Abstract

The invention provides a connecting lock for spacecraft docking, relates to a connecting lock and aims at solving the problem that an existing connecting lock mechanism is large in weight and low in reliability. The connecting lock for spacecraft docking comprises a stud support connected with a driving-end spacecraft and a nut support connected with a driven-end spacecraft and further comprises a motor, a motor blocking plate, a coupler, a bearing, a bearing end cover, a stud, a nut, a connecting key, a compression spring and a nut end cover, wherein the top face of the motor is fixed on the bottom face of the stud support through the motor blocking plate, the top end and the bottom end of the stud respectively extend into the nut support and the stud support, a motor shaft is connected with the bottom end of the stud through the coupler, the bearing is arranged between the stud and the stud support, the lower end of an angular contact ball bearing is fixed by a shaft shoulder on the stud support, the upper end of the angular contact ball bearing is fixed by the bearing end cover, and the nut is peripherally positioned to the nut support through the connecting key. The connecting lock for spacecraft docking is used for rigid connection of the driving spacecraft and the driven spacecraft.

Description

technical field [0001] The invention relates to a connection lock, in particular to a connection lock used in the docking process of a spacecraft. Background technique [0002] From the 1960s to the present, humans have carried out a large number of docking practices, and the former Soviet Union alone has carried out more than 100 space connections. Human beings have realized from long-term space docking practice that for space docking mechanisms, two characteristics are the most important, namely weight and reliability. However, today's spacecraft docking is mainly carried out by impact. Whether it is a "rod-cone" docking mechanism or a "peripheral" docking mechanism, the capture lock on the capture mechanism requires a certain impact force. Under the action of the active capture lock, the active capture lock hook is knocked open, and the capture connection with the passive capture lock receiver can be realized. But collisions will cause certain problems. The instantaneou...
