Embodiment
Below, based on accompanying drawing, the mode of execution specialized by chain of the present invention is described.In addition, when being described chain, as shown in Figure 1 length direction X, the width direction Y of chain are defined respectively.When forming chain link 13 by a pair link plate 12, as shown in Fig. 2 and Fig. 5, the inner side of chain, outside are defined respectively.
As shown in Figure 1, chain 11 is formed by being connected in series by multiple chain link 13 formed by a pair link plate 12.The front end of a chain link 13 in adjacent chain link 13 connects in the mode that can rotate relative to the rear end of another chain link 13.Chain 11 possesses multiple chain link 13, cylindric lining 14 and columned pin 15.Lining 14 is assembled to keep the mode of the distance between two link plates 12 relative to a pair link plate 12.Adjacent chain link 13 connects in the mode of freely rotating by being inserted into lining 14 by pin 15.
As shown in Figure 3, chain link 13 is adjacent with another chain link 13 with the state of the end of wider side, the interval between the link plate 12 end of side narrower for the interval between link plate 12 being inserted another chain link 13.In this state, insert lining 14 by pin 15, thus multiple chain link 13 is connected successively at the length direction X of chain 11.Chain 11 is such as transporting article or transferring power.In this case, chain 11 advances to a direction by being stretched at the length direction X of chain 11.The length direction X of chain 11 is consistent with the movement direction of chain 11.
As shown in FIG. 4 and 5, link plate 12 is formed by steel etc. and is formed by forging substantially rectangular.The two ends of link plate 12 are the part that is connected with the link plate 12 of another chain link 13 and with fillet.Link plate 12 has: the 1st end 20 and the 2nd end 21, and it extends to length direction X; And intermediate portion 22, it is arranged between the 1st end 20 and the 2nd end 21, and intersects with length direction X.
Intermediate portion 22 is formed in the mode that its side, the 1st end 20 is more bending than the 2nd side, end 21.Therefore, the interval between the 1st end 20 of two link plates 12 than two link plates 12 the 2nd end 21 between interval narrow.
That is, the link plate of link plate 12 as the inner link of plate chain near the 1st end 20 plays a role.Further, the link plate of link plate 12 as the outer link of plate chain near the 2nd end 21 plays a role.In this, chain 11 is interposed between the different eccentric chain in the front-end and back-end of chain link 13 between also can being called between link plate 12.
As shown in FIG. 4 and 5, the thickness of intermediate portion 22 is greater than the thickness of the 1st end 20 and the 2nd end 21.The thickness of the 1st end 20 is identical with the thickness of the 2nd end 21.Intermediate portion 22 possesses the 1st cross part 22a and the 2nd cross part 22b.1st cross part 22a and the 1st end 20 are with the 1st angular cross.2nd cross part 22b and the 2nd end 21 are with the 2nd angular cross, and the 2nd angle is less than the 1st angle.The thickness of the 1st cross part 22a is greater than the thickness of the 2nd cross part 22b.
Intermediate portion 22 is obtuse angle relative to the intersecting angle of the 1st end 20 and intermediate portion 22 relative to the crossing angle of the 2nd end 21.That is, the 1st cross part 22a and the 1st end 20 and the 2nd end 21 are respectively with oblique-angle intersection.Further, the 2nd cross part 22b also with the 1st end 20 and the 2nd end 21 respectively with oblique-angle intersection.
1st end 20 of link plate 12 is formed the lining patchhole 23 for the chimeric circle of the lining 14 shown in Fig. 1.Lining patchhole 23 runs through link plate 12 along the thickness direction of link plate 12.The circular annular convex 24 of being surrounded by lining patchhole 23 is formed in the 1st end 20 of link plate 12.Annular convex 24 is given prominence to laterally from the outer side surface 20a of link plate 12.
Be formed in the 2nd end 21 of link plate 12 for the chimeric pin insertion hole 25 of the pin 15 shown in Fig. 1.Pin insertion hole 25 runs through link plate 12 along the thickness direction of link plate 12.The diameter of pin insertion hole 25 is less than the diameter of lining patchhole 23.Intermediate portion 22 is formed substantially rectangular hole 26.Link plate 12 has the stepped part 21b of semicircle arcuation at the inner side surface 21a of the 2nd end 21.
As shown in Figure 1 and Figure 2, the external diameter of the two end part 14a of lining 14 is less than the external diameter of intermediate portion 14b.In this case, be configured to can be chimeric with lining patchhole 23 for the external diameter of the two end part 14a of lining 14.The external diameter of the two end part 14a of lining 14 is slightly less than the internal diameter of annular convex 24.The external diameter of the intermediate portion 14b of lining 14 is less times greater than the internal diameter of lining patchhole 23.
