Motor Pinons

When selecting an RC motor pinion, it's important to choose one that is compatible with your motor shaft and main gear. It's also important to consider the intended use of the vehicle, as well as the motor's power and RPM rating, in order to choose a pinion gear that will provide the desired performance.

Different pinion gear sizes will affect the gear ratio, with larger pinion gears providing more torque and slower speed, and smaller pinion gears providing less torque and faster speed. It's important to choose the right pinion gear size for your intended use to ensure that the vehicle's performance is optimized.

It's also important to check the condition of the pinion gear regularly and replace it if it shows signs of wear or damage, as worn or damaged pinion gears can affect the vehicle's performance and may cause further damage to the drivetrain.

The main features of an RC motor pinion include the number of teeth, pitch, material, and bore size.

Number of Teeth: The number of teeth on the pinion gear determines the gear ratio of the vehicle. Pinion gears with more teeth provide more torque and slower speed, while those with fewer teeth provide less torque and faster speed.

Pitch: The pitch of the pinion gear refers to the distance between teeth and is usually measured in terms of module (metric) or DP (imperial). It is important to choose a pinion gear with the correct pitch to ensure that it meshes correctly with the main gear.

Material: Pinion gears are typically made from steel, aluminum, or brass. Steel is the strongest and most durable, but also the heaviest. Aluminum is lighter but not as strong as steel, while brass is softer and can wear more quickly.

Bore Size: The bore size of the pinion gear refers to the diameter of the hole in the center of the gear that fits onto the motor shaft. It is important to choose a pinion gear with the correct bore size to ensure a secure fit onto the motor shaft.

Other features that can be important to consider when selecting a pinion gear include the shape of the teeth (such as straight-cut or helical), the thickness of the gear, and whether or not the gear is compatible with a specific type of motor or vehicle. It's important to choose a pinion gear that is compatible with your specific motor and vehicle, and that is appropriate for the intended use of the vehicle.
