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 a vertical slide with a roller at an end, located in the guides slidably vertically with the center of mass of the slider is on its symmetry axis, located on the cam rotation axis by dezaksazha. 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, the pressure cam angles to the vertical slider values ​​reactions relations and forces of interaction between its parts from changing their relative position. The proposed stand vertical slide guides are movable along vertical guides which are fixed to the frame to move them along a horizontal guide and rigid fastening of both a guide and pressure sensors are provided at the intersection with a vertical slide. It is possible to carry out investigations of the influence of pressure changes in the angles of the cam to a vertical slider on the magnitude of forces applied thereto. 2 yl.
