Introduction of GB/T 1149.14-2008

本部分规定了活塞环型号为DSF-C、DSF-CNP、SSF、GSF、DSF、DSF-NG和SSF-L的螺旋撑簧油环的基本尺寸特征。螺旋撑簧油环的铸铁环体推荐采用 ISO 6621-3规定的级别为10的材料，有特别要求的可选用级别为20～50的材料。油环表面和相应的撑簧槽设计，可根据制造厂的推荐，选用普通型或镀铬型。螺旋撑簧油环的切向弹力可以在很大的范围内变化，其详细说明和推荐值见第6章。螺旋撑簧油环的环高常规范围为3mm～8mm，按0.5mm或1.0mm间隔递增。表15～20规定了目前使用的英制环高4.75mm（3/16″）螺旋撑簧油环的尺寸。本部分适用于气缸直径小于或等于200mm的往复式内燃机用的螺旋撑簧油环。在类似条件下工作的压缩机用的螺旋撑簧油环也可参照使用。
