"You feed temptation to match the" production material cranes special gear you know?
Manufacturing cranes special gear commonly used steel has quenched and tempered steel, hardened steel, carburizing steel, and nitriding steel. Slightly lower than the forged steel strength steel, commonly used in a larger size gear; the poor mechanical properties of gray cast iron, can be used for light load open gear drive; ductile iron may be partially replaced by steel gear; multi-purpose plastic gear in light load and low noise requirements of local, paired cranes special gear is generally good heat conductivity steel gears.
Future special gear forward overloaded crane, high-speed, high precision and high efficiency, the direction of development, and strive to small size, light weight, long life, and economically viable.
And the development of theory and cranes special gear manufacturing process will be to 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 the crane special gear, gear extended theoretical basis of life; the development of an arc tooth tooth profile for a new representative; research of new materials and manufacturing gear gear new technology; the elastic deformation of gear research, manufacture and installation errors, and temperature distribution, performed tooth modification to improve the smoothness of running gear and increase the contact area of ??the tooth at full load, thereby increasing the carrying capacity of gears.
Friction and lubrication technology lubrication theory crane special gear in 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.
