New energy electric drive finishing solution
2023-02-22 10:16
With the improvement of environmental awareness and emission regulations in the global market, new energy vehicles have become one of my country's new industries. In recent years, they have been in a period of rapid development. The output of new energy vehicles has increased from 340,000 in 2015 to 5.225 million in 2022. With this comes the challenge of machining new energy vehicle parts. In its key components, the electric drive assembly, the shaft gear and the housing account for a high proportion, and the processing quality of the bearing mounting holes is directly related to the performance of the overall system of the vehicle.
ReaGold has always been a leader in domestic finishing solutions. Since 2022, we have explored this field and developed a series of new products for processing electric drive housings, and have been verified by the actual processing applications and stability of well-known customers in the industry.
Processing difficulties
Processing technology selection (machine tool selection, part deformation, position, beat, etc.)
Accuracy analysis: contour, cylindricity, roundness, roughness, coaxiality
Bearing hole surface bimetallic materials and bearing hole insert processing.
Aluminum alloy materials are the first choice for housings due to their good ductility and reduced specific gravity. However, the bearing hole is generally inlaid with a steel sleeve according to its characteristics. After the shell is highly integrated, the following processing difficulties need to be overcome:
● High precision requirements
● Thin-walled parts, easy to vibrate
● Large aspect ratio
● Complex contour requirements
● High cycle requirements
● Lightweight tool design
● High tool composite degree
