The invention relates to mechanical engineering, in particular, to conic non-voluntary transmissions.

The aim of the invention is to expand the kinematic transmission capabilities by changing its center-to-center distance.

FIG. 1 shows a gear; in fig. 2 is a section A-A in FIG. one.

A gear transmission includes a housing 1, two non-invasive conical wheels 2 3: which are mounted at the vertices of the cones; Meeting one another on parallel shafts 4 and 5. The wheel 2 is rigidly mounted on the shaft 4, and wheel 3 has an axial OPTIMIZATION displacements relative to shaft 5. In case 1, the following guides are made 6,) m () linear bows 1, 1; x relative to the axes of -1 -1 and il:; о ;: i:; 0, i, equal to the angle dividing the;) forest - and 5, grooves 7 and the threaded hole 8, in which is located. U 13 13,;, 6, located rief) io; i; uii y-, iHpuo shafts 4 and 5, installed An axle 10, in which a shaft of 5 m 5 is located. 9. On the stunit of wheel 3, carriage 12 is mounted on supports 1 of rotation with rollers 13 located on the same axis O-O. Rollers 13 are intended to interact with grooves 7 of housing 1.

Gear transmission works as follows.

Transmission from wheel 2 to wheel 3 and vice versa occurs as a result of the engagement of the working surfaces of the teeth. If it is necessary to change the axial distance, rotate the screw 9 in the threaded hole 8 of the housing 1 and thereby move the frame 0 together with the shaft 5, the movable wheel 3 and the carriage 12 perpendicular to the axis of the wheels 4 and 5 along the guides 6. In this case, the rollers 13 interact with grooves 7. Since the grooves 7 are at an angle to the axles of wheels 2 and 3, equal to the angle of their separating cones,

the movable wheel 3 moves along the pitch of the direct toothed wheel x 2 and 3. The radial Y and X components of the movement of the wheel 3 are interconnected by the dependence

Y X-tg {,

where b is the angle dividing cones of gear wheels 2 and 3 and, accordingly, the angle of slots 7.

Thus, the radial displacement of the shaft 5 together with the axially movable wheel 3 provides for a change in the distance between the axles, and the displacement of the wheel 3 along the axis of the shaft 5 automatically preserves the constant lateral clearance in the engagement.
