Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.Explanation is below to adopt the mode exemplifying, but protection scope of the present invention should not be limited to this.
The present embodiment is to consist of line shaft 11, output bearing pin 10, eccentric flange 5, eccentric roller 6, eccentric Roller Shaft 7, speed governing Moving plate 9, the quiet dish 3 of speed governing and speed disk the bearing 15 and quiet dish installation of speed governing lattice framing 1 etc.
One end of line shaft 11 is connected with power plant, and its other end connects eccentric flange 5 Yi Ce centers.Eccentric roller 6(can adopt rolling bearing, also can adopt sliding bearing or roller sleeve, the present embodiment adopts rolling bearing, therefore be also set with packing ring 12 in eccentric Roller Shaft 7) be sleeved in eccentric Roller Shaft 7, a lifting device is at the eccentric position of eccentric flange 5 one sides.
On speed governing Moving plate 9, have axial eccentric chute 8(through hole), on eccentric flange 5, the eccentric roller 6 of suit is plugged in this bias chute 8, in the another side of speed governing Moving plate 9, output bearing pin 10 is installed; The cylindrical of speed governing Moving plate 9 is with ladder step, for the inner ring of speed disk bearing 15 is installed; The quiet dish 3 of speed governing is a lid shape sleeve, and centre has circular hole, and in its endoporus, band is useful on the seam step of the outer ring that speed disk bearing 15 is installed; After the quiet dish 3 suit speed disk bearings 15 of speed governing, with circlip for hole 13 location.The quiet dish 3 of speed governing, speed governing Moving plate 9 form stepless speed regulation dish together with speed disk bearing 15.The quiet dish 3 of speed governing Moving plate 9 and speed governing is installed the space of rear both ends of the surface, seals respectively with little dust cover 4 and large dust cover 14.The joint shaft bearing 2 of the joint shaft bearing 16 of output connecting rod two and output connecting rod one is all sleeved on output bearing pin 10.The quiet dish of speed governing is installed the both sides, bottom that lattice framing 1 is fixed on the quiet dish 3 of speed governing.During installation, first line shaft 11 is connected with power plant, then, regulate the quiet dish 3 of speed governing, allow the central position (its bias d is 35mm) of misalignment eccentric flange 5 of the speed governing Moving plate 9 in the middle of it, with screw, the quiet dish of the speed governing of the quiet dish of speed governing 3 both sides, bottom is installed to lattice framing 1 and be fixed in frame.
During use, power plant drive line shaft 11 to rotate together with eccentric flange 5, the eccentric Roller Shaft 7 being loaded on eccentric flange 5 drives speed governing Moving plate 9 to rotate, owing to the center of speed governing Moving plate 9 and the center of eccentric flange 5 departing to some extent, when the eccentric chute 8 on speed governing Moving plate 9 goes to offset direction, its bias reduces gradually, now, the movement velocity of output connecting rod 2 16 and output connecting rod 1 also reduces gradually, corresponding to the inlet wire stage of crochet needle; When the eccentric chute 8 on speed governing Moving plate 9 goes to non-offset direction, its bias increases gradually, and now, the movement velocity of output connecting rod 2 16 and output connecting rod 1 also improves gradually, corresponding to exiting the stage of crochet needle.Eccentric roller 6 can reduce eccentric roller 6 resistance in eccentric chute 8.
The stepless speed changes devices that firecrackers braiding apparatus of the present invention is used, supports the use with firework weaving machine structure, can weave the firecrackers of all size.
