The present disclosure relates to a winding drum (1) assembly. The winding drum (1) used for winding a safety belt extends in the axial direction and is rotatably supported in a frame of a retractor. A gear mechanism (2) is installed at one side of the winding drum (1) through a force limiting mechanism (3) and comprises a stop wheel (21) and a ball gear (22) which are riveted and fixedly connected in the axial direction. The stop wheel (21) is rotatably installed on the frame, and the ball gear (22) comprises a penetrating shaft hole (221A). The force limiting mechanism (3) is inserted into the shaft hole (221A) in the axial direction and both ends of the force limiting mechanism (3) are respectively connected with the winding drum (1) and the gear mechanism (2) to prevent passengers from being excessively restrained by realizing the force limiting function. According to the winding drum (1) assembly of the present disclosure, the gear mechanism (2) and the force limiting mechanism (3) are directly assembled to the winding drum (1), with simple steps and few independent components. In addition, the force limiting mechanism (3) is inserted into the shaft hole (221A) of the ball gear (22) in the axial direction to make the force limiting mechanism (3) and the gear mechanism (2) overlap in a larger part in the axial direction, so that the size of the whole winding drum (1) assembly can be smaller.
