Abstract

The invention provides an electric self-unlocking separation nut and a spacecraft, and relates to the technical field of frontiers of science and technology such as carrier rocket separation and stararrow separation. The electric self-unlocking separation nut comprises a driving motor, a motor nut, a casing, a plurality of split nuts and a plurality of unlocking balls; an output shaft of the driving motor is fixedly connected with the motor nut and is used for driving the motor nut to move along the axial direction of the inner wall of the casing; the plurality of split nuts sequentially support against to define a ring; each split nut corresponds to at least one unlocking ball; one end of each unlocking ball supports against the outer wall of one split nut, and the other end of each unlocking ball supports against the inner wall of the motor nut; at least one annular groove for accommodating the plurality of unlocking balls is formed in the inner wall of the motor nut. The electric self-unlocking separation nut is simple in structure; in addition, by arranging the unlocking balls, the problem of clamping in the unlocking process can be improved, the separation nut is enabled to be quickly unlocked, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technological frontier technical fields such as carrier rocket separation, satellite rocket separation, etc., and in particular relates to an electric self-unlocking separation nut and a spacecraft. Background technique [0002] The separation nut is an axial connection and radial unlocking connection unlocking device, which is widely used in the connection and separation of sections on spacecraft. The principle of separating the nut is mainly to cut a complete nut into parts, and use the ferrule to tighten the split nut. When separating, the ferrule and the split nut will move relative to each other, and the restraint will be released, and the split nut will be forced to open to achieve the purpose of unlocking. . [0003] At present, the separation nuts used in my country's launch vehicles and satellites are mainly connected by pyrotechnics to the separation nut unlocking device. This device can provide a very large conn...
