SU70506A1 - Transmission with infinitely variable transmission ratios - Google Patents

Description

Gears with a stepless change in the gear ratio, which enclose a ring with a set of plates that are freely seated in a cage, which engage with two sour-cone cones, are known. This ring, together with the yoke, moves in its plane to change the radius of engagement with the cones.

A distinctive feature of the proposed transmission is that both cones are mounted on the drive shaft and are connected to the last sliding key connection, and the ring is equipped with a gear ring which is in engagement with the gear wheel of the driven shaft, which also carries a swinging clip on it.

For axial movement of the gear cones coaxially with the yoke, the gear sectors associated with it are mounted on the driven shaft. The latter rotate the nuts, which are sitting coaxially with the drive shaft, and move the toothed cones.

FIG. 1 is a schematic diagram of the proposed transmission; yes figs. 2 is a section through ABC of FIG. one.

22 Body in. 2,

On the drive shaft 7, two toothed cones 2 (FIG. 2) are engaged on the keys and engage with ring 3 by means of plates 7 arranged on the inner surface of the ring of ring 7. Ring J carries gear 4, which engages gear 5 of the driven shaft 6. From turning inside the ring 3, the plates 7 are held by the protrusions 8, and from displacing them to the center of the ring - by an expanding sliding ring 9.

Between the cones 2, a spring Yu is placed, pressing them against the thrust bearings 77. Gear nuts 14 coaxially with the driving shaft 7 are installed, which are in engagement with the teeth 75, which sit in bearings 76 on the driven shaft 6. The sectors 75 rotate gear nuts 74 which axially move the gear cones 2.

The rotation is transmitted from the drive shaft 7 through the cone 2, the ring 3 and the gear ring 4 to the gear 5 of the driven shaft 6.
