标准摘要
[中文适用范围]： 本国际标准规定了上部非圆成型具有自锁功能的MJ螺纹花键驱动螺母的尺寸，分类为：1 100MPa/425℃、1 100MPa/650℃、1 210 MPa/425℃、1 210 MPa/730℃、1 550 MPa/235℃、1 550 MPa/425℃、1 550 MPa/600℃。 本国际标准仅适用于航空航天产品标准的编制。 注：1) 相当于使用更高强度等级的螺栓进行测试时，螺母在环境温度下能够承受而不断裂或开裂的最小拉应力。 2) 环境温度恢复后，螺母能够承受的最高温度，且不会永久改变其原始特性。 最高温度由密封圈材料或表面处理决定。 [外文原描述]： ISO 9157:2002 specifies the dimensions of spline-drive nuts, with MJ threads and a self-locking feature achieved by forming the upper portion out-of-round, for classifications: 1 100 MPa/425 °C, 1 100 MPa/650 °C, 1 210 MPa/425 °C, 1 210 MPa/730 °C, 1 550 MPa/235 °C, 1 550 MPa/ 425 °C and 1 550 MPa/600 °C. ISO 9157:2002 is only applicable for the compilation of aerospace product standards.
