[0002] Cage winches are used for winding or cabling copper wire, aluminum wire, small-diameter plastic-insulated cables and rubber-sheathed cables, long-distance symmetrical plastic cables, and multi-strand nylon ropes. During operation, the exposed lengths at the front and rear winches are unequal; the rear section is shorter, and this end is mainly equipped with the transmission system and un-twist mechanism. The front section is longer and has a detachable wire divider plate at the shaft end, allowing for a smooth wire release angle.

[0003] To prevent the conductors stranded or cabled on a cage winch from being scratched, a guide wheel device is usually installed at the conductor outlet of the winch reel. This ensures a smoother release angle between the separator plate and the conductor outlet. The guide wheel shaft, equipped with the guide wheel, is securely fixed to a suitable bracket welded to the conductor outlet of the winch reel. The guide wheel and shaft are connected by bearings. After a period of use, bearing damage or wear on the guide wheel groove surface can occur, scratching the stranded or cabled conductors. Bearing damage can also cause the dimensions of the guide wheel shaft and bearing mating section to mismatch with the bearing's installation requirements. Replacing the guide wheel requires replacing the guide wheel shaft as well, reducing the efficiency of guide wheel replacement. Utility Model Content
