The TCI Speedometer Gear Calculator is a valuable tool used in automotive applications to determine the number of teeth required on the speedometer gear for achieving a desired speedometer reading. It works by calculating the necessary teeth based on various input factors.
Formula of TCI Speedometer Gear Calculator
The calculation formula for the TCI Speedometer Gear Calculator is:
Teeth (T) = (Driven Gear Teeth * Vehicle Speed) / (Drive Gear Teeth * Desired Speedometer Reading)
Where:
- Teeth (T) represents the number of teeth needed on the speedometer gear.
- Driven Gear Teeth is the count of teeth on the driven gear, typically located on the transmission output.
- Vehicle Speed indicates the actual speed of the vehicle in miles per hour (MPH).
- Drive Gear Teeth refers to the number of teeth on the drive gear, commonly found on the speedometer cable.
- Desired Speedometer Reading signifies the target speedometer reading in miles per hour (MPH).
Useful Terms and Conversions Table:
| Term | Description |
|---|---|
| Driven Gear Teeth | Number of teeth on the driven gear |
| Vehicle Speed | Actual speed of the vehicle in miles per hour (MPH) |
| Drive Gear Teeth | Number of teeth on the drive gear |
| Desired Speed Reading | Desired speedometer reading in miles per hour (MPH) |
This table provides an easy reference for common terms related to the calculator, assisting users in understanding and utilizing it effectively.
Example of TCI Speedometer Gear Calculator
Suppose a vehicle has a driven gear with 20 teeth, while the drive gear has 18 teeth. If the desired speedometer reading is 60 MPH, and the actual vehicle speed is 45 MPH, applying the formula would yield:
Teeth (T) = (20 * 45) / (18 * 60)
Teeth (T) = 900 / 108
T ≈ 8.33
Rounded to the nearest whole number, the required teeth on the speedometer gear would be approximately 8.
Most Common FAQs:
A: Yes, this calculator is widely applicable to various vehicles where speedometer gear adjustments are necessary.
A: While the calculator formula is based on miles per hour (MPH), users can convert KPH to MPH before utilizing the calculator.
