PURPOSE: A spherical bearing of a structure is provided to improve abrasion-resistance by improving thermal conductivity generated by friction. CONSTITUTION: A spherical bearing of a structure comprises an upper plate(10), a middle plate(50), a lower plate(90), plating layers(60), and covering layers. The upper plate is formed between upper and lower structures(200,300) and is coupled to the bottom of the upper structure. The middle plate transfers the load of the upper structure to the lower structure, and the bottom of the middle plate is formed in a semi-spherical shape. The lower plate is coupled to the lower structure, and the top of the lower plate is formed in a semi-spherical shape. The plating layers are formed on the bottom of the upper plate and the top of the lower plate. The covering layers are formed on the top and bottom of the middle plate. |
