TECHNICAL SOLUTION IN DESIGNING COUPLED GEAR ENGAGEMENTS REGARDING THE DETERMINATION OF INTERFERENCE IN WEAPONS AND MILITARY TECHNIQUES

In the complex realities of the modern industry of Ukraine, an important direction of scientific and technical development is the optimization of technical solutions in the design of coupled gears of kinematic pairs regarding the determination of interference in weapons and military equipment with increased requirements for the degree of complexity of the designed products and shortening the terms of order fulfillment. Given the serious pressure of crisis phenomena in the economy and increased competition on the market, these components force us to carry out work at the most modern technical level. The paper proposes the optimization of the analytical technical solution for designing the contact line between the axes of the coupled gear engagements of kinematic pairs to determine the interference. This will make it possible to reduce the equation to a parametric form, to algorithmize and optimize the modeling of the product, and to design the contact surface of the gear when designing products in weapons and military equipment. The technical solution to the given problem refers to gear-coupled mechanisms of external engagement, the shape of the teeth of the wheels is formed by wrapping the initial contour of the gear rack, and the number of teeth is determined depending on the purpose of the mechanism, the required gear ratio and diametrical dimensions. Such mechanisms are used in various units and units of weapons and military equipment, namely in the form of gear wheels of reducers, winches, planetary and wave gears and as working bodies of pumps, hydraulic motors, compressors and internal combustion engines with straight and helical teeth. To avoid interference at the design stage, it is necessary to analyze the technical curvilinear characteristics of the conjugated surfaces. The application of technical solutions for the description of real surfaces obtained as a result of the creation of a curvilinear model reflects the real physical process of determining interference.
