Furthermore, threaded holes are formed in two sides of the lower end of the base.
Furthermore, two ends of the annular mounting hole are provided with annular bosses, and the steel ball outer ring is mounted on the annular bosses.
Furthermore, the end face of each rotating body is provided with a connecting hole, a flywheel is installed on the connecting hole, the circumferential edge of the flywheel extends to the base, and the flywheel at the two ends and the base form a closed space.
According to the invention, the rotating body is further externally connected with the flywheel, and because the mass of the flywheel is larger than that of the rotating body, the flywheel transmits force to the central shaft at high-speed rotation and deceleration, and the torsion generated by the central shaft is larger, so that the load capacity of the central shaft is improved.

Meanwhile, in order to increase the load capacity of the central shaft, the rotating body is externally connected with the flywheel, and the mass of the flywheel is larger than that of the rotating body, so that the inertia generated in high-speed rotation is larger, and the load capacity of the central shaft is further increased.
