In addition, the internal diameter of keeper 45 forms slightly greater than the state of two wires shape bodies 1 along axial overlap, and keeper 45 is designed to as the thread like body limiting part, its be used to limit suspended span this to the wire-like body 1 between the second spur gear 41a and the 41b along side shifting radially outward.As an example, the internal diameter of keeper 45 is 2.2 times of wire-like body 1 external diameter.
In addition, in lower house 22, be formed with recess 48a and 48b, and then expose the second spur gear 41a in the lower house 22 and core and near the part thereof of 41b along the top edge of side plate 22a and 22b.
In upper shell 23, on side plate 23a and another side plate 23b, be respectively arranged with travelling gear 51a and 51b, and these travelling gears 51a and 51b form respectively its 52a and 52b rotatably are supported on side plate 23a and the 23b by bearing 53a and 53b towards each other position.
These travelling gears 51a and 51b have first spur gear 54 and driven wheel of differential 55 respectively, and first spur gear 54 is designed to mesh with the second spur gear 41a, 41b.
In addition, the top board 23c of upper shell 23 is provided with and drives bevel gear 56, and this drives driven wheel of differential 55 engagements of bevel gear 56 and travelling gear 51a, 51b.This axle 57 that drives bevel gear 56 is subjected to rotatably supporting by the bearing 59 that is arranged on the top board 23c, and extend out to the upper surface side of top board 23c at axle 57, promptly is provided with handle 58 with the end that drives bevel gear 56 relative sides.In addition, by controlling and rotating this handle 58 and rotate driving bevel gear 56.In the present embodiment, driven wheel of differential 55 and driving bevel gear 56 are spiral bevel gear.
As an example, the number of teeth that drives bevel gear 56 is 20, the number of teeth that each bevel gear 55 of travelling gear 51a, 51b and the number of teeth of first spur gear 54 are respectively 40, the second spur gear 41a and 41b is respectively 24, and the number of teeth of idler gear 31a and 31b is respectively 12.In this case, when driving bevel gear 56 rotations during two weeks, travelling gear 51a and 51b rotate a circle.In addition, when travelling gear 51a and 51b rotation during 3 weeks, the second spur gear 41a and 41b rotated for 5 weeks.
Next, explanation is utilized above jockey 11 connect the method for wire-like body 1.
At first, both sides from jockey 11, the end 1a of wire-like body 1 is inserted in each joint-cutting 44 of the second spur gear 41a, 41b in the housing 21, and the end 1a of wire-like body 1 extends outward predetermined length by the second spur gear 41a that is positioned at opposite side, the through hole 43 of 41b.
Select as another kind, after the housing 21 from jockey 11 takes off the second spur gear 41a, 41b, wire-like body 1 is inserted in the gear, and then gear is arranged on the precalculated position in the housing 21 once more.
Under above-mentioned state, control the also handle 58 of revolving joint 11.Thereby, drive bevel gear 56 rotations, along with making travelling gear 51a and 51b, this rotation rotates in the opposite direction.In addition, the rotation of travelling gear 51a and 51b is delivered to second spur gear 41a and the 41b, and then the second spur gear 41a and 41b rotate in the opposite direction.
Thereby, stranded through hole 43 that passes the second spur gear 41a, 41b and joint-cutting 44 between the second spur gear 41a and 41b and the wire-like body 1 that is restricted.In this step and since stranded towards the coupling part 2 pulling wire-like bodies 1, and then produce the power of distance between reduction second spur gear 41a and the 41b; Yet, owing between the second spur gear 41a and 41b, be provided with keeper 45, make the second spur gear 41a and 41b maintain preposition, therefore can carry out stranded uniformly.
In addition, because keeper 45 is arranged on suspended span at the wire-like body 1 between the second spur gear 41a and the 41b radially near the position the outside, so when carrying out when stranded, can limit wire-like body 1 along side shifting radially outward.In other words, even when wire-like body 1 is tending towards crawling (or eccentric) in stranded process, wire-like body 1 contacts with the interior perimeter surface of keeper 45, by this contact resistance, can stably set wire-like body 1 along stranded axis (along the rotating shaft of the second spur gear 41a and 41b).Thereby wire-like body 1 can be evenly and securely stranded mutually.In addition, after carrying out pre-determined number stranded, the handle 58 that stops operating is stranded to stop.
