Description

The invention relates to mechanical engineering and can be used in drives of various machines and mechanisms as a reduction gear "is an improvement of the invention according to the authors. St. No. 1557396.

The purpose of the additional invention is to improve the smoothness and the elimination of shocks when reversing the work of a roller transmission.

FIG. 1 shows the transmission, in section; in fig. 2 is a section A-A in FIG. one.

The planetary gear (Fig. 1) contains a driving link mounted on the eccentric 1, formed by coaxial rings 2 and 3, mounted on the driven shaft disk 4 with a closed periodic groove, located on both sides of the driving link two disks 5 and 6 with radial slots mi drove separator rollers 7, placed

with their ends in the slots of the carrier-separator and the periodic groove, additional disks 8 and 9, also with radial slots, mounted rotatably with respect to disks 5 and 6 and associated with these disks by conical pins 10, spring-loaded springs 11.

The pins 10 (FIG. 2) are placed in the conical holes of the main disk b and the additional disk 8, as well as in the holes of the disks 5 and 9. The holes in the pairs of disks are displaced axially relative to each other, i.e. with combined radial slots, they are not coaxial. Initial misalignment Determined by the size of the conical pins.

Planetary gear works as follows.

When the drive shaft and the eccentric 1 rotate, the rollers 7 receive a reciprocating motion along the slots of the disks 5,

6 and additional disks 8 and 9. In this case, the rollers 7 with their ends act on the closed periodic groove of the disk 4 and thereby cause the rotation of this disk, and with it the rotation of the driven shaft.

Making a reciprocating motion along the slots of the disks 6, 8 and 5, 9. The rollers 7 cause the L and M surfaces of these slots to wear out. The gaps that appear in this case are automatically selected when axially displaced by the action of the springs 11 of the conical pins 10. With this movement of the pins 10 (Fig. 2), the initial misalignment of the holes A in the disks 6 and 8 decreases, and the surfaces M of the radial slots in these disks move towards each other, choose gaps. The impact of the rollers 7 on the surfaces L and M of the slits does not cause a disclosure of the selected

gaps, as the conical pins are self-braking. The spring 11 in the roller transfer should not create significant pressure surfaces L and M of the slots of the disks on the roller 7.
