According to the independent variable-pitch method of the wind driven generator with the good lubricating performance, a variable-pitch motor is used for driving a small gear, so that a large gear driving meshing drives a bearing inner ring to rotate, then wind driven generator blades connected to the outer side of the bearing inner ring are driven, and the bearing inner ring is fixedly connected with the roots of the blades of the wind driven generator through bolt holes and bolts; independent variable pitch of the wind driven generator is realized; the miniature air pump is utilized to inflate and pressurize the air bag, so that the volume of the air bag in the lubricating ball is increased, and then internal lubricating oil is discharged from the discharge hole and the connecting pipe, enters the circulation cavity through the connecting hole and then enters a rotating gap between the bearing outer ring and the bearing inner ring through the seepage hole, so that lubrication and cooling are realized; there
