Manteision o powdwr meteleg offer hwb% 3a
1. isel cost, cyflym cynhyrchu swp, un-amser molding, no angen i broses gêr dannedd ar ôl molding.
2. Due i y prosesu nodweddion o powdr meteleg, mae'n can fod gwneud i gwneud olew rhannau rhannau i ffurflen iro- rhannau, ond yr effaith yn yn waeth olew bath iro wladwriaeth.
3. Mae yn dim gwastraff yn y broses y gêr hub, sydd yn gwell ar gyfer y defnydd o dur adnoddau. Mae'r manteision o powdr meteleg wedi'u cyflwyno yma. Yn rhai sefydliadau dibwys sefydliadau, meteleg gerau can ystyriwyd , o'r fath fel teganau, ac ati.

What should be paid attention to when using lubricating oil for powder metallurgy gear hubs? 1. During the smearing process, use lubricating oil extrusion tool to smear, do not apply directly by hand. Since the lubrication is intermittent, a new oil film needs to be formed every time it rotates, so the lubricating oil must have a high viscosity and strong adsorption to ensure that the new oil film covers the gear surface. 2. If the neutralization price of the lubricating oil in the powder metallurgy gear cycle oiling system has increased by 0.8-1.00 compared with the new oil, and the degree of adhesion has increased significantly, it needs to be replaced immediately. 3. In addition to applying lubricating oil to powder metallurgy gears, dust-proof measures should also be taken on powder metallurgy gears to prevent dust from entering as much as possible. What are the characteristics of the strength of powder metallurgy gears? The precision of powder metallurgy gears depends on the material expansion coefficient and mold precision.
What are the problems of thermal sleeve of powder metallurgy gear parts? With the continuous development of national industrial technology, the traditional casting process of powder metallurgy can no longer meet the needs of modern industry, so the parts and products used in many fields now need to be produced by high-tech means, but powder metallurgy is this high-tech Technological craft. So what are the problems of hot sleeve of powder metallurgy wheel parts? The problems are as follows: 1. The sintering furnace (mesh belt furnace) is sintered and protected by ammonia gas. Whether it is iron-based or copper-based, it is first mixed with powder and then pressed, then sintered and shaped, and then filled with oil. 2. Carbonitriding, nitrocarburizing, induction hardening and other heat treatments can be carried out. 3. Try carbonitriding at around 850 degrees for 4 hours. The amount of kerosene should be large. It is better not to immerse the product in heat treatment first. 4. Whether carbonitriding is possible? Minxin has tested that the United States is talking about carbonitriding. 5. The sintering furnace (mesh belt furnace) is sintered and protected by ammonia gas. No matter it is iron-based or copper-based, it is first mixed with powder and then pressed, then sintered and shaped, and then filled with oil. Powder metallurgy gear surface rust prevention: passivation and coating treatment, rust prevention is still required during transportation, and coating has an impact on later assembly and use.