Pin 15 has base end part 15a, the intermediate portion 15c and tip portion 15b of configuration on coaxially.The external diameter of base end part 15a is greater than the external diameter of tip portion 15b.The external diameter of intermediate portion 15c is less than the external diameter of base end part 15a and is greater than the external diameter of tip portion 15b.The external diameter of intermediate portion 15c is configured to be inserted into pin insertion hole 25.The external diameter of base end part 15a is less times greater than the external diameter of pin insertion hole 25.The internal diameter of lining 14 is less times greater than the internal diameter of pin insertion hole 25.This is because though pin insertion hole 25 has the diameter roughly the same with the intermediate portion 15c of pin 15, but in order to keep Run lubricating oil between lining 14 and pin 15, the internal diameter of lining 14 needs to be set to less times greater than intermediate portion 15c.
Then, the assembling method of chain 11 is described.
As shown in Figure 1 and Figure 2, when assembling chain 11, in order to form the 1st chain link 13, and 2 link plates 12 being configured abreast, and lining 14 is inserted into the lining patchhole 23 of two link plates 12.Now, the top end of the two end part 14a of lining 14 is configured to roughly align with the top end of annular convex 24.Then, between the two end part 14a circular oil seal 30 being embedded annular convex 24 and lining 14.Then, after outer circumferential face O RunddichtringO 31 being embedded in annular convex 24, further to be fitted together to circular seal ring 32 from outside by the mode that O RunddichtringO 31 covers.
Then, as shown in FIG. 2 and 3, between the 2nd end 21 of a pair link plate 12 of the 1st end 20 of a pair link plate 12 of formation the 1st chain link 13 being inserted formation the 2nd chain link 13.Now, abutted with the stepped part 21b of the link plate 12 forming the 2nd chain link 13 by the seal ring 32 of the 1st chain link 13, thus determine the position of the 1st chain link 13.
In this condition, the center of the lining 14 of the 1st chain link 13 is consistent with the center of the pin insertion hole 25 of the 2nd chain link 13.Then, pin 15 is inserted the pin insertion hole 25 of the 2nd chain link 13 and the lining 14 of the 1st chain link 13.Now, pin 15 is inserted into pin insertion hole 25 and lining 14 from tip portion 15b.
The base end part 15a of pin 15 abuts with the outer side surface of another link plate 12 forming the 2nd chain link 13.Further, the tip portion 15b of pin 15 gives prominence to more laterally than the outer side surface of another link plate 12 of formation the 2nd chain link 13.Then, in order to make pin 15 can not come off from the pin insertion hole 25 of link plate 12, and the tip portion 15b of pin 15 is riveted.
Now, pin 15 keeps in the mode freely can rotated relative to the both sides of the pin insertion hole 25 of the lining 14 be installed on the 1st chain link 13 and the 2nd chain link 13.Thus, the 1st chain link 13 is connected in the mode that can freely rotate relative to the 2nd chain link 13 by pin 15.Like this, by being connected in series by multiple chain link 13, thus chain 11 is completed.
Then, the effect of above-mentioned chain 11 is described.
Chain 11 is formed ring-type and is wound around not shown whelp and is used.Therefore, when whelp rotates, chain 11 stretches at the length direction X of chain 11, and advances to a direction.Such as, if by not shown multiple bucket to be installed at equal intervals on chain 11, the article such as coal or iron ore that can be used in being loaded into gravel car load and unload.
When such purposes uses eccentric chain 11, larger tensile force is applied to chain 11.In this case, because the intermediate portion 22 of the link plate 12 forming chain link 13 extends relative to length direction X, obliquely so stress easily concentrates on the intermediate portion 22 of link plate 12.
This point, according to the present embodiment, the thickness of the intermediate portion 22 of link plate 12 is greater than the thickness of the 1st end 20 and the 2nd end 21.Therefore, the intensity of the intermediate portion 22 of link plate 12 is higher than the intensity of the 1st end 20 and the 2nd end 21.Therefore, even if stress concentrates on the intermediate portion 22 of link plate 12, also can suppress the distortion of intermediate portion 22, thus suppress the distortion of link plate 12.Therefore, because the distortion of chain 11 is suppressed, so the durability of chain 11 improves.
If be set as by the thickness of link plate 12 comparatively large, the intensity of link plate 12 just can be improved.But, because the weight of link plate 12 increases, so the forward velocity of chain 11 is slack-off.This point, according to the present embodiment, is only set greater than the thickness of the 1st end 20 and the 2nd end 21, and forms porose 26 at intermediate portion 22 by the thickness of intermediate portion 22.Thereby, it is possible to the intensity maintaining intermediate portion 22 also can realize the lightweight of link plate 12.Therefore, it is possible to realize the light-weighted of chain 11 to maintain intensity simultaneously.
