Axial-Torsion Wedge Grips
The application of both axial and torsional forces simultaneously under fatigue conditions requires special grip design. These grips utilize a wedge-action gripping technique making them suitable for flat specimens as well as cylindrical.
Principle Of Operation
The major grip components are the grip driver, wedge grip head, grip attachment flange and jaw faces.
The grip driver applies the clamping force to the grip head by moving it relative to the jaw faces.This causes the the jaw faces to clamping the specimen.
The grip drive also incorporates 3 sets of anti-rotation sliders that transfer any applied torque from the actuator to the grip and specimen. The jaw faces are either serrated or V-grooved to accommodate flat or cylindrical specimens.
Application Range
- Axial/Torsion tests on flat or cylindrical specimens
