Abstract

The invention provides a grid rudder transmission mechanism for a space transporter. The grid rudder transmission mechanism for the space transporter comprises a supporting column, a wall panel, an actuator, a main shaft, a rocker arm, a space ring, a large lock nut, a small lock nut, an end cover, a pin cover, two specially-made pins, an adjusting shim, a dual-column full roller bearing and two tapered roller angular contact bearings. One end of the supporting column is connected with the wall panel, and the other end of the supporting column is connected with the end cover. The main shaft issequentially provided with the dual-column full roller bearing, the large locknut, the rocker arm, the space ring, the two tapered roller angular contact bearings and the small locknut in series. Themain shaft can freely rotate with the support of the three bearing together. A key groove of the rocker arm is used in cooperation with a key groove in the main shaft. An actuator fixed rod is connected with the wall panel through one specially-made pin. An actuating rod is connected with the rocker arm through one specially-made pin. The actuating rod of the actuator axially extends and contracts to drive the rocker arm so as to drive 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 transportation vehicle for space application load at present. With the increasing demand for launch of space application payloads, the average annual launch times of launch vehicles has also increased significantly compared with the past. The impact of secondary disasters caused by high-frequency rocket launches is even more serious. With the economic development of the landing zone and the increase of population density, the security situation of the landing zone is getting worse. Each evacuation of the landing area involves multiple departments such as medical treatment, fire protection, transportation, communication, electric power, civil affairs, emergency response, forestry, and human and armed forces, and the scale of evac...
