STAND FOR RESEARCH cam mechanism

摘要

The invention relates to laboratory equipment and can be used in teaching laboratories on theoretical and applied mechanics, the theory of mechanisms and machines, as well as parts of machines of technical universities, colleges and technical schools. Known mechanism consisting of a cam drive, which rests on the slide with a plate at its end located in vertical guides slidably the slider center of mass located at its axis of symmetry intersecting the rotation axis of the cam. The main drawback of the known cam mechanism lies in the fact that he has a constant position of support, which does not allow to carry out research on the determination of dependencies, for example, cam pressure angle values ​​on the slider, the values ​​of reactions relations and forces of interaction between its parts from changing their relative position. The proposed stand vertical guides associated slider further inputted frame adapted movable along the horizontal guide frame and rigidly fixed thereto and provided with a pressure sensor in the point of contact with the slider. It is possible to carry out investigations of the influence of pressure changes in the cam angles on the slide with a flat plate on the magnitude of forces applied thereto. 2 yl.
