Gleason Bevel Gear Modulu 3.5 With 55 Teeth For Seven Speed Bicycle

• Tooth Structure: The spiral tooth design of the gear provides a stable transmission with reduced noise and impact due to its larger overlap and simultaneous engagement of multiple teeth.
• Transmission Characteristics: Spiroid gears can transfer force between intersecting shafts, offer a wide range of transmission ratios, and are robust enough for heavy-duty applications.
• Processing and Manufacturing: The manufacturing process is intricate, requiring special equipment and high precision, which makes it costly but ensures high-precision transmission.
• Applications: These gears are used in high-stability and reliability-demanding applications like automotive differentials and aero engines.
• Role in a Seven-Speed Bike: Spiroid gears enable the transmission of power from horizontal to vertical in a compact seven-speed bike design, preventing chain drops, and facilitating variable speed transmission through a multi-stage mechanism to suit various terrains.

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!
