Grinding Hypoid Gear High Ratio Miniaturization Pinion Hardened Surface

1.Strong transmission capacity

• High reduction ratio: A pair of gears can achieve a large reduction ratio, which can replace multi-stage gear transmission, simplify the mechanical structure, reduce the volume of the equipment, and reduce costs.
• Efficient torque transmission: Compared with worm gears and worms, hypoid gears have less sliding friction and lower loss during torque transmission, which can transmit more torque from the motor shaft to the load shaft, and the transmission efficiency can reach 95%-99%.

​

2.The transmission is stable

• Advantages of hypoid structure: The helix angle of the small wheel is large, so that the gear meshing and coincidence degree is large; The axis is offset, the layout is flexible, and the rigidity and strength of the small wheel are improved. The vibration and noise are low during operation, and can be used in occasions with high requirements for transmission stability.
• Gear grinding to ensure accuracy: After grinding tooth processing, the gear precision is high, the tooth shape is more accurate, the meshing is more accurate, the transmission stability is further improved, and the impact and vibration are reduced.

3.Good bearing and durability

• High strength: Hypoid gears can achieve high reduction ratio by reducing the number of small gear teeth, and at the same time, after carburizing and quenching, the tooth surface hardness is high and can withstand large loads.
• Long life: The gear grinding process makes the gear surface quality high, with good lubrication and low wear; The high reduction ratio reduces the number of gears and reduces the number of failure points; The smooth transmission also reduces the fatigue wear of the components and prolongs the service life.

4.Wide range of applications

• With the characteristics of high reduction ratio, smooth transmission and high load, it can be used in automobiles, industrial robots, reducers, military and other fields.

Our company was formerly known as Changsha Double Star Gear Industrial Co., Ltd, which was established in 1994. It is a directly affiliated university-run enterprise founded by Central South University Professor Zeng Tao, the leading expert on spiral bevel gears in China. It was later renamed as Changsha Senjie Gear Co., Ltd (abbreviated as "CSG") in 2016. CSG is a production R&D base specializing in professional design, reserch, manufacture and sales of high-quality small module spiral bevel gears and high reduction hypoid gears and cylindrical gears. In 2023, Hunan Dinghan New Material Technology Co., Ltd. was established as a specialized international export business department. CSG has strong scientific research and development capabilities and is also equipped a full set of advanced equipment including seven-axis five-linkage CNC spiral bevel gear grinding machines and gear milling machines. By making the best use of the scientific and technological achievements and equipment of the Gear Research Institute of Central South University, machanical processing, heat treatment and testing. We have developed high-quality products featuring high reduction, high speed, heavy load, low noise and less teeth for users.

With the quality policy of "scientific and technological innovation, quality first, being first-class firm and customer‘s satisfaction", we have won the trust of well-known domestic and abroad enterprises with stable and excellent quality. It is committed to be a pioneer of the industry of China's small-module spiral bevel gears, and is dedicated to providing service for any related industry requiring industrial robots, CNC turning and milling compound power tool turrets, industrial sewing machines, reducers, bicycles, power tools and aeromodelling. We sincerely look forward to your cooperation!
