' .’3 and 4. The connecting rods 5 and 6 have parallel hinge axes and a length equal to two lengths, i.e. 16-, . All swivel joints are made either on rolling bearings or on plain bearings. The mixer can be made so that the leading cranks are rigidly fixed to the output shaft of the gearbox 15. The gearbox 15 is connected via a coupling 16 to the motor 2.

Смеситель работает следующим образом.The mixer operates as follows.

От привода 2 вращение передается общему валу 14 и жестко связанным с ним кривошипам 3 и 12. Кривошипы передают движение на шатуны 5 и 6, ведомые кривошипы 4 и 11 и на балансиры 8 и 13.From the drive 2, the rotation is transmitted to the common shaft 14 and the cranks 3 and 12 rigidly connected to it. The cranks transmit the movement to the connecting rods 5 and 6, the driven cranks 4 and 11 and to the balancers 8 and 13.

Барабаны 1 и 9, закрепленные на пальцах ведомых кривошипов Ц и 4, получают сложное пространственное движение, а именно вращение вокруг собственной продольной оси и возвратноВрашатепьно-качательное движение относительно оси качания балансиров 8 и 13. Балансиры .8 и 13 качаются в одной плоскости навстречу друг другу. Вращение балансиров 8 и 13 и шарнирно соединенных с ними ведомых кривошипов 4 и 11 с барабанами 1 и 9 обеспечивает полное взаимное уравновешивание моментов, возникающих от их неравномерного качательноГо движения, поскольку моменты равны по величине, но противоположны по знаку. За счет уравновешивания моментов снижается нагрузка на звенья привода, Можно увеличивать до потребной частоты вращения и колебание барабанов, а следовательно, интенсифицировать процесс смешения и производительность.Drums 1 and 9, mounted on the fingers of the driven cranks C and 4, receive complex spatial motion, namely, rotation around their own longitudinal axis and reciprocating movement relative to the swing axis of the balancers 8 and 13. Balancers .8 and 13 swing in the same plane towards each other to a friend. The rotation of the balancers 8 and 13 and the driven cranks 4 and 11 pivotally connected to them with the drums 1 and 9 provides a complete mutual balancing of the moments arising from their uneven rocking motion, since the moments are equal in magnitude but opposite in sign. By balancing the moments, the load on the drive links is reduced. It is possible to increase the rotation speed and vibration of the drums to the required speed, and therefore, to intensify the mixing process and productivity.

В случае выполнения смесителя с жестким креплением ведущих кривошипов на выходном валу редуктора 15 вращение от электродвигателя 2 через муфту 16 передается выходному валу и редуктору 15 вместе с жестко закрепленными на нем кривошипами 3 и 12, Далее устройство работает аналогичным образом. ^гПредлагаемое выполнение смесителя ' позволяет'значительно интенсифицировать процесс смешения за счет увеличения частоты вращения и качения барабане» и повысить производительность.In the case of a mixer with a rigid fastening of the leading cranks on the output shaft of the gearbox 15, rotation from the electric motor 2 through the clutch 16 is transmitted to the output shaft and gearbox 15 together with the cranks 3 and 12 that are rigidly fixed on it. Further, the device works in a similar way. ^{g The} proposed embodiment of the mixer “allows” to significantly intensify the mixing process by increasing the frequency of rotation and rolling of the drum ”and to increase productivity.
