Abstract: Orthogonal cylinder-bevel gears have been applied since ancient times. The main advantage of such transmission versus the traditional conical one is the possibility of some axial displacement of the gear that significantly simplifies the mounting of the gear. However, the geometric calculations required in the manufacture of this type of transmission are extremely complex. Therefore, effective software, that would simplify the geometric modeling of transmission elements, is needed. The article describes the scope of orthogonal cylinder-bevel gears in modern engineering. An algorithm for the geometric calculation of the elements of cylinder-bevel gear, implemented using the application program module developed by the authors, is presented
