Embodiment
With reference to accompanying drawing preferred implementation of the present invention is described.Fig. 1 is the stereogram of formation of typically representing the major component of the power transmission chain that chain-type continuously variable transmission adopted that first embodiment of the invention relates to (below, abbreviate chain as).With reference to Fig. 1, chain 1 comprises: a plurality of link plates 2 of arranging on the width direction W of chain direction of advance X and chain; Be used to interconnect a plurality of chain pins 3 of these link plates 2; Than the also slightly short a plurality of fillets 4 of this chain pin 3.
Fig. 2 is the sectional drawing of the major component of expression chain 1 shown in Figure 1, is that expression is included in the position three groups of link plate groups of identical a plurality of link plates 2 respectively on the chain direction of advance X.Particularly, be the first link plate group 51, the second link plate group 52 and the 3rd link plate group 53.Fig. 3 is the sectional drawing of link plate 2, chain pin 3 and the fillet 4 of chain 1.As shown in Figures 2 and 3, each link plate 2 is included on the chain direction of advance X a pair of link end 5,6 side by side, is formed with through hole 7 respectively on link end 5,6.
Through hole 7 for the link end 6 of the through hole 7 of the link end 5 of the first link plate group's 51 link plate 2 and the second link plate group's 52 link plate 2, it also comes on the chain width direction W, and, and first and second link plate group 51,52 link plate 2 is interconnected by the slotting chain pin 3 that leads in these through holes 7.
For chain pin 3, it is inserted the through hole 7 that leads in link plate 2 to be pressed into chimeric status sometimes, thereby restriction is with respect to the relative rotation of link plate 2; Small gap is set sometimes, and is inserted to move about state chimeric and to lead to, thereby allow relative rotation with respect to link plate 2 in through hole 7.For chain pin 3, for example be pressed into the through hole 7 of the link end 5 of each link plate 2 that is embedded in the first link plate group 51, thereby restriction relatively rotates with respect to each link plate 2 of the first link plate group 51, and the through hole 7 of the link end 6 of each link plate 2 that is embedded in the second link plate group 52 of being moved about, thereby allow relative rotation with respect to each link plate 2 of the second link plate group 52.
Equally, the through hole 7 of the link end 5 of the second link plate group's 52 link plate 2, with the through hole 7 of the link end 6 of the 3rd link plate group's 53 link plate 2 and come on the chain width direction W, and interlink by inserting to lead in the chain pin 3, the second of these through holes 7 and the 3rd link plate group's 52,53 link plate 2.That is,, be pressed into the through hole 7 of the link end 5 of each link plate 2 that is embedded in the second link plate group 52 to chain pin 3, and the through hole 7 of the link end 6 of each link plate 2 that is embedded in the 3rd link plate group 53 of being moved about.
Though not shown in the figures, next the 3rd and the 4th link plate group's link plate 2 is interconnected,, thereby form annular as the integral body of chain 1 so successively with link plate 2 per two groups of connections.
The two ends of chain pin 3, outstanding from the link plate 2 at the two ends that are disposed at chain width direction W to chain width direction W, be provided with the power transmission face 8,9 of sheave face contact usefulness in the both ends of the surface of chain pin 3.Because chain pin 3 directly acts on transmission power by its power transmission face 8,9, (for example, the high-strength material that SUJ2) waits forms so for example use Bearing Steel.
On the other hand, fillet 4 is the clavas slightly short than chain pin 3 that form in order not contact with the sheave face.For fillet 4, be to be pressed into to be embedded in through hole 7 sometimes, thereby restriction is with respect to the relative rotation of link plate 2; Sometimes be that small gap is set, being moved about is embedded in through hole 7, thereby allows the relative rotation with respect to link plate 2.
For fillet 4, for example, the through hole 7 of the link end 5 of its each link plate 2 of being embedded in the first link plate group 51 of being moved about, thereby allow relative rotation with respect to each link plate 2 of the first link plate group 51, and it is pressed into the through hole 7 of the link end 6 of each link plate 2 that is embedded in the second link plate group 52, thereby restriction is with respect to the relative rotation of each link plate 2 of the second link plate group 52.
