The invention discloses a damping-adjustable hinge, a cabin door structure and a spacecraft. The damping-adjustable hinge comprises a first hinge support, a second hinge support, a sleeve and a pre-tightening device which are made of a first metal material, the first hinge support and the second hinge support are rotatably connected through a rotating shaft, and a first anti-abrasion structure isarranged between the first hinge support and the second hinge support; the sleeve sleeves the rotating shaft and is relatively and fixedly matched with the first hinge support, the sleeve is rotatablymatched with the second hinge support, and a second anti-abrasion structure is arranged between the sleeve and the second hinge support; and the pre-tightening device is arranged on the rotating shaft and tightly presses the sleeve on the second hinge support, and the anti-abrasion structure is made of a second metal material. The whole damping-adjustable hinge is integrally made of metal materials, it can be guaranteed that the whole hinge has good strength and durability so as to adapt to severe environments such as outer space, abrasion during opening and closing is reduced, the service life is prolonged, and the damping of the hinge can be adjusted through the pre-tightening device.
本发明公开了一种阻尼可调铰链、舱门结构以及航天器,该阻尼可调铰链包括由第一金属材料制成的第一铰支座、第二铰支座、套筒及预紧装置,第一铰支座与第二铰支座通过转轴可转动连接且两者之间设置有第一防磨结构,套筒套设于转轴且套筒与第一铰支座相对固定配合,套筒与第二铰支座可转动配合,套筒与第二铰支座之间设置有第二防磨结构,预紧装置设置于转轴上并将套筒压紧于第二铰支座,上述防磨结构由第二金属材料制成;该阻尼可调铰链整体采用金属材料制作,可保证铰链整体具有良好强度及耐用性,以适应外太空等恶劣环境,减少开合时的磨损,延长使用寿命,并可通过预紧装置实现对铰链阻尼的调节。
