Abstract

This invention relates to mechanical engineering, namely gearing. The purpose of the invention is to simplify the design of the mechanism by changing the phasing of the weights. When the motor shaft 16 rotates, the drive units 5 and 6 of the planetary pulsators 1 and 2 will rotate in different directions and due to the fact that their unbalanced satellites 11 and 12 are set in antiphase, and the driven members 7 and 8 are rigidly connected to each other, the torque pulses on the latter will be summed, and the pulses on the leading links x 5 and 6 will be damped by the housing 4, unloading the shaft 1 b of the engine. 1 il.

about

The invention relates to mechanical engineering and can be used in test benches, inertial torque transformers, machine tools for vibro-spindle machining of parts, etc.

The purpose of the invention is to simplify the design of the mechanism,

The drawing shows the proposed pulse mechanism.

The impulse mechanism contains two planetary pulsers 1 and 2, a planetary gear 3 and a housing 4. Each planetary pulser 1 and 2 consists of leading 5 and 6 and slave 7 and 8 links, between which satellites 11 and 12 are unbalanced by means of loads 9 and 10. The planetary gear 3 is made in the form of a differential mechanism, the central wheels 13 and 14 of which are connected respectively to the leading links 5 and 6 of the planetary pulsators 1 and 2. The satellite 15 of the planetary gear 3 is connected to the motor shaft 16, and the carrier 17 is fixed with respect to the housing 4; In this case, the driven members 7 and 8 of the planetary impulseors 1 and 2 are rigidly interconnected by the shaft 18, and the unbalanced with weights 9 and 10, the satellites 11 and 12 are installed in antiphase. The gears of the planetary pulsators 1 and 2 can be made helical, and the driven members 7 and 8 can be axially moved.

The impulse mechanism operates cyclically as follows.

With apauieHWH of the engine shaft 16, the drive members 5 and 6 of the planetary pulsators 1 and 2 rotate in different directions, and the satellites 11 and 12, rotating about their axes, roll around the driven members 7 and 8 connected by a shaft 18. At the same time The driven members 7 and 8 of the planetary impulseors 1 and 2 are impulses of alternating torque, the change of which is sinusoidal. When the load 9 unbalanced satellite 11 from the upper position to the lower on the slave link 7 of the planetary pulser 1 acts a positive impulse (the direction of which coincides with the direction of rotation of the driving link 5 clockwise from the center wheel 13), the torque moment acting on the driving link 5, the planetary pulser 1 clockwise (from the side of the central wheel 13) is transmitted to the central wheel 13 and the satellite 15, and from there to the shaft 16 of the engine. At the same time, when moving goz 10 unbalanced satellite 12

From the lower position to the upper, the follower link 8 of the planetary pulser 2 is acted upon by a negative impulse (the direction of which is opposite to the direction of rotation of the driving link b of the planetary pulser 2, which rotates clockwise from the side of the central wheel 14). Torque pulse acting on the leading link 6

0 of the planetary pulser 2, is counterclockwise (from the side of the central wheel 14) and transmitted to the central wheel 14 and the satellite 15, and from it to the engine shaft 16. With this direction

the effect of the negative pulse on the driven link 8 coincides with the direction of the positive pulse on the driven link 7. Therefore, the considered pulses add up and accelerate the driven

0 elements 7 and 8 in the direction of rotation of the driving member 5. A negative torque pulse acting on the driving link b coincides with the direction of the positive pulse on the driving link 5 and is transmitted to the central wheel 14 and satellite 15, and from it to the shaft 16 engine In this case, the direction of the pulses acting on the satellite 15 is the same, since the pulses of the torque,

0 acting from the leading elements 5 and 6 on the satellite 15, coincide in direction and attached to the diametrically opposite teeth of satellite 15, the engine shaft 16 is unloaded from the action

5 pulsed torque from the planetary impulse 1 and 2.

In the subsequent period of operation, the planetary pulsers 1 and 2 will operate in opposite phases and the pulses on the driving links x 7 and 8 will again be summed up, the acceleration of the driven members 7 and 8 and, therefore, the shaft 18 against the direction of rotation of the driving link 5 (in the direction of rotation of the driving link 6). And the pulses on the leading links x 5 and 6 will again be extinguished by the housing 4, unloading the motor shaft 16 from the action of pulsed loads in the circumferential direction.

Consequently, the installation of non-equilibrium satellite satellites of planetary pulsators in antiphase allows one to achieve the same effect while eliminating a number of intermediate nodes of the pulsed mechanism, which simplifies its design.
