Processing Features:
1. DH precision manufacturing: Spiral bevel gears require precision
manufacturing processes due to their complex tooth geometry. Gear
teeth are typically produced using specialized cutting tools,The
accuracy of the cutting process directly affects the performance
and durability of the gear. We have multiple CNC 7-axis 5-linkage
spiral bevel gear grinding machines and gear milling machines,
which can process high-reduction ratio hypoid gears and end-face
arc tooth couplings.
2. Gear grinding: After the initial cutting process, spiral bevel
gears often need to be ground. Grinding helps improve gear tooth
surface finish, accuracy, and tooth-to-tooth contact. Ensure
correct gear meshing to reduce noise and vibration during
operation.
3. Heat treatment: Heat treatment is an essential step in
processing spiral bevel gears. It involves heating the gear to a
specific temperature and then quenching it to achieve the required
hardness and strength. Heat treatment helps improve gear durability
and wear resistance.
4. Inspection and Quality Control: Due to the critical nature of
spiral bevel gears, strict inspection and quality control
procedures are adopted during their manufacturing process. In order
to ensure the dimensional accuracy and tooth profile consistency of
the gears, we use various measurement methods, such as
three-dimensional coordinate measuring machines (CMM), and we use
the high-precision gear measurement center to complete the gear
pitch accuracy detection, tooth profile error detection and reverse
correction of tooth profile errors.
Company Profile
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!