Next, as shown in Figure 4, by wire-like body 1 being twisted together under the state that forms coupling part 2, be arranged in the jockey 11 as the terminal h1 of the heater H of electric heater unit and the end 1a that h2 is connected to wire-like body 1.Subsequently, by opening the switch of heater H, between terminal h1 and h2, supply electric current, because the resistance of coupling part 2 self, stranded part is heated to 250～500 ℃, is preferably about 400 ℃, and kept at least 10 seconds or the longer time, be preferably about 20 seconds to anneal.As a result, the diameter ratio of briquetting of coupling part 2 can reach about 100%.
Next, utilize hinge 24 to rotate upper shell 23, the top of opening lower house 22, thereby second spur gear 41a and the 41b in the taking-up lower house 22.
Move second spur gear 41a and the 41b along away from each other direction, and then from the through hole 43 of the second spur gear 41a and 41b, pull out the end 1a of wire-like body 1.In addition, from the joint-cutting 44 of the second spur gear 41a and 41b, further pull out wire-like body 1, thereby and pull out wire-like body 1 from the notch portion 46 of keeper 45 and take out keeper 45.
Subsequently, utilize pliers, plate shearing machine etc. to cut off the non-stranded part of the 2 extended end 1a from the coupling part.
As a result, wire-like body 1 twists together and owing to the plastic deformation of stranded coupling part 2 is combined as a whole equably at its end 1a, thereby can obtain firm connection status.
In addition, under the situation of after stranded, not annealing, utilize watery fusion soft metal 12 also can be fastenedly connected part 2 as shown in Figure 2.Thereby, can prevent the backtwisting of coupling part 2, can obtain firm connection status in addition.
As mentioned above, according to present embodiment, near the maintaining part that part forms by through hole 43 and joint-cutting 44 by the second spur gear 41a, 41b the end 1a of wire-like body 1 is assigned to maintenance and suspended span between the second spur gear 41a, 41b, thereby, and relatively rotate second spur gear 41a and the 41b along opposite direction respectively along axially overlapped.As a result, between the second spur gear 41a and 41b, can wire-like body 1 be twisted together equably and plastic deformation takes place with low cost, thereby can connect securely.
In addition, because the through hole 43 of the second spur gear 41a, 41b and joint-cutting 44 as the retaining part of wire-like body 1, therefore by wire-like body 1 is inserted in the joint-cutting 44, can utilize the retaining part that is formed by joint-cutting 44 easily to keep wire-like body 1.In addition, when wire-like body 1 being inserted when keeping wire-like body 1 in the through hole 43, when wire-like body 1 twists together, can stably keep the periphery of wire-like body 1, and can further carry out stranded uniformly by the interior week of through hole 43.
In addition, keeper 45 is as the thread like body limiting part, the restriction suspended span at the wire-like body 1 between a pair of rotary body under the state of side shifting radially outward, wire-like body 1 twists together.Therefore, can stably set wire-like body 1, and wire-like body 1 can twist together evenly and securely when avoiding mobile astatically and swing along stranded axis.
In addition, by utilizing heater H between the end 1a that wire-like body 1 is twisted together formed coupling part 2, to supply electric current, the coupling part 2 that is arranged in jockey be heated to 250～500 ℃ temperature and kept 10 seconds or the longer time to anneal.As a result, utilize the simple heating device to make the diameter ratio of briquetting of coupling part 2 reach about 100%, thereby can increase the contact resistance of coupling part.
In addition, because the jockey 11 that wire-like body 1 is linked together has the simple structure of not using special entity etc., therefore can reduce equipment cost significantly.In addition,, therefore can reduce the quantity of assembly because thread like body limiting part and keeper 45 form parts, and can the simplification device structure.In addition, also keeper 45 and thread like body limiting part can be set separately.
Especially, owing between the set tooth of the outer circumferential side of the second spur gear 41a, 41b, open wide as the joint-cutting 44 of the retaining part that keeps wire-like body 1, wherein these teeth will with the tooth engagement of first spur gear 54 of travelling gear 51a, 51b, therefore compare with the situation that joint-cutting is formed on the tooth position, the tooth of the second spur gear 41a, 41b can mesh reliably with the tooth of first spur gear 54.In addition, can suppress the tooth life-span shorten and from the transmission of power deficiency of travelling gear 51a, 51b.
