Revolving fatigue testing machine - has sample-receiving bearings with upper and lower pivoting bearings for applying bending counter-torques transverse to axis of rotation of sample

摘要

Bending occurs at two clamping points in the form of load bearings for the specimen, pivotable centrally transversely wrt. the rotation axis and rotated equally by the force which generates the flexing moment in the specimen. The centrally pivotable load bearings (3.1,3.2) have vertically rotatable side parts (10) at equal distances from the vertical pivot axis in whose axial centre are arranged the support bearings for the specimen (1). USE/ADVANTAGE - For measuring bending fatigue strength of rotating round specimens. Horizontal load direction and constant bending moment over length of at least 200 mm. are achieved.
