Similar with 120 to chain 10 respectively with 110 spherical parts 20, the spherical parts of chain 210 220 allow center link 214 along spherical parts 220 by the slide joint of sunk surface 214b pivoting action.This to chain 210 provide bigger flexible and allow chain on transmission path by more sharp-pointed vertical curve, and not in conjunction with the joint of chain link or chain.Chain 210 provides does not so partly have rivet-half bolt pin, and it can turn more sharp-pointed vertical turn and/or turn circle around different axles.Spherical parts and the corresponding sunk surface that forms so can distributed loads on constant skin area, reduce or eliminate stress substantially concentrated, when conventional chains by vertical bank or slope described stress concentration typically takes place with the joint when continuous.Spherical parts and sunk surface connect and also can be used in distributed load between chain link and stud bolt or pin on the skin area bigger than conventional chains.This reduced the wearing and tearing on bolt and the chain link and need still less maintenance and to chain and the life cycle of Yan Gengda.
Although shown head with rectangular shape, threaded pin of the present invention can have rounded nose (not being presented in Fig. 9 and 10), described rounded nose can be placed in usually on the side chain joint of flat or depression, allow the rotation of threaded pin opposite side and center link thus, and do not influence scope of the present invention.
Referring now to Figure 11-13, chain or portion of chain 310 comprise 315,312 and center link 314 of a pair of side chain joint.Center link 314 remains on side chain by threaded or bolt pin 316 and saves between 315,312, and described bolt pin 316 extends and keeps therein by the central area 314a of center link 314 with by opening 313 extensions in opening 315a in the side chain joint 315 and the side chain joint 312 and by cooresponding connecting element or nut 318.Threaded pin 316 comprises the spherical or annular spherical parts 320 of the mid point that is placed in threaded pin 316 usually or zone line.Similar in chain 10, chain 310 comprises around be connected to each other with ring-shaped continuous together a plurality of connections of transmission system, in known technology.For the comfort feature of explanation, to have only one group of chain to connect and be shown and describe herein, connection in addition is basic identical.
Threaded pin 316 comprises core or shaft portion 316a, threaded section or end 316b at the end of axial region 316a, has head 316c at the other end of shaft portion 316a.Threaded section 316b has the diameter narrower than axial region 316a, like this end of axial region 316a connecting element be secured on the threaded pin 316 or the inboard that is used for opposite side chain link 312 in abutting connection with the time be provided for abutment surface 316d in abutting connection with connecting element or nut 318 when chain is assembled, between the side chain joint, to keep the space.Head 316c can comprise that hexagon-head etc. is used for conveniently preventing the bolt rotation, and connecting element 318 is fixed on it simultaneously.
As seen, the head 316c of threaded pin 316 is rounded nose normally from Figure 11-13.Side chain joint 315 comprises a pair of trough of belt opening 315a, described trough of belt opening 315a comprises bigger to inner opening 315b, its size can be adjusted to hold head 316c by it, to make things convenient for the consolidation of chain link, and the outside opening 315c of minor diameter more, described outside opening 315c is littler of to keep head 316c therein than the diameter of head 316c.Littler opening 315c limits the trough of belt zone that narrows down adjacent to bigger opening 315b, to allow axial region 316a to slide along the trough of belt zone to settle head 316c at littler outside opening 315c, head 316c remains among the littler opening 315c thus, following discussion like that.Alternatively, side chain joint 315 can comprise to side chain and save 312 similar annular opening or passages, because threaded section 316b and axial region 316a can insert such hole or opening with the assembling portion of chain.
And side chain joint 315 centers on littler opening 315c in each end to small part and comprises that a sunk area or a bag 315d are used for being used to settle at each end the head 316c of threaded pin 316 when chain is assembled.The bottom of head 316c or fitting surface (Figure 13) are preferably crooked or circular, and sunk area 315d is formed to connect uniformly usually between fitting surface 316d that head 316c is provided and the sunk area 315d and to cooperate by correspondence simultaneously.Corresponding fitting surface that forms and sunk area make and can steadily rotate substantially between described pin 316 and the chain link 315, like this strap bolt pin 316 can opposite side chain link 315,312 and center link 314 rotate freely during at chain along its transmission path.
