Embodiment Construction

[0013] attached figure 1 and figure 2 Shown is the axonometric view of the transmission screw rod structure of the carbon fiber composite material of the present invention. It can be seen in the illustration that the screw rod is composed of the screw rod main body [1], joint 1 [2], joint 2 [3], pin [4], glue Adhesive [5], the main body of the screw rod is made of full carbon fiber material M55J, on this basis, the composite material is reinforced, and its molding adopts mature processes such as molding and winding to complete the molding of the screw rod. The transmission part adopts trapezoidal screw teeth, and double-start threads are adopted at both ends of the screw rod. The nominal diameter of the thread is not less than 26mm, the pitch is 8mm, and the lead is not greater than 16mm. The joint is connected to the main body of the carbon fiber screw rod 1; the adhesive 5 is selected from J133 structural glue, which is used for the connection between the joint and the mai...

Abstract

The invention discloses a carbon fiber composite transmission screw rod, comprising: a joint 1 [2], a screw main body [1], a joint 2 [3], a pin [4], and an adhesive [5]. The invention solves the problem that some satellite loads need large-scale translational motion. At the same time, the carbon fiber screw rod also has the characteristics of self-lubrication, anti-cold welding, zero expansion, light weight and good compatibility, which effectively guarantees the smooth and high reliability of the load translational movement.

Description

technical field [0001] The invention relates to the technical field of moving parts of spacecraft, in particular to a carbon fiber composite transmission screw rod used for aircraft, especially for satellite transmission parts. Background technique [0002] With the development of satellite technology, moving parts used in satellites are becoming more and more extensive, and transmission parts with large-scale translational motions are also frequently used. The commonly used transmission parts often use metal materials. Due to the large thermal deformation of metal materials, the transmission accuracy and reliability of transmission parts are affected. Therefore, this limits the working temperature range of metal transmission parts, and even limits the use of related moving parts on satellite spacecraft. [0003] In addition, with the development trend of lightweight spacecraft, the weight of each load on the spacecraft is required to be smaller and smaller, and metal trans...
