Lead Screw Distance Formula:
| From: | To: |
The distance per revolution of a lead screw refers to the linear distance traveled by the nut or load for each complete rotation of the screw. It is equal to the lead of the screw, which is the axial distance the screw moves in one complete turn.
The calculator uses the simple formula:
Where:
Explanation: The distance traveled per revolution is directly equal to the lead of the screw. This relationship is fundamental to lead screw mechanics and motion control systems.
Details: Accurate distance calculation is crucial for precision positioning systems, CNC machines, 3D printers, and other mechanical systems that use lead screws for linear motion conversion.
Tips: Enter the lead value in meters. The lead is typically specified by the manufacturer and represents the linear travel distance per complete revolution of the screw.
Q1: What is the difference between lead and pitch?
A: Pitch is the distance between screw threads, while lead is the distance the screw advances in one complete revolution. For single-start screws, lead equals pitch.
Q2: How does multi-start threading affect distance calculation?
A: For multi-start screws, the lead is equal to the pitch multiplied by the number of starts. The distance per revolution calculation remains the same.
Q3: What units should I use for lead measurement?
A: While meters are used in this calculator, lead is often specified in millimeters (mm) in engineering applications. Convert to meters by dividing by 1000.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise. However, actual mechanical performance may be affected by factors such as backlash, wear, and manufacturing tolerances.
Q5: Can this calculator be used for ball screws?
A: Yes, the same principle applies to ball screws. The distance per revolution is equal to the lead of the ball screw.
