Design and performance of globoidal indexing cam raceway with steel ball
Abstract：Due to the great influence of the sectional profiles of a cam raceway on both transmission efficiency and bearing capacity of mechanisms,the pre-tightening methods for two sectional profiles of globoidal indexing cam raceways with steel ball,namely single and double arc sectional profiles,and their influence on the pressure angle of a cam and the motion law of an indexing disk were analyzed.The motion simulation of the mechanisms with two sectional profiles was carried out with ADAMS software.The results indicate that the double arc sectional profile offers higher transmission efficiency and more stable output motion of indexing disk.The superiority of the double arc sectional profile of globoidal indexing cam raceways with steel ball is proved.The present results can provide the theoretical foundation for the design of sectional profiles of cam raceways with steel ball.
