Calibration Dial/Screw: Torque Capacity 5-50 Nm

Component Specifications

Definition

A precision mechanical component consisting of a calibrated dial and fine-threaded screw assembly designed for micro-adjustment of force or tension in industrial machinery. This component enables operators to make controlled, repeatable adjustments to force application systems with high accuracy, typically featuring graduated markings for visual reference and locking mechanisms to maintain settings.

Working Principle

The calibration dial/screw operates on the principle of mechanical advantage through fine-pitch threading. Rotating the dial advances or retracts the screw along its axis, converting rotational motion into precise linear displacement. This displacement directly affects the force application mechanism, allowing for controlled adjustment of tension, pressure, or load. The graduated dial provides visual feedback for repeatable settings, while locking mechanisms prevent unintended movement during operation.

Materials

High-strength alloy steel (typically AISI 4140 or equivalent), stainless steel (304 or 316 grade for corrosion resistance), or hardened tool steel with surface treatments including black oxide coating, zinc plating, or chromium plating for durability and wear resistance

Frequently Asked Questions

What is the typical accuracy range for calibration dials/screws?

High-quality calibration dials/screws typically offer accuracy within ±0.02mm per full rotation, with some precision models achieving ±0.01mm. The actual accuracy depends on thread pitch, manufacturing tolerances, and dial graduation quality.

How often should calibration dials/screws be maintained?

Regular inspection every 6 months is recommended, with lubrication every 3-6 months depending on usage frequency. Complete calibration verification should be performed annually or after 10,000 adjustment cycles, whichever comes first.

Can calibration dials/screws be used in high-vibration environments?

Yes, but they require locking mechanisms or thread-locking compounds to prevent unintended movement. Special vibration-resistant designs with finer threads and positive locking features are recommended for high-vibration applications.
