DETAILED DESCRIPTION

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 , Figure 3As shown, the chain fatigue test bench comprises a bottom plate 1, a top plate 2 and a shell 3 distributed between the bottom plate 1 and the top plate 2. A fixing plate 4 is further provided between the bottom plate 1 and the top plate 2, and a tooling plate 1 5 and a tooling plate 2 6 are provided at the front of the fixing plate 4, and a sprocket 7 is provided on the tooling plate 1 5 and the tooling plate 2 6, and the two sprockets 7 are connected by a chain 8. A driving device 9 for driving the sprocket 7 on the tooling plate 2 6 to rotate is provided on the bottom plate 1, and a sprocket 9 for driving the sprocket 7 on the tooling plate 2 6 to rotate is provided at a position corresponding to the tooling plate 1 5 in the shell 3. 5, the rotary shaft 10 is a passive shaft. After the driving device 9 drives the corresponding sprocket 7 to transmit, the chain 8 transmits, and the rotary shaft 10 plays a passive guiding role, so that the sprocket 7 located at the upper part transmits, and the transmission phenomenon of the chain 8 when the engine is in working state is simulated as a whole. A mounting seat 11 is provided on the top of the top plate 2, and a spring 12 with adjustable tension is provided on the mounting seat 11. A sensor 13 for measuring the tension of the spring 12 is provided between the mounting seat 11 and the top plate 2, and a positioning mechanism is also provided on the housing 3.

[0015] To elaborate further, an installation box 14 for installation is provided at the rear of the rotating shaft 10, an adjustment plate 15 for installation of the installation box 14 is provided between the top plate 2 and the bottom plate 1, a connecting plate 16 for connecting the sensor 13 is provided on the top of the installation box 14, a plurality of guide columns 17 are provided between the top plate 2 and the bottom plate 1, and the adjustment plate 15 is installed on the corresponding guide columns 17 through a plurality of adjustment seats 18. After the corresponding position of the adjustment plate 15 is adjusted, the tension of the spring 12 is adjusted, and the tension of the spring 12 is sensed by the sensor 13. Therefore, after the adjustment plate 15 is adjusted into place, the tooling disk 5 is also adjusted accordingly, so the tension of the corresponding chain 8 is adjusted.

[0016] In further detail, a display screen 19 is provided on the bottom plate 1 outside the housing 3, and the display screen 19 feeds back a number of data, such as the tension of the spring 12, the amount of wear, the transmission time of the chain 8, and the width or thickness of the chain 8 in the initial state.

[0017] By simulating the transmission of the engine chain 8, simulating the tension on the engine chain 8, and the corresponding transmission time of the engine chain 8, the amount of wear of the chain 8 during this period is measured, and then it is calculated how long the chain 8 can last. In simple terms, if the chain 8 transmits for one day, the force is worn away by 0.01 per day, and the chain itself has a thickness of 1, then the chain 8 can work for 100 days.

[0018] To further explain, the positioning mechanism includes a fixed block 20, an adjusting block 21 and a roller 22 for the chain 8 to pass through. A clamping block 23 for installing the roller 22 is provided at the rear end thereof, and an adjusting rod 24 is provided at the rear end of the clamping block 23. The adjusting rod 24 is provided with a plurality of adjusting holes 25. The clamping block 23 is fixed to the corresponding adjusting holes 25 by a fixing member, so that the position of the roller 22 can be adjusted, and the pressing position of the roller 22 can be adjusted according to the thickness of the chain 8. The adjusting block 21 is connected to the fixed block 20 through a screw 26. The adjusting block 21 has an opening 27. A connecting portion 28 connected to the adjusting rod 24 is provided in the adjusting block 21. A slot 29 is provided on the connecting portion 28. The position of the screw 26 can be adjusted to adjust the position of the adjusting block 21, and then the pressing force of the roller 22 on the chain 8 can be adjusted. Adjusting the pressing position and pressing force of the roller 22 can further effectively guide the chain 8 to meet the testing of chains 8 of different specifications.
