The utility model discloses a hub of a wind turbine generator. The hub is manufactured by adopting a 3D printing technology. The hub is a spherical hub, the spherical hub comprises a spherical shell,the shell comprises a main shaft mounting hole and a variable-pitch bearing mounting hole, a hub web at the variable-pitch bearing mounting hole comprises an outer ring part and a middle part, the outer ring part is provided with a plurality of uniformly distributed bolt mounting process holes, and the middle part is of a grid-shaped structure. And the grid-shaped structure is printed by adoptinga high-rigidity material. And the shell is also provided with heat dissipation ventilation holes. And areas around the heat dissipation ventilation holes are printed by adopting a high-strength material. The wind power hub is manufactured based on the 3D printing technology, the structure of the hub can be optimized as much as possible, the weight of the hub is reduced, the size of the hub is reduced, and transportation, h
