Problems solved by technology

Although this structure is compact, due to the uneven force in the circumferential direction of the gears and the cantilever state of the gears, it is easy to produce abnormal noises when the three axes are linked, and even abnormal sounds will be generated when the single axis rotates, which affects the gears. life, affecting the quality of the product

Abstract

The invention discloses a robot shaft installation structure. The robot shaft installation structure comprises a fourth shaft, a fifth shaft, a sixth shaft and a motor seat, wherein the fourth shaft sleeves the fifth shaft; the fifth shaft sleeves the sixth shaft; a first bearing sleeves the end portion of the sixth shaft; an installation hole used for installing the first bearing is formed in the motor seat; the installation hole is provided with an elastic component clamped by the inner wall of the installation hole and the first bearing. According to the robot shaft installation structure disclosed by the invention, the end portion of the sixth shaft is supported on the motor seat by arranging the bearing on the end portion of the sixth shaft, the position inserting in the motor seat, of the sixth shaft is prevented from presenting a cantilever structure, and a gear on each shaft is uniform in stress in a peripheral direction, thus the gears can be prevented from generating an abnormal noise during shaft rotation, the service lives of the gears can be prolonged, and finally the quality of the product can be improved.

Description

technical field [0001] The invention belongs to the technical field of industrial robots, in particular, the invention relates to a robot shaft installation structure. Background technique [0002] The fourth, fifth and sixth axes of industrial 6-axis robots are generally placed in the same motor base, so the gear transmission mechanisms of the three axes must be on the same center line, and the more compact the structure, the better, and do not affect each other. In the existing design method, the part where the sixth shaft is inserted into the motor base is set as a cantilever structure, and the gears of each shaft do not form a whole, and the gear at the end of the sixth shaft located in the motor base is locked and positioned by a round nut . Although this structure is compact, due to the uneven force in the circumferential direction of the gears, and the gears are in a cantilever state, it is easy to produce abnormal noise of the gears when the 3-axis is linked, and e...