Have first spur gear 54 that is combined as a whole and travelling gear 51a, the 51b of driven wheel of differential 55 respectively owing to use, therefore can realize the minimizing of component count and the simplification of structure, can realize that in addition cost reduces.
In addition, because the opposite side at travelling gear 51a, 51b is provided with a pair of idler gear 31a and 31b, and thereby this rotatably supports the second spur gear 41a, 41b to idler gear 31a, 31b and the second spur gear 41a, 41b engagement, therefore by idler gear 31a, 31b together with travelling gear 51a, 51b, can rotatable and removably support the second spur gear 41a, 41b and needn't use bearing etc.
In addition, owing to be provided with the keeper 45 with predetermined length between the second spur gear 41a and 41b, wire-like body 1 that therefore can stranded predetermined length can further carry out stranded to connect in addition equably.
In addition,, therefore can suppress the backtwisting of wire-like body 1, can further increase the contact resistance of coupling part 2 in addition because 2 places utilize watery fusion soft metal 12 that wire-like body 1 is tightened together in the coupling part.
In the present embodiment, although by means of example the wire-like body 1 interconnective situation that is formed by solid wire respectively has been described, also can use respectively will interconnective wire-like body 1 by the formed twisted wire conduct of stranded many lines.Direction of lay when preferably end 1a being interconnected in these cases, is set at consistent with the direction of lay of solid wire.Thereby, stranded mutually when connecting when wire-like body 1, further carry out two strands of stranded cablings, therefore can keep the connection status that obtains by stranded reliably.
In addition, in advance stranded carry out with the many wires shape body 1 that connects stranded with the situation that forms twisted wire under, the direction of lay that the direction of lay when preferably end 1a being interconnected is set at when forming twisted wire is consistent.Thereby, when many wires shape body 1 is twisted together, can keep the state of the coupling part 2 of wire-like body 1 reliably.
In addition, as above-mentioned method of attachment, although by means of example the interconnective situation of end 1a with pair of metal thread like body 1 has been described, even when wire-like body 1 has annular, said method can certainly be applied to connect two end 1a of wire-like body 1.
In addition, simultaneously it is being carried out in the stranded endless metal cord that forms by wire-like body 1 being bent to annular, when two ends with a wires shape body 1 interconnect, the wire-like body 1 that utilizes a plurality of pins that not needing except wire-like body 1 to be connected connected carries out fastener, and these pins move towards the direction away from wire-like body 1 to be connected.Thereby, preferably under wire-like body 1 to be connected is positioned at locational state away from the wire-like body 1 that does not need to connect, connect.
Next, with reference to Fig. 5～7 explanations, second preferred embodiment of the present invention.
Shown in Fig. 5 (a), the end 6 of the end 5 of main line 3 and branch line 47 interconnects in the coupling part in wire-like body 10, wherein main line 3 is served as reasons and is had the baseline that the macrocyclic little twist of long wave (twist) twisted becomes, and branch line 4 is for being twisted into the wrap wire of wavelength period than the big twist of main line 3 weak points with main line 3.At these 7 places, coupling part, main line 3 twists together with branch line 4, and carry out stranded simultaneously like this: promptly, branch line 4 is wrapped in around the main line 3.In the twisting part office, plastic deformation takes place with branch line 4 and links together securely owing to the frictional force that is produced therebetween in main line 3 mutually.
In addition, shown in Fig. 5 (b), form after the sweep 5a in the end 5 of the channeling direction side that is positioned at coupling part 7 towards the direction bending metals wire body 10 opposite with the channeling direction side, removing unnecessary length part by cutting, to stay length be that a part of end 5 of 3～10mm is as being bent to form part, and this wire-like body 10 is guided to the route (direction shown in the arrow in the figure) of next technology as intermediate products, in these cases, can prevent reliably when cutting off end 5 when blocking something and producing the excessive load that is applied on it and cut off the problem of coupling part 7.
