Chains Per Hour Calculator

Calculate the chains per hour based on input parameters like chain speed, pitch diameter, and gear ratio for machinery and engineering applications.

Input Parameters

Calculation Results

Calculation Formula

Chains Per Hour = (Chain Speed × 3600 × π × Gear Ratio) / (Pitch Diameter × 25.4)

Where:
Chain Speed: Speed of the chain in meters per second
π: Mathematical constant (approximately 3.14159)
Gear Ratio: Ratio of driving gear to driven gear
Pitch Diameter: Diameter of the chain sprocket in millimeters
25.4: Conversion factor from millimeters to inches (1 inch = 25.4 mm)

Chains Per Hour Calculator Usage Guide

Learn how to use the Chains Per Hour Calculator and its working principles for machinery and engineering applications.

How to Use the Calculator

  1. Enter the chain speed in meters per second (m/s). This is typically calculated based on the motor speed and reducer ratio.
  2. Input the pitch diameter of the chain sprocket in millimeters (mm).
  3. Provide the gear ratio between the driving and driven gears.
  4. Click the "Calculate" button to compute the chains per hour.
  5. The result will be displayed in chains per hour (ch/h).

Working Principle

The calculator uses the following formula to determine chains per hour:

Chains Per Hour = (Chain Speed × 3600 × π × Gear Ratio) / (Pitch Diameter × 25.4)

This formula converts the linear speed of the chain (m/s) to a volumetric flow rate (chains per hour) by accounting for the pitch diameter and gear ratio.

Applications

This calculator is useful for:

  • Designing conveyor systems and material handling equipment
  • Calculating chain drive performance in machinery
  • Optimizing production line speeds
  • Engineering applications involving chain drives

Example

For a conveyor system with a chain speed of 0.5 m/s, a sprocket pitch diameter of 100 mm, and a gear ratio of 2:

Chains Per Hour = (0.5 × 3600 × 3.14159 × 2) / (100 × 25.4) = 45.5 ch/h
