用于抽油机的新型三环减速器

设计的新型三环减速器主要由圆弧齿同步齿形带、小带轮、大带轮、曲柄轴、传动环板、输出轴、外齿轮和箱体等组成。介绍了减速器的结构、工作原理、特点以及用于抽油机的可行性。传动环板及转臂偏心轴惯性力和惯性力矩的计算结果表明 ,这种减速器传动机构的惯性力和惯性力矩理论上是完全平衡的。根据滑动轴承理论 ,新型三环减速器设计了油膜浮动机构 ,使减速器在运行中均载、减振效果明显 ,受力较为合理。

New three-ring gear reducer on pumping unit

Newly developed three ring gear reducer is comprised of synchronous belt, big and small pulleys, crankshaft, drive ring plate, output shaft, external gear and case. The working principle and characteristics of the new reducer are introduced, and practicability of the reducer to pumping units is discussed. Calculation of the inertia force and inertia force moment on the drive ring plate and tumbler eccentric axis shows that the inertia force and inertia force moment of the reducer's driving mechanism are fully equilibrant. According to the theory of the journal bearing, an oil film floating mechanism for the three ring reducer is designed to make the reducer operate with uniform load and good absorption of vibration.
