2. Product structure of crown wheel and guide wheel, castings and forgings

There are basically two kinds of roof wheel & guide wheel structure: one is the spoke structure, the other is the welding structure. The former is the old structure, the overall rigidity is poor, spokes are easy to break in use. Rope groove liner is hardwood material, easy to wear, frequent replacement, and noise in operation. The inner diameter of the swimming wheel is inset with bearing bush, and the rotating mating surface is lubricated by grease in the oil cup. After a certain period of use, the grease will deteriorate and dry up, and the oil passage will be blocked, which is not conducive to lubrication again. The bearing bush is made of cast iron, which is easy to wear and fracture, and the maintenance workload is large.

The welded type is improved in structure to improve the overall strength, wear-resistant engineering plastics are used for the lining of the rope groove to prolong the service life, high-quality brass materials are used for the bearing bush, thin oil is used for lubrication, and the oil cup is moved to the outer circular side of the swimming wheel to facilitate the daily oil filling operation.
