Double Differential for Electric Vehicle and Hybrid Transmissions — Sophisticated Simplicity

The fascination with the automotive differential has led to the idea to build a second differential unit around a first center unit. Both units have the same axes around which they rotate at different speeds. The potential of double differentials as ultrahigh reduction speed reducers is significant. Only the tooth count of the gears in the outer differential unit must be changed in order to achieve ratios between 5 and 80 without a noticeable change in the transmission size.

Gleason’s new 300GMS nano Gear Metrology System is built for today’s unprecedented transmission noise challenges and tooth form quality requirements. 300GMS nano delivers sub-micron analysis of tooth surface roughness after polish grinding; applies Advanced Waviness Analysis tools to detect and mitigate critical noise behavior caused by hard-to-find tooth form irregularities. More Information	e-Mobility & Low Pressure Carburizing with ECM LPC with HPGQ is optimal for drivetrain heat treatment systems with the industry transition from ICE to EV. Electric vehicle drivetrains demand very low distortion, and automotive manufacturers require very consistent, high-quality results which are achieved when performing low pressure carburizing/high pressure gas quenching in ECM vacuum furnaces.
