标准摘要
[中文适用范围]： 本文件根据ISO 12301规定了带或不带法兰的薄壁半轴承圆周长度的检查，并描述了必要的检查方法和测量设备。 薄壁半轴承具有柔性，在自由状态下不符合圆柱形轮廓。 这是半轴承的周长只能在约束载荷下通过使用专用测量设备进行测量的原因之一。 此外，可以使用与本文件所示不同的测量设备，只要该设备的测量精度符合第17条给出的规格。 本文件不包括分型线锥度的测量。 本文件适用于薄壁半轴承，其规格在 ISO 3548-1 中给出。 [外文原描述]： This document specifies, according to ISO 12301 , the checking of the peripheral length of thin-walled half bearings with or without flange, and describes the necessary checking methods and measuring equipment. Thin-walled half bearings are flexible and, in the free condition, do not conform to a cylindrical profile. This is one reason the peripheral length of the half bearings can only be measured under a constraining load by use of specialized measuring equipment. In addition, measuring equipment different from that illustrated in this document can be used, provided the measuring accuracy of the equipment is consistent with the specifications given in Clause 17 . This document does not include the measurement of the parting line taper. This document applies to thin-walled half bearings, the specifications of which are given in ISO 3548 ‑ 1 .
