The Actuating System Analytical Of The Electric Submersible Progressive Cavity Pump

The system of oil extraction of ESPCP (Electric submersible progressive cavity pump) places generator, have removed slender sucker rod under well, the key problem of developing this system is the power export requirement of solving high torque and the low rotational speed of progressive cavity pump, this is that design suits the reduction gear and flexible drive that the progressive cavity pump applies under well. The research of this paper is in the transmission of oscillating tooth mesh theory, theory of tooth form, structural theory, theory of Kinematc and Dynamics, at the same time, combine the research of other domestic and international scholar, have designed roller oscillating tooth reduction gear under well (radial size biggest is 114mm, power is 15KW), it is little to have realized the power export requirement of the high torque and the low rotational speed of roller oscillating tooth reduction gear under well.In the paper, the transmission of designed roller oscillating tooth reduction gear adopts oscillating tooth gear drive without exception, one-stage reduction gear and two-stage reduction gear have joined through spline coupling band; The joining way of shock wave thimble and oscillating tooth adopts the biserial bearing of without inner ring of needle bearing, and directly adopts bearing outer ring as shock wave thimble; Center wheel of two-stage reduction gear and center wheel of two-stage reduction gear passes through taper thread, and center wheel is fixed; As soon as the flange of input end and center wheel of one-stage reduction gear, the flange of export end and center wheel of two-stage reduction gear makes monobloc structure.This paper takes off the overall structure of oscillating tooth reduction gear using of the theoretical knowledge of finite element, contact stress and toplolgy, for oscillating tooth reduction gear to carry out design, establishment monochrome topological graph of the kinematic chain of oscillating tooth reduction gear, at the same time also establishment kinematc and dynamics mathematical model of oscillating...
