[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] Example 1:

[0028] like Figures 1-4 As shown, the gear transmission shaft structure provided by this utility model includes: two mating shaft parts 1 and a bushing 2. Gears are installed on the mating shaft parts 1, and a universal joint 3 is installed at one end of the two mating shaft parts 1 that is close to each other. The universal joint 3 enables the two mating shaft parts 1 to be used in a non-aligned state. Figure 3 As shown), there is a certain angle between the two mating shaft parts 1. Figure 3 The included angle is 30 degrees. When the bushing 2 is simultaneously fixed on the two mating shaft parts 1, the two mating shaft parts 1 are axially aligned and connected as a whole for use. Figure 2 (as shown), or as Figure 1 or Figure 3 As shown, the bushing 12 is fixed to one of the mating shaft parts 1, allowing the two mating shaft parts 1 to be movably connected. Gears can be installed on the two mating shaft parts 1 for gear transmission, such as... Figure 3 As shown, the two mating shafts 1 are used at a certain angle, which can change the direction of gear transmission while transmitting power. This is suitable for gear transmissions that need to avoid certain positions, thus making the gear transmission forms more diverse.

[0029] By setting two docking shaft parts 1 and bushing 2, and using a universal joint 3 to connect the two docking shaft parts 1, the two docking shaft parts 1 can be used at a certain angle, which allows the transmission shaft to be converted into various forms, making the gear transmission form more diversified and suitable for various occasions.

[0030] Example 2:

[0031] like Figures 1-3 As shown, in order to fix the bushing 2, two bolts 5 are threaded on the bushing 2. When in use, rotate the bolts 5 so that one end of them presses tightly against the mating shaft 1, and the bushing 2 can be fixed on the mating shaft 1.

[0032] The bushing 2 can be easily fixed by threading bolts 5 onto the bushing 2.

[0033] Example 3:

[0034] like Figures 1-4As shown, in order to prevent the bushing 2 from moving axially, a positioning groove 4 is provided on the mating shaft 1. The positioning groove 4 is adapted to the diameter of the bolt 5. When in use, the end of the bolt 5 is screwed into the positioning groove 4 to prevent the bushing 2 from moving axially.

[0035] By opening a positioning groove 4 on the mating shaft 1, the bushing 2 can be prevented from moving axially on the mating shaft 1, thereby improving the stability of the bushing 2 in use.

[0036] Example 4:

[0037] like Figure 1 As shown, a gear mounting position 6 and a bearing mounting position 7 are provided on the mating shaft 1. In use, the gear is fixed in the gear mounting position 6, while the bearing is fixed in the bearing mounting position 7. The mating shaft 1 is then fixed to the equipment by the bearing. It is worth noting that the positions of the gear mounting position 6 and the bearing mounting position 7 can be interchanged, and their dimensional ratios must be adjusted accordingly to suit different applications.

[0038] By setting gear mounting position 6 and bearing mounting position 7, the installation of bearings and gears can be facilitated.

[0039] Example 5:

[0040] like Figures 1-4 As shown, an external thread 8 is provided on the mating shaft 1. Nuts and washers can be installed at the external thread 8 to fix the outside of the bearing and improve the stability of the bearing and the mating shaft 1.

[0041] By creating an external thread 8 on the mating shaft 1, the bearing can be easily fixed from the outside, improving the stability of the bearing and the mating shaft 1.

[0042] Example 6:

[0043] like Figures 3-4 As shown, a keyway 9 is provided on the gear mounting position 6. In use, a key bar is installed in the keyway 9, and the key bar is installed on the gear mounting position 6 with the groove in the center hole of the gear aligned with it, which can prevent the gear from slipping and rotating on the gear mounting position 6.

[0044] By creating a keyway 9 in the gear mounting position 6, a key bar can be easily installed, thereby limiting the position of the gear.

[0045] Working principle: When in use, (1) when the bushing 2 is fixedly sleeved on the two mating shaft parts 1 at the same time, the two mating shaft parts 1 are axially aligned and connected as a whole.

[0046] (2) the shaft sleeve 12 is fixed on one of the two butt shafts 1, so that the two butt shafts 1 are movably connected through the universal shaft 3, and gears can be respectively installed on the two butt shafts 1 for gear transmission. Especially when the two butt shafts 1 are used at a certain angle, the gear transmission direction can be changed while power transmission is performed, so that the gear transmission form is more diversified, and can be suitable for use in different occasions.
