外文资料 抽油机减速箱系统设计 （Pumping reducer system design） Design task Pumping unit is crude oil to the ground from underground lifting one of main production equipment, and common rod pumping equipment has three parts: one is that ground drive equipment pumping unit; The second is, it underground pump hanging in the lower end of the oil pipeline; Three is sucker rod, it will ground equipment for power transfer of sport and underground pump. By motor drives by pumping unit, slowing transmission system and execution system (will turn to reciprocating movement) change driven sucker rod and pump plunger make fluctuation reciprocating movement, so as to realize the crude oil to the ground from the purpose of downhole lifting. Assuming motor rotation of pumping units do uniform motion cycle, for T, sucker rod on time with the next stroke stramework time equal. Stroke S = 1.4 m, blunt times n = 11 times/min, lifting crude oil, because the stroke in the role of the load is equal to the suspension of crude point weight plus sucker rod and piston itself under the weight of 40kN, crude oil for already released, role stramework in the load is suspended points sucker rod and piston itself weight for 15kN. Requirements: (1) according to the mission requirements, pumping the general scheme design of mechanical system, to determine the deceleration transmission system, implement system composition, schematic drawing system solutions. (2) according to the design parameters and design requirements, adopting the optimization algorithm for execution system (actuators) motion size design, optimization goal for sucker rod acceleration as the stroke suspended points minimum, and should make execution system has good power transmission performance. (3) establish execution system input and output (points) between suspension of displacement, velocity and acceleration of relationships, and programming for numerical calculation, drawing a cycle suspended point displacement, velocity and acceleratio
