3D Parametric Design and Performance Test of Precision Cam Divider

Abstract

The precision cam divider is mainly used for intermittent indexing step motion between two vertical staggered shafts and extensively applied in machinery of textile, package, tobacco, food, pharmacy and machining center, etc. [ [. With progress of modern science and technology, higher speed, efficiency, life and quality are required for mechanical transmission mechanisms on automats and automatic lines, as a result, higher requirements are raised for properties of the precision cam divider. In spite of advantages of high transmission speed, high locating precision, high indexing precision, good reliability, good dynamics performance, simple structure and long lifetime, etc. of the precision cam divider, artificial design is very cumbersome, in which design and machining of globoidal indexing cam are more complicated [ [. This paper develops CAD/CAM system for globoidal indexing cam by means of Pro/E system development platform and parameterizes design of globoidal indexing cam and transposition disc so as to simplify design interface and shorten design cycle of product, and mean while performs dynamic assembly, simulation and test of product performance to improve product quality and operating efficiency.
