This helical gear features 113 teeth; a higher tooth count increases the contact ratio, meaning more pairs of teeth share the load simultaneously during meshing. This results in more uniform load distribution across individual teeth, significantly reducing transmission shock and vibration, and quieter operation—making it ideal for applications requiring smooth performance and low noise levels. Furthermore, the multi-tooth engagement ensures a more even distribution of loads, thereby lowering the contact stress on individual teeth.
Additionally, the OEM gear helical gear is manufactured from 16MnCr5 steel using a carburizing and quenching process, achieving a surface hardness of HRC 58–62. This provides exceptional wear resistance, enabling the gear to withstand prolonged, high-frequency meshing friction while effectively preventing tooth surface wear and pitting, ultimately extending the gear’s service life.
