Document Type and Number:
WIPO Patent Application WO/2024/074154
Kind Code:
A1
Abstract:
A mechanical arm (10) and joint modules (11) thereof. Each joint module (11) comprises a joint housing (111), a driving assembly (112), and a speed reduction assembly (113). The driving assembly (112) comprises an output shaft (1121), a rotor (1122) connected to the output shaft (1121), and a stator (1123) connected to the joint housing (111). The rotor (1122) is located on the inner side of the stator (1123). An input shaft (1131) of the speed reduction assembly (113) is fixed on the output shaft (1121). The driving assembly (112) further comprises an upper bearing seat (1125) and an upper bearing (1127), the upper bearing seat (1125) is located on the side of the driving assembly (112) facing away from the speed reduction assembly (113) and is connected to the joint housing (111), an inner ring and an outer ring of the upper bearing (1127) are respectively connected to the output shaft (1121) and the upper bearing seat (1125), and the orthographic projections of the upper bearing (1127) and the stator (1123) along the radial direction of the output shaft (1121) partially overlap.
