1.5 Module Crown Wheel And Pinion Steel Hardened Spiral Bevel Gear For Bike

1.Rear derailleur:

• Planetary Gear Set: In many modern bicycle rear derailleurs, bevel gears are used as part of the planetary gears. These bevel gears help convert the linear motion of the chain into rotational motion of the rear wheel while allowing for quick, smooth switching between multiple gears.
• Adjust gear clearance: The design of bevel gears allows adjustment of gear clearance through axial movement, which maintains precise meshing of the gear set, prevents slippage and reduces noise.

2.Flower drum:

• Driveshaft Gear: In some bicycle hub designs, the gear on the driveshaft is tapered and meshes with the gear on the flywheel. This design helps transfer the power of the chain to the rear wheel efficiently.
• Sealing and Durability: The sealed design of bevel gears prevents dirt and moisture from entering the bearings, thereby increasing durability and maintenance intervals.

3.Internal gear hub:

• Internal gear system: In some internal gear hubs (such as internal transmission hubs), bevel gears are used to transfer the rotation of the input shaft to the internal gear system, thereby changing the transmission ratio.

• Angle meshing: The meshing surfaces of bevel gears are tapered, which allows them to transmit power at an angle. This is especially important in bicycle design because the rear wheel and chain move in different directions.
• Compact design: The bevel gear’s compact design helps reduce the bike’s weight and bulk while maintaining structural strength.
• Maintenance and adjustment: Adjustment of bevel gears is usually simple and can be achieved by tightening or loosening specific bolts to adjust the gear clearance.

DINGSCO

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!