According to aforementioned formation, fillet 4 become can with inserted the chain pin 3 rolling sliding contacts lead in identical through hole 7 (comprising at least roll contact and sliding contact one of contact).Thus, the relatively link plate group of chain direction of advance X adjacency (in abutting connection with the link plate 2 of configuration each other) free bend ground connection each other, and the sheave face of chain pin 3 relative pulleys rotates hardly can reduce frictional loss and guarantees higher efficiency of transmission.
Fig. 4 is the sectional drawing along the II-II line of Fig. 2.With reference to Fig. 4, feature part as present embodiment is following point: on the width direction W of chain, link plate 2 in adjacency is provided with gap S each other, can prevent that thus the link plate 2 of adjacency is in contact with one another friction, and the reduction of the efficiency of transmission when preventing that chain 1 from driving.
Particularly, on the width direction W of chain, an opposed side of the link plate 2 of adjacency comprises a pair of opposed faces 10 respectively, is provided with gap S between this opposed faces 10.Thus, the chain pin 3 (with reference to Fig. 2) of chain pin 3 relative adjacency on chain direction of advance X can be only to move (twisting) with the corresponding amount of gap S on the width direction W of chain.And gap S is configured to make twisting amount maximum to reach for example 0.5mm～1mm.
Fig. 5 (a)～Fig. 5 (c) is respectively the sectional drawing of part of manufacture method that is used to illustrate the chain 1 of present embodiment.Chain 1 is for example made through following three steps, that is: make interval constraint parts 11 carry out stacked stacked step each other on the width direction W at chain between the link plate 2 in abutting connection with configuration; With chain pin 3 and 4 slotting leading to of fillet in these through holes 7 and with a plurality of link plate 2 interconnective Connection Steps; Interval constraint parts 11 are removed step from what aforementioned link plate 2 was removed each other.
That is, shown in Fig. 5 (a), the chain pin 3 of correspondence and fillet 4 are inserted in successively the through hole 7 of link end 5,6 of the correspondence of corresponding link plate 2.At this moment, make interval constraint parts 11 respectively between (clamping) between the opposed faces 10 of the link plate 2 of the correspondence of adjacency on the chain width direction W.
Thus, shown in Fig. 5 (b), will two groups of link plates 2 (for example, the first and second link plate group's 51,52 link plate 2) of adjacency on the chain direction of advance X across super-interval limiting part 11 laminated configuration on chain width direction W.
Aforementioned interval constraint parts 11 are the parts that are used between the link plate 2 of adjacency on the chain width direction W forming gap S, can be formed by the material that soluble material such as coating, starch, cellulose and carbon steel, alloyed steel etc. have a good tensile.
Next, interval constraint parts 11 are removed between the link plate 2 of correspondence.Concrete, under the occasion that interval constraint parts 11 are formed by aforementioned material with soluble, melt by adopting water, organic solvent, inorganic solvent equal solvent, interval constraint parts 11 are removed each other from the link plate 2 of adjacency.In addition, under the occasion that interval constraint parts 11 are formed by aforementioned material with good tensile,, interval constraint parts 11 are removed each other from the link plate 2 of adjacency by extracting interval constraint parts 11.Thus, shown in Fig. 5 (c), be manufactured on the chain 1 that is provided with gap S along the link plate 2 of the last adjacency of chain width direction W each other.
And, also can be in advance across interval constraint parts 11 a plurality of link plates 2 of laminated configuration on chain width direction W, then chain pin 3 and fillet 4 are inserted together the through hole 7 that leads in the link end 5,6 of the correspondence of those a plurality of link plates 2.
Based on afore-mentioned, chain 1 according to present embodiment, by between the link plate 2 of chain width direction W adjacency, gap S being set, can preventing that the link plate 2 along chain width direction W adjacency when chain 1 is crooked from contacting with each other and produce surface friction drag, and reduce this friction torque.Therefore, the power transfer efficiency that can suppress chain 1 reduces.
In addition, when making chain 1,, can easily form gap S thus as long as after the push operation of chain pin 3 and fillet 4, remove interval constraint parts 11.Moreover, by adjusting the thickness of interval constraint parts 11, the easily value of adjusting play S.
In aforementioned embodiments; when making chain 1; also can be in advance at least one face of a pair of opposed faces 10 of the link plate 2 of correspondence, handle and form tunicle by application; then after the push operation of chain pin 3 and fillet 4; adopt water, organic solvent, inorganic solvent equal solvent to remove this protection, thereby form gap S.
