Calculating the Manufacturing Parameters of a Shaver and …

Abstract Determination of the parameters of a shaver and roller system for finishing the round teeth of cylindrical gears is considered. Algorithms are proposed for selecting machining pathways appropriate to the gear crown of the shaver and roller system. A mathematical model is derived for calculating the radii of curvature of the convex and concave sides of its teeth.

Construction and design of cycloidal gears

 · Cycloidal gears must always be specially matched to each other and can generally not be exchanged at will! The rolling circles are generally matched to the base circles, i.e. they are in a certain ratio to each other, since the ratio of rolling circle diameter to basic circle diameter determines the shape of the cycloid and therefore the shape of the tooth flank.
