Embodiment:

Figure 1 shows that the utility model is used to batch the tube shaped electric machine structural representation of a kind of optimal way of rolling screen door, among the figure, 1, the 4th, the orthogonal rotating shaft of axis, they connect by intermeshing

bevel gear

2,3, and rotating shaft 1,4 and

bevel gear

2,3 constitute the manual-operating mechanism of tube shaped electric machine; Side magnetic braking motor 22 and decelerator 23 are formed the running part of tube shaped electric machine, decelerator 23 can adopt three grades not have supporting floating solar planetary gear structure, rotating shaft 4, motor 22 all are arranged in the reel 16, and coaxial with reel 16, rotating shaft 1 is vertically set on outside the end of reel 16 as the operating side of operating mechanism.

Between transmission mechanism and the manual-operating mechanism 4 shaft coupling is installed, shaft coupling is made up of driving link 6 and driven member 25; Manual-operating mechanism rotating shaft 4 one ends are provided with pin 5, and shaft coupling driving link 6 is provided with cylindric termination 1, and the end face 15 of termination 14 contacts with pin 5, and the two constitutes the edge cam structure; The other end of shaft coupling driving link 6 has the rod member 9 that extends axially and be equipped with return spring 10, and these rod member 9 ends are provided with symmetrical pin 11; The shaft coupling driven member is one to be fixed on the dial of machine shaft, which is provided with the perpendicular symmetrical pin 24 of axis of symmetrical pin 11 on axis and the shaft coupling driving link 6, the master and slave moving part of shaft coupling all with reel 16 coaxial lines.

As shown in Figures 2 and 3, termination 14 cylindraceous is arranged with two sections end faces 15 that contact with the pin 5 of rotating shaft 4 that identical symmetry is arranged between 12, two boss 12 of two boss.After launching, every section end face 15 is the V-arrangement of forming symmetry by two sections inclined-planes.

In conjunction with Fig. 1 and Fig. 4, radially be provided with spring 13 along reel 16, spring 13 is being oppressed friction plate 7, friction plate 7 contacts with parts 8, parts 8 sleeve-like are enclosed within the periphery of driving link 6, the inner surface of sleeve 8 offers groove 26, and the pin 17 on the driving link 6 can extend into sleeve 8 and driving link 6 to be free to slide also can drive driving link 6 and overcome the damping force rotation, and said structure has constituted the damping device of generation damping force when driving link rotate.

Its operation principle is as follows, and position shown in Figure 1 is a motoring condition.

Owing to the screw 18 of regulating spring 13 belows, can change the thrust of spring 13 and 7 pairs of component sleeve 8 of friction plate, make it when rotating, can be subjected to a damping force.
