Embodiment Construction
[0019] Specific embodiments are given below in conjunction with the drawings. An embodiment of the present invention is to test the fatigue life of the steel hole belt under set load conditions. As shown in the figure, install the steel hole belt (8) on the driving wheel (7) and the driven wheel (10) , Turn the adjusting bolt (20), move the track slider (17) to drive the sliding bearing seat (19) to slide until the steel hole belt (8) is in tension, and tighten the adjusting bolt (20) to make the sliding bearing seat ( 19) Fix, turn on the magnetic powder brake (12), adjust the braking force to the set value, turn on the power of the counting sensor (13), and finally turn on the power of the motor (3) to rotate at the set speed, and then drive the steel The hole-making belt (8) rotates, and the counting sensor (13) starts counting until the steel hole-making belt (8) is broken, and the entire test work is completed.

The present invention relates to a device for performing fatigue testing on a steel hole belt, and belongs to the field of mechanical engineering. In order to test the fatigue life of the steel hole belt, the present invention discloses a testing device for a fatigue life of the steel hole belt. The technical scheme is that: a driving wheel end of the steel hole belt is driven by a motor to drivethe steel hole belt to rotate, a magnetic powder brake is used to adjust the load force on the steel belt, and a counting sensor is used to record the number of rotations of the steel belt from the beginning to the fatigue fracture. The testing device for the fatigue life of the steel hole belt has the following advantages that: (1) a position adjustment mechanism can be used to adjust a distancebetween two transmission wheels, and the steel hole belts of different lengths can be tested; (2) the magnetic powder brake can be used to adjust the load force on the steel hole belt, and steel holebelts with different fatigue strength can be effectively simulated for testing; and (3) the structure is simple, the disassembly is convenient, and inspection and maintenance are facilitated.
Description
Technical field [0001] The invention relates to a testing device for the fatigue life of a steel strip, belonging to the field of mechanical engineering, and in particular to a method and equipment for testing the fatigue life of steel hole strips with different fatigue strengths to obtain a steel strip S-N curve. Background technique [0002] At present, most of the research on belt drive stays on leather belts and ordinary steel belts, but there are few researches on steel hole belts. The steel hole belt has the advantages of high manufacturing accuracy, small pitch error, and repeatable meshing between the belt hole and the raised point of the wheel. It is widely used in precision transmission with infinite corners. Correspondingly, the fatigue test for the steel hole belt will provide a reference for its service life in production activities. However, nowadays, the research on the fatigue life of steel hole belts is still at the theoretical stage, and most of them use the an...
