Unmanned aerial vehicle transmission shaft with auxiliary supporting sleeve pipe and manufacturing method thereof

Abstract

The invention discloses an unmanned aerial vehicle transmission shaft with an auxiliary supporting sleeve pipe. The unmanned aerial vehicle transmission shaft comprises a transmission shaft body, wherein a spline which is in transmission connection with an output gear of an engine is arranged at one end of the transmission shaft body, a flange plate used for being fixedly connected with a main shaft of an unmanned aerial vehicle is arranged at the other end of the transmission shaft body, the transmission shaft body is sleeved with the auxiliary supporting sleeve pipe, one end of the auxiliarysupporting sleeve is fixedly connected with the flange plate, the other end of the auxiliary supporting sleeve is fixedly connected with the transmission shaft body, and the length of the auxiliary supporting sleeve pipe is equal to half of the length of the transmission shaft body. The invention further discloses a manufacturing method of the unmanned aerial vehicle transmission shaft with the auxiliary supporting sleeve. Alloy materials which are obtained by smelting of multiple kinds of metal are made into the unmanned aerial vehicle transmission shaft with the auxiliary supporting sleevepipe, so that the unmanned aerial vehicle transmission shaft has high-strength constitutive property, strong wear resistance, and good abrasion resistance and impact resistance, and effectively prolongs the service life of the unmanned aerial vehicle transmission shaft, and meets the requirements of rapid development of the unmanned aerial vehicle.

Problems solved by technology

[0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by the on-board computer; compared with manned aircraft, UAVs are often more suitable for tasks that are too "dumb, dirty or dangerous"; UAVs can be divided into military and civilian uses according to the application field. For military use, UAVs are divided into reconnaissance aircraft and target aircraft; The application of drone industry is the real rigid demand of drones. At present, it is mainly used in aerial photography, agriculture, plant protection, micro selfie, express delivery, disaster rescue, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspections, and disaster relief. , film and television shooting, romantic manufacturing and other fields have greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology; the drive shaft of drones is mainly used for large helicopters. The UAV transmits the engine power to the main shaft of the UAV, and the main shaft of the UAV drives the rotor to rotate. Therefore, the transmission shaft transmits the torque and bears all the reaction force, and also bears the vertical force and driving force from the main shaft of the UAV. and the reaction force and bending moment caused by the lateral force. Therefore, the structure and strength of the drive shaft of the UAV are very important, and its wear resistance and impact resistance are also important. Currently, large helicopter-style UAVs use The drive shaft cannot meet the needs of the rapid development of large helicopter-style drones
