Глобальный метод повышения эффективности эксплуатации цилиндрических и конических зубчатых передач

Abstract

The disadvantage of the existing cylindrical and bevel gears is the absence of complete mutual contact of all teeth with each other. Each gear tooth comes into contact or comes into contact only with the same tooth of the wheel or with the group of the same teeth of the gear wheel a certain sequence. In the process of running-in and operation all the errors, deviations of the gear tooth will appear when contacted with errors and deviations with the mating tooth of the wheel. There is a cyclic component of the dynamic load and as a consequence: increased noise, vibration. In order to reduce negative factors, it is necessary to increase the degree of accuracy of cylindrical gears, which significantly increases the cost of their manufacture and does not completely eliminate the issues of noise reduction, vibration, and smoothness of engagement. As a result of the study of the operational characteristics of gearing, a method was proposed for calculating the increase in wear resistance, durability and increase smoothness of work by creating and predicting certain gear ratios that determine the non-multiplicity of engagement and ensure the operation of the teeth of the driving gear with all the teeth of the driven gear. To reduce the formation of micro-pittnig, it is necessary to use gear pairs with a non-multiple gear ratio, which will ensure the participation of all teeth in the work and, as a result, uniform wear, as well as choose a lubricant designed to prevent micropitting. Incomplete gearing is characterized by contacting each gear tooth with each tooth of the gear wheel in sequence and ensures accelerated uniform workability of the mating gears, correction of defects in the manufacture and assembly of gears, reduction of vibrations, noise, increased wear resistance and improved smoothness of gears, durability.
