一种生成直线运动的大行程抽油机设计

摘要

本文论述的是一种能降低惯性冲击并可实现机器的内啮合行星齿轮生成直线运动的大行程抽油机,该机型与传统的直线式抽油机相比,抽油率较高,耗电量较低,寿命长,使用维修方便.不但给油田带来巨大的经济效益,而且也有不可估量的社会效益.%A long-stroke oil pumping unit is presented in the paper which is able to reduce inertial impact and generate linear motion via its inside engaged gear.Compared with traditional linear oil pumping unit, it can bring about great economic benefits to oil manufacturers and immeasurable social benefits owing to its high efficiency, low power consumption, long useful life and easy maintenance.
