The influence of skew and deflection of the rotating shafton force factors arising in gear joints

Abstract

Important and priority tasks for the industry of Ukraine are the reduction of costs for the creation of the final product, the reduction of the cost of maintenance of the construction of machines and mechanisms, the restoration of the outdated production base and the attraction of new technologies, mechanisms and equipment. That is why, increasing the efficiency, reliability and service life of machine units, which are used in conditions of misalignment of the axes of the connecting shafts, which are caused by the deflection of the rotating shaft in the mechanisms, which are connected to each other by an intermediate shaft with the help of compensating devices, and are intended for the transmission of effective power from the engine to the consumer, and, as a rule, is the most important part of any power plant, is an urgent task, and the further development of the modern machine-building industry depends on its successful solution. At the same time, the effectiveness of machine mechanisms directly depends on the productive work of gear mechanisms that are part of them, namely mechanical gears and gear couplings, which are widely reflected in almost all industries. Thus, the purpose of the work is to assess the influence of the deflection of the rotating shaft on the force factors that arise when the axes are misaligned in the gear joints of machine units. The effect of skew and deflection of a shaft rotating at a high frequency on the force factors for some toothed joints was investigated. It was found that the values of the dynamism coefficients do not exceed 1.05-1.15, and the dynamic components of these power factors can reach 30-50% of the level of their static components
