Description

Technical Field

[0002] At present, the horizontal anchoring equipment on the market mostly uses bolts, cylindrical pins or a combination of bolts and cylindrical pins to connect the anchor chain wheel and the gear. The power source is decelerated by the gear pair to drive the gear to rotate, thereby driving the anchor chain wheel to rotate. However, in the actual working process, due to the vibration of the anchoring equipment itself and the impact of the anchor chain on it, the fasteners between the anchor chain wheel and the gear will gradually loosen, which seriously affects the function of the equipment. In this regard, after improvement, the bolts and cylindrical pins were welded together by spot welding. However, after feedback after use, the fasteners between the anchor chain wheel and the gear still became loose, and because the equipment has been in the marine salt spray environment for a long time, friction and collision often occur between the anchor chain wheel and the anchor chain, making the electric welding point very easy to rust, which seriously affects the disassembly and assembly of the anchor chain wheel or the gear, and is not convenient for later maintenance.
