Strain wave gear with outwardly protruding flange for direct connection
A recently granted patent (Publication Number: US11964389B2) discloses a strain wave gear system designed for use in robot joints, featuring an outer ring, an inner ring with internally toothed gear, a flex spline with an externally toothed gear, and a wave generator to facilitate rotation. The inner ring includes an outwardly protruding flange for direct connection to objects, with the outer ring and flange designed to create a larger gap towards the exterior of the gear. The system also includes internal bearings, support bearings, and encoder components for precise positioning.
Moreover, the patent extends to a robot joint incorporating the strain wave gear system, with a joint motor driving the output flange relative to the housing. The gear system allows for smooth rotation and precise positioning, crucial for robotic applications. Additionally, a second outwardly protruding flange with an encoder track and reader enhances the system's functionality, providing accurate feedback on the inner ring's position. The design also allows for easy connection between multiple robot joints, enhancing the overall flexibility and efficiency of robotic arms in various applications.