Center link 314 can be similar substantially to above-mentioned center link substantially, and can comprise elliptical shape or in each end of center link limits opening 314a and has the extension ring of circle or concave surface 314b be used for dividing in the middle hold spherical parts 320 with chain when transmission path moves in spherical parts 320 maintenance center link 314.
Similar with chain to above-mentioned spherical parts, the spherical parts of chain 310 320 allows center link 314 to reduce pivoting action by sunk surface 314b along the slide joint of spherical parts 320.This to chain 310 provide bigger flexible and allow chain in transmission path by more sharp-pointed vertical curve and not in conjunction with the chain link or the joint of chain.Chain 310 provides does not so partly have rivet-half bolt pin, and it can turn more sharp-pointed vertical turn and/or turn circle around different axles.Spherical parts and the corresponding sunk surface that forms so can distributed loads on constant skin area, reduce or eliminate stress substantially concentrated, when conventional chains by vertical bank or slope described stress concentration typically takes place with the joint when continuous.Spherical parts and sunk surface connect and also can be used in distributed load between chain link and stud bolt or pin on the skin area bigger than conventional chains.This reduced the wearing and tearing on bolt and the chain link and need still less maintenance and to chain and the life cycle of Yan Gengda.
The axle 316a that spherical parts 320 can loosely slides into threaded pin 316 goes up and is allowed to slide and rotation along axle 316a, perhaps can pressure fitted or the basic 316a of axle relatively fix, and do not influence scope of the present invention.Alternatively, spherical parts 320 can slide on the axial region 316a by loosely, and can comprise along and keep spherical parts 320 around the hollow disconnector ring or the sleeve (in 321 shown like that) of axial region 316a on one of spherical parts 320 or both sides with central area such as Figure 13 at the axial region 316a of pin 316.Disconnector-ball-cyclone separator arrangement or assembly can form single part or can the time separating component (two disconnectors and a spherical parts spare) that on axial region 316a, slides, and do not influence scope of the present invention.By with disconnector-ball-cyclone separator arrangement as single structure, the assembling of bolt and the maintenance of worn-out surface/spherical parts spare or replacement (if desired) can be simplified substantially.
As for bolt pin 116 ' as mentioned above, such disconnector-ball-cyclone separator arrangement helps to keep spherical parts in the central area of the axle of pin, allows spherical parts to center on described axle simultaneously and reduces to rotate freely motion.This helps to allow spherical parts and depression 314b align in center link 314 when chain is crooked and mobile along its transmission path.Disconnector-ball-cyclone separator arrangement also provides lower-cost replacement to the wearing part of pin, because disconnector-ball-separator assembly can reduce to replace under the situation of not replacing whole pin.Nut can be removed, disconnector-ball-cyclone separator arrangement (preferably single structure) bolt that can slip away, and under the situation of not replacing whole bolt pin, replace, provide new worn-out surface (new spherical parts) to bolt pin thus.This can provide significant cost savings, especially in pin can the application by corrosion-resistant steel or other expensive material manufacture, alternative costs in these are used than higher.
