# What does a smaller spur gear do?

## What does a smaller spur gear do?

A bigger pinion or smaller spur gear makes the vehicle have more top speed, at a decrease in acceleration. It’s most likely that gearing up will make everything run a bit hotter, and shorten run times. A smaller pinion or larger spur gear has the opposite effect.

## What is a 48p gear?

Well 48p is the pitch of the teeth and 90t is the number of teeth on the gear.so its a 48° pitch gear with 90 teeth. its always important to make sure the spur gear and pinion gear are the same pitch.

Is bigger spur gear better?

A bigger spur= more acceleration/ less top speed. A smaller spur= more top speed less accl.

### What is 48DP gear?

Gears – Spur – 48DP – 20 Degree – Aluminium 2024 and 5052 aluminium. DP stands for Diametrical Pitch and is an imperial measurement system. FairlocTM Hub Type require controlled shaft tolerances between 0.0025 and 0.0203 mm Clearance. 48 Diametrical Pitch. Approx 1.66mm between teeth.

### What is 48DP?

The teeth are slightly larger than 48dp (imperial). 48 dp is what you have on the left. 32-48-64 dp I believe stand for 32-48-64 teeth per inch. So the higher the number the smaller the teeth. 64 dp is real tiny and only used for 1/12 pan cars in general.

What are spur gears used for for kids?

For this reason spur gears are used in low-speed applications and in situations where noise control is not a problem, and helical gears are used in high-speed applications, large power transmission, or where noise abatement is important. The speed is considered high when the pitch line velocity exceeds 25 m/s.

#### How far apart should my gears be?

(108+48)/32 =4.875 which is equal to N so half of that number (2.4375”) would be the ideal center to center distance between the 108 tooth spur gear and the 48 tooth pinion gear. This means that the sum of the 2 (32 pitch) gears must equal 156 to fit within the preset center to center distance of 2.4375”.
