The invention relates to mechanical engineering, in particular, to devices, the output links of which contain continuous, rotation, and can be used in the food, chemical, machine-tool industry and other parts of mechanical engineering.

The purpose of the invention is to increase reliability by eliminating drive overheating,

The initial position is taken when the axes of the shoulder 16 of the two arms and the connecting rod 18 approximately coincide and the levers occupy a position close to unstable equilibrium, the stop 14 of the actuating lever 5 presses on the elastic element 2 and squeezes it as much as possible.

To start the movement, the electromagnet 11 engages the drive pin 7 into engagement with the hole 10 of the separating disk 9. The drive 4 spins on the output shaft 1 the spiral clockwork

with safety switch in two positions On-15 off. The intermittent rotation device contains an output shaft 1, a mechanical energy battery, made in the form of two elastic elements 2 and 3, a drive 4, an actuator, including two driving levers 5.6 mounted on the shaft 1 with driving fingers 7 and 8 dp of interaction with a separating disk 9 with holes 10 fixed on the output shaft 1. The driving fingers 7 and 8 are controlled by electromagnets P. and 12. The driving levers 5 and 6 are double-shouldered with stops 13 and 14, designed to interact with an elastic element. Actors 2. and 3. In addition, the mechanism of fixation, includes two shoulders rocker with shoulders ,,. 15 and 16, pivotally connected with the driving levers 5 and 6 by connecting rods 17 and 18. The swing angle of the two-arm with arms 13 and 6 is limited to ynopai iH 19 and 20. From the position of two arms and arms 15 and 16 outputted by electromagnets 2} and 22.

The actuator 4 is connected with a worm 23, which drives the wheel 24, on which one end of the spiral winding crown 25 is attached. The other end is fixed to the output shaft 1.

It ejects and pushes the shoulder 16 of the double-arm rocker from the state of height and the system moves out of a position close to unstable equilibrium. The elastic element 2, expanding, accelerates through the stop 14 the drive lever 6, and with it the output shaft 1.

The potential energy of the elastic element 2 is transformed into the kinetic energy of the moving parts of the device. This happens until the elastic element 2 is completely dissolved. In this case, the drive lever 6 rotates in the opposite direction of rotation of the drive lever 5. The stop 13 reaches the elastic element 3 and begins to compress it. The deceleration begins, at which the kinetic energy of the mobile units of the transfer device. goes to the potential energy of the compressed spring 3. When the arm reaches the rocker arm 15 of the stop 19, the system stops and takes a position close to unstable equilibrium. With water 4, the spring 25 continues to twist. When the required twisting is increased, clutch 26 begins to slip and the drive 4 does not overload.

 The force of the winding coil spring 25 is designed so that in one cycle of motion it compensates for friction losses in the system. During high speed, an electromagnet 12 inserts a drive pin 8 into the hole 10, and a nitrile 11 pulls the pin 7 out of engagement with the dividing disc 9.

In order to avoid overloading the actuator 4, a mechanism is provided, made, for example, in the form of a safety clutch 26, which regulates the twisting force of the winding coil spring 25. For this purpose, a safety switch 27 can be used (FIG. 3 and 4).

The device works in the following way.

It ejects and pushes the shoulder 16 of the two shoulders of the rocker from the state of height and the system moves out of a position close to unstable equilibrium. The elastic element 2, expanding, accelerates through the stop 14 the drive lever 6, and with it the output shaft 1.

The potential energy of the elastic element 2 is converted into the kinetic energy of the moving parts of the device. This happens until the elastic element 2 is completely unclenched. In this case, the drive lever 6 rotates in the opposite direction of rotation of the drive lever 5. The stop 13 reaches the elastic element 3 and begins to compress it. The braking begins, at which the kinetic energy of the moving links of the transfer device. goes to the potential energy of the compressed spring 3. When the arm reaches the rocker arm 15 of the stop 19, the system stops and takes a position close to unstable equilibrium. The actuator 4 continues to twist the spring 25. With an increase in the required twisting force, the clutch 26 begins to slip and the actuator 4 does not overload.

 The force of the winding coil spring 25 is designed so that in one cycle of movement it compensates for friction losses in the system. During high speed, an electromagnet 12 inserts a driving pin 8 into the hole 10, and the electromagnet 11 removes the pin 7 from engagement with the dividing disc 9.

Upon completion, the electromagnet 22 outputs the system from an unstable equilibrium position, and the next 1st cycle of motion begins, which proceeds in a similar way.
