Spur Large Diameter Ring Gear Mill Girth Gear With 220 ~ 240 Hardness
1. Introduction of large ring gear
The big gear ring is the main driving part of the rotary kiln, mill and other equipment. The pinion is driven by the motor, and the pinion is driven by the big gear mounted on the barrel, so that the mill is driven, and the big gear is closed with the barrel.
Because of the large gear ring modulus and large diameter, the machined gear ring of the Great Wall adopts the spoke plate structure, which is composed of two and a half gear rings.
2. Product parameters of big ring for mill girth gear
| The big gear ring | ⑴GS42CrMo4 alloy cast steel (enterprise standard) HB 220 ~ 240 The half structure, Y type plate. (3) oblique tooth. (4) Reasonable sealing and alignment structure. | ⑴ Outside refining of molten steel furnace (argon blowing and R-H vacuum treatment). (2) The special cold mold sand hanging technology is adopted to ensure the density of casting and tooth. (3) Normalizing treatment (proprietary technology) to ensure tooth surface hardness. (4) After rough hobbing, release aging, repair the joint surface, and then fine rolling ⑸ homemade hob precision hobbing. | ⑴ Mechanical properties and chemical composition of casting blank (internal control standard). (2)The ultrasonic crack detection after rough machining. ⑶ half finishing, finishing ultrasonic inspection and magnetic particle inspection. (4) Tooth surface magnetic particle inspection, hardness inspection. ⑸ Check tolerance of tooth profile. ⑹ No-load test of general assembly before delivery, check the meshing accuracy of large and small gears. |

3. Case introduction of large ring gear mill girth gear
(1) The largest ring gear in China -- the largest ring gear in the world is coming off the assembly line in Luoyang Zhongxin Heavy Machinery Group Co., LTD., Henan Province. The ring has a diameter of 9.936 meters, an inner diameter of 7.950 meters, and a total weight of 80 tons. The outer end of the ring is lined with 274 teeth 0.9 meters high.
(2) Citic Heavy Machinery Co., Ltd. has signed a production contract with Wuhan Iron and Steel Group to manufacture the world's largest oxidized pellet sintering kiln for it. As a key part of sintering kiln, the processing of large ring gear attracts attention. Previously, Citic heavy machinery processing ring maximum diameter of 8.8 meters. The successful production of large gear ring of Wuhan Iron and Steel Co., Ltd. has achieved another significant breakthrough in the history of Chinese and world gear ring processing. The ring has a diameter of 9.936 meters, an inner diameter of 7.950 meters, and a total weight of 80 tons. The outer end of the ring is lined with 274 teeth 0.9 meters high. The successful production of large tooth ring has achieved another significant breakthrough in the history of Chinese and world tooth ring processing.
(3) On January 12, 2014, CITIC Heavy Industries successfully processed AGMAQ10 precision large gear ring. "Q10" is an AGMA Grade 10 precision measure of the state of THE art in the manufacture of large gear rings for today's transmissions.
