The main machine structure comprises a rotor, a machine shell, an upper bearing support, an upper bearing pair, an upper bearing gland, a machine base, a lower bearing support, a lower bearing gland, a lower bearing pair and a bearing lantern ring provided with a dustproof hole. The upper bearing support is provided with an installation hole and fixedly connected to the upper end of the machine shell. The upper bearing pair is fixedly connected to the interior of the installation hole through the upper bearing gland. The lower bearing support is fixedly connected to the machine base. The machine base is fixedly connected to the lower end of the machine shell. The bearing lantern ring is fixedly connected to the lower bearing support. The lower bearing pair is fixedly connected to the interior of the dustproof hole in the bearing lantern ring through the lower bearing gland. The upper end and the lower end of the rotor are supported in the upper bearing pair and the lower bearing pair respectively. The upper tail end and the lower tail end of the rotor extend out of the machine shell through the upper installation hole and the dustproof hole. A first dustproof groove is formed in the inner wall of the installation hole. A second dustproof groove is formed in the inner wall of the dustproof hole. A third dustproof groove is formed in the inner hole wall of the lower bearing gland.
