游梁式抽油机中游梁支撑轴的研究与分析

Research and Analysis of Supporting Shaft for Walking Beam in Walking-beam Pumping Unit

以游梁式抽油机的主要磨损部件游梁支撑轴为研究对象,对其进行运动分析。同时建立游梁式抽油机的机构简化模型及游梁支撑轴的力学模型,分析游梁支撑轴在工作载荷下的受力和载荷分布。所做研究为优化油梁支撑轴设计,避免游梁支撑轴损坏,延长游梁式抽油机使用寿命提供了参考。

The motion analysis was carried out by taking the supporting shaft i.e. a major wearing part of the walking beam pumping unit as the subject for investigation. At the same time, the simplified model of the walking beam pumping unit and the mechanical model of the support shaft for walking beam were established to analyze the stress and load distribution of the support shaft for walking beam under the working load. The findings could provide a reference for optimum design of the support shaft for walking beam in order to avoid damage to the support shaft and extend the service life of the walking beam pumping unit.
