The principle of definability of motion of the kinematic chain with two degrees of freedom and with one input on the basis of interconnection of parameters of the hydrostatical converter and closing transmission is developed.

It is shown that situations in decision-making can be significantly enhance by introducing an indicator that successfully describes a set of basic properties of an item. The main provisions of the article are accompanied with exampl

Meshing Limit Line of Normal Arc-Toothed Cylindrical Worm Drive,The conjugate line of meshing limit line is roughly located in the middle of the worm gear tooth surface. The meshing limit line of the worm drive cannot be eliminated via adjusting the designing and operating parameters, and therefore the existence of the meshing limit line is an inherent feature f
