Title: Masahiro Tsunemi: Innovator in Gear Mechanisms
Introduction
Masahiro Tsunemi is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of gear mechanisms, holding a total of 4 patents. His innovative designs focus on improving the efficiency and durability of mechanical systems.
Latest Patents
Tsunemi's latest patents include a gear mechanism and a reduction planetary gear. The gear mechanism features inner and outer gear teeth formed of high-tooth, with an engagement ratio configured to be 2.0 or more. This design allows for a continuous gear engagement of at least two pairs of gear teeth, reducing contact face pressure and bending stress. Consequently, the durability limitations of the gear mechanism are improved, and the need for increased hardness of the inner gear teeth is lessened.
His second patent involves a driving unit that comprises a hydraulic motor and a reduction gear. This invention utilizes a multiple-stage planetary gear type reducer to reduce the rotation speed of a hydraulic motor. The structure of the driving unit allows for the trunnion boss to be supported at both ends, dispersing the load and enabling a reduction in diameter. Additionally, the output shaft of the hydraulic motor and the input shaft of the reducer are formed as a single rotating shaft, optimizing the driving unit for downsizing and improved durability.
Career Highlights
Throughout his career, Tsunemi has worked with reputable companies such as Nabco Limited and Nippon Air Brake Corporation. His experience in these organizations has contributed to his expertise in mechanical engineering and innovation.
Collaborations
