Q: Does a bigger pinion gear increase speed?
A: Yes, a bigger pinion gear can increase speed. Larger pinion gears provide a higher gear ratio, which can result in faster rotational speed of the motor and, consequently, faster overall speed of the gearbox or drivetrain. However, this might come at the cost of reduced torque.
Q: What does more teeth on a pinion gear do?
A: More teeth on a pinion gear generally mean a higher gear ratio, which can lead to:
- Increased speed: The motor will turn the pinion gear faster, increasing the speed of the driven gear or wheel.
- Decreased torque: Higher speed often comes at the expense of torque, so the system might struggle with heavier loads or inclines.
Q: How many teeth are on 3.73 gears?
A: The 3.73 gear ratio refers to the ratio of the number of teeth on the ring gear to the number of teeth on the pinion gear. To achieve a 3.73 ratio, the pinion gear typically has fewer teeth than the ring gear. The exact number of teeth can vary depending on the specific gear set.
Q: What pinion gear makes RC faster?
A: In RC cars, a larger pinion gear makes the vehicle faster by increasing the gear ratio. This allows the motor to turn the wheels faster, resulting in higher speeds. However, it's essential to balance this with appropriate gear ratios and motor capabilities to avoid overheating or damaging components.
Q: What's better, 3.73 or 4.10 gears?
A: The choice between 3.73 and 4.10 gears depends on your specific needs:
- 3.73 Gears: Offer a balance between speed and torque. Suitable for general-purpose use.
- 4.10 Gears: Provide more torque and acceleration at the expense of top speed. Better for off-road or towing applications where additional torque is beneficial.