With reference to Figure 14 and 15, chain or portion of chain 310 ' comprise 315,312 and center link 314 ' of a pair of side chain joint.Center link 314 ' remains on side chain by threaded or bolt pin 316 ' and saves between 315,312, and described bolt pin 316 ' extends and keeps therein by the central area 314a ' of center link 314 ' with by opening 313 extensions in opening 315a in the side chain joint 315 and the side chain joint 312 and by cooresponding connecting element or nut 318.Threaded pin 316 ' comprises common cylindrical axial region 316a ', and center link 314 ' comprises non-sunk surface 314b ' flat or crooked, that be used to cooperate axial region 316a ' usually simultaneously.Chain 310 ' can be similar substantially to chain 310, as mentioned above, just do not repeat to go through so herein.Head 316c ' can comprise bending or circular fitting surface 316d ', and side chain joint 315 can be included in the fitting surface 315d that the correspondence on the littler trough of belt opening 315c forms simultaneously, as mentioned above, and with the smooth rotation of convenient pin 316 ' relative chain link.Alternatively, threaded pin 316 ' can comprise the cylindrical sleeve part (demonstration in Figure 14 and 15) that forms or center on axial region 316a ' and settle, as mentioned above.
In addition, can further predict cup head pin can be provided with round end and on the axial region between head or the head spherical parts is set at each end of pin.Head in can the inserting side chain link the amplification circular open and outwards slide into the opening that narrows down towards the end of side chain joint.The opening that narrows down has been got rid of round end substantially and has been moved therein, and offside chain link and the pin maintenance side chain of going like this saves.The side chain joint can comprise that the sunk area that centers on the opening that narrows down is to hold the longitudinal movement of round end with the amplification opening of basic eliminating pin opposite side chain link in the side chain joint therein.Like this, described pin is allowed to the rotation of opposite side chain link and center link, allows bigger flexible and than the wearing and tearing of gimmal simultaneously.
For example, with reference to Figure 16-18, chain or portion of chain 110 comprise a pair of side chain joint 412a, 412b and a center link 414.Center link 414 remains between the corresponding end of side chain joint 412a, 412b by bolt or the bolt pin 416 that extends by corresponding opening 413 and the central area 414a by center link 414.Opening 413 comprises bigger inwardly common circular open 413a and littler outwards circular usually groove or opening 413b.It is littler and bigger than the more small end opening 413b among each side chain joint 412a and the 412b than bigger opening 413a that each sells 416 head 416c, and will sell 416 and remain to side chain and save 412a, 412b and center link 414.Pin 416 comprises common sphere or annular spherical parts 420, and it is placed in mid point or the zone line of the axial region 416b of pin 416.Center link 414 can be similar to the center link of above-mentioned discussion substantially and can comprise be generally oval or each end has in the prolongation ring of circle or sunk surface 414b be used for part hold therein spherical parts 420 with chain when transmission path moves in spherical parts 420 maintenance center link 414.Similar to chain 10, chain 410 comprises a plurality of connections that link together with continuous annular around transmission system, as in the known technology.Easy for what illustrate, have only the part of chain or one group of connection to be shown and explanation herein, the other part of bonded assembly or other one group of connection are basic identical.
Pin 416 comprises core 416a and head 416c at each end of axial region 416a.Head 416c lower portion or fitting surface 416d (Figure 18) normally circular and that comprise band angle or bending, described fitting surface has the diameter bigger than axial region 416a from the such head 416c that radially outward extends that respectively holds of axial region 416a usually.
As seen, each side chain joint 412a, 412b comprise a pair of trough of belt opening 413 from Figure 16,17, and described trough of belt opening 413 sizes can be adjusted to hold a 416c by bigger to inner opening 413a, to make things convenient for the consolidation of chain.In case insert opening 413a, pin 416 and head 416c can outwards move up to axial region 416a for water jacket or opening 413b in.Head 416c can be placed in the bent recess part 413c on the outer at least opening 413b then, sell like this 416 and side chain joint 412a, 412b and center link 414 be fixed together usually.Corresponding head and the even cooperation between the side chain joint and pulsation-free rotation usually that forms with convenient pin of the common fitting surface 416d of bent recess part or regional 413c with head 416c.Because the fitting surface 416d of sunk part 413c and head 416c is normally circular and corresponding formation, pin 416 is allowed in chain opposite side chain link 412a, 412b rotation when its transmission path moves, with rectangular distribution wearing and tearing on pin 416 substantially, extended like this and sold life-span of 416.
