提供用于电动车驱动单元高转速化的新评估解决方案

常見問題

Q: What is the main purpose of this new evaluation solution?

A: The main purpose is to provide a solution for evaluating the cooling and lubrication of gears in EV drive units that are operating at high rotational speeds (up to 24,000 rpm).

Q: What technologies are combined in this new solution?

A: It combines Technical Support Inc.'s high-speed dynamometer testing technology with JFE Techno Research's specialized measurement using high-speed cameras and fluid dynamics analysis technology.

Q: Why is high-speed rotation a challenge for EV drive units?

A: High-speed rotation is necessary for miniaturization and efficiency but leads to technical challenges such as increased heat generation, vibration, and demands on insulation and strength, making optimal cooling and lubrication crucial.

Q: What specific aspect of gear lubrication is being evaluated?

A: The solution evaluates how cooling and lubricating oil adheres to, scatters from, and is supplied to the gear teeth under high-speed rotation, thereby visualizing and improving the analysis of the cooling and lubrication mechanism.

Q: What type of oil was used in the initial experiments?

A: Automatic Transmission Fluid (ATF) was used as the test oil in the initial experiments.
