[0066] As a preferred solution of this embodiment, Figure 6 As shown, the diaphragm coupling 2020102 is provided with a motor-to-coupling transition piece 2020115. The diaphragm coupling 2020102 is coaxially connected to the rotor 2020103 with a speed torque meter via a coupling-to-torque meter transition piece 2020116. The output flange 2020106 is connected to the transmission-end primary shaft spline sleeve 2020107 via a transmission-end flange-to-primary shaft spline sleeve transition piece 2020117. The motor-to-coupling transition piece 2020115, the coupling-to-torque meter transition piece 2020116, and the transmission-end flange-to-primary shaft spline sleeve transition piece 2020117 all employ known transition pieces.

[0068] As a preferred solution of this embodiment, Figure 6 As shown, an end cover 2020119 is provided on the output flange 2020106.

[0069] In this embodiment, the components used are all known and commonly used components. The component drawings of the main components are as follows: Figures 8 to 24 shown.

[0070] In this embodiment, a grease filling hole and a bearing temperature sensor are also arranged on the intermediate bearing seat 2, so as to perform maintenance and monitoring on the bearing.

[0071] In this embodiment, the diaphragm coupling 2020102 has the functions of correcting deviation and protecting.

[0072] When the test bench of this embodiment is in use, the new energy product motor 1 is powered, the intermediate bearing seat 2 and the transmission assembly 3 are powered, and the loading motor 4 is powered, forming a complete power closed loop. Compared with the traditional testing method, the utility model innovatively adds an intermediate bearing seat 2 between the new energy product motor 1 and the transmission assembly 3, thereby realizing real-time measurement of the output speed and output torque of the new energy product motor 1, which is also the input speed and input torque of the transmission assembly 3.

[0073] The specific transmission method of the rotating parts in the intermediate transmission sub-assembly 20201 of this embodiment is as follows: after the outer casing of the new energy product motor 1 is fixedly connected to the product motor end transition piece 20204 by bolts, the inner spline rotor of the new energy product motor 1 cooperates with the new energy motor end transition spline 2020101; the outer casing of the transmission assembly 3 is fixed to the transmission end transition piece 20205, and the one-shaft spline of the transmission assembly 3 cooperates with the one-shaft spline sleeve 2020107 at the transmission end, thereby realizing complete power transmission.

The locking pin 2020108 cooperates with the pin hole to lock the rotor of the intermediate bearing seat 2, thereby performing a locking test. A plurality of evenly distributed pin holes are provided to meet the requirements of different angles of the locking test; at the same time, it can also meet the requirements of locking the rotor when calibrating the torque meter of the intermediate bearing seat 2.

[0075] The test bench in this embodiment can also be used with an environmental chamber that encloses the new energy product motor 1 and transmission assembly 3 to perform high and low temperature testing on these products. In this embodiment, the environmental chamber is an external temperature-controlled box that controls the environment of the product motor to meet the requirements of high and low temperature testing. Specifically, the product motor is enclosed in the environmental chamber, which is connected to a heating and cooling unit for cooling or heating.

[0076] In this embodiment, when performing calibration testing on the new energy product motor 1, the real-time output speed and output torque of the new energy product motor 1 are measured through the battery simulator power data and the power analyzer on the circuit, combined with the intermediate bearing seat 2, so that calibration testing of various parameters of the new energy product motor 1 can be realized.

[0077] In this embodiment, when testing the transmission assembly 3, a new energy product motor with higher power is selected as the loading motor 4 to drive the transmission assembly 3, so that the transmission assembly 3 can be tested at peak power for a long time, shortening the test cycle.

[0078] In this embodiment, when the new energy product motor 1 and the matching transmission assembly 3 are tested, the output speed and output torque of the new energy product motor 1 can be measured in real time, which are also the input speed and input torque of the transmission assembly 3.

[0079] In this embodiment, to replace different new energy product motors 1 and transmission assemblies 3, it is only necessary to replace the product motor-end transition piece 20204, the transmission-end transition piece 20205, the transmission-end single-shaft spline sleeve 2020107 and the new energy motor-end transition spline 2020101 with the corresponding products for testing, which can meet the testing needs of multiple products and multiple models of new energy product motors with transmission assemblies.

[0080] In this embodiment, for the new energy product motor 1 with a single-shaft external spline output, the transition spline 2020101 at the new energy motor end can also be replaced with a corresponding matching internal spline transition to carry out product testing.