Similar to other spherical parts of above-mentioned discussion, the spherical parts 420 of chain 410 passes through to allow along the bearing fit of the sunk surface 414b of spherical parts 420 pivoting action of center link 414.This to chain 410 provide bigger flexible and allow chain on transmission path by a more sharp-pointed vertical curve, and not in conjunction with the joint of chain link or chain.Chain 410 provides like this by more sharp-pointed vertical turn and/or around the pin of different axles by circle.Spherical parts and the corresponding sunk surface that forms so can distributed loads on constant skin area, reduce or eliminate stress substantially concentrated, when conventional chains by vertical bank or slope described stress concentration typically takes place with the joint when continuous.Spherical parts and sunk surface connect and also can be used in distributed load between chain link and pin on the skin area bigger than conventional chains.This reduced the wearing and tearing on bolt and the chain link and need still less maintenance and to chain and the life cycle of Yan Gengda.
Referring now to Figure 19 and 20, chain or portion of chain 410 ' comprise a pair of side chain joint 412a, 412b and a center link 414 '.Center link 414 ' remains between side chain joint 412a, the 412b by the central area 414a ' of center link 414 ' and the swivel pin 416 ' that extends by the opening 413 among each side chain joint 412a, 412b by extending.Pin 416 ' comprises cylinder axial region 416a ', and center link 414 ' comprises flat or non-sunk surface 414b ' usually simultaneously, is used to cooperate axial region 416a '.The head 416c ' of pin 416 ' comprises common circle and common circular fitting surface 416d ', and side chain joint 412a, 412b comprise that corresponding sunk area that forms or mating surfaces 413c are used to cooperate fitting surface 416d ' with the smooth rotation between convenient pin 416 ' and side chain joint 412a, the 412b simultaneously.Chain 410 ' can be similar to chain 410 substantially, as mentioned above, omits detailed discussion like this.Alternatively, pin 416 ' can comprise common formation or the cylindrical sleeve part (showing) of settling around axial region 416a ' in Figure 19 and 20, as mentioned above or as described below.
The head that it is also envisioned that the pin of portion of chain can be a non-circular shape, and the sunk part of one of side chain joint can be cooresponding non-circular shape at least, and head and pin can non-rotatably be fixed by the opposite side chain link like this.For example, the sunk area of head and side chain joint can be formed with two or more sides with to non-rotating joint is provided between head and the sunk area, allows head and bolt or pin manually to rotate to adjust or to change the worn-out surface cooperation of axle and spherical parts and center link simultaneously.For example, the pin of bolt pin or bolt part (axle and head) can ratchet be rotated or is rotated 60 degree or 90 degree or a certain amount of (according to the number of the side of head and sunk area) with new worn-out surface that axle and spherical parts are provided (cooperate the part of center link and wear and tear during crooked relative to each other and rotation at chain link).Of the present inventionly like this adjust and can stir pin design and provide the life-span to increase significantly pin, because spherical parts (perhaps disconnector-ball-separator assembly) can be replaced as required, and/or described pin can rotate alternatively to provide new worn-out surface as required, the whole life cycle of its can extend substantially pin or bolt pin.
About 60 or 90 or 120 degree etc. be crossed over or be covered to each worn-out surface can around described pin, described thus pin can rotate aequum as required so that six or four or three different worn-out surfaces or worn-out surface part to be provided around described pin, and the abrasion loss on each worn-out surface part of convenient like this control is controlled or the wearing in period amount.This is especially very useful in the application of (length of chain is fixing with very little dimension limit) when chain is accurate pitch design, and the undue wear in one or more pin can influence pitch, described pitch can cause described chain in conjunction with (if two such chains along extending each other, connect simultaneously or place some things) or negative effect chain or transport plane therebetween.The pin of such chain can be stirred or rotate then to provide new worn-out surface to each pin, effectively resets the original tolerance of described pin to them thus, so described chain is reset to the length of its original regulation.For example, each pin can be struck the second place or the 3rd position or any other position so that new worn-out surface is moved to abration position.In these cases, have only first pin or first group of pin can need to reset so that suitable adjustment to be provided.Alternatively, the degree of wear on pin or the axial region (perhaps worn-out surface) can be monitored or definite, and described pin can rotate alternatively with the wearing and tearing on the worn-out surface of limiting pin.It is also envisioned that each position on the head of pin or salient angle can be labeled or count to indicate which part worn-out surface selected or use.
