Installation pose self-adaptive industrial robot joint lubricating structure

The invention belongs to the technical field of robots, and particularly relates to a mounting pose self-adaptive industrial robot joint lubricating structure. The base, the speed reducer and the waist seat are sequentially and coaxially installed on the center cylinder, the waist seat is connected with the output end of the speed reducer, and the speed reducer drives the waist seat to rotate relative to the center cylinder; the base is provided with a base cavity, the waist seat is provided with a waist seat inner cavity, and the base cavity and the waist seat inner cavity are both communicated with a lubricating cavity of the speed reducer. The self-adaptive mounting device can be self-adaptive to the mounting form of the robot, is not only limited to forward mounting, inverted mounting and side mounting, is also suitable for being mounted on a moving vehicle and a positioner, and can ensure good lubrication, high self-adaption and wide application range when the axial direction of a shaft of the industrial