As shown in Figure 6, the insertion amount (insertion stroke) in the time of also can being inserted into through hole 7 by setting chain pin 3 and fillet 4 forms gap S.Under this occasion, adjust the stroke of not shown press machine, make link plate 2 be positioned at the assigned position (for example, the P position) on the chain width direction W, and chain pin 3 and fillet 4 are inserted in the through hole 7 of link end 5,6.
In aforementioned each mode of execution, also can make Fig. 7 (a)～Fig. 7 (c) synthetic resin members 12 shown in respectively between each other along the link plate 2 of chain width direction W adjacency.Synthetic resin members 12 can be formed by materials such as phenol, nylon, fluorine, and the opposed faces 10 of each link plate 2 that is covered.Synthetic resin members 12 can be surperficial all parts of each link plate 2 of lining shown in Fig. 7 (a), also can be the parts of a face that only are arranged on the opposed faces 10 of each link plate 2 shown in Fig. 7 (b), can also be the parts on two sides that are arranged on the opposed faces 10 of each link plate 2 shown in Fig. 7 (c).
Under this occasion, synthetic resin members 12 can be formed the form that the gap S with correspondence stops up fully, also can be that the form with the part of only stopping up gap S forms, thereby allow the twisting of chain pin 3.
Thus, can prevent reliably that the link plate 2 of adjacency on chain width direction W is in direct contact with one another, therefore, the power transfer efficiency that can suppress chain 1 more reliably reduces.
Fig. 8 is the sectional drawing of the attachment portion of the chain of representing that typically chain-type continuously variable transmission that second embodiment of the invention relates to is used.The main difference point of the present embodiment and first mode of execution is: by after Zinc phosphate is handled, implement that lubricated lining is handled and the lining material 13 that obtains by stearate, and by the be covered surface of link plate 2 of this lining material 13; In the link plate 2 of the lining material outer side surface of the link plate 2 that becomes this lining and adjacency on the chain width direction W mode of state of contact each other, the arrangement that on its thickness direction, superposes of a plurality of link plates 2.Identical with first mode of execution about other points so save explanation.
The surface of link plate 2 is by lining material 13 lining among the figure, this lining material 13 is after Zinc phosphate is handled lining, implements lubricated lining by stearate and handles and obtain.This lining material 13 is formed by following processing method, at first, material is formed definite shape that is:, and the heat treated link plate 2 that has carried out regulation is carried out degreasing.Secondly, this link plate 2 is immersed in the zinc phosphate treatment agent, and makes it form the lining material that Zinc phosphate was handled.Next, after this link plate 2 taken out from primer, it is immersed in is used for being lubricated the primer that lining is handled again by stearate.Then, after being taken out, this link plate 2 makes its drying from primer.Make on the almost whole surface of this link plate 2 with such method and to form this lining material 13.And the thickness setting with this lining material 13 is about 3 μ m in the present embodiment.
As previously mentioned, the link plate 2 of lining and the link plate 2 of adjacency on its chain width direction W are with the side superposed configuration as previously mentioned, and mutual lining material outer side surface 21 is in contact with one another in its part each other.So as shown in Figure 8, aforementioned lining material 13 is between the opposed faces 10 of the link plate 2 of adjacency.
The chain 1 that relates to according to the present embodiment that constitutes as previously mentioned, because the surface of link plate 2 is covered by lining material 13, so can be, but also link plate 2 surface of contact each other that lining material 13 can be connected between free bend ground at thickness direction with its side superposed configuration.Thus, even when under state, being assembled into this chain 1 with higher surface pressure stack, by this chain 1 crooked side surface of contact phase mutual friction each other that makes aforementioned link plate 2, wearing and tearing take place or peel off in aforementioned thus lining material 13, can reduce aforementioned link plate 2 surperficial contact pressure each other.In other words, even aforementioned link plate 2 is superposeed each other, also surperficial contact pressure can be controlled at proper state with higher surface pressure.Therefore, owing to can reduce the frictional force of this link plate 2 surface of contact each other, so also can reduce the bending moment of chain 1, the efficiency of transmission that its result can suppress chain 1 reduces.
