    Customized Large Ring Gear Spur Gear Girth gear

    Ring gear, Gear wheel or Girth gear is a part used in mechanical transmission. Material is usually forged or casting alloy steel with surface carburizing or hardening treatment. The gear has the high bearing capacity and durability in practical application, which is widely used in high speed and heavy load machinery because of its stable transmission, low impact, vibration and noise. The ring gear from our company is precisely designed using high quality raw material, and finish of the gear is with high precision too.Our quality experts check the product at each and every stage of manufacturing process according to the international industrial standards. Our company can produce different type gear ring and wheel such as spur gear, helical gear, worm gear, large ring gear according to the customer's drawing and requirements. Our product is highly appreciated amongst customers for its dimensional accuracy, excellent strength and high performance. Teeth quenching, teeth grinding and surface treatment like oxide, nitriding, sandblasting are also available.

  • High Precision Large Internal Ring Gear Girth gear Metal Spur Gear With Nitriding Treatment

    Ring gear is made of 42CrMo quenched and tempered material. Module is 4.5 and teeth No. is 69. To improve the hardness of the gear, we make nitriding treatment for it. The holding temperature of the nitriding process is generally 460-600 ℃, which is a chemical heat treatment process in which active nitrogen atoms are infiltrated into the surface of the gear. After nitriding, the distortion of the gear is small, and it has higher hardness than carburizing, which can increase wear resistance, fatigue strength, anti-seizure performance, corrosion resistance and high temperature softening resistance, etc. It is widely used in automobiles and machine tools for higher requirements of wear resistance capacity.
