[0025] Embodiment: an industrial robot reducer flexible gear structure, as shown in Figure 1 Figure 4 As shown, it comprises a flexible gear body 1, the flexible gear body 1 is in thin-walled cup type structure, the surface of the flexible gear body 1 is provided with mating gear 2, the cup mouth of the flexible gear body 1 is provided with sealing end cover 3 by screw thread, the flexible gear body 1 is provided with output shaft 4 by clamping, the bottom end of the flexible gear body 1 is provided with output disc 5 by screw thread, the cup mouth of the flexible gear body 1 is fixedly provided with outwardly extending mounting protrusion 6, the surface of the mounting protrusion 6 is provided with a plurality of mounting holes 7, the surface center of the sealing end cover 3 is provided with shaft hole 8, the surface of the sealing end cover 3 is provided with sealing groove 9, the sealing groove 9 is provided with sealing ring 10 by clamping, the flexible gear structure adopts split type design, the sealing end cover 3 and output disc 5 can be conveniently disassembled. When cleaning is needed, only the bolts need to be removed, the end cover and output disc 5 can be removed, and the internal structure of the gear is exposed. The outer surface of the flexible gear body 1 is smooth, without complex grooves and gaps, impurities are not easy to adhere, and the use of compressed air or cleaning agent and other tools can easily clean the dust, oil stains and other impurities on the inner and outer surfaces of the flexible gear, so that the flexible gear can work in a clean environment, prolong the service life and improve the working accuracy

[0026] As shown in Figure 1 Figure 4 ​​As shown, the inner wall of the flexspline body 1 is provided with gear grooves 11, which are matched with the surface of the output shaft 4, and the surface of the flexspline body 1 is provided with a flexible support ring 12, which should have certain flexibility and resilience. This convenient cleaning design is especially suitable for industrial robots working in harsh environments such as dust and oil stains, reduces the maintenance workload and downtime, and improves production efficiency.

[0027] As shown in the drawings, Figure 1 Figure 3 As shown, the output disc 5 is threadedly connected with the flexspline body 1, the surface of the output disc 5 is provided with a plurality of output holes 13, the inner wall of the flexspline body 1 is provided with a clamping hole 14 at the bottom end, the inner wall of the clamping hole 14 is movably provided with a bearing 15, and the clamping hole 14 is connected with the bottom end of the output shaft 4 in a clamping manner,

When the industrial robot performs precise assembly, welding and other work, high-precision transmission can ensure the motion accuracy of the robot, improve product quality, and reduce the scrap rate.

[0029] Working principle: when the driving motor drives the input shaft to rotate, the input shaft and the gear grooves 11 of the flexspline inner teeth are meshed with each other, so that the flexspline produces elastic deformation.
