Title Modeling a new pumping machine design in Kompas

Abstract

The article deals with crank-slider mechanisms of the 3rd class, implementing the required cyclogram with an approximate stand, the output link of which moves along the guide, the position of which is set. Analytical expressions for calculating the parameters of the kinematic scheme of the mechanism are obtained. Both flat four-link and more complex multi-link crank mechanisms are used in crank presses. During one reciprocating movement (stroke) of the slider, the input crank makes a complete revolution, which corresponds to the cycle of the press. Twice per cycle, at extreme positions, the speed of the slider should be zero, thus, the movement of the output link is accompanied by the appearance of inertial forces. Technological requirements determine the specific nature of the movement of the slider, which is provided by the appropriate structure of the actuator or by varying the size of its links.
