1.范围本国际标准对一系列薄壁半瓦都制订了尺寸和公差。并不指望能从成品库中得到所有列举了尺寸的轴瓦,然而采用标准尺寸却能降低加工成本。本国际标准对于所使用的每种轴承座尺寸都推荐了一系列的壁厚,以便选择轴的尺寸,使之能适应正在考虑的用途中所必需的详细的设计特点。 1. Scope This International Standard sets the dimensions and tolerances for a range of thin-walled half-widths. It is not expected that all of the enumerated bearing pads will be available from the finished product library; however, the standard size will reduce processing costs. This International Standard recommends a series of wall thicknesses for each of the housings used in order to select the size of the shaft to accommodate the detailed design features necessary for the application under consideration.
