Problems solved by technology
On the one hand, this increases the size of the device, on the other hand, it brings additional frictional energy loss
One of the most important drawbacks of gears is the loss of frictional energy due to the fact that the connecting teeth of the wheels slide on each other for most of their meshing time
This makes power transfer efficiency significantly lower even with proper lubrication applied

Embodiment Construction
[0071] In order to show the main parts and the main features of the roller transmission and gear mechanism introduced by the invention, first an example of the basic design is shown, in which the two bodies are two rotationally symmetrical wheels whose axes of rotation form oblique lines with respect to each other And include an angle. FIG. 1 shows a schematic diagram of the design, comprising a first wheel 10 and a second wheel 20 and their respective axes of rotation 11 and 21 . In this specification, "wheel" refers to a rotationally symmetrical body that is rotatable about its axis of symmetry but fixed along its axial direction. Each body has a rotationally symmetrical inner or outer surface centered on the axis of rotation of the body, on which surface a roller guide track is formed. These surfaces will be referred to as orbital surfaces. Said orbital surface is delimited by two separate limiting surfaces, which are planes generally, but not always, perpendicular to the...

A roller transmission and gearing mechanism with a driving body, roller means and a driven body; the driving body is coupled to the driven body by means of the roller means, the bodies are guided with a single degree of freedom, and define respective roller guide tracks thereon, the tracks contact the roller means and determine the movement of the roller, which contact the roller guide tracks along rolling curves, the roller guide tracks start and terminate at respective pairs of limit surfaces, and the roles of the driving and driven bodies can be interchanged, furthermore the distances between points of the rolling curve on the driving body and on the driven body are different, the rolling means move with pure rolling motion, and for all point-pairs on the rolling curves the respective tangential planes are parallel to each other, the velocities of the contacting pairs of points are identical but have opposite signs, in the contacting points the action lines of forces intersect the central axes of the roller means, and the lengths of the rolling curves of the driving and driven bodies are equal, and before and after the contact points the rolling curves have angularly inclined tangential planes.
Description
technical field [0001] The present invention relates to a roller (rolling body) transmission (transfer) and transmission mechanism (roller transmission and gearing mechanism), which includes a driving body, a roller device with a corresponding center or central axis and a driven body, wherein the driving body passes through The roller arrangement is engaged to the driven body, the driving body and the driven body are guided in motion with a single degree of freedom, and respective roller guiding tracks are defined on the driving body and the driven body, said tracks contact the roller arrangement and determine the relative movement of the roller arrangement with respect to the associated body, the roller arrangement contacting the roller guide rails along respective rolling curves, the roller guide rails starting and ending at the corresponding pairs of limiting surfaces at the driving body and the driven body , the roller assemblies move along their associated roller guide ra...
