Description

Technical field

The invention relates to a gearbox with a toroidal link and is used in the transformation of the rotation of this linkage into motion of outgoing links located on its central axis into gears of mechanical and electromechanical devices.

BACKGROUND OF THE INVENTION

A gearbox is known, consisting of an axle-mounted bearing body having transverse bushings with annular openings in which axially bearing elastic circular rings are arranged on a toroidal surface, having part of the transverse bushings having a dental floss [1].

This solution does not allow for bilateral, gradual or rotary movement of output shafts centered on the central axis of its toroidal surface, which diminishes its functionality.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a transmission with a toroidal rotary unit and increased functionality.

The problem is solved by means of a transmission including a shaft-mounted bearing body having transverse bushings with annular openings in which elastic circular rings are arranged, arranged on a toroidal surface. According to the invention, at least one circular ring is hinged, forming the circumferential edges of a pair of pyramidal arrays with vertices lying in a common central axis pointing in different directions. The arms of one pyramidal grille are symmetrically arranged between the arms of the other pyramidal grille, at the top of each of which there is an end sleeve to which the respective arms are pivotally attached and outlet members are connected.

The outlet units may be fixedly connected to the respective end sleeves.

The outlets may have axial bearings and be connected to their respective end bushes by threaded connections.

The shoulders of one pyramidal grid can be connected to one circular ring and the shoulders of the other pyramidal grid to another circular ring.

The arms of the two pyramidal grids can be connected to a single circular ring.

The arms of one pyramidal grid can have a length equal to the maximum radius of the toroidal surface.

To the circular rings of the pair of pyramidal gratings may be hinged the shoulders of a second pair of pyramidal gratings, the tips of which have end bushings connected pivotally to the corresponding shoulders of the second pair of pyramidal gratings.

An advantage of the invention is the increased functionality, given the transformation of the toroidal rotation into a two-way stepwise movement of two output shafts and the possibility of rotation about their axes in the case of a secondary transformation.

Use of the invention

When at least one transverse sleeve 3 is rotated, through its floss 38, the circular rings 5 rotate about the curved axis of the toroidal surface 6. In this case, the diameter of the circular rings 5 changes and they drive the arms 7, 8 of the pyramidal grids 9, 10. Pyramidal gratings 9, 10 move the reciprocating end bushings 14,15, and their corresponding outlet units 17, 18 (Fig. 4). Using threaded connections 19 according to FIG. 5, the outlet units 17, 18 rotate about the central axis of the toroidal surface 6. Thus, the rotational motion of the toroidal body 2 is transformed into a progressive movement of the end sleeves 14,15, and by a second transformation this progressive movement is converted into rotational motion. outgoing units 17.18. The gearbox is reversible, which allows the circular rings to rotate on the toroidal surface 6 and, together with them, the transverse bushings 3 when actuating the outlet units 17, 18. 8 embodiment drives two pairs of end bushes 14,15 and 32, 33, extending the functionality.
