    摘要:

    为确保解锁后的分瓣螺母与螺杆有足够的间隙,针对一种直推式分离螺母和利用弹簧抽出螺杆的连接解锁装置,分析其分离过程,并对单侧及双侧螺纹钩挂工况下的压紧杆进行了受力分析;同时,对双侧螺纹钩挂工况下分离螺母的最小分离间隙进行理论计算,计算结果可应用于分离螺母的设计与分析。

    Abstract:

    To ensure enough clearance between the split nuts and the screw, aimed at a separation nut of direct thrust model and connecting-unlocking device using spring extract screw, the separation process was analyzed, and the force analysis of compression rod under one-sided hook and double hooks conditions was carried out. Meanwhile, the minimum clearance of the separation nut under double hooks condition was calculated, the result can be applied to the design and analysis of separation nuts.
