适用范围/摘要
本规范提供了石油和天然气行业用游梁式抽油机的设计和额定值的要求和指南。包括承载杆和减速器输入轴之间的所有部件。这包括以下内容:梁泵结构；抽油机齿轮减速器；和抽油机链条减速器。本规范仅考虑光杆载荷施加在结构和/或齿轮减速器上的载荷。还包括封闭式减速器的设计和额定值要求，其中渐开线齿轮齿设计包括螺旋齿轮和人字齿轮。 本规范中确定的额定方法和影响仅限于适用于游梁式抽油机的单级和多级设计，其中任何级的节线速度不超过5000 ft/min，任何轴的速度不超过3600 r/min。本标准不包括材料的化学特性、设备的安装和维护，梁式平衡装置、原动机和齿轮减速器外的动力传输装置或控制系统。
This specification provides the requirements and guidelines for the design and rating of beam pumping units for use in the petroleum and natural gas industry. Included are all components between the carrier bar and the speed reducer input shaft. This includes the following:beam pump structures;pumping unit gear reducer; andpumping unit chain reducer.Only loads imposed on the structure and/or gear reducer by the polished rod load are considered in this specification.Also included are the requirements for the design and rating of enclosed speed reducers wherein the involute gear tooth designs include helical and herringbone gearing. The rating methods and influences identified in this specification are limited to single and multiple stage designs applied to beam pumping units in which the pitch-line velocity of any stage does not exceed 5,000 ft/min and the speed of any shaft does not exceed 3,600 r/min.This standard does not cover chemical properties of materials, installation and maintenance of the equipment, beam type counterbalance units, prime movers and power transmission devices outside the gear reducer, or control systems.
