Specific implementation mode
In conjunction with attached drawing, present pre-ferred embodiments are described in further details.
As shown in Figs. 1-5, a kind of to lubricate improved-type step chain, including several hinges 1, pass through adjacent chain between hinge 1
Section is formed by connecting, and the hinge 1 includes a pair of of inner plate 2, a pair of of outer plate 3, sleeve 4, axis pin 5 and roller 6, inner plate 2
It is connect with 4 interference of sleeve, outer plate 3 is connect with 5 interference of axis pin, and the axis pin 5 forms hinge movement with 4 clearance fit of sleeve
Pair, the sleeve 4 and 6 clearance fit of roller, 4 inside both sides of the sleeve are equipped with oilhole 7, and 4 both ends of the surface of sleeve are equipped with groove
8, it is equipped with the first sideshake 10 between the inner plate 2 and outer plate 3, the second sideshake 11, pin are equipped between inner plate 2 and roller 6
The first gap 13 is formed between axis 5 and sleeve 4, is formed the second gap 14 between sleeve 4 and roller 6, is passed sequentially through the first sideshake
10, groove 8 and the first gap 13 form the first oil circuit, pass sequentially through the second sideshake 11, the second gap 14, oilhole 7 and the
One gap 13 forms the second oil circuit, and 5 both sides of the axis pin are equipped with oil storage tank 9, are entered respectively by the first oil circuit and the second oil circuit
Oil storage tank 9.Two are established by the way that 4 end face of sleeve is utilized " siphonic effect " equipped with groove 8 and outer round surface equipped with oilhole 7
Lubrication channel increases by 15 loading of lubricant grease, ensures 1 sufficient lubrication of hinge；By the way that 5 outer round surface of axis pin is equipped with oil storage tank
9 and preserve extra lubricant grease 15, ensure hinge 1 for a long time lubricate.Improve to such structure design economy the profit of hinge 1
