ring 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.

Segmented girth gears or large gear are used to drive large rotating systems such as dryers, rotary kilns, and horizontal mills. The flexible design concept has brought great convenience to the manufacture, transportation and assembly of the gear ring. Relying on professional program design, strong equipment processing and production capacity, and professional quality control system, we provide customers with high-precision, low-noise, high-efficiency ring gear drive solutions.

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.

Pinion gear is a part used in mechanical transmission. Material is usually forged 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 pinion gears such as spur gear, helical gear, worm 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.

Single row four point contact ball slewing ring HS series is a standard model series in China. It is made of inner ring and outer ring. The rolling balls are four point contact with the raceway. It can bear axial force, radial force and overturning moment at the same time. Outer Diameter is from 725mm to 4860mm. It is with non gear type, internal gear type and external gear type.Standard material we adopt is 50Mn and 42CrMo. Other customized material is also acceptable. We support models selection based on your application; teeth quenching and grinding; customized surface treatment like Blackening, phosphating, galvanizing, sandblasting and etc. In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings. This series models are with advantage of compact design, flexible rotating and light weight. It is widely used on rotary conveyor, welding arm and positioner, light/medium duty cranes, excavators and other engineering machines. Please feel free to tell us the application you use and we can help you choose the proper model and offer you a professional solution as soon as possible.
