ANALYSIS OF THE SPHERICAL FIVE-BAR MECHANISMS WITH TWO DWELLS OF OUTPUT LINKS

Authors: N. Davitashvili, O. Gelashvili


Abstract:

Research into spherical five-bar hinged mechanisms with two DOF, four revolute and one sliding kinematic pairs and slider-mobile guide (S-MG) mechanisms with dwells of the output link is given in the paper. Is revealed that spherical five-bar with four revolute and one sliding pair in the middle of slider stroke has two long dwells of output link, and spherical crank-rocker five-bar mechanisms have two dwells of the output link at the extreme positions. The obtained results of analysis of the spherical five-bar mechanism with two dwells of the output link represents the new scientific direction in spatial (spherical) five-bar mechanisms two DOF.

Keywords: spherical five-bar hinged mechanism; two degrees of freedom; spherical slidermobile guide (S-MG) mechanisms; two dwells of output links.
