A DEVICE FOR FATIGUE BENDING TESTS

摘要

The device for fatigue bending tests comprises a frame (1) with an electric motor with a drive shaft provided with an eccentric flange (2) and a guide bush (4) for clamping the test piece (3). The guide bush (4) is placed in a cage (9) and a chuck (10) is installed in the guide bush (4) for clamping the test piece (3). A horizontal strap (7) and a vertical strap (8) are attached to the cage (9); they are provided with three-axis force sensors to monitor the load in both loaded axes of movement with the frame (1) of the device. The flange (2) can have an eccentricity of 0.5 to 5mm. The test piece (3) can be keyed for fatigue testing of keyed components.
