Research of kinematic properties and power losses of two-carrier planetary gear trains
Technical Sciences/uniri projects by experienced researchers
Modern power transmission systems are expected to offer high efficiency, compact design, and high power density per unit mass. Planetary gear trains are particularly well-suited to meet these demands due to their favorable geometry and internal structure, enabling the transfer of high torques in confined dimensions. Among them, two-carrier, single-speed planetary gear trains stand out for their simplicity, reliability, and potential for wide application, especially in the automotive and aerospace industries.
Although basic configurations of these gear systems are known and partially studied, many viable variants remain unexplored. Existing research tends to focus on a small number of established configurations, while others are overlooked due to the complexity of their kinematic analysis and the lack of efficient tools for systematic comparison. This limits the development of more optimal and efficient transmission solutions, despite the practical advantages these systems may offer in terms of adaptability and performance.
The proposed project aims to systematically explore all possible configurations of two-carrier, single-speed planetary gear trains. Key objectives include identifying achievable transmission ratios, determining corresponding efficiency levels, and classifying variants according to design and performance criteria. A dedicated comparative analysis methodology will be developed to enable objective evaluation, supported by experimental testing on custom-designed equipment for precise measurement of efficiency and dynamic behavior.
The project outcomes will contribute to a deeper understanding of two-carrier, single-speed planetary gear trains and open the door to broader industrial application where simplicity, reliability, and efficiency are essential.