In addition, in wire- like body 10,7 places tighten together main line 3 and branch line 4 in the coupling part to utilize watery fusion soft metal 8.As watery fusion soft metal 8, for example can preferably use copper-ashbury metal (scolder).In Fig. 5, utilize watery fusion soft metal 8 according to its wetability and the stranded main line 3 of soldering and each boundary member between the branch line 4, thereby main line 3 and branch line 4 are tightened together; Yet, also can utilize watery fusion soft metal 8 to cover entire connection portion 7 and carry out fastening.
As mentioned above owing to utilize watery fusion soft metal 8 to make main line 3 and branch line 4 secured to one another, therefore can suppress main line 3 and branch line 4 in the coupling part 7 place's backtwistings, in addition, can increase the contact resistance of coupling part 7.In addition, as the fixative that is used for main line 3 and branch line 4, also can use adhesive to replace watery fusion soft metal 8.
Next, with reference to Fig. 6 and Fig. 7 the jockey that is used to make wire-like body 10 is described.
As shown in Figure 6 and Figure 7, this jockey 60 mainly comprise housing 61, drive bevel gear 62, a pair of driven wheel of differential 63 and 64, a pair of plectane 65 and 66, as first spur gear 67 and 68 of a pair of first rotary body, as a pair of second spur gear 69 and 70 and two pairs of idler gears 71 and 72 as the idle running rotary bodies with second rotary body of minor diameter.In addition, in the present embodiment, driving bevel gear 62 is straight bevel gear with driven wheel of differential 63,64.
In driving bevel gear 62, axle 76 rotatably is supported on the top board 78 of upper shell 74 by bearing 77.The handle 79 that is arranged on axle 76 ends by rotation rotates driving bevel gear 62.The number of teeth that drives bevel gear 62 for example is 20 (20T).Drive bevel gear 62 and driven wheel of differential 63,64 engagements.
Driven wheel of differential 63,64 has the axle 80,81 vertical with the axle 76 that drives bevel gear 62 respectively, axle 80 wherein rotatably is supported on the side plate 83 of upper shell 74 by bearing 82, and another root axle 81 rotatably is supported on another side plate 85 of upper shell 74 by bearing 84.The number of teeth of driven wheel of differential 63,64 for example is respectively 40 (40T).
Near second spur gear, 69,70 each center eccentric position place, diameter forms one type retaining part slightly greater than the through hole 86 of branch line 4, and this through hole 86 is designed to allow branch line 4 to pass therethrough.
In addition, in each second spur gear 69,70, forms joint-cutting 87 as the retaining part of another kind of type by the position cutting as the joint-cutting bottom of microbit in the pivot outside of being omitted, this joint-cutting 87 is unlimited between the tooth of the periphery that is arranged on above each second spur gear.The width dimensions of joint-cutting 87 is slightly greater than the diameter of main line 3, and is designed to and can main line 3 be inserted wherein from the opening portion that is arranged on outer circumferential side.In addition, although forming it, this joint-cutting 87 is positioned near the part in bottom deflection certain angle slightly, but can change this yawing moment by the direction of lay when connecting, and this yawing moment forms near the main line 3 that inserts the bottom is not easy to along side shifting radially outward.That is to say, be designed so that main line 3 can easily remain on the bottom of joint-cutting 87.In this case, the offset of the pivot of joint-cutting 87 bottom centre distance second spur gear 69,70 is less than the offset of the pivot of centre-to-centre spacing second spur gear 69,70 of through hole 86.
Top edge along the biside plate 88,89 of lower house 73 forms recess 90,91, through hole 86, joint-cutting 87 and near the position thereof of exposing second spur gear 69,70 by recess 90,91.
In addition, between second spur gear 69 and 70, be formed on the hollow cylindrical keeper 92 of the retaining part of conduct within the size of space L1, make that the pivot of keeper 92 is coaxial with second spur gear 69,70.This keeper 92 is formed with along axial notch portion 93 in the part of its circumference.
In addition, because the internal diameter of keeper 92 forms slightly greater than resulting size when main line 3 and branch line 4 band together, and keeper 92 is as the thread like body limiting part, its be used to limit suspended span this to the main line 3 between second spur gear 69 and 70 and branch line 4 along side shifting radially outward.The internal diameter of keeper 92 for example is 2.2 times of external diameter of main line 3 or branch line 4.
