The utility model discloses a pulley mounting shell, which comprises an inner shell, which is assembled with a middle shell. The inner shell complements the inner shell cam at the corresponding position between the inner shell and the middle shell. The left and right parts of the inner shell are equipped with pulleys, and the middle part is equipped with anti-slippage devices. The inner shell cam of the inner shell matches with the pulley, and the pulley communicates with the inner shell. The shell is connected with the middle shell through the shell nail, and the middle shell is connected with the middle shell through the shell nail. The middle supporting platform on the shell is tangent to the outer circle of the middle shell nail in the middle of the middle shell. Complementary design of the middle and inner shells, middle shells and inner shells. The inner shells protrude toward both sides of the bearing wheel, and the middle shells cut two vacancy avoidance gaps on each side of the corresponding inner shell position. After assembly, the convex platform of the inner shell is complementary to the vacancy avoidance gap of the middle shell, which has the advantage that the pulley can be loaded into the bearing wheel with larger thickness, and the load-bearing capacity and stability range of the pulley are increased to a greater extent. Degree.
