Selecting the shape of centroids of round and non-round gears

Abstract In the design of gears, the most important task is to obtain centroids. Features of selection of centroids of round and non-round gears obtained by means of functions of harmonious form are considered, process of its formation is shown. Analytical dependencies are presented describing the geometry of the centroid of a round and non-round gearwheel. An example of an implementation of a mechanism based on dependencies describing the construction of a centroid is given.
