With the progress of electrification, demand for geared motors consisting of a high-speed motor and a reduction gear is increasing. In particular, there is a strong need for downsizing drive units for mobility applications such as automobiles, the market for which is expected to grow, so a first-mover advantage can be gained by developing a transmission unit that is both downsizing and large-reduction ratio. In this research, we focused on the bilateral gear developed by Yokohama National University as a new large-reduction-ratio mechanism that enables the significant downsizing of drive units and designed and manufactured a 50kW prototype gear for mobility applications. We also conducted a load test to verify its power transmission efficiency, temperature and vibration. This report gives an overview of the prototype bilateral gear and the results of the load test.