The lining patchhole 23 be formed on the 1st end 20 of link plate 12 is greater than the pin insertion hole 25 be formed on the 2nd end 21.Therefore, the situation of rigidity lower than the rigidity of the 2nd end 21 of the 1st end 20 is had.This point, according to the present embodiment, the periphery of the lining patchhole 23 of the 1st end 20 is formed with annular convex 24.Played a role as strengthening rib by annular convex 24, thus suppress the reduction of the rigidity of the 1st end 20.
Above, following effect can be obtained according to the present embodiment.
(1) when chain 11 advances, link plate 12 stretches at be rotated around direction, i.e. the length direction X of chain 11.In this case, stress easily concentrates on the intermediate portion 22 of the link plate 12 extended obliquely relative to length direction X.Therefore, the situation that intermediate portion 22 produces distortion is had.This point, according to the present embodiment, the thickness of the intermediate portion 22 of link plate 12 is greater than the thickness of the 1st end 20 and the 2nd end 21.Therefore, it is possible to the intensity settings of the intermediate portion 22 of link plate 12 to be become the intensity higher than the 1st end 20 and the 2nd end 21.Therefore, even if stress concentrates on the intermediate portion 22 of link plate 12, the distortion of intermediate portion 22 and link plate 12 can also be suppressed.
(2) when link plate 12 is stretched at the length direction X of chain 11, large relative to the intersecting angle of length direction X position, stress is more easily concentrated.This point, according to the present embodiment, intermediate portion 22 possesses the 1st cross part 22a and the 2nd cross part 22b.Further, the 1st cross part 22a is greater than the intersecting angle of the 2nd cross part 22b relative to the intersecting angle of the length direction X of chain 11.And the thickness of the 1st cross part 22a is greater than the thickness of the 2nd cross part 22b.Thus, even if link plate 12 stretches at the length direction X of chain 11 and makes stress concentrate on intermediate portion 22, the distortion of the 1st cross part 22a and the 2nd cross part 22b can also be suppressed.
(3) intermediate portion 22 is obtuse angle relative to the intersecting angle of the 1st end 20 and intermediate portion 22 relative to the crossing angle of the 2nd end 21.Therefore, as compared to the attachment portion of the 1st end 20 and intermediate portion 22 and the 2nd end 21 formation bending with the attachment portion of intermediate portion 22, link plate 12 intermediate portion 22 when length direction X stretches can be suppressed to produce and be out of shape.
(4) the circular annular convex 24 of being surrounded by lining patchhole 23 is formed in the 1st end 20 of link plate 12.Annular convex 24 is arranged on the periphery of lining patchhole 23, and gives prominence to laterally from the outer side surface 20a of link plate 12.In this case, because annular convex 24 plays a role as strengthening rib, so the intensity of the 1st end 20 of link plate 12 can be maintained.That is, the intensity reduction of the link plate 12 caused because of lining patchhole 23 can be strengthened by annular convex 24.
(5) only the thickness of intermediate portion 22 is formed as being greater than the 1st end 20 and the 2nd end 21, and forms porose 26 at intermediate portion 22.According to this formation, link plate 12 can be suppressed to be stretched at length direction X and the distortion caused, and the lightweight of link plate 12 can be realized.
Above-mentioned mode of execution also can change in such a way.
Also hole 26 can be omitted from link plate 12.
Be formed on the position in the hole 26 on link plate 12 except intermediate portion 22, also can be arranged near the 1st end 20 or near the 2nd end 21.Further, the size in hole 26 or shape also can suitably change.
Also annular convex 24 can be omitted from link plate 12.
Also any one party the 1st cross part 22a and the 2nd cross part 22b can be omitted from the intermediate portion 22 of link plate 12.
Also the intermediate portion 22 of link plate 12 can be made to bend to the 2nd end 21 from the 1st end 20.In this case, also intermediate portion 22 can be formed as, along with from the 1st end 20 near the 2nd end 21, the less thick of intermediate portion 22.
The intermediate portion 22 of link plate 12 also can be formed as extending towards the direction orthogonal with length direction X.That is, also link plate 12 can be formed as crank-like, intersect with the 1st end 20 and the 2nd end 21 to make intermediate portion 22.
Intermediate portion 22 also can be set as acute angle relative to the intersecting angle of the 1st end 20 and intermediate portion 22 respectively relative to the intersecting angle of the 2nd end 21.
