Noise Evaluation of S-Polymer Gears. [PDF]
Polymers (Basel), 2022 In this study, an acoustic behaviour of S-polymer gears made of the material combination POM/PA66 was investigated and compared to the standardised involute gears (E-gears). Basic evaluating characteristics included noise during operation, which is of particular significance when noise reduction is expected.
