Variable pitch motor hub unit developed by NSK

Support flying car and drone flight technology

In areas such as metropolises with heavy traffic, mountainous areas with inconvenient traffic, and islands surrounded by the sea, people have higher and higher expectations for flying cars that can truly replace cars as a mode of transportation. In addition, the demand for drones to carry photographic equipment for aerial photography or monitoring, light cargo transportation, agriculture, disaster relief, hobbies,etc. is also increasing.

Therefore, in order to make car flying a reality as soon as possible, the Japanese Ministry of Economy and information industry and the Ministry of Land and transportation have set up the "Public and Civilian Council for Air Traffic Reform" Companies are developing prototypes in accordance with the development roadmap proposed by the agreement, which will not only ensure the same level of safety and reliability as the aircraft, but also further improve the performance of quietness and cruising range.

The "motor hub unit equipped with an electric variable pitch mechanism" developed by NSK is one of the most important parts in flying cars. It not only supports the rotation of the propeller, but also changes the thrust and lift of the flying car by adjusting the direction of the propeller blades. . The mechanism uses bearings and ball screws manufactured by NSK. The product introduction is as follows:

1. Motor hub unit with electric variable pitch mechanism

The prototype of the drive unit adopts high-quality angular contact ball bearings, thrust needle roller bearings, ball screws and other NSK products. It can not only support the rotation of the propeller, but also accurately change the rotation posture of the propeller blades to control thrust and lift to achieve front and rear free flight in left and right directions.

2. High-reliability bearings widely used in small drones and industrial drones

The seal ring that does not invade moisture even in rainy weather, and the original research and development of stainless steel material can prevent bearing from rust, to ensure high reliability under any weather conditions. In addition, NSK is developing bearings with properties of smaller, lighter, and low-friction and high-speed rotating for needs of energy-saving and high-speed requirements of flight.
