Abstract

The invention discloses a single-ball type air-floating pulley device combining an air floation ball bearing and an air floation plane thrust bearing, belongs to the field of space flight and aviation, and aims to solve the problem that the zero-gravity simulation precision in the vertical direction in a spacecraft ground simulation test by a traditional counterweight method cannot be well improved due to the influence of friction. The device comprises an air floatation rotation ball assembly, an air floatation rotation ball socket assembly and a rotation side air floatation thrust supporting assembly. The air floatation rotating ball assembly is located on the air floatation rotating ball socket assembly, meanwhile the two sides of the air floatation rotating ball assembly are clamped and supported by the rotation side air floatation thrust supporting assembly.

Description

technical field [0001] The invention relates to a technology for reducing friction in a zero-gravity simulation test, and belongs to the field of aerospace and aviation. Background technique [0002] With the continuous development of aerospace technology, the weight and volume of spacecraft continue to increase, the structure becomes more and more complex, and the functions are constantly improved. The tasks that the same spacecraft needs to perform are also becoming more and more diverse. Therefore, in order to ensure that the spacecraft can operate safely and stably in orbit, and at the same time be able to complete the scheduled tasks well and achieve the expected technical indicators, it is necessary to carry out a large number of ground simulation tests during the design and development of the spacecraft. verify. Moreover, as the functions of the spacecraft are becoming more and more perfect, in order to comprehensively assess the spacecraft in all aspects, the requir...
