AN OUTLOOK ON THE TRANSMISSION ERRORS OF NON-CIRCULAR GEARS DESIGNED BY SUPERSHAPE CENTRODE HYPOTHESIS

Abstract


The paper deals with both the generation and the transmission errors analysis for a specific non-circular gears train. Starting from one of the Gielis supershape as the driving gear pitch curve, an analytical procedure is applied to generate the mating gears teeth flanks. The simulation of meshing is further developed, introducing assembly errors for the gear mounting. The transmission errors are correlated with the variation of the centrodes curvature, offering information on the influence the modification of the gears pitch curve geometry, related to the assembly errors, has on the gears contact pattern. From the simulation performed, it was observed that meshing interval in ideal condition is greater compared to the case when the clearance is introduced.
