[0022] The utility model is further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 8As shown, a shaft housing 8 is sleeved on the outer side of the extension shaft 7, one end of the extension shaft 7 passes through the detachable flange 5 and is connected to one end of the coupling 4, the other end of the coupling 4 is connected to one end of the connecting shaft 2, and the other end of the connecting shaft 2 is connected to the temperature box connecting shaft 1; the other end of the extension shaft 7 is connected to the motor connecting shaft 9; a coupling housing 3 is provided on the outer side of the coupling 4.

[0024] The shaft housing 8 is a cylindrical structure, one end of the shaft housing 8 is connected to the fixed flange 8 - 1 , and the other end of the shaft housing 8 is connected to the detachable flange 5 .

[0025] The inner ring of the fixed flange 8 - 1 of the shaft housing 8 is connected to the other end of the extension shaft 7 through a bearing.

[0026] The fixing flange 8 - 1 is a disc-shaped structure, one end of the fixing flange 8 - 1 is fixedly connected to the shaft housing 8 , and the other end of the fixing flange 8 - 1 is connected to the motor connecting frame 10 by bolts.

[0027] The detachable flange 5 is a disc-shaped structure, and a plurality of threaded holes are respectively arranged on the inner and outer rings of the detachable flange 5 . The inner ring of the detachable flange 5 is connected to the shaft housing 8 by bolts, and the outer ring of the detachable flange 5 is connected to the coupling housing 3 by bolts.

[0028] The coupling housing 3 is a "convex"-shaped structure, the upper part of the coupling housing 3 is a cylindrical structure, and the lower part of the coupling housing 3 is a disc-shaped structure; the upper part of the coupling housing 3 is connected to the detachable flange 5 by bolts, and the lower part of the coupling housing 3 is connected to the connecting flange of the temperature box connecting shaft 1 by bolts.

[0029] A plurality of waist-shaped holes are evenly distributed on the outer surface of the cylinder located at the upper part of the coupling housing 3 .

[0030] A gasket 6 is provided between one end of the extension shaft 7 and the detachable flange 5 .

[0031] The structure of the extension shaft 7 of the utility model includes a long shaft whose two ends can be connected to the load motor and the tested motor in the temperature chamber by couplings, and flanges are provided at both ends, the head is a fixed flange 8-1 for fixing the entire extension shaft 7; the tail is a detachable flange 5, and a shaft housing 8 is sleeved on the outer side of the extension shaft 7.

[0032] like Figure 3 As shown, the fixed flange 8-1 is fixedly connected to the motor connecting frame 10 through the fixed mounting hole, and its inner ring is connected to the extension shaft 7 through the bearing. In this way, the entire extension shaft 7 can be well fixed and supported to avoid shaking during the experiment.

[0033] Because the entire extension shaft 7 needs to be placed in the temperature box, but the temperature box opening is small, the extension shaft 7 and the temperature box connecting shaft 1 are designed to be detachable, and the connection part with the extension shaft 7 is also fixed with a mounting hole, which can ensure the connection between the tested motor in the temperature box and the extension shaft 7 to the greatest extent. Figure 4 As shown, due to the detachable structure of the detachable flange 5, the corresponding flange can be replaced at any time according to the tested motor in different temperature chambers, so that the versatility of the extension shaft 7 is improved.

[0034] like Figure 5 As shown, the entire extension shaft 7 is equipped with a shaft housing 8, and the shaft housing 8 and the starting end and the fixed flange 8-1 are directly non-detachable, so that the entire extension shaft 7 can be more stable, avoiding the extension shaft 7 from shaking or unstable connection during the experiment.

[0035] The entire extension shaft 7 is made of aluminum. Due to the material, the entire extension shaft 7 will become lighter, thereby reducing the friction torque, making the test results more accurate, and also making the installation process of the entire extension shaft 7 easier.

[0036] The utility model has been applied and has solved the problem that the test motor needs to be replaced repeatedly in the temperature chamber stand. The detachable flange at the tail makes the test motor mounting flange and the extension shaft part not an integral design, but both are replaceable parts, which greatly reduces the cost of replacing the damaged parts.

[0037] The utility model has the advantages of simple structure, convenient installation, maximum utilization of existing test benches, reduced maintenance costs in the event of damage, ability to test different motors, high versatility, etc.
