以履带拖拉机导向机构上的零件插入耳环为例,对比、解析键槽对称度的几种检测方法,目的和意义在于想通过解析加深检验人员对国家标准的进一步理解,尽快统一键槽对称度检测方法,避免因测量方法不同引发质量纠纷。插入耳环(零件号:A32-9A,见图1),是履带拖拉机导向机构中具有安全功能的零件,其键槽对称度能影响着拖拉机的行驶方向。插入耳环的主要技术要求是键槽对
The purpose and significance of analyzing and comparing several detection methods of keyway symmetry with the example that the parts on the crawler tractor guide mechanism are inserted into earrings are intended to deepen the inspection personnel to further understand the national standards and to unify the keyway symmetry detection method as soon as possible, Avoid quality disputes caused by different measurement methods. Insert the earrings (part number A32-9A, see Figure 1), a safety-oriented part of the tracked tractor-guidance mechanism whose keyway symmetry affects the tractor’s direction of travel. The main technical requirements for inserting earrings are keyway pairs
