The existing testing method is that the ceramic speed reducer is fixed on the test bench through the flange and connected with the torque sensor to monitor its performance. This method provides a very stable mechanical connection because the pre-tightening force of the flange and screw can ensure that the equipment remains stable during testing. However, such a setup may not fully simulate the dynamic characteristics in actual working conditions, for example, the speed reducer on a vehicle may vibrate as the vehicle moves, resulting in a large difference between the existing testing device and its actual working conditions, leading to inaccurate testing.

BRIEF DESCRIPTION OF DRAWINGS

[0013] The utility model makes further explanation to the utility model with the drawings, but the content in the drawings does not constitute any limitation to the utility model.

[0014] Figure 1 It is the whole structure schematic diagram of the utility model. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the utility model is further explained in detail below with the drawings and examples.

[0016] Embodiment 1

[0017] As Figure 1 The utility model discloses a ceramic reducer load test device, which comprises a ceramic reducer, a torsion arm, a screw, a steel sleeve, a load bearing rod, a rubber sleeve, a test base, a deep groove ball bearing, a clamp spring, a connecting shaft, a deep groove ball bearing and a rotary power device.

[0018] Among them, the supporting leg 16 is at the bottom of the test base 7, and the rotary power device 13 is a motor fixed on the top surface right side of the test base 7. The output shaft of the rotary power device 13 is fixedly connected with the connecting shaft 10. The left support frame 14 and the right support frame 15 are fixed in the middle of the test base 7, and the left support frame 14 and the right support frame 15 are rotatably connected with the connecting shaft 10 through the deep groove ball bearing 11 and the clamp spring two 12. The input shaft of the ceramic reducer 1 is connected with the connecting shaft 10 through the spline.

[0019] In this way, the rotating power device 13 drives the ceramic reducer 1 to rotate through the connecting shaft 10. Since the ceramic reducer 1 is only fixed at the right end and the left end is suspended, when the ceramic reducer 1 is driven to rotate by the connecting shaft 10, the pre-tightening force of the left screw is less than that of the existing side view structure in which the bottom is completely fixed on the test base, and the axial shear force is more. In this way, the side view is closer to the use state when it is moving, so that the test made is closer to the actual working condition.

[0020] The connecting shaft 10 is provided with a clamping spring groove on the mounting surface of the connecting shaft and the deep groove ball bearing 11, which is used for installing the clamping spring 9 and the clamping spring 12 to prevent the position of the connecting shaft 10 from being dislocated and the axial movement of the connecting shaft 10.

[0021] The rubber sleeve 6 is sleeved on the steel sleeve 4, and then the bottom end of the torsion arm 2 is fixed on the load rod 5 through the rubber sleeve 6 and the steel sleeve 4. The steel sleeve 4 is used to fix the bottom end of the torsion arm, and the rubber sleeve 6 is used to reduce the influence of resonance generated by the ceramic reducer 1. Finally, the screw 3 on the load rod is locked, so as to realize the support of the entire ceramic reducer 1.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the present application.
