ECCENTRICALLY CYCLOIDAL ENGAGEMENT OF TOOTHED PROFILES HAVING CURVED TEETH

摘要

The invention relates to mechanical transmissions for transforming the rotational motion to the rotational or reciprocal one, applying the toothed engagement of gears and it can find its application in cylindrical, bevel or planetary gearboxes and rack gears. One of the engaging profiles represents the gearwheel with at least two helical teeth. Operating segments of each tooth flank of this gearwheel are outlined in principal cross-sections by arcs of the circumference, eccentrically shifted with respect to the center of the gearwheel rotation. Conjugating helical teeth of the second profile are outlined in the same cross-section by segments of cycloidal curves. Tips and troughs between teeth can have any shape, not intersecting with the gearwheel teeth.
