Constructive Particularities of an Equatorial Spherical Hypocycloid Automatic Machine
Journal Title: RECENT - Year 2010, Vol 11, Issue 29
Abstract
Technical development is one of the paths of human evolution. New technologies and products emerge, are developed and applied, including new types of machine tools. Research made by Transilvania University of Brasov, Romania has led to the elaboration of a new class of automatic presses, called the “hypocycloids”. These exploit some special features of the plain hypocycloid curves and the planetary mechanisms with internal gearing that can generate such trajectories. Latest research has highlighted the possibility of extending this class of machines, in terms of the conception of spatial hypocycloid automatic machines. Research targets so far the spherical hypocycloid automatic machines, highest priority approach receiving / being given to the equatorial ones. In this sense, was already developed a unique, initial concept, for which the patenting procedure has been initiated. Having as reference the kinematic scheme of an equatorial spheric hypocicloid automatic machine, it has been elaborated a constructive and functional virtual model in Pro Engineer Wildfire. The primary scope of this paper is to present some of the structural features of this automatic press in conjunction with the operating principle of this machine.
