Description

one

The invention relates to mechanical engineering, can be used to change the speed of rotation of the working organs of machines, and is an improvement of the known device. St. No. 1260622.

The purpose of the invention is to increase reliability by supplying the gearbox with additional friction pits. kami.

Figure 1 schematically shows the gearbox, a general view; FIG. 2 is a section A-A in FIG. 1;

The impulse gearbox includes a housing 1, in which a driving shaft 2 with eccentrics 3, a driven shaft 4 with a flywheel 5 and earrings 6, a rocker arm 7, made in the form of two-armed L-shaped levers, which are hingedly connected to the earrings 6 and eccentrics, are installed on it. 3, the clamping elements in the form of friction blocks 8, placed on the short arms of the rocker arms 7 and interacting with the flywheel 5; In the earrings 6, grooves 9 can be made, with which they can be displaced in a direction perpendicular to the axis of the driven shaft 4, placed on the dry p x 10, mounted on the driven shaft 4; On the earrings 6, additional friction pads 11 are also attached, which interact with the flywheel 5 on the diametrically opposite side relative to the main friction rings Doc 8, B of the housing 1 also has a stop 1 for moving gray g 6. Rocker arm 7 associated with housing 1 by means of springs 13,

The gearbox works as follows.

 During rotation of the drive shaft 2 of the rocker arm 7, pivotally connected to the eccentrics 3, alternately make oscillatory movements. When the rocker arm 7 deviates from the drive shaft 2

its working stroke is made, when the co-, tsrom under the action of the spring 13, the crown 7, turns toward the earring b, presses the pad 8 to the flywheel 5 and causes it to rotate. At the same time, the earring is 6

7 is displaced along the cracker 10 to the right, pressing the block 11 against the flywheel 5 against the Q in the opposite block 8 of the side. Both pads clamp the flywheel 5 with a force that is proportional to the moment on the flywheel and turn it at an angle corresponding to the movement of the rocker arm 7. At the moment when one of the rocker arms 7 makes a working stroke, the other rocker idle. At the same time the yoke 7 with an earring 6 and pads

8 and 11 return to their original position under the influence of the spring 13, the shoes 8 and 11 are thus easily slid over the surface of the flywheel 5. It is possible that the shoe 11 sticks to the surface of the flywheel. With this earring

2g 6 rotates fully against the stop 12 and detaches from the flywheel 5.

Pulse gearbox can provide an unlimited number of transmissions - 2Q number. The direction of rotation of the driven shaft 4 is independent of the direction of rotation of the driving shaft 2,
