Aerospace-nuts,anchor,self-locking,floating,self-aligning,single lug,with MJ threads—Dimensions
Standard in brief
Scope of Application:
本文件规定了航空航天用MJ螺纹带沉头窝的成组游动托板自锁螺母(以下简称“螺母”)的结构和尺寸,强度等级为1100 MPa1)/120 ℃2),1100 MPa1)/235 ℃2),1100 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MJ螺纹带沉头窝的成组游动托板自锁螺母的设计。
