Description

In the proposed cut-off, a rotating metal segment (provided with two spiral; and one circular grooves forming a common groove for the rollers that are attached to two separate conversion rails from the two forks is used to transfer the drive belts. The segment is rotated with a cord , - enclosing the block constituting one unit with the segment.

In the schematic drawing of FIG. 1 shows a general view of the location of the working and idler pulleys with the leads; and FIG. 2-view of the slips from the end.

The branch has the form of a segment A (Fig. 2) with two spiral grooves a and cf and one circular groove b, which include 3 TK JK rollers attached to two separate conversion rails or leads for forks g n g. Segment A is tightly fastened to segment A, covered by cord n - p. The mutual arrangement of i and x pulleys, working pulley g and leads with forks g and g and lin to their movement is shown in FIG. one.

- When the cord is tensioned, the roller з will move to the right to the position з, while the roller, being in a circular groove, remains stationary, and the belt from the idle pulley x will be shifted to the working pulley. Similarly, the roller When tensioning the cord is used to transfer the belt from pulley x. on the working pulley g with a preliminary shift from the last belt to the pulley x. To prevent the self-translation of the belts, the cuts in the wall of the chute are used to stop the rollers of the bfs. To be able to change the direction of rotation, one of the belts, for example, is put on the pulleys directly and the other, for example, X, is crossed.

The subject matter of the invention.

A drive belt suspension characterized by using a rotating segment A equipped with two spiral points a and a and a circular groove o forming a common groove for rollers 3 and 2 connected to two separate decal rails or drivers for two forks g and g.
