日企将全球首次量产球形齿轮

Core Viewpoint - The article discusses the development and potential applications of a new spherical gear, which allows for 360-degree rotation in multiple directions, promising to reduce the number of components in machinery and improve efficiency in various industries [2][4][5]. Group 1: Development and Production - Kanematsu, in collaboration with Yamagata University, is set to mass-produce spherical gears globally for the first time by 2027 [2]. - NISSEI, a subsidiary of Brother Industries, has established a stable production process for spherical gears and is in discussions with about three companies to promote their adoption in industrial and precision equipment [4]. - Kanematsu has obtained exclusive rights to produce and sell spherical gears from Yamagata University and has signed a sub-license agreement with NISSEI for production and sales [4]. Group 2: Technical Advantages - Spherical gears consist of three components, allowing for a significant reduction in the number of parts needed for machinery, which can lead to lighter and more efficient designs [5]. - The transition from resin to metal materials for spherical gears has greatly enhanced their durability, making them suitable for industrial applications [4]. Group 3: Potential Applications - Spherical gears are expected to be used in humanoid robots, enabling more human-like movements, and in drones for 360-degree camera installations [7]. - In space applications, spherical gears could improve energy efficiency and reduce failure risks, particularly in solar panels for satellites [7]. - The gears may also find applications in the chemical and pharmaceutical research sectors, allowing for precise control of rotation speed and direction [7]. Group 4: Market Outlook - The global gear market is projected to reach $222.1 billion by 2025, with a 32% growth expected by 2030, driven by increased demand in automotive components and wind power generation [7]. - Kanematsu and NISSEI are currently focused on developing gears for various applications, but there may be production capacity challenges if demand expands into larger markets like automotive transmission systems [8].
