Frequently Asked Questions (FAQs)
1. What are the different gears in an RC car?
In an RC car, there are two main gears: the pinion gear, which is connected to the motor, and the spur gear, which is driven by the pinion gear. The spur gear may also include a slipper clutch or be part of a differential in a 4WD car.
2. What is transmission gear ratio in RC car?
The transmission gear ratio, also known as the primary ratio or internal ratio, determines how many times the wheels of the RC car turn for each turn of the spur gear. This ratio is determined by the gears in the transmission and is usually not adjustable in most RC cars.
3. What gear makes an RC car go faster?
To achieve more speed in an RC car, you can use a larger pinion gear or a smaller spur gear. These changes will provide more speed. On the other hand, if you want more torque and acceleration at the expense of top speed, you can opt for a smaller pinion gear or a larger spur gear. It is possible to change one or both gears to achieve the desired effect.
4. How does RC car gearing work?
In an RC car, the pinion gear is connected to the motor's output shaft, while the spur gear is connected to an output shaft in the transmission. By changing these gears, the gear ratio is altered, resulting in different performance characteristics. A higher gear ratio provides more torque and acceleration but lower top speed, while a lower gear ratio offers less torque and higher top speed.
5. Which gears are for which speeds?
The gear ratios and corresponding speeds can vary depending on the specific RC car model. However, generally speaking, first gear is for speeds up to 10 mph, second gear is for speeds between 10 and 20 mph, third gear is for speeds between 20 and 30 mph, fourth gear is for speeds between 30 and 40 mph, fifth gear is for speeds above 40 mph (for five-speed cars), and sixth gear is for cruising speeds above 40 mph (for six-speed cars).
6. Does more teeth on pinion gear mean faster?
The tooth count of the pinion gear and spur gear determines the speed and torque output of an RC car. When the pinion and spur gears have a closer tooth count, the speed is higher. Conversely, when they have a larger difference in tooth count, the torque output is higher. This applies to any vehicle, gear pitch, and tooth count.
7. Is a bigger or smaller spur gear better for speed?
Using a bigger pinion gear or a smaller spur gear in an RC car will increase the top speed but decrease acceleration. However, it's important to note that gearing up may cause the vehicle to run hotter and reduce run times. Conversely, using a smaller pinion gear or a larger spur gear will have the opposite effect, providing more acceleration at the expense of top speed.
