[0001] The utility model mainly relates to the technical field of transmission shafts, in particular to a transmission shaft with a balancing block. Background Art

[0002] The transmission shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The telescopic sleeve can automatically adjust the change in the distance between the transmission and the drive axle. The universal joint ensures the change in the angle between the transmission output shaft and the drive axle input shaft, and realizes the equal angular speed transmission of the two shafts. The transmission shaft is a circular object accessory that can be moved or rotated by connecting or assembling various accessories. It is generally made of light and torsion-resistant alloy steel pipe. For front-engine rear-wheel drive vehicles, the transmission shaft is the shaft that transmits the rotation of the transmission to the main reducer. It can be connected by multiple universal joints. The transmission shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial.

[0003] Existing drive shafts are generally subject to dynamic balancing tests before leaving the factory, and poorly balanced drive shafts are adjusted by welding balancing blocks. However, the high temperature generated by welding the balancing blocks will affect the use of the drive shaft, and the removal and installation of the balancing blocks are relatively troublesome.

[0025] The specific operation process of the present invention is as follows: insert the mounting block 12 into the plug-in slot 3, and then push the mounting block 12 into the mounting slot 9 along the plug-in slot 3. At this time, the sliding block 13 is also pushed into the sliding slot 10, and then the first fixed block 6 is pulled, and the clamping block 5 is rotated from the inside of the rotating slot 4 to the inside of the plug-in slot 3 through the first fixed block 6. At this time, the clamping block 5 is against one side of the mounting block 12, and the mounting block 12 cannot move and is locked, and the first fixed block 6 and the second fixed block 7 are fitted together, and the first fixed block 6 and the second fixed block 7 are fixed by bolts 8, so that the installation of the balancing block body 11 is realized.

[0026] Please refer to Figure 2-Figure 4 The support shaft 2 is provided with an inserting groove 3 and a rotating groove 4, the inserting groove 3 is connected with the rotating groove 4, and a clamping block 5 is slidably connected inside the rotating groove 4.

[0027] The clamping block 5 is retracted inside the rotating groove 4. When the balancing weight body 11 is installed, the clamping block 5 is pulled out from the rotating groove 4 and moved to the plug-in groove 3. In this way, the clamping block 5 can support the mounting block 12 inside the mounting groove 9, and the mounting block 12 cannot move.

[0028] Please refer to Figure 2-Figure 4 The fixing assembly includes a first fixing block 6 and a second fixing block 7. The first fixing block 6 is fixedly installed above the clamping block 5. The second fixing block 7 is fixedly installed on the support shaft 2. The first fixing block 6 and the second fixing block 7 are fitted together, and the first fixing block 6 and the second fixing block 7 are connected together by bolts 8.

[0029] When the clamping block 5 moves from the rotating groove 4 to the plug-in groove 3, the first fixed block 6 moves to fit together with the second fixed block 7, and then the first fixed block 6 and the second fixed block 7 are fixed together by the bolts 8, so that the clamping block 5 is fixed, and the clamping block 5 fixes the mounting block 12.

[0030] Please refer to Figure 2-Figure 5 A mounting groove 9 is provided on the support shaft 2, a sliding groove 10 is provided on the support shaft 2, the mounting groove 9 and the sliding groove 10 are connected, a sliding block 13 is fixedly installed under the balancing block body 11, a mounting block 12 is fixedly installed under the sliding block 13, the mounting block 12 is inserted into the mounting groove 9, and the sliding block 13 is inserted into the sliding groove 10.

[0031] The balancing block body 11 is inserted into the plug-in slot 3 through the mounting block 12, and then the mounting block 12 is pushed into the mounting slot 9. The mounting block 12 drives the sliding block 13 to be pushed into the sliding slot 10, so that the balancing block body 11 is installed on the support shaft 2. The sliding block 13 is used to connect the mounting block 12 and the balancing block body 11, and the sliding slot 10 will limit the sliding block 13 so that the sliding block 13 cannot move. The size of the mounting block 12 is consistent with the size of the mounting slot 9, and the mounting block 12 fits tightly with the mounting slot 9. When the connecting block 5 moves to the inside of the plug-in slot 3, one side of the clamping block 5 will also fit tightly with one side of the mounting block 12, so that the mounting block 12 will be completely locked by the mounting slot 9 and the clamping block 5 and cannot shake. Moreover, since the clamping block 5 is slidably connected to the rotating slot 4, the clamping block 5 will not move left and right. In this way, even if the connection point between the first fixing block 6 and the second fixing block 7 is loosened after being fixed for a long time by the bolt 8, the clamping block 5 will only shake back and forth but not left and right, so that the mounting block 12 can still remain locked.
