Description

Pulsed planetary gears with the direction of rotation of the driven shaft corresponding to the direction of rotation of the drive shaft are known — with a coaxial arrangement of the input and output shafts consisting of a planetary gear, carrier rigidly connected with the driven shaft, and connected to the carrier of satellites on eccentric trunnions which are placed ratchet. The ratchet is pressed against the inner surface of the ring gear by springs.

The described gearbox is different from the known ones in that the ratchets are double-sided, automatically switched depending on the direction of rotation of the drive shaft.

This makes it possible to rotate the driven shaft to either side depending on the rotation of the drive shaft.

For automatic switching of the hripovik, the gearbox is equipped with two shoulders levers, pressed against the ends of the rotating satellites and actuated by the resulting friction forces.

The drawing shows the gearbox described in two projections.

The ratchets 7 are double-sided, so that when the tips 2 of the ratchets through the roller 5 are in engagement with the ring crown 4 on the one hand, on the other hand the identical parts of the ratchets are not linked to it.

The constant pressing of the ratchet to the inner surface of the ring gear 4 is mounted with one shoulder of the two shoulders lever 5. The other shoulder with its spring 6 is pressed against the end surface of the satellite 7. To eliminate the force along the axis of the satellites, the corresponding arms of two levers 5 are pressed against them. side, counterclockwise, satellite, lying, and sj clockwise due to the force of treNo 151538-2 -

nor, carries the shoulders of two shoulders levers 5 pressed to it from both sides, and the other shoulders of these levers press one side of the ratchet /, sitting on the axis of the same satellite, to the inner surface of the gear ring 4- In this case, the driven shaft will receive an anti-clockwise rotation .

When the rotation of the lead vada changes to the opposite one, the satellite will also change the direction of rotation and drag the shoulders of the Druple arms to the other side. This will lead to the fact that the other shoulder of the two shoulders lever will also change its position and will press the other side of the ratchet to the inner surface of the gear teeth. At the same time, the driven shaft will begin to rotate clockwise.

Subject invention

1. A pulsed planetary gearbox with direction of rotation of the driven shaft in accordance with the direction of rotation of the drive shaft, with coaxial arrangement of the input and output shafts, consisting of a planetary gear, drove rigidly connected with the driven shaft and connected to the carrier satellites, on which eccentric axles are placed ratchets, characterized in that, in order to be able to rotate the driven shaft in any direction, depending on the rotation of the drive shaft, the ratchets are double-sided, automatically reklyuchaemymi depending on the direction of rotation of the drive shaft.

, 2. The gearbox according to claim 1, characterized in that, in order to automatically switch the ratchet, it is equipped with double-arm levers, pressing the springs to the ends of the rotating satellites and p) and actuated by the resulting friction forces.
