In this work, case of rotations transformation between arbitrary crossed shafts (axes of rotations) by means of high kinematic joints, which elements configure active tooth surfaces of hyperboloid gear mechanisms is treated. |Analytical dependencies, defining the law of rotations transformation are illustrated. This law of transformation in this concrete case is a constant function of the relations of the angular velocities of the movable links of the spatial three-link gear mechanism. The shown functions are applicable both to the synthesis of the studied transmissions, and for the determining and control of the kinematic errors of these transmissions, caused by manufacturing and assembly errors.

The study presents a brief description of the type’s software, applicable to the synthesis and design of gear transmissions. The main accent is put on the approach to the computer synthesis, for which the optimization process is carried out by the method of directed search of the optimal variant of a synthesized mechanism. The specific features of the programs, applied by the authors, oriented to the synthesis of spatial gear mechanisms with linear contacting teeth with face meshing (Spiroid and Helicon) are studied in detail.

A prototyping of miniature hyperboloid gear drives and ultrasonic motors is presented. A new type ultrasonic motor is experimentally tested.
