Abstract

A joint module is provided which includes a housing, a driving assembly, a speed reduction assembly, a first fastener, a second fastener and a third fastener. The driving assembly includes an output shaft, a lower bearing seat and a lower bearing, an inner ring and an outer ring of the lower bearing are respectively connected with the output shaft and the lower bearing seat. The first fastener fixes the lower bearing seat on the housing, and the second fastener fixes the speed reduction assembly on the housing. The third fastener fixes the input shaft of the speed reduction assembly to the output shaft. The output shaft of the driving assembly and the input shaft of the speed reduction assembly are separate structural members, which not only allows the driving assembly and the speed reduction assembly to be tested separately before assembly, but also facilitates the later maintenance.
