Introduction
The research is performed: (i) in the frames of the UIC-Industry Gear Power Transmission Research Consortium, and (ii) as special projects based on contracts.
The main topic of the research is: Computerized Design, Generation, and Simulation of Meshing and Contact of Aligned and Misaligned Gear Drives.
The main goals are: localization and stabilization of bearing contact, and reduction of transmission errors.
The performed research covers all types of gear drives applied for transformation of rotation between parallel, intersected, and crossed axes. In addition, the research covers cycloidal gearing applied in screw compressors, Wankel engines, Root's blowers, and pumps.
