Manufacture of gears materials and processing methods

    Manufacture of gears material
    Commonly used in the manufacture of gears with steel quenched and tempered steel, hardened steel, case hardening steel and nitriding steel. Slightly lower than the strength of forged steel, commonly used in sizes larger gear; poor mechanical properties of gray cast iron can be used for light load of open gear drive; ductile iron can partially replace the steel gears; multi-purpose plastic gear at light load and low noise requirements of the place, with its paired gear generally good thermal conductivity of steel gears.
    Future Forward heavy gear, high speed, high precision and high efficiency direction, and seeks to small size, light weight, long life, and economic and reliable.
    The gear theory and development of manufacturing processes will be to further study the mechanism of tooth damage, the intensity of which is to establish a reliable basis for calculation method is to increase the carrying capacity of the gear to extend gear life theory; development represented an arc tooth profile new tooth; study of new materials and manufacturing gear gear new process; elastic deformation of the gear, manufacturing and installation errors and the temperature distribution, for gear shaping, in order to improve the smooth running gear and the full increased when the tooth contact area, thereby improving the carrying capacity of the gear.

China Gear(

    Friction, lubrication theory and research gear lubrication technology is the basic work, study elastic hydrodynamic lubrication theory, promote the use of synthetic lubricants and oils due to join in extreme pressure additives, not only can improve the carrying capacity of the tooth surface, and transmission efficiency can be improved.
   Gear processing methods
   Involute gear cutting method 2 categories, one is profiling method, using molding cutter milling a gear cogging, is "imitation pattern". Another is generating method (generating method).
   (1) hobbing hobbing: 8 module can be processed following helical
   (2) milling machine milling: straight rack can be processed
   (3) Slotting Slotting: internal teeth can be processed
   (4) Cold beat machine to fight tooth: You can chipless
   (5) gear-shaping machine planing teeth: 16 module can process the large gear
   (6) Precision casting gear: You can process large quantities of cheap pinion
   (7) grinding machine grinding teeth: precision machine tools can be processed on the gear
   (8) die casting machine casting gear: the majority of processing non-ferrous metal gear
   (9) shaving machine: a gear finishing with a metal cutting machine tools
