Product Details
The characteristics of power tools are light structure, small size,
light weight, low vibration, low noise, flexible operation, easy to
control and operate, easy to carry and use, strong and durable.
Compared with manual tools, it can increase labor productivity
several times to dozens of times; it is more efficient, lower cost
and easier to control than pneumatic tools. Therefore, the internal
gears need to be precise, with low transmission noise, small gaps,
and smooth operation.
Advanced manufacturing equipment
DH has multiple CNC 7-axis 5-linkage spiral bevel gear grinding
machines and gear milling machines that can process high-reduction
ratio hypoid and transverse cured tooth coupling.
Advanced testing equipment
Utilize a high-precision gear measurement center to complete gear
pitch accuracy detection, tooth profile error detection and inverse
correction of tooth profile errors.
Professional software
Our factory has a complete set of software to realize digital
closed-loop manufacturing of spiral bevel gears, Functions such as
gear design, strength calculation, contact analysis, tool
calculation, tooth profile error reversal, etc. can be realized.
Machining methods include five tools machining(fixed setting) &
G-plete of tapper , spiral format tilt(SFT) method & hypoid
format tilt (HFT) method of Cycloid equidep, etc.
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!
