The multi-redundancy rotary motor-driven mechanism for driving airplane exhaust valve comprises a driving mechanism, an output mechanism (3) and an exhaust valve execution mechanism (4) connected with the output mechanism (3), wherein the driving mechanism comprises a power controller (5), a main motor (1a), an auxiliary motor (1a), a main reducer (2a), an auxiliary reducer (2b) and a worm gear (6); the main motor (1a) and the auxiliary motor (1a) are Brushless DC Motor, which are connected with the output end of the power controller (5) through wire, respectively; the worm gear (6) is an electric self-locking worm gear with the electric self-locker connected with the auxiliary motor (1a) and the auxiliary motor (1a). The invention overcomes the shortage of the single-redundancy rotary motor-driven mechanism in prior art and has the advantage of simple structure and high reliability. When a motor and a reducer have failures, the standby motor and reducer can work normally.
Description
technical field [0001] The invention relates to an electric mechanism on an aircraft, more specifically, it is a redundant rotary electric mechanism for driving an exhaust valve of an aircraft. Background technique [0002] Airplanes, especially large ones, because there are many people on board, in order to ensure safety, some safety guarantee mechanisms are set up, such as controlling the pressure exhaust valve of the aircraft cockpit and cockpit, which is an electric valve driven by an electric mechanism. When the aircraft breaks down at high altitude, the pressure in the cockpit and cockpit will exceed the physical limit of the crew, endangering the safety of the crew on board. At this time, it is necessary to use the pressure exhaust valve to always adjust the pressure of the cockpit and cockpit normally. , to ensure the safety of personnel, so higher requirements are put forward for the reliability of the exhaust valve. The electric mechanism of the existing exhaust v...
