Possibilities of Compact Spherical Joint Creating

Abstract

In recent applications of output kinematic strings of manipulation and automation techniques, industrial robots and manipulators and other motional mechanisms is using of spherical joint not extensive. The reason is in difficult connections to the driving unit or units. The problem is generally solved by using of two or three joints with spherical joining in serial connection turned usually of 90 degrees. Using this construction design brings enlarging of weight and dimensional parameters. The invention solves the problem by using spherical surface provided by toothed grooves and at least two driving pinions according to patent number PV 2010-264 exhibited on 6th.April 2010.
