Abstract

The invention provides a buffer mechanism of a docking device. A copper sleeve is arranged on the back side of a space between a shaft and a shaft sleeve; a linear bearing is arranged on the front side of the space between the shaft and the shaft sleeve; an axial spring is arranged between a shaft sleeve end cover flange and a shaft back end cover; a radial spring is arranged between a damper sleeve and a damper pull rod; a gravity compensation block sleeves the shaft sleeve in a front outer shell; an end cover is connected between a bearing outer cover and a bearing outer shell; a disc spring set is arranged on the end cover between the bearing outer cover and the bearing outer shell; two bearing shafts are mounted on the bearing outer cover; inner covers of ball bearings are arranged on the bearing shafts; outer covers of the ball bearings are arranged on universal joints; two symmetric bearing mounting shafts are arranged on the shaft sleeve; the inner covers of the ball bearings are arranged on the bearing mounting shafts; and the outer covers of the ball bearings are mounted on the universal joints by a bearing inner cover. One set of buffer mechanism is designed to reduce the peak value of collision contact force, to prolong the docking collision contact time and to assist realization of smooth docking of non-cooperative satellites.

Description

technical field [0001] The invention relates to a buffer mechanism of a docking device, belonging to the technical field of buffer mechanisms. Background technique [0002] In a modern society with increasingly advanced science and technology, the scope of human activities has expanded to space. According to statistics, the average number of satellites to be launched every year in the world today is about 80-130. However, not all satellites can be correctly put into orbit and serve, and some satellites will fail or be damaged. These satellites that fail or are abandoned after completing their missions will remain in the universe and become space junk, which will not only endanger the safety of other spacecraft, but also occupy a large amount of orbital resources. Therefore, how to realize the capture of satellites in space has become the focus of attention of all countries in the world. [0003] Target satellite acquisition technology in space has many implications, such a...
