Embodiment Construction
[0036] Examples such as figure 1 As shown, a harmonic reducer includes a rigid wheel 1, and a flexible output device is connected to the rigid wheel 1. The flexible output device includes a flexible wheel 2 and an output shaft 6, and the flexible wheel 2 and the output shaft 6 are integrally formed. .
[0037] The output shaft 6 and the rigid wheel 1 are rotationally connected by a cross roller bearing, the cross roller bearing is composed of a needle groove 9 and a cross needle roller 4, and the needle groove 9 is formed integrally with the rigid wheel 1 The outer needle groove and the inner needle groove integrally processed with the output shaft 6.
[0038] The end of the output shaft 6 is sealed and connected with the rigid wheel 1 through the sealing ring 5 .
[0039] The flexible spline 2 and the rigid spline 1 are driven through the meshing transmission of the internal teeth 12 and the external teeth 13;
[0040] The flexspline 2 is provided with a bearing raceway 3 ...
