Fig. 3 is sprocket wheel assembly structure schematic diagram.
In figure: 1 lathe bed, 2 bases, 3 chains, 4 contiguous blocks, 5 pins, 6 guide grooves, 7 side plates, 8 gussets, 9 connecting plates, 10 motors, 11 hinge wheels, 12 first minor sprockets, 13 second minor sprockets, 14 sprocket wheel setting sleeves, 15 minor sprocket end caps, 16 sprocket wheel spacer sleeves.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of chain wheel driving mechanism, comprises lathe bed 1 and chain sprocket structure.Wherein, lathe bed 1 is mainly used in the object arranging other motion, and lathe bed 1 is equivalent to the effect of guide rail.Also be provided with guide groove 6 in the centre of lathe bed 1, guide groove 6 is provided with two rectangular preiections at the midfeather certain distance of lathe bed, makes to form a groove between two rectangular preiections.The effect arranging guide groove 6 is for arranging chain 3 in guide groove 6, so the width of guide groove 6 need slightly larger than the width of chain 3, and the object that the width of selected chain 3 draws in need using according to reality is selected.The position exceeding guide groove 6 length in lathe bed 1 both sides is also respectively arranged with a contiguous block 4, fixing being arranged on lathe bed 1 of contiguous block 4.Contiguous block 4 is for fixing chain 3, and chain 3 adopts pin 5 to connect with the connection of contiguous block 4, thus makes chain 3 can be up and down.Also be provided with multiple base 2 in the bottom of lathe bed 1, base 2 be also provided with tapped hole, base 2 for by lathe bed 1 together with ground or other partial fixings.
In chain sprocket structure, comprise two side plates 7 and hinge wheel 11, first minor sprocket 12, second minor sprocket 13.Wherein, the setting that two side plates 7 are parallel, two side plates 7 are linked together with connecting plate 9 at side plate 7.Meanwhile, another side is strengthened connecting between two side plates 7 with gusset 8.Hinge wheel 11, first minor sprocket 12, second minor sprocket 13 is arranged between two side plates 7.Three sprocket wheel settings triangular in shape between two side plates 7.Wherein, hinge wheel 11 is arranged on top, and the first minor sprocket 12, second minor sprocket 13 is arranged on same level position.
