The invention provides a lifting apparatus for a rear main bearing of a wind-driven generator unit and belongs to the technical field of wind-driven generator units. The lifting apparatus comprises a circular plate, and at least four lifting plates, at least three limit plates and at least three matching plates, which are arranged on the same side of the circular plate, wherein the lifting plates are uniformly fixed to the circular plate in the circumference radial direction and carry out lifting through the cooperation of shackles, lifting rings, lifting chains or crane lifting hooks; the limit plates are uniformly fixed to the circular plate in the circumference radial direction, and the outer diameter of a circle formed by the limit plates is smaller than the inner diameter of an inner ring of the bearing to be lifted; and the matching plates are uniformly connected to the circumference of the circular plate through bolts and support the inner ring and an outer ring of the bearing. Through optimizing the structure of the lifting apparatus, the relative sliding problem of the inner and outer rings of a self-aligning bearing in the mounting process is solved, and the bearing is convenient to unload after being lifted. Under the condition of ensuring lifting apparatus strength and fatigue, unit mounting reliability and production efficiency are improved, the service life of the unit is also indirectly prolonged, and enterprise benefit is increased.
