THE COMPARATIVE ANALYSIS OF TWO PANTAGRAPHIC SCHEMES OF MANIPULATION MECHANISMS
The servey has been implemented from the allocation of forceful strain in the kinematic pairs of two schemes multilink pantographic mechanisms, which differs with the amount of driving motors. Such pantographic mechanisms with five cross-shaped groups, with one or two linear drives, for example, with hydraulic culinders which are applied in elevators and manipulators. The survey was implemented for the case of static strain under the axial force of service load, taking into account the gravity links. Analysis showed differences and peculiarities of allocation in the kinematic pairs and in the links of two indicated schemes of mechanisms, that allows to optimize its structure (or construction).
Keywords: pantagraphic mechanism, kinematics, hinged lever mechanism, force analysis.
