Abstract

The invention discloses a single-shaft rotary two-way buffer device for an aircraft docking mechanism; it includes: a cylindrical body composed of a fixed shell, a shell, and a baffle, in which a rotating shaft and a shaft connected to the aircraft collision body are installed; Plane scroll springs are respectively installed on the and shafts. Each set of springs has two sections, separated by a movable housing; the inner end of the scroll spring is fixed on the rotating shaft or shaft, and the outer edge end is fixed on the movable housing. ; Cam disc groups are respectively installed in the front sleeve and rear sleeve of the rotating shaft or shaft; there is a bump on the rotating shaft or shaft and the cam disc respectively; when the movable housing is rotated and the pre-tightening torque of the spring reaches the specified value, the The bumps fit together and are tightened with screws to preload the spring. The invention also discloses a double-shaft rotating two-way buffer device. The invention solves the problem of the large-angle buffer stroke of the aircraft docking mechanism, and achieves the beneficial effects of simple structure and high reliability.

Description

Technical field [0001] The invention relates to space vehicle equipment in the aerospace field, and in particular to a rotating two-way buffer device in a space vehicle docking mechanism. Background technique [0002] Relevant technologies for realizing the rotational buffering function include seat belts on automobiles, which use the multi-rotation nature of the scroll spring to achieve a large-stroke buffering effect. The disadvantage is that it can only realize buffering in one direction, and there is no specific mechanism to complete multiple functions. Turn number rotary output. [0003] Currently, in the field of spacecraft docking mechanisms, there is a device that can realize a two-way transmission and buffering function. This device uses a spiral torsion spring to achieve rotational buffering in two directions. Its shortcoming is that its buffering function relies on a torsion spring. It is realized by tightening and releasing, so the rotation capacity is less than...
