[0014] This invention enables the testing device to accurately install gears of various sizes, and after installation, the gear will not exhibit uneven weight distribution during rotation. Specifically, the operation involves first removing the nut and fitting the gear to be tested onto the surface of the mounting rod. Then, the tapered locking block is pressed down using the pressing rod. This downward movement of the tapered locking block allows two positioning blocks to move out of the through groove, thus defining the position of the gear and ensuring that the center of the gear is always aligned with the center of the mounting rod. Once the tapered locking block can no longer be moved down, the nut is then fitted onto the threaded section. Tighten the nut downwards until it completely presses and fixes the gear onto the limit ring. Then, release the pressing rod, which will automatically reset under the action of the second spring. The positioning block will also automatically reset under the action of the third spring. Then, adjust the position of the tube body using the electric slide rail. After adjusting it to be directly above the gear, turn on the drive motor. The drive motor will make the gear rotate. Then, move the impact block upwards using the actuating block. After releasing the actuating block, the actuating block will pop out of the tube body under the action of the first spring and strike the rotating gear, thus completing the impact fatigue test of the gear.
