Ultra-large outer space environmental simulation experiment module door operation mechanism

Abstract

The invention discloses a cabin door operation mechanism of an ultra-large-type imitation experiment cabin under an outer space environment. The operation mechanism is characterized in that two sides of the lower part of the experiment cabin door are respectively welded with a supporting pillar; the underside of each pillar is provided with a connection plate; the center of the underside of each connection plate is fixedly connected with a semi-spherical pair provided with an inner spherical surface; a semi-spherical pair provided with an outer spherical surface is fixedly connected with a supporting plate; the semi-spherical pair provided with an inner spherical surface and the semi-spherical pair provided with an outer spherical surface form a whole spherical pair; each supporting plate is supported on a corresponding vertical body through two rolling guideways; each vertical body is connected with a driving shaft and a supporting shaft through a bearing; the driving shaft and the supporting shaft are provided with a vertical wheel, wherein, the outer outline of a group of wheels is a smooth cylindrical surface, and the outer outline of another group of wheels is provided with a groove; the underside of two groups of wheels are provided with two guideways. The vertical and the lateral movements of the cabin door operation mechanism of an ultra-large-type imitation experiment cabin all adopt rolling type, so the invention has the advantages of good contact on the joint surface of the cabin body, reliable sealing, light friction, compact structure, convenient operation and maintenance, small occupation area, not occupying the upper space, and the like.

Description

technical field [0001] The invention relates to a door operating mechanism of a super large outer space environment simulation experiment cabin. Background technique [0002] Human beings have a long history of exploring space and outer space, and manned spaceflight engineering has become a priority area for many developed countries such as the United States, Russia, France, and the United Kingdom, including some developing countries. Although my country's aerospace engineering started relatively late, it is developing rapidly, and the day when the Chinese land on the moon is not far away. [0003] The environment of outer space is very harsh for human beings: weightlessness, vacuum, strong ultraviolet radiation, high temperature, deep cold, etc. All kinds of aircraft launched into outer space must be able to adapt to such harsh environments, so all the components that make up outer space aircraft Electronic instruments, meters, mechanical components and their components ar...

AI Technical Summary

Problems solved by technology

Due to the huge size and weight (40t~70t) of the super-large experimental cabin door, and the high center of gravity (greater than 7m), the design of the operating mechanism of the super-large experimental cabin door is a very difficult problem.
