## What does 48p mean on a pinion gear?

with 48 pitch gears, one tooth on the pinion is about equal to 3 teeth on the spur.

### What is a 48 pitch gear?

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 are spur gears good for?

Spur gears are used to transfer motion and power from one shaft to another in a mechanical setup. This transference can alter machinery’s operating speed, multiply torque, and allow for the fine-tuned control of positioning systems.

**What does 32P mean on a gear?**

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 module is 48 pitch?**

Spur Gear Conversion (Units in inches)

Diametral Pitch (inch) | Circular Pitch (inch) | Module |
---|---|---|

2.1167 | 1.4842 | 12 |

2.1855 | 1.4375 | 9 |

2.25 | 1.3963 | 11.289 |

2.2848 | 1.375 | 8.59 |

## How do I choose a spur gear?

Determine allowable force on gear teeth, including the factors necessary due to angle of involute of tooth shape and materials selected for gears. Design actual gear systems, including specifying materials, manufacturing accuracy, and other factors necessary for complete spur gear design. prevent surface wear.

### Which gear turns fastest?

In a small/large gear set-up, when the small gear has made a full rotation, the large gear will not have yet completed a full rotation. Thus, the smaller gear makes more revolutions in a given time, rotating at a faster pace than the larger gear.

#### What module is 32 pitch?

1.0 module-refered to as metric 32 is actually a standard 25.4 pitch.

**What is the best type of gears?**

Spur gears are the most widely used gears that can achieve high accuracy with relatively easy production processes. They have the characteristic of having no load in the axial direction (thrust load). The larger of the meshing pair is called the gear and smaller is called the pinion.

**How do you know if gears are compatible?**

When selecting gears and gear racks, you’ll need to know the gear type, pressure angle, and pitch (or for metric gears, module). As long as these three specifications are the same, your gears will fit together correctly.
