GEARING WITH INCREASED TEETH WEAR RESISTANCE
Journal Title: Проблеми тертя та зношування - Year 2018, Vol 79, Issue
Abstract
The most important criterions of gearing efficiency are teeth wear resistance. The or-der of synthesis of rack cutter instrument for manufacture of gears with increased teeth wear resistance is considered. It is based on the model of teeth wear of closed gearing that works in oil reservoir. The differential equation is derived; its solution determines geometrical parameters of original profile. The parameters depend on setpoint of comparative teeth wear of synthesizing gearing and involute gearing. The finding so-lution is used for creation of equation of working teeth surfaces in toothing.
