Construction of mathematical models of lever mechanism as a system of equations characterizing the mechanism in each moment. Development application for a full kinematic analysis on example of drive mechanism of one-knife papercutter machine BR-125. Developed an original method for constructing mathematical models of 3rd class lever mechanism on example of drive mechanism of one-knife papercutter BR-125. In the calculations used mathematical programming package «Maple». The method of calculating the kinematic characteristics of discrete units during the working cycle was described. This was determined by the coordinates of the fixed points of chains depending on the angle of rotation of the input chain using the method of geometric bindings. These were based on interpolated using Lagrandzh polynoms and differentiated for velocity and acceleration of these points. As a result of the work were obtained kinematic characteristics (speed, acceleration) of the main points of the mechanism and established framework for power analysis.
