Double-shaft swinging and rotating mechanism based on driving gear ring structure

Abstract

The invention belongs to the technical field of electric control and aerospace dynamics, and particularly relates to a double-shaft swinging and rotating mechanism based on a driving gear ring structure. The double-shaft swinging and rotating mechanism based on the driving gear ring structure is high in reliability and working performance. The double-shaft swinging and rotating mechanism based on the driving gear ring structure comprises a first servo motor 1, a second servo motor, a first cylindrical gear 2, a first bevel gear, a second cylindrical gear 3 and a shell body. The double-shaft swinging and rotating mechanism based on the driving gear ring structure is structurally characterized in that a bevel gear ring 8 is arranged in the shell body, and a third bevel gear 18 is arranged on the shell body; the center of the first cylindrical gear 2 is connected with a rotating shaft of the first servo motor 1, a center shaft of the second cylindrical gear 3 is fixedly connected with the shell body, and the first cylindrical gear 2 is engaged with the second cylindrical gear 3.

Description

technical field [0001] The invention belongs to the fields of electric control technology and aviation power technology, and in particular relates to a two-axis swing mechanism based on a transmission gear ring structure. Background technique [0002] Thrust vectoring technology allows part of the engine thrust to be turned into a control force, replacing or partially replacing the control surface; no matter how large the angle of attack is and how low the flight speed is, the aircraft can use this part of the control force to control, which increases the controllability of the aircraft sex. Since the control force is directly generated, and the magnitude and direction are variable, the agility of the aircraft is also increased. [0003] In recent years, the drone industry has developed rapidly, especially small and medium-sized drones have been used in more and more fields. Diversified mission requirements also put forward higher and higher requirements for the maneuverab...

AI Technical Summary

Problems solved by technology

Excessive exposure of the servo mechanism increases the windward area and brings a lot of resistance to flight

Secondly, servo motors are precision equipment, long-term exposure will reduce system reliability and greatly increase maintenance costs, so it is not practical

Moreover, due to structural reasons, most of the existing two-axis swing mechanisms have a swing dead zone, and it is difficult to complete omnidirectional tilting.
