[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] Please see Figures 1 to 7 The present invention provides an integrated harmonic reducer, comprising a flange 1, a rotating shaft 2 and a harmonic reducer assembly 3, wherein the harmonic reducer assembly 3 comprises a wave generator 31, a flexible wheel 32 and a steel wheel 33 connected sequentially from the inside to the outside.

[0030] The flange 1 is provided with a receiving groove 101, which is recessed on the surface of the flange 1 and has a bottom surface and a side surface.

[0031] The steel wheel 33 is provided with a convex ring 331, which protrudes from the surface of the steel wheel 33. The convex ring 331 is disposed in the receiving groove 101, and the convex ring 331 fits against the side of the groove. The distance between the convex ring 331 and the bottom surface of the groove is set.

[0032] The distance X1 between the wave generator 31 and the bottom surface of the receiving groove 101 is greater than the distance X2 between the convex ring 331 and the bottom surface of the receiving groove 101.

[0033] Specifically, in this embodiment, the harmonic deceleration assembly 3 includes a wave generator 31, a flexible wheel 32, and a steel wheel 33 connected sequentially from the inside to the outside. The steel wheel 33 has a cavity, and the flexible wheel 32 is located inside the cavity. The steel wheel 33 has a convex ring 331, which is located close to the cavity. The convex ring 331 starts from the upper surface of the steel wheel 33 and extends in a direction away from the upper surface. The flange 1 has a receiving groove 101, and the convex ring 331 is embedded in the receiving groove 101. The distance between the upper surface of the convex ring 331 and the bottom surface of the receiving groove 101 is set. The distance X1 between the wave generator 31 and the bottom surface of the receiving groove 101 is greater than the distance X2 between the convex ring 331 and the bottom surface of the receiving groove 101. The rotating shaft 2 is mounted on the flange 1 and fixedly connected to the wave generator 31. An external drive source is connected to the rotating shaft 2 to drive the rotating shaft 2 and the harmonic deceleration assembly 3 to rotate, thereby achieving the purpose of deceleration.

[0034] By setting the distance X1 between the wave generator 31 and the bottom surface of the receiving groove 101 to be greater than the distance X2 between the convex ring 331 and the bottom surface of the receiving groove 101, the normal rotation of the wave generator 31 is ensured during the rotation of the external drive source driving the rotating shaft 2 and the harmonic deceleration assembly 3, thus avoiding interference and achieving the purpose of connecting the harmonic deceleration assembly 3 with drive sources of different specifications to achieve normal operation.

[0035] The flange 1 includes an upper plate body 11 and a lower plate body 12. The upper plate body 11 has an upper through hole, and the lower plate body 12 has a lower through hole. The central axis of the upper through hole coincides with the central axis of the lower through hole. The rotating shaft 2 passes through the upper through hole and the lower shaft hole and is connected to the wave generator 31. The upper plate body 11 is connected to an external drive source, and the lower plate body 12 is connected to the harmonic deceleration assembly 3. The structural design of the upper plate body 11 and the lower plate body 12 facilitates production and assembly.

[0036] The wave generator 31 includes a connector 311, a flexible inner ring 312, a flexible ball 313, and a flexible outer ring 314. The rotating shaft 2 is fixedly connected to the connector 311. The flexible inner ring 312 is sleeved on the outside of the connector 311 and connected to the connector 311. The flexible ball 313 is disposed between the flexible inner ring 312 and the flexible outer ring 314.

[0037] The upper surface of the connector 311 is lower than the upper surface of the flexible inner ring 312, further reducing the possibility of mutual interference after assembly.

[0038] The flexible inner ring 312 is provided with a first ring groove 3121, and the flexible outer ring 314 is provided with a second ring groove 3141. The flexible ball 313 is slidably connected to the first ring groove 3121 and the second ring groove 3141. The arrangement of the first ring groove 3121 and the second ring groove 3141 ensures that the flexible ball 313 moves within a limited space within the rolling range between the first ring groove 3121 and the second ring groove 3141.
