Run it! [Gear] metallurgical machinery leading technology innovation
Powder metallurgy mechanical gear is less chips, chip-free high-tech product.
While powder metallurgy mechanical gear throughout the powder metallurgy parts difficult to statistics alone, but both are by weight or by number of parts, powder metallurgy mechanical gear in the automotive, motorcycle proportion far in the field of powder metallurgy other big parts . Therefore, from automobiles, motorcycles can be seen that the proportion of the rise throughout the powder metallurgy parts, powder metallurgy mechanical gear in the position of the rapid development in the whole of the powder metallurgy parts. If you press the part characteristics to points, gear belonging to the structure of parts, components and structures in the whole class of iron-based parts share of absolute weight far greater than the other categories, powder metallurgy parts.
Development of metallurgical machinery gear theory and manufacturing processes will be further study the mechanism of tooth damage, which is to establish a reliable method of strength calculation basis is to improve the carrying capacity of gears, gear extended theoretical basis of life; the development of a circular arc tooth profile the new tooth representatives; study new materials and manufacturing gear gear new technology; the elastic deformation of gear research, manufacture and installation errors, and the distribution of temperature field, performed tooth modification to improve the smoothness of running gear and at full load increases the contact area between the teeth, thereby enhancing the carrying capacity of gears. Friction, lubrication technology lubrication theory and metallurgical machinery gears basic research work on the elastic hydrodynamic lubrication theory, promote the use of synthetic lubricants and extreme pressure additives added as appropriate in oil, not only can increase the carrying capacity of the tooth surface but also can improve the transmission efficiency.
