Problems solved by technology

At present, the existing godet wheels are generally made of aluminum, and the surface is coated with aluminum oxide. During high-speed operation, the surface coating of this kind of godet wheel is easily oxidized and then peeled off, causing pits on the surface of the godet wheel. This leads to threading phenomenon, which makes it impossible to use and produce normally; at the same time, when the godet wheel is running at high speed, there is friction between the shaft hole and the fixed shaft. Wear and tear will deflect the rotatio

Embodiment

[0019] Concrete preparation steps are as follows:

[0020] a) Preparation of the godet wheel body, the godet wheel body is made of silicon carbide ceramic particles as the main material, combined with a certain amount of additives, and sintered by hot isostatic pressing; wherein, the particle size of the silicon carbide ceramic particles is 0.8- 1.2um, the sintering temperature is controlled at 1550-1650°C, the pressure is 120-125MPa, the main additive is alumina or magnesia, which can effectively reduce the sintering temperature and increase the sintering density;

[0021] b) Prepare the inner ring. The main raw material of the inner ring is flake graphite, the carbon content of which is 99.5%-99.9%, and the maximum scale size is 0.2-0.4mm; the inner ring is prepared by molding process, and the prepared inner ring The thickness is 1-1.5mm, the inner surface roughness is 0.8-0.2, and the outer surface roughness is slightly larger than the inner surface roughness value;

Description

technical field [0001] The invention relates to a preparation method of a novel godet wheel, in particular to a preparation method of a novel godet wheel with superior comprehensive performance, and belongs to the technical field of textile equipment. Background technique [0002] As the people's living standard is moving from a subsistence type to a well-off type, the demand for textiles begins to shift from keeping warm to pursuing fashion and expressing individuality. By the end of this century, the overall quality of my country's national economy and comprehensive national strength will reach a new level, people's lives will reach a well-off level, and the requirements for the quantity, variety, grade and quality of textiles will become higher and higher. The textile industry must accelerate the pace of reform and establish a rapid response mechanism. , making textiles increasingly finished, matching, fashionable and personalized. [0003] In the textile industry, spinni...
