Self-locking two lug anchor with incremental counterbore floating nuts with MJ threads for aerospace
Standard in brief
Scope of Application:
本文件规定了航空航天用带沉头窝的MJ螺纹双耳托板游动自锁螺母(以下简称自锁螺母)的结构和尺寸,强度等级为900 MPa1)/235 ℃2), 900 MPa1)/315 ℃2)和900 MPa1)/425 ℃2)。
1) 当使用最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的最小拉伸强度载荷,而不会发生破坏。
2) 螺母承受最高使用温度后,恢复到室温,不会永久改变其原始特性,最高使用温度取决于螺母的材料或表面处理状态。
本文件适用于航空航天用带沉头窝的MJ螺纹双耳托板游动自锁螺母的设计。
