About Kinematic Parameters of the Spatial Hypocycloidal Automatic Machine for Cold Forming
Journal Title: RECENT - Year 2010, Vol 11, Issue 30
Abstract
Plane hypocycloidal automatic machines, forming an entire family, are a Romanian original concept developed at Transilvania University of Brasov. Recent researches emphasize the possibility of developing this group of automatic machines for cold forming by a new subgroup, potentially very diverse, the spatial hypocycloidal automatic machines. Although the slide blocks of these automatic machines realize a linear motion, the element which drives it describes a spatial hypocycloid, hence the name given to automatic machines in question. In the main cinematic chain of the automatic machine, there is present a sun-and-planet gear with conic gears that generate spatial hypocycloidal trajectories, used as a mechanism for transforming rotary motion into linear-alternative one. This paper presents, with adequate demonstrations, the law of motion of the driving element, the law of motion characterizing the slide blocks of these automatic machines, and its cinematic parameters.
