What are the characteristics of Aeromodel gear?

Aviation model gear is a mechanical part used to transmit power, enabling rotational motion and power transmission through meshing. In model aircraft, gears are mainly used for power transmission between the engine or motor and propeller, and are the core component of the model aircraft transmission system.

Advantages

Applicability of different materials:

Steel gear: high strength, suitable for high load scenarios; Plastic gears: lightweight, suitable for small model aircraft; Composite gears: Combined with lightweight and high strength, suitable for high-performance model aircraft

Features of different specifications:

Module: The basic dimensional parameters of the gear determine the load-bearing capacity and transmission ratio of the gear; Number of teeth: The more teeth a gear has, the higher the transmission ratio, but the weight will also increase; Bore size: The diameter of the hole on the gear used to insert the shaft, and the appropriate hole diameter must be selected according to the diameter of the gear shaft.

If you want to buy it, it is recommended to consider from these aspects: fixed-wing aircraft aircraft recommends that spur gears or helical gears be preferred, which can be used for propeller drives; if it is a multi-rotor aircraft aircraft aircraft, it may require lighter gears. If you pay more attention to the accuracy and durability of gears, high-precision gears are suitable for model aircraft that require fine adjustments, while strong durability gears are suitable for high-strength usage scenarios.
