A grid rudder transmission mechanism for space transport

Abstract

The invention provides a grid rudder transmission mechanism for aerospace vehicles, which includes a support column, a wall plate, an actuator, a main shaft, a rocker, a spacer, a large lock nut, a small lock nut, an end cover, a pin Cover, two special pins, adjusting spacers, double row full complement roller bearings, two tapered roller angular contact bearings. One end of the supporting column is connected with the wall plate, and the other end is connected with the end cover. Double-row full complement roller bearings, large lock nuts, rockers, spacers, two tapered roller angular contact bearings, and small lock nuts are installed in series in series on the spindle axis. The main shaft can rotate freely under the common support of three bearings. The keyway on the rocker mates with the keyway on the spindle. The fixed rod of the actuator is connected with the wall plate through a special pin, and the actuating rod is connected with the rocker through a special pin. The actuating rod of the actuator stretches axially to drive the rocker, which in turn drives the main shaft to rotate.

Description

technical field [0001] The invention relates to a grid rudder transmission mechanism for an aerospace vehicle, belonging to the technical field of mechanical device design. Background technique [0002] The launch vehicle is the most important space transport vehicle for the current space application load. With the increasing launch demand of space application payloads, the annual average number of launches of launch vehicles has also increased significantly compared with the past. The impact of secondary disasters caused by high-frequency rocket launches is more serious. With the development of the economy and the increase in population density, the safety situation of the landing areas has become increasingly intensified. Each evacuation of the fallen area involves multiple departments such as medical treatment, fire protection, transportation, communication, electricity, civil affairs, emergency response, forestry, and human and military affairs, and the scale of evacuat...
