CUTTING PARAMETERS DEFINITION FOR KINEMATIC OPTIMISATION OF SPIRAL BEVEL GEARS

Abstract

The contact analysis of uniform tooth height epicyclical spiral bevel gears stemming from Klingelnberg´s Cyclo-Palloid System has an important role in preliminary design. The simultaneous generation of gear surfaces and contact simulation is the basis of the analysis. A numerical program for theoretical contact identification has been developed. Longitudinal settings of the contact patterns or contact across the surfaces from tooth root to tooth top were obtained as a function of machine settings. The influence of each cutting parameter was isolated and is discussed for kinematic optimization.
