发动机飞轮壳

[中文适用范围]： 本SAE标准规定了发动机飞轮壳体和配套变速箱壳体法兰的主要尺寸和公差。它还定位了曲轴法兰面或变速箱导向孔（或导向轴承孔）相对于壳体SAE法兰面的停止面。 本文件不涵盖飞轮壳体与发动机曲轴箱后部配合面的设计，也不涵盖壳体壁和加强筋的设计。壳体强度分析和壳体材料的选择也被排除在外。 本文件适用于任何可以使用SAE No.6至SAE No.00尺寸飞轮壳体安装变速箱的内燃机。 1.1 目的 本文件旨在实现“发动机飞轮壳体”和“配套变速箱壳体”法兰设计的标准化，以确保兼容性。 [外文原描述]： This SAE Standard specifies the major dimensions and tolerances for Engine Flywheel Housings and the Mating Transmission Housing Flanges. It also locates the crankshaft flange face or the transmission pilot bore (or pilot bearing bore) stop face in relation to housing SAE flange face.This document is not intended to cover the design of the flywheel housing face mating with the engine crankcase rear face or the design of housing walls and ribs. Housing strength analysis and the selection of housing materials are also excluded.This document applies to any internal combustion engine which can utilize SAE No. 6 through SAE No. 00 size flywheel housing for mounting a transmission.Cross Reference: ANSI/B1.1,ANSI/Y14.5,ISO7648,ISO7649,J1033,J1172,J542,J543,J615,J616,J621
