Bigger pinion, or smaller spur gives a better top speed, but less acceleration. Smaller Pinion, or larger spur gives better acceleration, and a lower top speed.

People also ask, what does a smaller pinion gear do?

Smaller pinion = More torque, slower top speed, better acceleration, consequently better runtime, less heat and stress on motor. up to a point that is True, but Under gearing a motor can also overheat and burn it up.

Also Know, what is the difference between a spur gear and a pinion gear? According to manufacturers Such as Boston Gear a "Spur Gear" can have any tooth form and still be referred to as a "Spur Gear" if it has straight teeth. The Term "Pinion" refer`s to the smallest Gear or Wheel driving another wheel as mentioned by Bob and Smudgy.

One may also ask, how do pinion and spur gears work?

You can alter your car's gear ratio by using a different pinion or spur gear. The pinion gear is the very small gear that fits onto the motor, and is usually made from some kind of metal. Common metals include Aluminium, Steel and Titanium. The spur gear is the larger gear that the pinion turns.

What does a 4.10 gear ratio mean?

When you hear people refer to numbers like 3.08, 3.73, or 4.10, they're talking about the ratio of the ring-and-pinion gears in the rear axle—hence, the numbers are more accurately 3.08:1, 3.73:1, or 4.10:1. That also means that for every one turn of the ring gear, the pinion will turn 4.11 times.

How many teeth does a pinion gear have?

Summary. Empirically, a pinion with approximately 20 teeth is optimal.

How does a pinion gear work?

Rack and pinion gears are used to convert rotation into linear motion. A perfect example of this is the steering system on many cars. The steering wheel rotates a gear which engages the rack. As the gear turns, it slides the rack either to the right or left, depending on which way you turn the wheel.

What does a bigger spur gear do?

bigger spur gear=more torque, more acceleration, usually less top end speed, things run cooler (batts, motor, esc) and you also should get some more run time.

What is a fast gear ratio?

The lower the number, the faster the car will go with the same number of engine revolutions. The higher the number the better the car will accelerate, but at the expense of high speed cruising. Now for the confusing part of the story. A high numerical gear ratio is called a low gear or low rear end, and vice versa.

Why pinion is smaller than gear?


this is because the radius of pinions is lesser than gears so for a particular load condition torque experienced by pinion will be same as gears torque (= force* perp-dist) since radius of pinion is smaller so more force will be exerted thats why pinion gets deformed while the radius of gear is more than the pinion

Which gear will rotate the fastest?

Gears
  • Faster rotation, less force. The smaller gear turns four times in the time it takes the larger gear to turn once.
  • Slower rotation, more force. The larger wheel has four times as many teeth as the smaller wheel.
  • Teeth lock together. The teeth in both wheels are all the same size.

How do you calculate final drive ratio?

By simply dividing the ring gear tooth count by the pinion gear tooth count, the ratio is determined. For example, if we divide a ring gear with 41 teeth by a pinion gear with 10 teeth we find that the gear ratio is 4.10:1 (41/10 = 4.10). Tire diameter will also have an effect on a vehicle's final drive ratio.

What does 48 pitch gear mean?

When you see 48 or 64 pitch, for example, the number means you can count a certain number of teeth per certain amount of its circumference. So if you have a 48 tooth 48 pitch gear & a 64 tooth 64 pitch gear, both would be the same size in diameter(but that means the 64 pitch gear has smaller, finer teeth).

What is 48p?

The tooth count is how many teeth are on the gear, and the pitch of the gear refers to the number of teeth per inch of the gear's diameter. There are a few common sizes we use in R/C, such as 32-pitch (32P), 48-pitch (48P), and 64-pitch (64P).

What does a spur gear look like?


Spur gears are a type of cylindrical gear, with shafts that are parallel and coplanar, and teeth that are straight and oriented parallel to the shafts. They're arguably the simplest and most common type of gear – easy to manufacture and suitable for a wide range of applications.

How do you calculate spur gear ratio?

The ratio of a given pair of spur gears is calculated by dividing the number of teeth on the driven gear, by the number of teeth on the drive gear.

What does a spur gear do?

Spur gears are a cylindrical shaped toothed component used in industrial equipment to transfer mechanical motion as well as control speed, power, and torque.

What is a group of gears called?

Two or more meshing gears, working in a sequence, are called a gear train or a transmission. A gear can mesh with a linear toothed part, called a rack, producing translation instead of rotation. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system.

What is torque ratio?

A gear train can be analyzed using the principle of virtual work to show that its torque ratio, which is the ratio of its output torque to its input torque, is equal to the gear ratio, or speed ratio, of the gear train.

What do the numbers on a pinion gear mean?


First, the gear ratio is determined by the tooth combination. The number of teeth on the ring gear divided by the number of teeth on the pinion (eg: 41/11 = 3.73) equals the gear ratio. This means that the pinion shaft is roughly 1/3 the diameter of the ring gear for a 3.00 to 1 gear set.

Why are gear teeth angle?

The teeth of a helical gear are set at an angle (relative to axis of the gear) and take the shape of a helix. This allows the teeth to mesh gradually, starting as point contact and developing into line contact as engagement progresses.

Where is bevel gear used?

Bevel gears are used in differential drives, which can transmit power to two axles spinning at different speeds, such as those on a cornering automobile. Bevel gears are used as the main mechanism for a hand drill.
