Effectively reduce the noise reduction planetary gear box Gear:
1, the control gear accuracy: precision gear basic requirements: proven, precision gears must be controlled gb10995-887 ~ 8 grade line faster than 20m / s gear, deviations from the limit, the ring gear runout tolerance, tolerance tooth must be stable to reach 7 accuracy. In the precision gear to reach 7, the shuttle down to the tooth portion, to prevent tooth root boss.
2, control the quality of raw materials: high-quality raw materials to produce high quality products is a prerequisite for our company and the largest amount of material 40cr 45 steel gears. No matter by what means, raw materials to the factory after the chemical composition must go through rigorous testing, measuring grain size, purity assessment. The aim is to promptly adjust heat distortion, improve processing quality tooth.
3, to prevent heat deformation: the gear blank in the rough into fine forging, normalizing or quenching and tempering treatment
4, to ensure the accuracy of gear blanks: gear precision pore size distribution requirements in the middle of the hole deviation of the difference between left and right, set at ± 0.003 ~ ± 0.005mm; tolerance but if the design requirements within the scope of the hole, must be classified , respectively, into the gear cutting process. Face runout and radial runout of the gear blank 6, will be in the range of 0.01 ~ 0.02mm.
5, gear processing measures: The tool must be purchased gear inspection, must meet aa level requirements. Must be adjacent pitch radial rake blade surface of the chip flutes differential gear after tool sharpening, maximum cumulative pitch error of the chip flutes, with the knife in front of the hole parallel axis gear inspection.
6, civilized production: gear transmission noise more than 30% from the reason burr, bump injury. Some factories in the gear box [Gearbox: Gearbox] before assembly, remove the burr and bump injury, it is a passive approach.
7, take other materials and heat treatment, surface treatment: (1) the use of powder metallurgy technology, after the gear tooth portion forming induction hardening. (2) With graphite cast iron, gear cutting, then soft nitriding. (3) 40cr material after gear cutting power engineering, soft nitriding or tooth section copper plating. The integrated, to cure gear noise, gear materials and heat treatment to the present, is to ensure the accuracy of gear blanks, gear accuracy is the key, is the basis of civilized production.
