The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides an eleven roller ceramic roll body, includes transmission end semi-axis and non-transmission end semi-axis, non-transmission end semi-axis nestification is in seamless steel pipe dabber, and the tip of seamless steel pipe dabber is equipped with 60 chamfers, and the seamless steel pipe dabber passes through the welded layer and is connected with non-transmission end dabber, and the surface of seamless steel pipe dabber is equipped with the rubber layer, and the outside nestification on rubber layer has a plurality of ceramic nipple joints.
In particular, the weld layer is located at the position where the 60 ° chamfer is to be welded.
Specifically, the seamless steel pipe mandrel has the specification of phi 106mm, the thickness of 18mm and the length of 6010 mm.
Specifically, the length of the non-transmission half shaft embedded into the seamless steel pipe mandrel is not less than 600 mm.
Specifically, the specification of the ceramic short section is that the wall thickness is 20mm and the length is 650 mm.
The utility model has the following beneficial effects: 1) the surface hardness of the roller body is high. The hardness of the surface of the ceramic roller can reach 80-90HRC, which is much higher than that of the surface of the traditional stainless steel roller (not more than 40HRC), and the surface of the roller body is more wear-resistant;
2) the roller body is impact-resistant. The ceramic short section is vulcanized in a vulcanizing tank, and the three-layer structure of the ceramic short section, the rubber layer and the seamless steel tube is vulcanized and connected into a whole;
3) smooth surface and no adhesion. Grinding after vulcanization, wherein the surface roughness of the roller body is less than or equal to 0.8 mu m;
4) light weight and high mechanical strength. The half shaft at the end part of the seamless steel pipe is connected in an interference fit mode, and the end part is beveled and fully welded by carbon dioxide arc welding. Not only can the weight of round steel not be used, but also the mechanical strength of the roller body can be improved;
5) the service life of the eleven-roller body is prolonged to more than 24 months from the original 12 months, so that the production cost is reduced, and the economic benefit is improved.
