Problems solved by technology

[0003] In the field of mechanical transmission, the common ways to achieve linear reciprocating motion are: connecting rod mechanism, rack and pinion mechanism, screw transmission mechanism, belt chain transmission mechanism and rope transmission, etc., which can only realize reciprocating motion and do not have the function of unfolding.
The expandable mechanisms commonly used in the aerospace field, such as hinges and extension mechanisms, do not have the function of linear reciprocating motion or are limited by quality and life, so they cannot be used for linear reciprocating motion.
Therefore, the current mechanism cannot realize the functions of on-rail deployment and linear reciprocating motion.

Abstract

The invention relates to a space tethered large deployable linear reciprocating motion mechanism which comprises a middle mounting plate, a left mounting plate, a right mounting plate and sliding block parts, and the middle mounting plate and the two mounting plates are provided with sliding rail parts; driving parts are respectively arranged at the left and right ends of the middle mounting plate; one ends of the two side mounting plates are respectively connected with the left end and the right end of the middle mounting plate through hinges, and at the ends, the two side mounting plates arerespectively provided with a first pulley assembly; second pulley assemblies are respectively arranged at the other ends of the mounting plates on the two sides; a transmission rope is arranged on the sliding block part and comprises a left rope section and a right rope section, one ends of the two rope sections are arranged on the sliding block part, and the other ends of the two rope sections are connected with the driving part on the same side through the first pulley assembly and the second pulley assembly on the same side to form a transmission link. In-orbit unfolding and reciprocatinglinear motion of the mechanism are achieved through one set of rope transmission assembly, and the mechanism has the advantages of being simple in structure, light in weight, low in cost, large in stroke, low in assembling precision requirement and the like.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a large-scale deployable rectilinear reciprocating mechanism of a space tether. Background technique [0002] With the development of spacecraft in the direction of large-scale, the linear reciprocating motion mechanism is required to be able to achieve a longer movement distance. At the same time, due to the limitation of the size of the launch vehicle fairing, it is required to be in a retracted state during the launch phase, and to be released and deployed after entering orbit, that is, It is required that the mechanism can realize two functions of on-rail deployment and linear reciprocating motion. [0003] In the field of mechanical transmission, the common ways to realize linear reciprocating motion include: connecting rod mechanism, rack and pinion mechanism, screw transmission mechanism, belt chain transmission mechanism and rope transmission, etc., which often only re...