The lining material 13 of the chain 1 of present embodiment has adopted after Zinc phosphate is handled, and implements the lubricated lining material that is covered and handles and obtain by stearate.After Zinc phosphate is handled, implement lubricated lining by stearate and handle this lining material that obtains and have following characteristic: be easy to wearing and tearing when being subjected to sliding friction, can obtain stable slip surface fast.Therefore, even in link plate 2 surface of contact each other that aforementioned free bend ground connects, lining material 13 can be worn easily by less number of bends, so that aforementioned link plate 2 forms the stable slip surface of bending sleekly each other.So,, can reduce this link plate 2 surperficial contact pressure each other fast by trial run chain 1.This lining material 13 is given lubricity by being handled by the lubricated lining of stearate, so can further reduce the frictional force of aforementioned link plate 2 surface of contact each other.
In addition, in the present embodiment, implement the lubricated lining material that is covered and handles and obtain by stearate, also can adopt for example manganese phosphate processing though lining material 13 has adopted in Zinc phosphate processing back.Because: also the lining material 13 with present embodiment is the same to handle the lining material that obtains by manganese phosphate, and the initial running-in characteristic for sliding friction in its rubbing surface is good, and its surface also has the characteristic that is easy to wear and tear.
In aforementioned embodiments, though be about 3 μ m with the thickness setting of lining material 13, as the scope of this thickness preferably between 2 μ m～20 μ m.Because, then surpassed allowed band as the design load of the width direction size of chain 1 if the thickness of lining material 13 is blocked up than aforementioned range.Have again,, the situation of link plate 2 surperficial contact pressure each other might take place fully to reduce if thin excessively than aforementioned range.
In aforementioned embodiments, though, also can be the lining material that is covered on any one surface at least in link plate 2 surface of contact each other of thickness direction stack and adjacency at the almost whole surface-coated lining material 13 of link plate 2.Even if because under this occasion, also can be with lining material 13 between surface of contact, so can obtain aforementioned effect.
As the lining material beyond aforementioned, preferably for example zinc-plated, zinc-plated, copper facing, coating, resin etc., be that carbon steel etc. is easier to wearing and tearing than the material of link plate 2, or the cohesion of the lining material material that is easy to peel off a little less than, and bear link plate 2 can keep the material of predetermined thickness when producing surface pressure.By being suitable for lining material with lubricity, can reduce the frictional force of link plate 2 surface of contact each other of stack better, further reduce the bending moment of chain 1.
Next, the manufacture method to the power transmission chain of present embodiment describes.The chain 1 of present embodiment is for example made through three following steps, that is: the lining step that the side of link plate 2 is covered by lining material 13; A plurality of link plates 2 are superposeed on thickness direction and be configured in locational link plate configuration step as the regulation of chain 1; With the chain pin 3 slotting Connection Steps that connect the link plate 2 of arrangement in through hole 7 that lead to.
At first, to link plate 2, after handling lining by Zinc phosphate, stearate is implemented lubricated lining and is handled the lining material 13 (with reference to Fig. 8) that obtains, with its surface-coated (lining step).
Fig. 9 is illustrated in the manufacture method of chain 1 of present embodiment, the ideograph of the mode when chain pin 3 is pressed into through hole 7 in link plate 2.Among the figure, on the upper surface 60a of the pallet 60 of chain assembling usefulness, the surface is by a plurality of link plates 2 of lining material 13 linings, so that the part of its side is configured (link plate configuration step) in the mode of its thickness direction (chain width direction W) and the last stack of length direction (chain direction of advance X).
On this pallet 60, with chain 1 in the identical spacing width of spacing width of chain pin 3, be provided with a plurality of holes 61.In this hole 61, be separately installed with the guide finger 62 that can move up at upper and lower.This guide finger 62 is only with outstanding vertically upward from the upper surface 60a of pallet 60 with the roughly the same size of the width dimensions of chain 1.And guide finger 62 constitutes: under the occasion of the effect of vertically downward power, can be received into the inside in hole 61.The cross section of this guide finger 62 forms: be inserted into when through hole 7, can determine the position of through hole 7 exactly, and can easily it be extracted insertion.
By guide finger 62 is inserted the through hole 7 that leads in link plate 2, can link plate 2 arrangements be remained on the upper surface 60a of pallet 60 with the state identical with the finishing stage of chain 1.That is,, these link plate 2 trial assemblies are fitted on the upper surface 60a of pallet 60 with as long as chain pin 3 and fillet 4 are inserted the logical mode that just becomes the finishing stage of chain 1.
