The Rotating Cantilever Fatigue testing machine is intended for determining the fatigue strength under reversedbending stresses. It is suitable to determine the fatigue life and location of fatigue failure of metals specimens subjected to alternating stress cycles. The high operating speeds of modern machine and the extreme stress ranges to which the material of construction is subjected, make fatigue testing a necessity.
Fatigue testing of materials in an important prerequisite for theconstruction of structual componants like aircraft parts, axles,crank shafts, connecting rods, springs, pinion teeth, floor beams of bridges which are subjected to cyclist stresses; and hence the importance of fatigue test,by industries engaged on machine design or manufacturers of such componants or parts,is most essentials.
The Fatigue Testing Machine Machine helps in determining the fact as to how much strong the specimen is against bending where it has to bear a continuous rotating stress. The machine is supported as a contilever and loaded by dead weights applied at the free end through self aligning bearings which permit both vertical loading and the rotation of the specimen A counter balancing lever system is used to balance the dead weight of the loading assembly. The specimen is rotated by an induction motor. A cut-out switch is provided to stop the machine when the specimen fails. To record the total number of cycles to failure, a counter is fitted to an extension of the motor shaft through a reduction gear.Specimen … ….. 1/2" diam x 5" longSpeed …. … ….. 2850 r.p.m.Motor ….. ….. ….. 0.5 H.P. 440 volts 50 c/s, 3 phase AC.Counter … ….
