INDUSTRIAL TESTING OF S.ABDRAIMOV'S LEVER IMPACT MECHANISMS IN VARIOUS CONDITIONS
This article discusses the results of approbation and testing of several models of lever percussion mechanisms developed in the laboratory "Theory of Mechanisms and Machines" of the Institute of Mechanical Engineering and Automation of the National Academy of Sciences of the Kyrgyz Republic. For an objective assessment of their effectiveness and efficiency, as well as for forecasting for the future, several sites were selected: the bottom of coal mining, the foundation of the enclosing walls, and the preparation of the well under the water column. The technical characteristics of hammers of models M 50-17, M 20-20 and M 15-21 are given. The main difference is shown in the use of a lighter commutator electric drive with a built-in gearbox (reducer motor) instead of an asynchronous electric motor of a general industrial design of the 4AC100S4U3 type. This made it possible to significantly reduce the weight of the structure and provide the necessary level of electrical safety for the operator without an additional electrical insulation device for the hammer.
