INTRODUCTION OF A WAVE FACE KINEMATIC REDUCER IN PUMPING TECHNOLOGIES FOR THE EXTRACTION OF HIGH-VISCOUS OIL IN EXTREME CONDITIONS

Abstract

The relevance of the research is caused by the need of ensuring small overall dimensions and mass of gear speed reducers, which allows them to be placed together with piston pumps in hard-to-reach places and extreme conditions for the extraction of high-viscous oil. The ratio of the mass of the gear speed reducer to the nominal torque at the output shaft is the main criterion of the technical level of gear speed reducer. Therefore, the need to create new types of gear speed reducers with small dimensions and mass is very relevant. The main aim of the research is to determine the transmission ratio of the wave face kinematic reducer and the dependence of the gear block size and its angular velocity on a nutation angle. Objects: wave face kinematic reducer as an integral part of piston pumps during high-viscous oil mining in extreme conditions. Methods: Willis method, analytical method, numerical methods for solving systems of linear equations, the theory of mechanisms and machines and theory of gearing. Results. The paper considers the problem of creating a wave face kinematical reducer with small dimensions, which allows it to be placed together with piston pumps in hard-to-reach places and extreme conditions for the extraction of high-viscous oil. The transmission ratio of the speed reducer was determined by two methods (Willis method and analytical method) and the dependence of the gear block size on the nutation angle θ. In addition, the upper limit value of the nation angle was determined, in which the reducer works stable. It is important to note that, the wave face kinematic reducer does not require the fulfillment of the conditions for the equality of the center distances, which expands its optimal design. In addition, its kinematics does not impose restrictions on the choice of gear modules or tooth pitch, which expands the set of possible ratios of the gear teeth number and the range of transmission ratios.
