Description

The invention relates to mechanical engineering and can be used as a drive for machines and mechanisms.

The purpose of the invention is to improve the accuracy of transmission.

FIG. 1 shows the transmission, longitudinal section} in FIG. 2 shows section A-A in FIG. one.

The transmission includes a housing 1, gears 2 and 3, the pressure link 4.

Wheel 2 is made with two outer 5 and two inner 6 conical rims, symmetrically in pairs with respect to the transverse median plane of wheel 2. The latter is connected with body 1 by a hinge coupling, including ring 7 and fingers 8, which ensures its immobility relative to body 1 in the circumferential direction and the possibility of swing in the axial direction. Wheel 3 is made with two conical rims 9, facing towards each other and covering the right rims 5 and 6 of wheel 2 in the engagement zone. A magnetic flux source 10 is located at the base of the rims 9. Wheel 3 zakryspliis) 4, (., - 4 shaft 11.

The pressure link 4 is fixed on the input shaft 12 and represents

a toothed roller 13 with an axis perpendicular to the transmission axis and two end faces (rims 14 facing towards each other, covering left rims 5 and 6 of wheel 2 in the engagement zone and having a source of magnetic flux 15 located at their base. Circles 5, 6, 9 and 14 are made of magnetic conductors.

During operation, as the shaft 12 rotates, the roller 13, as a result of the magnetic interaction of the rims 14 with the left rims 5 and 6, rolls around the wheel 2 and causes the oscillating movement of the latter. The wheel 2, which is stationary in the circumferential direction, is rubbed around the wheel 3. At the same time, due to the difference in the number of teeth of the magnetically interacting right rims 5 and 6 and

rims 9 wheel 3 and the output shaft 11 receive rotation.
