Module 0.5-20 Precision Cylindrical Helical Spur Gear With Long Diameter For Industrial Transmission

Large module cylindrical gears refer to cylindrical gears with larger modules. Their main features include:

• Large load-bearing capacity: Due to the larger module, the tooth width and thickness of the gear also increase accordingly, so its load-bearing capacity is greater than that of small module gears.
• Good wear resistance: The tooth surface contact stress of large module gears is relatively small, so it has good wear resistance and can withstand large loads and impacts.
• Smooth transmission: The meshing characteristics of large module gears are better, and the vibration and noise during the transmission process are relatively small, making the transmission more stable.
• High accuracy requirements: Since large module gears are usually used in important transmission devices, there are high requirements for the manufacturing accuracy and installation accuracy of the gears.
• Difficulty in design and processing: The design and processing of large-module gears are relatively complex, requiring the use of larger processing equipment and higher processing accuracy.
• Wide range of applications: Large module gears are widely used in transmission devices with heavy load, high speed, and high precision requirements, such as large machinery, mining machinery, wind power equipment, etc.
• Higher cost: Due to the difficulty of design and processing, as well as the higher material and processing costs, the cost of large-module gears is usually higher.

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!
