Load Frame: Max Load Capacity 5000 Nm, Weight 45-60 kg

Component Specifications

Definition

The Load Frame is a critical structural component within torque verification units, designed to withstand and distribute precise mechanical loads during torque calibration procedures. It provides a rigid mounting platform for torque sensors, adapters, and test specimens while maintaining dimensional stability under varying load conditions. Engineered for minimal deflection and vibration transmission, it ensures accurate torque measurement by isolating external influences and maintaining consistent alignment between loading mechanisms and measurement devices.

Working Principle

Operates as a passive structural element that transfers applied torque loads from the driving mechanism to the measurement system while maintaining geometric integrity. It functions through rigid body mechanics, where its design minimizes elastic deformation under load to prevent measurement inaccuracies. The frame absorbs and redistributes stress concentrations through optimized cross-sectional geometry and material selection, ensuring uniform load distribution across mounting interfaces.

Materials

High-strength alloy steel (typically ASTM A36 or equivalent), heat-treated to 35-45 HRC hardness; corrosion-resistant coatings (zinc plating or powder coating) for environmental protection; precision-machined mounting surfaces with flatness tolerance ≤0.05mm.

Frequently Asked Questions

What is the primary function of a load frame in torque verification?

To provide a rigid, stable platform that accurately transfers torque loads between driving mechanisms and measurement sensors while minimizing deflection-induced errors.

How does frame stiffness affect torque measurement accuracy?

Higher stiffness reduces elastic deformation under load, preventing angular displacement errors that could cause up to 0.5% measurement deviation in precision applications.
