Combination wire wheels, wire wheel structure is to live out of the bearing porcelain bureau. When the wire, the ceramic ring appearance came, with silk, porcelain ring line rotation, so the sliding friction is changed into static friction. But at the start and stop, in order to overcome the inertia, there will be a part of sliding friction.
The difference between the line wheel and the use of the porcelain eye: the porcelain eye use wire, and the appearance is sliding friction, with Yu Si, line angle changes little, positive pressure is smaller, less demanding situations. The use of static friction to the line wheel, with Yu Si, line angle changes, a certain pressure and high requirement. Recently, with the growth of processing technology, the porcelain eye can also be used for closed occasions, but orders need to be explained.
The surface roughness of porcelain ring Ra 0.2, beating during rotation is less than 0.15, one hundred percent of the 99 material selection AL2O3, hardness HRa 88, density 3.85.
Combination wire wheel: wheel line is divided into line wheel, ceramic wire wheel and anti jumper. A line wheel is on both sides of the structure with the ceramic ring and the bearing of the two pieces of nylon plate, also called ceramic wire wheel does not directly use the plus side plate. The structure of anti jumper is on both sides with the ceramic ring and the bearing of two pieces of ceramic plates, ceramic plates with a reverse hook or a ball, can avoid the wire line above the ring out of porcelain.