In idler gear 71 and 72, a pair of axle 96 and a pair of axle 97 rotatably are supported on the biside plate 88,89 of lower house 73 by bearing 98 and 99 respectively, and a pair of idler gear 71 and a pair of idler gear 72 (each between all be provided with at interval) respectively with 71,72 engagements of second spur gear.Because idler gear 71,72 numbers of teeth for example are respectively 12 (12T) and are arranged in the lower house 73, so idler gear 71,72 rotatably supports second spur gear 69,70.
Next, the method for attachment that explanation is utilized jockey 60 make wire-like body 10.
At first, thereby the upper shell 74 by opening jockey 60 or need not open upper shell 74 by the recess 90 of lower house 73 main line 3 is inserted in the joint-cutting 87 of second spur gear 69, and by the joint-cutting 87 of another second spur gear 70 predetermined length is pulled out in the end 5 of main line 3 via keeper 92.
Next, from a side opposite branch line 4 is inserted the joint-cutting 87 of another second spur gear 70, and by the joint-cutting 87 of second spur gear 69 predetermined length is pulled out in the end 6 of branch line 4 via keeper 92 with the channeling direction of main line 3.
Subsequently, apply revolving force to the handle 79 of jockey 60 and rotate this handle 79.Apply revolving force by hand or not shown power source.When handle 79 begins to rotate,, make driven wheel of differential 63 and 64 rotate in the opposite direction by this revolving force owing to drive bevel gear 62 rotations.In this step, the plectane 65,66 and first spur gear 67,68 are respectively along the direction rotation identical with driven wheel of differential 63,64, and second spur gear 69 and 70 rotates in the opposite direction.
Because second spur gear 69 and 70 rotates in the opposite direction, therefore main line 3 twisteds that pass through to another second spur gear 70 and be arranged on joint-cutting 87 bottoms from second spur gear 69 become to have the macrocyclic little twist of long wave, meanwhile, pass through to second spur gear 69 and the branch line 4 that is arranged on the through hole 86 becomes to have the macrocyclic big twist of shortwave around main line 3 twisteds from another second spur gear 70.In this step, be applied to tension force on the main line 3 owing to apply the roller adjustment, and branch line 4 is subjected to tension force owing to the resistance of keeper 92, so the tensile load ratio of main line 3 and branch line 4 is set in 10: 3～10: 6 the scope by not shown tension force.Thereby, by stranded make main line 3 and branch line 4 towards the coupling part 7 the pulling each other.
In this step, although act on the distance that shortens between second spur gear 69 and 70 effectively, owing to be provided with keeper 92 between second spur gear 69 and 70, therefore second spur gear 69 and 70 carries out stranded when maintaining the precalculated position.
In addition, because keeper 92 is arranged on suspended span at the main line 3 between second spur gear 69 and 70 and branch line 4 radially near the position the outside, so when carrying out when stranded, can limit main line 3 and branch line 4 along side shifting radially outward.In other words, even when main line 3 and branch line 4 are tending towards crawling (or eccentric) in stranded process, main line 3 contacts with the interior perimeter surface of keeper 92 with branch line 4, and, can stably set main line 3 and branch line 4 along stranded axis (along the rotating shaft of second spur gear 69 and 70) by this contact resistance.Thereby main line 3 and branch line 4 can be stranded mutually securely.In addition, after carrying out pre-determined number stranded, the handle 79 that stops operating is stranded to stop.
Next, as shown in Figure 7, form under the state of coupling part 7 at main line 3 and branch line 4 by stranded formation wire-like body 10, be arranged in the jockey 60 as on the terminal h1 of the heater H of electric heater unit and the end 5 and 6 that h2 is connected to wire-like body 10.Subsequently, by opening the switch of heater H, between terminal h1 and h2, supply electric current, because the resistance of coupling part 7 self, stranded part is heated to 250～500 ℃ and is preferably about 400 ℃, and kept at least 10 seconds or the longer time be preferably about 20 seconds to anneal.As a result, it is about 100% that the diameter ratio of briquetting of coupling part 7 can reach, and can increase the contact resistance of coupling part.
Next, open upper shell 74 from lower house 73, the opened upper end of lower house 73, and then the keeper 92 in the taking-up lower house 73 and the assembly of second spur gear 69,70 by hinge 75.
