A landing light drive mechanism

Abstract

The invention provides a driving mechanism for a landing light, which includes a motor, a brake, a planetary reducer, a front fixed end cover, a first bearing, a front transmission hollow shaft, a second bearing, a harmonic reducer wave generator, and a harmonic reducer wave generator. Steel wheel, harmonic reducer flexible wheel, rear drive hollow shaft, third bearing, structural frame, rear fixed end cover, lampshade, lamp holder, connecting rod and connecting corner block. In the present invention, the harmonic reducer, planetary reducer, etc. are placed inside the driving mechanism of the landing light, so that the driving mechanism of the landing light has a simple structure, a small number of parts, small volume, compact structure and light weight; The reduction ratio is large, the bearing capacity is high, the transmission efficiency is high, the operation is stable, the gear gap is small, and the transmission precision is high. Under the action of long-term load, the gear is not easy to wear, and the landing light will not shake.

Description

technical field [0001] The invention relates to the field of lamp driving mechanisms, in particular to a landing lamp driving mechanism. Background technique [0002] Landing lights are installed on the aircraft to illuminate the area in front of the aircraft when the aircraft is operating at night on taxiways and runways. When not in use, the landing lights can be stowed flush with the outer surface of the aircraft, reducing the aircraft's air resistance. Existing landing light drive mechanisms suffer from a number of disadvantages. In particular, the existing driving mechanism of the landing light uses common gears for transmission, so that in order to achieve a certain output torque requirement, the overall structure size is too large, which increases the air resistance of the aircraft. Another disadvantage of ordinary gear transmission is that the gears under heavy load wear out quickly, and the larger gear gap causes the landing lights to shake obviously, which cannot...

Problems solved by technology

Existing landing light drive mechanisms have many disadvantages

In particular, the existing landing light driving mechanism uses ordinary gears for transmission. In order to achieve a certain output torque requirement, the overall structural size is too large, which increases the air resistance of the aircraft.

Another disadvantage of ordinary gear transmission is that the heavily loaded gears wear out quickly, and the gear gap becomes larger, resulting in obvious shaking of the landing lights, which cannot provide stable lighting for the driver.
