Abstract
High reduction hypoid gears (HRH gears) are characterized by high transmission efficiency, strong carrying capacity, and excellent silence performance, making them suitable for precise, high-speed, and heavy-load transmission systems. This paper focuses on the dynamic meshing performance of high reduction hypoid gears, which is crucial for the integration, light weighting, and high-power-density transmission of mechatronic transmission devices. The main research contents and conclusions are summarized in tables and figures below.
