Description

Technical Field

[0001] The utility model relates to the technical field of coupling oil seal disassembly tools, in particular to an auxiliary tool for installing a coupling oil seal. Background Art

[0002] Installing the oil seal on the coupling usually requires certain skills and appropriate tools to ensure that the oil seal is installed correctly and can effectively seal to prevent oil leakage and protect the equipment from contamination. Here are some basic steps and precautions:

[0003] 1. Preparation: Ensure the working environment is clean to prevent dust and other impurities from entering the oil seal or bearing; select a suitable oil seal and confirm that its size and material (such as rubber, polyurethane, etc.) match the coupling and the use environment; prepare necessary tools, which may include special oil seal pressing tools, cleaners, lubricants, etc.

[0004] 2. Cleaning and inspection: Thoroughly clean the coupling shaft journal and oil seal mounting surface to remove any dirt, rust or old seal residue; check the shaft journal for scratches, dents or irregular shapes, repair if necessary, and ensure a smooth surface.

[0005] 3. Lubrication: Use the recommended lubricating oil or grease to lightly apply on the oil seal lip and journal surface. This will help the oil seal to be installed smoothly and reduce wear during initial startup.

[0006] 4. Install the oil seal: Use a rubber hammer or other tool to slowly and evenly push the oil seal into place. For oil seals with a taper, ensure that the oil seal expands gradually during installation while preventing the lip from rolling up.

[0007] 5. Check the installation quality: After installation, check whether the oil seal is fully fitted without distortion or damage; confirm that there is no gap in the sealing interface between the oil seal and the shaft neck and coupling housing.

[0008] 6. Subsequent treatment: For occasions where necessary, add sealant or use other sealing enhancement measures according to the manufacturer's recommendations; finally, fill with lubricating oil or other media as needed and check for leaks.

[0009] During the installation of the oil seal on the main hook coupling of the overhead crane, two people are required to cooperate, one person carries the coupling and the other installs the oil seal. The entire installation process is completed manually. Since the coupling is heavy and the oil seal needs to be installed with high precision, it needs to be adjusted several times during the installation process with a rubber hammer. If the two people do not cooperate well and the safety confirmation is not in place, the coupling may fall over, which may damage the spare parts and cause safety hazards such as injuries.

[0010] Therefore, there is an urgent need to design an auxiliary tool for installing the coupling oil seal to solve the problems of low manual operation efficiency, easy damage of spare parts and potential safety hazards in the existing coupling oil seal installation. Utility Model Content

[0013] Specifically, the arc-shaped bracket adopts a semicircular arc, and two arc-shaped brackets are arranged opposite to each other and clamped on the outer side of the lower column of the upper mounting seat of the coupling.

[0014] Specifically, the coupling comprises an upper mounting seat, a lower mounting seat and a main shaft, and an oil seal ring assembly is installed on the upper cylinder of the lower mounting seat.

[0015] Specifically, the relative diameter of the semicircular arc of the arc bracket is larger than the diameter of the lower column of the upper mounting seat of the coupling, the inner side of the arc bracket is tightly attached to the outer side of the lower column of the upper mounting seat of the coupling, and the upper part of the arc bracket is supported on the bottom of the flange of the upper mounting seat.
