It is the tooth crest 13 face shape in the direction of the width in tapered to flank 13a, is curved surface at this
Shape.
Thus, facewidth W13(of tooth crest 13 i.e., width in the direction of the width) less than base portion
Facewidth W12 of 12.
Understanding with reference to Fig. 1, Fig. 2, Fig. 4, chain 100 possesses the multiple lids 103 as anti-delinking part,
It is used for preventing because abutting with connector flat board 150 and connector flat board 150 comes off from pin part 110.
For being respectively supported at 1 pair of connector flat board 150 of two supporting parts 115, lid 103 is arranged
1 to pin end 116.
Lid 103 covers pin end face 117, is fixed on pin end by the press-in as fixing means
116。
Understand with reference to Fig. 1, when assembling chain 100, first by the pin part of connecting piece unit 101
Each supporting part 115 of 110 is inserted in pin-and-hole 155, and the trip of each connector flat board 150 is embedded in supporting part
115。
It follows that lid 103 to be arranged on each pin end 116, connector flat board 150 is prevented
De-process.
Hereinafter, assembly and connection part unit 101 and 1 pair of connector flat board through same assembly process
The 150 mutual in the longitudinal direction chains 100 connected.
When producing chain tension on chain 100, pin part 110 by each junction surface 140 in phase
Region make chain tension act on plate part 120.
Now, tensile stress is produced at junction surface 140.
On the other hand, pin part 110 makes chain tension as the company of acting on by pressure in opposed area
Fitting flat board 150.
It follows that the effect of the embodiment constituted as previously mentioned is illustrated.
Chain 100 passes through 1 connecting piece unit 101 and 1 pair of connector flat board 150 at length direction
On alternately and flexibly connect and formed, and be wound around on the multiple sprocket wheels 10 constituting chain-wheel mechanism,
It is possible to transmit power between multiple sprocket wheels 10.
Connecting piece unit 101 is made up of with 1 pair of plate part 120 1 pair of pin part 110, flat part
Points 120 link 1 to pin part 110 at 1 pair of junction surface 140, and pin part 110 is by being positioned at relatively
The junction surface 140 in portion 111 makes chain tension act on plate part 120 as pulling force, and 1 to even
Fitting flat board 150 is bendably attached to pin across described 1 pair of plate part 120 in the direction of the width
Part 110.
Thus, make chain tension as draw in opposed area by junction surface 140 due to pin part 110
Power and act on plate part 120, therefore result from round pin part 110 at plate part 120
At junction surface 140, dispersion produces the tensile stress at position, prevents with opposed area and non-relative region
Boundary B (with reference to Fig. 4) centered by boundary portion A(with reference to Fig. 4) produce stress and concentrate.
Thus, the fatigue strength of the plate part 120 of connecting piece unit 101 improves such that it is able to carry
The durability of high connecting piece unit 101, and then the durability of chain 100 can be improved.
It addition, when assembling chain 100, for 1 pair of pin part 110 and 1 pair of plate part 120
In the single part i.e. connecting piece unit 101 of integration, owing to flexibly connecting 1, connector is put down
Plate 150, is therefore pressed into the existing chain phase in 1 pair of outer connector flat board with 1 pair of connecting pin
Ratio, the assembling of chain 100 becomes simplified as thus assembleability improves, it is possible to reduce cost.
It is additionally, since and is being connected with plate part 120 has connector flat board in the pin part 110 of one
150, therefore when connecting piece unit 101 and 1 pair of connector flat board 150 are attached, with need
The existing chain wanting connecting pin and lining is compared number of components and is reduced, and also is able in this reduce
Cost.
It is formed with the 1st engagement space S 1 the most alternately and engages space S 2 with the 2nd, the 1st
1 pair of counterpart 111 of engagement space S 1 connected piece unit 101 and 1 pair of plate part 120 institute
Around, the 2nd engagement space S 2 is by the most adjacent connecting piece unit 101 each other non-
Counterpart 112 and the 1 pair of connector flat board 150 institute around, multiple sprockets 11 of sprocket wheel 10 can divide
Sequentially enter the 1st, the 2nd engagement space S 1, S2 the most one by one.
Thus, when chain 100 engages with sprocket wheel 10, rotated by sprocket wheel 10, thus sprocket
11 enter the 1st, the 2nd engagement space S 1, S2, carry out power between sprocket wheel 10 and chain 100
During transmission, it is by connector list owing to the power between sprocket 11 is delivered on chain 100
Unit 101 is carried out, and pin part 110 and plate part 120 are bonded into not separated, about pin part 110
And plate part 120, will not because there is gap between these pin part 110 and plate parts 120 and
Produce relative movement, therefore can prevent from producing noise due to described relative movement, it is possible to increase chain
The solemnly silent performance of 100.
Plate part 120 is only positioned between 1 pair of counterpart 111 in the longitudinal direction, junction surface 140
1 pair of counterpart 111 it is only positioned in pin part 110.
Thus, outside the 1 pair of counterpart 111 being not present on length direction due to plate part 120
The region of side i.e. non-relative region or the 2nd engagement space S 2, even if therefore pin part 110 is opened because of chain
Power and produce bending, it is also possible to avoid occurring when plate part 120 is present in non-relative region
The contacting, so contact noise, abrasion and frictional resistance subtract of plate part 120 and sprocket 11
Little, it is possible to increase the solemnly silent performance of chain 100, durability and power transmission performance.
