Problems solved by technology
[0003] During the integrated installation process of the planetary car in a narrow operating space, the main shaft assembly connecting the angle adjustment mechanism and the differential mechanism is the basis for the overall assembly of the planetary car body, so the coaxiality of the shaft system of the main shaft assembly of the planetary car is high, but due to The operating space for installing the planetary vehicle is small, and the main shaft assembly connecting the angle adjustment mechanism and the differential mechanism is highly random. Therefore, it is currently difficult to adjust the coaxiality of the shaft system of the main shaft assembly of the planetary vehicle in space, resulting in the current main shaft of the planetary vehicle. The coaxiality of the shaft system of the components is relatively large, so the installation accuracy of the main shaft assembly of the planetary vehicle cannot be guaranteed
