Simulation of Contact Loads in the ANSYS Environment for Non-Involute Meshing

This work analyzes the stress-strain state of contacts with non-involute meshing for cycloid, eccentric and worm gearboxes using ANSYS software. For each of the listed gearboxes, the acting stresses and their distribution, the contact patch and the status of the contacts are examined. The minimum contact area is realized in the cycloid gearbox and the maximum contact area in the eccentric-cycloidal gearing where the eccentric operates in the triaxial stress state. In accordance with the stress-strain state analysis, the highest efficiency should be expected in the cycloid gearbox and the lowest in the eccentric-cycloidal gearboxes. The results obtained has shown that the eccentric-cycloidal gearing has no advantages over the other types of gearing. It has been established that the cycloid gearbox has the best technical characteristics among the types of gearing examined through the stress-state analysis.
