Modelling concave globoidal cam with indexing turret follower: A case study

摘要

This paper describes a computer-aided design for design of the concave globoidal cam with cylindrical rollers and indexing turret follower. Three models with different modelling methods are made from the same input data. The input data include some basic dimensions of the globoidal cam system and a table of angular input and output displacements of the cam and the follower. The cam model must have no interference with the rollers when their motions are simulated in assembly conditions. In this study, Pro/ENGINEER Wildfire 2.0 is used for modelling the cam, simulating motions and checking interference and errors of the system.
