Embodiment

Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.

Fig. 2 a Universal drive chain structure of the present invention plan view; Fig. 2 b is the plan view of Fig. 2 a; Fig. 3 a is the carrier bar plan view that turns to of the present invention; Fig. 3 b is Fig. 3 a plan view; Fig. 4 uses Universal drive chain of the present invention to be connected to three dimensional space sprocket driving schematic diagram; Fig. 5 is the plan view of Fig. 4; Fig. 6 is the left side view of Fig. 4.

Need to prove, the present invention adopts the parts of prior art, uses same sequence number with prior art.

As shown in Fig. 2 a, Fig. 2 b, the invention provides a kind of Universal drive chain 10, described Universal drive chain 10 comprises: a plurality of chain links 24, a plurality of bearing pin 30; The chain that in described each chain link 24, two intervals is arranged and be arranged in parallel rolls 21.
