The invention relates to the field of engineering, and in particular to mechanisms for converting rotary motion with constant frequency in the rotation with variable speed of rotation of the driven link and can be used in various fields of technology.A known mechanism for converting rotary motion into reciprocating containing the crank, the drive its rotation, CoroMill is echanism is its limited technological capabilities, as it does not provide movement of the rocker arm for moving trajectory.Also known mechanism for converting rotary motion into reciprocating containing the crank, the drive its rotation with the pulley arm and the connecting rod, one end of which is pivotally connected with the rocker, and the other with the crank mechanism provided with a gear rigidly connected with the crank, and mounted on the body and cooperating with the pinion gear and the crank gear is installed in the pulley rotation of the crank 
The closest in technical essence to the invention is a mechanism for converting rotational motion into rotational variable frequency, comprising a housing with fixed therein a wheel with internal teeth, mounted in the housing for rotation concentric with the wheel with internal teeth pulley with two symmetrically-eccentric holes that are installed in these holes with the possibility of rotation of the crank shafts mounted on one end of the cranks, and the other gear wheel with external teeth that is meant to interact with the wheel with internal teeth mounted in the housing concentric with each other is ncom with the corresponding crank, and the other with the corresponding rocker, driven clutch, the faceplate and the differential, one link of which is connected to the faceplate, the second main beam, and the third through controlled clutch with optional rocker 
A common drawback of all the above mechanisms is the low value of the transmitted torque.The objective of the invention increase the magnitude of the transmitted torque.For this mechanism converting rotational motion into rotational variable frequency, comprising a housing fastened in it the wheel with internal teeth, coaxial him and installed in the housing to rotate the pulley with two holes arranged symmetrically on a circle, the center of which is eccentric relative to the axis of the pulley installed in these holes, the shaft carrying at one end a gear wheel gear wheel with internal teeth, on the other yokes, yoke, axle bearings which are aligned with the axis of the pulley, the two connecting rod pivotally connected each at one end with a yoke, the other with the corresponding crank, and the face-plate, the rocker made two shoulders with equal and symmetrical with respect to the axis of the rocker shoulders, Enviroline mechanism allows for up to half of the magnitude of transmitted torque.The drawing shows the mechanism, General view.The mechanism includes a housing 1 mounted on bearings 2 pulley 3 actuator (not shown) of rotation of the cranks 4 and 5 are accommodated in the housing 1 gear wheel 6 with the internal teeth are fixedly mounted on the cranks 4 and 5 gears 7 and 8 with external teeth that are designed to interact with the toothed wheel 6 with the internal teeth mounted in the housing 1 in the bearings 9 and 10, the rocker arm 11, the connecting rods 12 and 13 with one end pivotally connected with the respective fingers 14 and 15 of the cranks 4 and 5, and the other, also articulated with the corresponding fingers 16 and 17 of the rocker arm 11, arranged symmetrically and opposite to one another, and the faceplate 18 fixed to the arm 11.The cranks 4 and 5 mounted on bearings in symmetric and eccentric made the holes in the pulley 3.The fingers 14 and 15 of the cranks 4 and 5 are located opposite one another.The mechanism works as follows.Rotation of the pulley 3 drives the cranks 4 and 5 due to the interaction of the wheels 7 and 8 with the wheel 6. These movements through the connecting rods 12 and 13 are transmitted to the rocker arm 11, which causes the rotation of the variable frequency of the faceplate 18. The rocker 11 vigani rotation of the rocker arm 11 around its axis occurs with variable frequency. The magnitude of the oscillations of the rocker arm 11 is dependent upon the length of the cranks 4 and 5, connecting rods 12 and 13 and the rocker arm 11, and the frequency of gear ratio of the gears 7, 8 and the gear wheel 6.In the case of using the mechanism for lapping on the faceplate 18 strengthen the abrasion element, such as a valve, which makes a relatively stationary valve seat, the reciprocating movement on the moving path.Transforming rotary motion into reciprocating along the moving trajectory of the mechanism is accomplished by moving the axes of rotation of the cranks 4 and 5.Torque in the mechanism creates both cranks 4 and 5, each of which acts on a corresponding shoulder of the rocker arm, thus a pair of forces, which increases the module torque in two times in comparison with the mechanism of the prototype. The mechanism for converting rotational motion into rotational variable frequency, comprising a housing fastened in it the wheel with internal teeth, coaxial him and installed in the housing to rotate the pulley with the two holes located on a circle, the center of which is eccentric relative the of wheel with internal teeth, on the other cranks, rocker, swing axis which is aligned with the axis of the pulley, the two connecting rod pivotally connected each at one end with a yoke, the other with the respective crank, and the faceplate, wherein the rocker is made with two shoulders equal and symmetrical with respect to the axis of the rocker shoulders, pivotally connected to the respective rods, the axes of which lie in one plane.

SUBSTANCE: invention relates to machine building. Rotation from drive shaft is transferred via differential gearbox rotating around its axis, and dividing engine energy to two outputs. One part via the first output enters directly the driven shaft, and from the second output to device able to slip transferring rotation also to the driven shaft bypassing gearbox.
