This study systematically evaluates how material selection, progressive wear, and grease lubrication affect the noise, vibration, and harshness (NVH) performance of polymer gears, providing new insights for designing quieter, more optimized transmission systems.
This paper will review the development process, current research status, characteristics, functions, and measurement methods of TE. It will analyze the difficulties and core issues existing in the basic theory of TE, clarify the limitations and deficiencies of TE, and explore ways to overcome the shortcomings of TE.

Variable loads resulting from a working process, starting process, or operation near a critical speed will cause varying stresses at the gear teeth of a drive system. The magnitude and frequency of these loads depend upon the driven machine, the motor, the dynamic mass elastic properties of the system, and other effects.
For the research developed in this work, an existing simulation model of the generating gear grinding process based on a penetration calculation approach is used. Further, an extension of the model considering a realistic modeling of the grinding worm topography and the macro movements of the grinding worm during the process is presented. The result of the simulation is the microinteraction characteristics throughout
the grinding of the gear flank. In the end, the information about microinteraction characteristics obtained will be used for the calculation of force and energy in generating gear grinding.
When electric drives are used in vehicles, the masking effect of an internal combustion engine disappears, allowing the noise behavior of the transmission to take center stage. At the same time, peak power and torque increase, engine speeds increase, and power must be transferred optimally in both directions due to the regenerative braking system. Conventional design parameters remain important, however: The build space is limited, durability must not be compromised, and the product must still be cost-efficient. Optical metrology as part of a hybrid measurement concept helps to overcome all these challenges.
Since I have had the privilege of visiting numerous gear plants and research centers in the U.S., as well as 170 in 33 countries, and I closely watch the progression of technology, I wanted to share my observations about some technological advancements. For the purpose of this article, I will focus on three key areas: Robotics, Machine Tools, and Heat Treating.