And, there is not plate part 120 at non-relative region, correspondingly due to plate part 120
It is miniaturized in the longitudinal direction, therefore, it is possible to make plate part 120 lightweight, and then chain can be made
Bar 100 lightweight.
Due on the medial surface 121 of plate part 120, at sprocket wheel side Ri, to retreat face 124 relative
In widthwise central face Pw in more distally retreating compared with central crossbar portion 122 in the direction of the width
Face shape, therefore when being in the engagement of the 1st engagement space S 1 inner sprocket 10 and chain 100,
Even if there is the width position deviation i.e. width of chain 100 between sprocket 11 and chain 100
The width center Ps(of degree center, direction Pc and sprocket 511 is with reference to Fig. 4)
Occur on width to deviate and chain 100 is relatively close in the direction of the width relative to sprocket 11,
The medial surface 121 of plate part 120 is retreating at face 124 with the width side from widthwise central face Pw
Become big mode compared with central crossbar portion 122 to distance to retreat in the direction of the width, so can avoid
Sprocket 11 and medial surface 121 phase mutual friction.
Thus, due to the abrasion of plate part 120, contact noise and the chain of this phase mutual friction of cause
The gear teeth 11 are all lowered with the friction of plate part 120, the flat board therefore caused by suppression abrasion
The intensity of part 120 reduces such that it is able to improves the durability of plate part 120, and then can carry
The durability of high chain 100, it is possible to improve the solemnly silent performance of chain 100 by reducing contact noise,
Power loss when being additionally, since the reduction of friction and be in engagement reduces, it is possible to increase chain
The power transmission performance of 100.
Further, since avoid the sprocket 11 being in engagement and medial surface 121 phase mutual friction
Structure is arranged on medial surface 121 as retrogressing face 124, therefore can lead on sprocket 11
Cross reduction for avoiding tapering (or narrow width) degree of tooth crest 13 of this phase mutual friction, formation
Scope increases facewidth W13 of tooth crest 13, it is possible to improve the intensity of sprocket 11.
Owing to plate height H2 of the plate part 120 at sprocket wheel side Ri is less than sprocket wheel side Ri's
Plate height H5 of connector flat board 150, is therefore connected by the face of retrogressing 124 at plate part 120
Plate height H2 of edge 129 defined is less compared with plate height H5 of connector flat board 150,
Correspondingly avoid the phase mutual friction of sprocket 11 and medial surface 121, therefore, it is possible to reduce flat further
The abrasion of plate part 120, contact noise and sprocket 11 and the friction of plate part 120.
Owing to retreating the width section configuration in face 124 in the direction of the width towards widthwise central face
Pw is convex shape, and, along with in the height direction from height center face Ph near sprocket wheel side Ri
Edge 129, the arc-shaped increased continuously in the width distance from widthwise central face Pw.
Thus, due to along with in the height direction from central authorities side 123 near the edge of sprocket wheel side Ri
129, retreat the width section configuration in face 124 in the width distance from widthwise central face Pw
The arc-shaped increased continuously, is therefore guided and at width by retrogressing face 124 at sprocket 11
Upper mobile time, relative to the ratio of the width amount of movement of short transverse amount of movement, retreating face 124
On the contact site of sprocket 11 then become the biggest the closer to edge 129.
Thus, owing to entering the sprocket 11 of the 1st engagement space S 1 described in retreat on face 124
Contact site is more corrected in early days the closer to the deviation of edge 129 then width position, therefore promotes
Avoid when follow-up sprocket 11 enters follow-up 1st engagement space S 1 with medial surface 121
Phase mutual friction, it is possible to reduce the abrasion of plate part 120, contact noise and sprocket 11 with flat
The friction of plate part 120.
Medial surface 121 has the central side 123 of flat shape, and it is comprising central crossbar portion 122
While in the height direction with retreat face 124 and be connected, the slab-thickness t3 on central side 123
More than at the slab-thickness t4 retreated on face 124.
Thus, owing to not only having slab-thickness t3 and the tool of the central part 133 of central side 123
The slab-thickness t4 having the backs 134 in retrogressing face 124 compares bigger, and planar shape,
And, retreating face 124 is the curve form of convex shape towards widthwise central face Pw, thus with retrogressing
Compare during the clinoplain shape that face 124 tilts in the height direction, there is the part in retrogressing face 124
Slab-thickness t4 becomes big, therefore, it is possible to improve the intensity of plate part 120, it is possible to increase flat part
Divide the durability of 120.
Due to retreat face 124 along with in the longitudinal direction from lengthwise centers face Pn near pin part 110
The curve form increased continuously in the width distance from widthwise central face Pw, therefore at sprocket
11 in the longitudinal direction, when space S 1 is engaged in the position of pin part 110 entrance the 1st, to retreat
Face 124 is the most more proximate to the position of pin part 110 and retreats the most significantly, so
Promote the phase avoiding the sprocket 11 after just initially entering the 1st engagement space S 1 with retrogressing face 124
Mutual friction, it is possible to reduce the abrasion of plate part 120, contact noise and sprocket 11 and flat board
The friction of part 120.
