标准摘要
[中文适用范围]： 本规范提供了用于石油和天然气行业的游梁式抽油机设计和评定的要求及指南。包括从承载梁到齿轮减速器输入轴之间的所有组件。其中包括：a) 抽油机结构；b) 抽油机齿轮减速器。本规范仅考虑由光杆载荷施加在结构或/和齿轮减速器上的载荷。还包括对封闭齿轮减速器的设计和评定要求，其中渐开线齿形设计包括斜齿和人字齿。本规范中确定的评定方法和影响因素仅限于单级和多级设计，应用于游梁式抽油机，其中任何一级的节线速度不超过 5000 ft/min，且任何轴的转速不超过 3600 rpm。本标准不包括材料的化学性能、设备的安装和维护、游梁式平衡装置、原动机以及齿轮减速器或控制系统之外的动力传输装置。 [外文原描述]： 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 gear reducer input shaft. This includes the following: a) beam pump structures; b) pumping unit gear 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 gear 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 5000 ft/min and the speed of any shaft does not exceed 3600 rpm. This specification does not cover chemical properties of materials, installation and maintenance of the equipm
