A recently granted patent (Publication Number: US11964754B2) discloses a gear box design featuring a housing, an actuator, and a bearing assembly with an outer raceway, a cylindrical housing, an annular bearing, a sensor for monitoring bearing conditions, and a linkage connecting the actuator to the bearing assembly. The output shaft is rotatably coupled to the bearing assembly, making it suitable for applications such as tail rotor gear boxes in helicopters where blade pitch adjustments are crucial.

Additionally, the gear box design includes features like a wire passage for sensor connections, a clevis for linkage attachment, and provisions for securing the linkage with fasteners. The sensor monitors parameters like temperature and vibration of the annular bearing, ensuring optimal performance and maintenance of the gear box. The design also allows for easy wiring and maintenance, making it suitable for aircraft applications where reliability and performance are paramount.
