Arc Spiral Bevel Gear Reduction 14.5° 20° Pressure Angle

Products: Arc Bevel Gear Spiral Reduction Gear (14.5° and 20° Pressure Angle)

The main parameters of spiral bevel gear include the following:

1.Module (m): Module is an important parameter to measure the size of the gear. It determines the size and load-bearing capacity of the gear. The larger the module, the larger the size and load-carrying capacity of the gear.

2. Pressure angle (α): The pressure angle refers to the angle between the gear tooth surface and the tooth top. It has a certain impact on the transmission performance and strength of the gear. Commonly used pressure angles are 14.5°, 20°, etc.

3. Number of teeth (z): The number of teeth is one of the basic parameters of the gear, which determines the transmission ratio and structural size of the gear. Calculate the appropriate number of teeth based on design requirements and transmission ratio.

4. Helix angle (β): Helix angle refers to the angle between the gear tooth line and the axis. The size of the helix angle directly affects the transmission direction, transmission stability and load-bearing capacity of the gear. Choose the appropriate helix angle according to actual needs.

5.Tooth surface hardness (HBS, HRC): Tooth surface hardness refers to the hardness and wear resistance of the gear surface. Select the appropriate tooth surface hardness according to the working conditions and usage requirements to ensure the service life and stability of the gear.

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!
