[0017] The present invention will be described in detail below in conjunction with the drawings.
[0018] Such as figure 1 As shown, a flat harmonic transmission device with drum-shaped gear teeth includes a rigid wheel 1, a flexible wheel 2, a wave generator 3 and a cross roller bearing 6. The wave generator 3 is installed inside the cylinder of the flexible wheel 2, The rigid wheel 1 is fitted on the outer ring of the flexible wheel 2, the teeth of the rigid wheel 1 mesh with the teeth of the flexible wheel 2, the outer ring of the cross roller bearing 6 is connected with the rigid wheel 1 by bolts 4, and the output shaft of the flexible wheel 2 Part D is provided with threads, and the inner ring of the cross roller bearing 6 is fastened to the output shaft of the flexspline 2 through a lock nut 5. Such as figure 2 As shown, the middle of the flexspline 2 is a cylindrical part E, the outer ring of the cylindrical part E is machined with a gear tooth part F, and the end of the ...
