What are the steps for Hezong Heavy Industry to design a planetary gear reducer?

Planetary gear reducer design is the core work of Planetary gear reducer companies and is also a key link in ensuring that the performance of planetary gear reducer meets customer needs.

As an enterprise that has been deeply engaged in the field of mechanical transmission for more than 10 years, Hezong Heavy Industry has successively developed and designed N-series planetary gear reducers, C-series plane secondary envelope toroidal worm reducers and other reducer products, and has accumulated rich experience in planetary gear reducers design.

So, what are the specific steps for Hezong Heavy Industry to design a planetary gear reducer?

(1) Communicate with customers and conduct demand confirmation analysis

Hezong Heavy Industry first communicates with customers fully to understand the specific needs and technical requirements of customers, including output torque, speed range, space limitations, etc., and combines the needs of customers to determine the basic design parameters of the reducer, such as transmission ratio, layout form, axial, radial dimensions, etc.

(2) Hezong Heavy Industry held an internal meeting to determine the preliminary design plan

The technical team of Hezong Heavy Industry determines the appropriate type of planetary gear reducer based on the basic design parameters of the reducer, such as single-stage, multi-stage, reduction ratio, etc., and then designs the structure of the planetary gear reducer, including the layout and size of components such as planetary wheels, sun gears, internal ring gears, bearings and shells.

In addition, at this stage, Helong Heavy Industry will complete three aspects of work, including calculating gear parameters, calculating gear module, number of teeth, pressure angle and other parameters to ensure the accuracy and reliability of gear transmission. It also includes the analysis of strength and stiffness of gears, bearings, shafts and other components to ensure that the design meets the load-bearing capacity and stability requirements, and optimizes the structure of the planetary gear reducer to improve transmission efficiency and reduce size.

(3) Conduct material selection and process design

Suitable materials can effectively improve the performance of planetary gear reducers. In the design stage, appropriate materials should be selected, such as high-quality alloy steel, cemented carbide, etc., to ensure the service life and performance of parts. The design, manufacturing and processing technology of planetary gear reducers are also closely related to the performance of planetary gear reducers. Therefore, in this step, specific processes in the process of heat treatment, gear processing, assembly, etc. should also be determined to ensure product quality and accuracy.

When designing planetary gear reducers, Helong Heavy Industry mostly uses 20CrMnTi carburizing and quenching to grind teeth, which has the advantages of multi-tooth shunt load, stable and reliable operation, and high mechanical efficiency.

(4) Complete experimental verification and production delivery

Finally, Hezong Heavy Industry manufactures the prototype of the planetary gear reducer for testing and verifying, testing its performance, noise and life indicators, and optimizing the design based on the test results to improve the performance and reliability of the product.

Finally, Hezong Heavy Industry produces and manufactures planetary gear reducers based on the design drawings, and tests all products before leaving the factory to ensure that the products meet the design requirements.
