Product Details
Products: 20CrMnTi spiral bevel gear carburizing and quenching
ground helical gear
Spiral bevel gear is a common transmission gear with the
characteristics of helical teeth and parallel shafts, which can
realize power transmission between two shafts.
20CrMnTi is a commonly used carburized steel. It can obtain good
surface hardness and core toughness through carburizing and
quenching processes. It is often used to manufacture high-strength,
wear-resistant gears, bearings and other mechanical parts.
Suitable for all kinds of transmission systems, especially for
high-speed, heavy load, high torque conditions
Products advantages:
- High hardness and wear resistance: After carburizing and quenching
treatment, the surface hardness of the gear can reach 58-64HRC. It
has good wear resistance and can withstand high contact stress and
wear resistance. It is suitable for heavy load and high-speed
working conditions.
- High load-bearing capacity: Due to the excellent properties of
20CrMnTi steel, the carburized and quenched gear has high bending
strength and contact strength and can withstand larger loads.
- Good toughness: The core maintains good toughness, which can
prevent the gear from breaking to a certain extent.
- Smooth transmission: The helical tooth design of the spiral bevel
gear makes the transmission more stable, with lower noise, and can
maintain good performance during high-speed operation.
Product shortcomings:
- The manufacturing process is complex: the carburizing and quenching
process is long and requires precise control of the carburized
layer depth and quenching process to ensure gear quality.
- Higher cost: Due to material and process requirements, the
manufacturing cost of 20CrMnTi carburized and quenched spiral bevel
gears is relatively high.
- Prone to deformation and cracks: Due to the influence of
temperature changes and material stress during the carburizing and
quenching process, gears are prone to deformation and cracks, which
need to be corrected through subsequent processing and processing.
- High requirements for shafts and bearings: Due to the high hardness
of gears, the shafts and bearings that match them also need to have
good hardness and wear resistance, otherwise it will easily cause
wear of the matching parts.

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!
