内燃机活塞涨圈槽

[中文适用范围]： 没有与此 SAE 标准等效的 ISO 标准。该 SAE 标准确定并定义了活塞环槽特性最常用的术语@指定了槽宽度的尺寸@并演示了活塞槽根部直径的计算方法。本文件的要求适用于在类似条件下工作的往复式内燃机和压缩机的活塞和环，压缩环直径不超过 200 毫米，宽度不超过 4.5 毫米，油环宽度不超过 8.0 毫米。本文档中的规格假设组件是在 20℃（68℃）的环境温度下测量的。本文档中指定的公差代表实际功能限制，并不意味着工艺能力。 [外文原描述]： There is no ISO standard equivalent to this SAE Standard. This SAE Standard identifies and defines the most commonly used terms for piston ring-groove characteristics, specifies dimensioning for groove widths, and demonstrates the methodology for calculation of piston groove root diameter. The requirements of this document apply to pistons and rings of reciprocating internal combustion engines and compressors working under analogous conditions, up to and including 200 mm diameter and 4.5 mm width for compression rings and 8.0 mm width for oil rings. The specifications in this document assume that components are measured at an ambient temperature of 20 °C (68 °F). Tolerances specified in this document represent practical functional limits and do not imply process capabilities.
