Abstract (EN): Various methods have been explored to improve the wear, friction, and thermal behaviour of polymer gears, including modifying tooth geometry and adding cooling holes. The current study aims to assess the potential of using metallic inserts to reduce operating temperature and increase load capacity. This study extends previous results by subjecting the hybrid gear rack to a static bending test under different thermal power. A loading and heating system was designed and manufactured, the temperature measured using thermography, and displacements estimated using digital image correlation. As anticipated by the developed finite element thermal model, the hybrid solution decreases the flank and root temperature, and subsequent work is needed to manufacture and validate a hybrid polymer gear. While the current experiments don¿t mimic real gear applications they were useful to characterize materials, validate models and identify possible drawbacks of a hybrid polymer-metal gear. © 2023 The Authors.
