Abstract

The invention provides a separating speed on-orbit adjustable device and a manufacturing method thereof, comprising an outer cylinder, a push rod, a thrust spring, a thrust adjusting slider, a screw rod, a screw rod positioning bracket, an articulated bearing, a coupling, a motor driving assembly that are arranged in series in the axial direction, the screw rod is positioned by the articulated bearing and the screw rod positioning bracket, and is fixed relative to the outer cylinder, the thrust adjusting slider has the freedom to make linear motion in the outer cylinder. The motor driving assembly is connected with the rear end of the screw rod through a coupling and drives the screw rod to rotate; the threaded portion of the screw rod front end is matched with the threads on the thrust adjusting slider to form a screw rod transmission, which drives the thrust adjusting slider to move in the axial direction, adjusts the compression stroke of the thrust spring, thereby realizing the thrust adjustment of the spring push rod device, and finally realizing the on-orbit adjustment of the separation speed. The invention has the advantages of integrally lightweight, compact structure and on-orbit thrust adjustment, and is particularly suitable for the field of small satellite on-orbit deployment and separation, and has wide application applicability.

Description

technical field [0001] The invention relates to the structure and mechanism of a spacecraft, specifically a device with an adjustable separation speed on orbit and a manufacturing method thereof, which is suitable for the separation of satellites and rockets, the separation of two devices, and the separation of star cabins in spacecraft such as satellites, especially for the separation of small satellites. Rail deployment separation and other fields. Background technique [0002] With the development of aerospace technology, the multi-satellite launch mode has gradually been widely used in the aerospace field, especially the small satellite field, due to its high space utilization rate in the fairing, convenient and efficient deployment of satellites and other characteristics. The adjustment of the on-orbit separation speed of small satellites waiting for separation products has become a new potential demand. Therefore, the existing conventional spring push rod device is di...
