DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will describe in detail a specific embodiment of the present utility model in conjunction with the accompanying drawings. However, it should be understood that the protection scope of the present utility model is not limited by the specific embodiment.

[0026] As Figures 1 to 2 shown, a reducer test bench provided by an embodiment of the present utility model includes a test platform 1, a reducer test assembly, a reducer oil injection assembly, and a fuel tank 6 provided on the test platform 1;

[0027] Among them, the reducer oil injection assembly includes an oil pump 2, an oil pump motor 3, a suction pipe 4, and an injection pipe 5. The suction pipe 4 and the injection pipe 5 are connected to the oil pump. The suction port of the suction pipe 4 is located in the fuel tank 6, and a filter screen 7 is installed at the suction port to play a certain filtering role and reduce damage to the oil pump.

[0028] The oil injection assembly of this embodiment uses an oil pump for oil supply, which is safer and more reliable than the method of lifting the fuel tank 6 in the prior art for refueling.

[0029] The reducer test assembly includes an adjustment bracket and a reduction motor 8, a screw 9 and a belt pulley 10 mounted on the adjustment bracket. It also includes a starting motor 11 for driving the belt pulley 10 to rotate. The belt pulley 10 is transmission-connected to the input end of the reducer to be tested. The reduction motor 8 is used to drive the screw 9 to rotate. The height of the belt pulley 10 is adjusted by rotating the screw 9. This is an existing structure and will not be described in detail here.

[0030] To achieve oil recycling, the test platform 1 is provided with an oil recovery circuit 12, which is connected to the oil tank 6. To prevent the reused oil from being contaminated, the oil tank 6 of this embodiment is provided with multiple filtering structures. To prevent iron slag and granular impurities inside the tested reducer from being injected into the reducer to be tested through the recycled oil, at least one of the multiple filtering structures of this embodiment is installed with a permanent magnet 14.

[0031] Specifically, the plurality of filter structures include a filter structure 13 and at least one filter structure 2 15. The filter structure 13 is provided with a filter screen, and the filter screen is provided with a plurality of permanent magnets 14. The filter structure 2 15 is provided on the lower side of the filter structure 13. The filter structure 2 15 is provided with filter paper. The filter paper can further filter some impurities on the basis of the filter screen.

[0032] The number of the second filter structure 15 in this embodiment is one, which can be fixed in the oil tank 6;

[0033] In addition, in order to further improve the adsorption effect of some metal impurities, the filter screen of the filter structure 13 can adopt an arc structure, that is, it is high in the middle and low on the periphery, and there is no filter hole in the middle position, and filter holes are provided on the periphery. The permanent magnet 14 is also provided on the periphery, thereby extending the residence time of the oil in the filter structure 13 and improving the impurity removal effect.

[0034] To facilitate replacement of the filter paper, the filter structure 13 is detachably mounted at the inlet of the fuel tank 6. Therefore, the filter can be cleaned by removing the filter structure 13. Furthermore, the filter paper of the filter structure 2 15 can also be replaced.

[0035] The detachable method can adopt a magnetic structure;

[0036] The three-stage filtering structure, comprising filtering structure 13, filtering structure 2 15 and the filter screen 7 at the oil suction port, ensures the quality of the oil and prevents impurities from entering the reducer to be tested, thereby ensuring the accuracy of the test data.
