[0040] The bearing seat support seat 5 is provided on the base 2 , and the bearing seat support seat 5 is connected to the bearing seat 6 of the main shaft 1 and is used to support the bearing seat 6 .

[0041] For details, please refer to the attached Figure 1The base 2 is an annular structure, and a vertically placed main shaft 1 is arranged on its inner circumference. A bearing seat 6 and a bearing seat support foot 4 are arranged on the main shaft, and a connecting seat 3 is arranged between the bearing seat support foot 4 and the base 2. A bearing seat support seat 5 is arranged between the bearing seat 6 and the base 2. The lower end faces of the bearing seat support seat 5 and the connecting seat 3 are connected to the upper surface of the base 2, and the upper end face of the bearing seat support seat 5 is connected to the bearing seat 6 and plays a supporting role. The upper end face of the connecting seat 3 is connected to the bearing seat support foot 4 and plays a supporting role. The arrangement of the connecting seat 3 and the bearing seat support seat 5 can suppress the transportation vibration of the main shaft assembly, reduce the main shaft transportation load and improve the bearing transportation safety. In addition, it should be noted that the vertical transportation of the main shaft assembly reduces the inconvenience of turning during horizontal transportation and the bearing bottom roller is damaged by long-term pressure due to factors such as the gravity of the main shaft assembly, and the main shaft assembly is strictly limited in the vertical and upper and lower directions to prevent damage from vibration during transportation. Similarly, vertical transportation can reduce the transportation footprint, increase the loading capacity of a single vehicle and reduce transportation costs.

[0042] Based on the above embodiment, the connecting base 3 includes a base 301, a bolt 302 and a nut 303. The upper end surface of the base 301 is provided with a threaded hole, the bolt 302 is arranged in the threaded hole, and the nut 303 is threadedly connected to the bolt 302. There are two bolts 302, two nuts 303 and two threaded holes and they are arranged correspondingly.

[0043] Specifically, the upper and lower end faces of the connecting seat 3 are regarded as horizontal planes. The upper end face of the connecting seat 3 is provided with a threaded hole extending in the vertical direction. A bolt 302 is provided in the threaded hole. A nut 303 is provided between the big head end of the bolt 302 and the upper end face of the connecting seat 3. The nut 303 is threadedly connected to the bolt 302. By rotating the nut 303, the length of the bolt 302 extending from the upper end face of the connecting seat 3 can be adjusted. There are two bolts 302 and two nuts 303, and the two bolts 302 both support the lower end face of the bearing seat support foot 4 to ensure that the main shaft assembly is in a vertical state during transportation.

The bolts 302 have a certain length so that they can pass through the horizontal through-holes on the bearing seat support foot 4, and then the bolts 302 are fixed to the bearing seat support foot 4 through the nuts 303. Since the bolts 302 also pass through the through-holes 305, the connection between the vertical plate 304 and the bearing seat support foot 4 can be achieved through the nuts 303 and the bolts 302, which play a lateral limiting and buffering role on the bearing seat support foot 4 as well as a vertical limiting and buffering role, thereby suppressing the transportation vibration of the spindle assembly, reducing the spindle transportation load and improving the transportation safety of the bearing.

[0046] On the basis of the above embodiment, the lower end surface of the connecting base 3 is provided with at least two through holes, the base 2 is provided with a plurality of through holes, and the connecting base 3 is connected to the base 2 by bolts 302 and nuts 303.

[0054] In some embodiments, there are two connecting seats 3 and three bearing seat support seats 5.

[0055] For details, please refer to the attached Figure 1 The two connecting seats 3 and the three bearing seat support seats 5 are evenly distributed on the surface of the base 2, connected to the main shaft assembly and play a supporting and fixing role for the main shaft assembly, thereby suppressing the transportation vibration of the main shaft assembly.

[0056] On the basis of the above embodiment, it further includes a lifting lug tooling 8 , which is provided at one end of the main shaft 1 away from the bearing seat 6 .
