Combination wire wheels, wire wheel structure is to live out of the bearing porcelain bureau. When the silk, the wire in the ceramic circle appearance, the ceramic ring with the wire, the wire rotation, so the sliding friction into a static friction. But in the start and stop, in order to overcome inertia, there will be some sliding friction.
The difference between the use of the wire wheel and the porcelain eye is: when the porcelain eye is used, the wire and the surface are sliding friction, the use of Yu Si, the line angle change is small, the pressure is small, the demand is not high. The main use of the line wheel static friction, the use of Yu Si, the line angle changes, there is a certain positive pressure, higher requirements of the occasion. Recently, with the growth of processing technology, the porcelain eye can also be used for closed occasions, but orders need to be explained.
Porcelain ring surface roughness of RA 0.2, beating during rotation is less than 0.15, material selection of 99 100% Al2O3, hardness HRA 88, density 3.85.
Combination wire wheel: wheel line is divided into line wheel, ceramic wire wheel and anti jumper. Wheel line structure is on the ceramic ring and the bearing along two sides of the two pieces of nylon plate, without side by direct call ceramic wire wheel. Structure anti jumper is on the ceramic ring and the bearing along two sides of the two pieces of ceramic plate, ceramic plate there is a reverse hook or a ball, can avoid the wire, line out of the porcelain above the ring.
