本文以我国生产的几种常用抽油机为例,对游梁式抽油机的主体、主要构件及减速器的参数进行了优化设计及其应用效果的探讨。优化结果表明,效果是明显的:优化并圆整后的四杆机构,其扭矩因数比原来减小约6％,从而可降低功率消耗;游梁、横梁和连杆优化后都比原设计的重量减轻约10％,从而可节省很多钢材;减速器优化后,两级齿轮副的承载能力提高约12％。 In this paper, several kinds of commonly used pumping units produced in our country are taken as examples to optimize the parameters of main body, main components and reducer of the beam pumping unit, and to discuss the application effect. The optimization results show that the effect is obvious: the optimized and rounded four-bar mechanism can reduce the torque factor by about 6% compared with the original one, so as to reduce the power consumption. The optimized beams, beams and connecting rods are better than the original design Weight reduction of about 10%, which can save a lot of steel; gear reducer optimized, two-stage gear pair carrying capacity increased by about 12%.
