带有螺栓孔的切边横截面装载机

[中文适用范围]： 该文件已被宣布为“稳定”，并且将不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。用于 SAE J1057a 中定义的装载机铲斗上使用的切削刃。这些尺寸仅适用于轧制和机加工型材。切削刃横截面厚度最大限制为 35 毫米。螺栓固定式齿适配器很少用于切削刃厚度超过 35 毫米的装载机铲斗。此推荐做法仅适用于直切削刃，定义为前缘和后缘平行并因此具有恒定横截面的切削刃。按照本推荐做法所指示的添加螺栓孔的总体横截面选自“切削刃横截面装载机直”、SAE J1303 FEB85 所示的横截面。选择是基于适应螺栓固定齿适配器的最小截面宽度要求。指定带有螺栓孔的直切削刃横截面的尺寸，用于按照 SAE J731d 的规定将螺栓固定式齿适配器安装在装载机铲斗上。本推荐实践的目的是描述适用于螺栓固定齿安装的横截面，并确定螺栓孔尺寸和相对于切削刃横截面的位置。因此，推荐的做法为未来螺栓固定齿适配器的标准化奠定了基础。 [外文原描述]： For cutting edges used on buckets for loaders defined in SAE J1057a. The dimensions are applicable to rolled and machined sections only. Cutting edge cross section thickness is limited to a maximum of 35 mm. Bolt-on tooth adapters are rarely used on loader buckets with cutting edge thicknesses in excess of 35 mm. This recommended practice applies only to straight cutting edges defined as those whose leading edge and rear edge are parallel and thus are of constant cross section. Overall cross sections to which bolt holes were added as indicated by this recommended practice were selected from those indicated per "Cutting Edge—Cross Sections Loader Straight," SAE J1303 FEB85. Selection was based on minimum section width requirements to accommodate bolt-on tooth adapters.NOTE—For some heavy-duty applications, cross sections with larger blunts, greater bevel angles, and larger bolt holes may be required.Cross Reference: J1057,J1303,J731