Take out stranded wire-like body 10 from the notch portion 93 of keeper 92 then.Subsequently, utilize pliers, plate shearing machine etc. to cut off the non-stranded part of from the coupling part 7 extended ends 5 and 6.As a result, the end 5 of wire- like body 10 and 6 is mutually stranded and 7 plastic deformations take place and be combined as a whole in the coupling part, thereby can obtain firm connection status.
In addition, under the situation of after stranded, not annealing, can utilize watery fusion soft metal 8 to be fastenedly connected part 7.Thereby, can suppress the backtwisting of coupling part 7, can increase the contact resistance of coupling part in addition, obtain firm connection status thus.
As mentioned above, according to present embodiment, part remains in the through hole 86 near the end of branch line 4, part is kept by joint-cutting 87 near the end of main line 3, main line 3 becomes near the part in its end along axially overlapped with branch line 4 suspended spans, and second spur gear 69 and 70 is respectively around the rotation relatively in opposite direction of the pivot between through hole 86 and the joint-cutting 87.As a result, between second spur gear 69 and 70,, can easily connect when branch line 4 is twisted into when being wrapped in around the main line 3, and the main line 3 that twists together like this and branch line 4 owing between generation frictional force and interconnect securely.In addition, owing to can be connected with 70, therefore can easily carry out attended operation with low cost by rotating second rotary body 69 simply in opposite direction with through hole 86 and joint-cutting 87.
In addition, since the restriction suspended span at the main line 3 between a pair of second rotary body 69 and 70 and branch line 4 under the state of side shifting radially outward, branch line 4 is stranded around main line 3, therefore can stably set main line 3 and branch line 4 along stranded rotation, and main line 3 and branch line 4 can avoid moving astatically and swing in twist together securely.In this step, because main line 3 is arranged on than branch line 4 more on the position near pivot one side, therefore main line 3 and branch line 4 was both inhomogeneous overlapped also unequally, twisted and stranded, and connect like this: promptly, branch line 4 is wrapped in around the main line 3 of twisted.Thereby the intensity that can suppress coupling part 7 reduces.That is to say, can bear tensile strength as the main line 3 of center line, and can bear the slip resistance energy as the branch line 4 of side line.
In addition, because the tensile load ratio of main line 3 and branch line 4 can be set in 10: 3～10: 6 the scope, so branch line 4 can be stranded more reliably around the main line 3 of twisted.
In addition, by between the end 5 and 6 of the stranded coupling part 7 of wire-like body 10, supplying electric current from heater H, the coupling part 7 that is arranged in jockey be heated to 250～500 ℃ temperature and kept 10 seconds or the longer time to anneal.As a result, utilize the simple heating device to make the diameter ratio of briquetting of coupling part 7 reach about 100%, thereby can increase the contact resistance of coupling part.
In addition, by main line 3 is inserted in the joint-cutting 87, can utilize the retaining part that forms by joint-cutting 87 easily to keep main line 3.In addition, after main line 3 and branch line 4 interconnect, can from joint-cutting 87, easily take out wire-like body 10.
In addition, because another retaining part is formed by through hole 86, therefore when when branch line 4 being passed through hole 86 keep branch line 4, the periphery that keeps branch line 4 interior week by through hole 86 when main line 3 and branch line 4 twist together, and can carry out stranded more reliably in 7 places in the coupling part.
In addition, 7 place's main lines 3 and branch line 4 can be stranded mutually securely by plastic deformation in the coupling part, thereby can obtain good connection status.In addition, backtwisting takes place in 7 places in the coupling part with branch line 4 can to suppress main line 3, and can further improve the intensity of coupling part 7.In addition, need not stay unnecessary length part, main line 3 and branch line 4 also can be in connection status.
In addition, under the state of the route that wire-like body 10 is guided to next technology as intermediate products, can prevent such problem reliably: promptly, cut off coupling part 7 when end 5 is blocked something and produced the excessive load that is applied on it when cutting off.
In addition, main line 3 remains in the joint-cutting 87.Thereby, can easily main line 3 be inserted in the joint-cutting 87, and can assign to keep wire-like body 10 by the maintaining part that forms by joint-cutting 87.
In addition, owing to be provided with the heater H that only heats coupling part 7,, also can comprise the technology of annealing although therefore the wire-like body is in the jockey 60.
