In specific implementation, one ends of the two transmission shafts 21, which are far away from the middle position of the support 10, are respectively connected with the dynamometer and the engine, and the transmission shafts 21 and the adapter flange 22, the mounting flange 22 and the belt wheel 23 are in interference fit or over fit, so that the connection and the fastening between the transmission shafts 21 and the adapter flange 22 and between the mounting flange 22 and the belt wheel 23 can be ensured; the two belt wheels 23 forming the belt transmission have the same diameter, so that the transmission ratio is 1:1, and the originality of test data is ensured.
Further, the transmission mechanism 20 further includes a bearing 25 with a seat for fixing the transmission shaft 21, the bearing 25 with a seat is fixed on a bearing mounting plate 26, and the bearing mounting plate 26 is connected with the support 10 below the bearing mounting plate 26. During specific implementation, the self-aligning bearing with the seat can be selected for the bearing with the seat 25 to ensure the coaxiality of the bearings at the two ends, and the bearing is prevented from being influenced by installation errors.
Further, the support 10 includes a bottom plate 11, the bottom plate 11 is provided with two diagonally arranged sinking platform portions 112, and the sinking platform portions 112 are connected with the bearing mounting plate 26. The position between the two transmission shafts 21 can be adjusted by fixing the pedestal bearing 25 on the sinking platform part 112 of the bottom plate 11 through the bearing mounting plate 26, so as to facilitate the installation and tensioning of the belt 24.
Preferably, a strip-shaped hole 111 is formed in the middle of the bottom plate 11, and part of the wheel body of the pulley 23 is placed in the strip-shaped hole 111. Such an arrangement makes efficient use of the space of the support 10, making the overall structure more compact and reasonable.