For example, with reference to Figure 21 and 22, the opening 513b of pin 516 head 516c and side chain joint 512 can be non-circular, sells 516 like this and non-rotatably is placed in and the side chain joint 512 by chain or portion of chain 510.For example, head 516c can be sagging or have three or more sides or the non-circular shape of part 516e (three bendings and common equidimension side shown in Figure 21,22), the shape correspondence of sunk area 513c to be to hold head, the rotation that the fitting surface of the head 516c within the depression 513c in corresponding like this sunk area that forms or the side chain joint 512 has prevented to sell 516 opposite side chain links 512 substantially.For example, the sidewall at one or more side chain joint on the hole can be engaged in the rotation of the sidewall of cooresponding one or more side chain joint on the hole with basic eliminating pin opposite side chain link.Like this worn-out surface of axial region 516a and/or spherical parts 520 usually opposite side chain link 512 fix by the head 516c in the basic fixed depression 513c, the sunk surface 514b that has only the axle in a step and/or the relative center link 514 of spherical parts like this is in chain contact and wearing and tearing during along its transmission path.
When in each position (such as one in three positions at the embodiment shown in Figure 21 and 22, perhaps in six positions in the described embodiment of Figure 23-25, as described below, perhaps to one in any other number of the suitable position of such layout), described pin can chain link be non-rotatable relatively usually, and can between described position, optionally adjust worn-out surface with the relative chain link of axial region of adjusting pin, chain link provides the optional joint of worn-out surface part relatively thus.The specific abrasive surface that such layout allows to sell by wearing and tearing certain the time allows the wearing and tearing and the life cycle of the described pin of control and allows to control or manual or rotation alternatively from a worn-out surface to the other worn-out surface of pin of pin.Described pin of the present invention and side chain joint arranges the pin that can stir is provided, and described pin can be by hand or stirred alternatively or rotate to be provided new worn-out surface at first worn-out surface by opposite side chain link after the abundant wearing and tearing.Each the worn-out surface part of the pin during the convenient control of such structure is used or the time quantum of each worn-out surface.
Alternatively, with reference to Figure 23-25, the opening 513b ' of pin 516 ' head 516c ' and side chain joint 512 ' can be non-circular, sells 516 ' like this and non-rotatably is placed in and the side chain that passes through chain saves 512 ' or portion of chain 510 '.As shown in Figure 23-25, head 516c ' can be hexagonal configuration usually, and notch area 513c ' has got rid of the rotation of pin 516 ' opposite side chain link 512 ' in six positions substantially.The worn-out surface of axial region 516a ' and/or spherical parts 520 ' usually can the opposite side chain link 512 ' by fix at depression 513c ' internal fixation head 516c ' substantially, have only like this axle and/or spherical parts a part will chain during along its transmission path the sunk surface 514b of contact and relative center link 514 wear and tear.Worn-out surface can be adjusted or toggle it to the new orientation of the depression 513c ' of new surface to the opposite side chain link 512 ' by swivel pin 516 ' then, as mentioned above.
Alternatively,, chain or portion of chain 510 with reference to Figure 26-27 " can comprise pin 516 ", described pin 516 " can be included in common columniform axial region 516b " opposed end on shaping or protrusion or hexagonal configuration head 516c ".Center link 514 " comprise usually flat or crooked, non-sunk surface 514b ", be used to engage axial region 516b ".Pin 516 " and side chain save 512 ' can be similar to the pin 516 ' of above-mentioned discussion substantially, detailed like this.
