Into.
Then, the composition of seal member 19 is described in detail.
As shown in FIG. 2 and 3, seal member 19 possess with rigid circular inner circumferential side sealing ring 30 and
With rigid circular outer circumferential side sealing ring 31.Inner circumferential side sealing ring 30 is entrenched in the outer peripheral face 17a of bushing 17.Outer circumferential side
Sealing ring 31 is entrenched in the outer peripheral face of inner circumferential side sealing ring 30.In the present embodiment, inner circumferential side sealing ring 30 and outer circumferential side are close
Seal ring 31 is made up of steel respectively.
On the inner peripheral surface of inner circumferential side sealing ring 30 on the corner of inner link plate 12, by carry out chamfering and formed with
Inclined-plane 32.Also, by the inclined-plane 32 of inner circumferential side sealing ring 30, the lateral surface 12a of inner link plate 12, bushing 17 outer peripheral face
In the region that 17a is surrounded, to be compressed by inclined-plane 32, lateral surface 12a and outer peripheral face 17a, the state of elastic deformation is configured with
The 1st circular elastic ring 33.
That is, the 1st elastic ring 33 is arranged on the inclined-plane 32 of inner circumferential side sealing ring 30 and interior chain with the state compressed
Between the lateral surface 12a of section plate 12 and between inclined-plane 32 and the outer peripheral face 17a of bushing 17.In this case, if including
When the opposed face of the lateral surface 12a with inner link plate 12 on the week side of boss sealing ring 30 is as 1 opposed faces 34, at the 1st pair
Put between face 34 and the lateral surface 12a of inner link plate 12 formed with small gap.
On inner circumferential side sealing ring 30 with link plate 14 slip sliding side be provided with annular shape slide connecting part 35 and
Circular lubricant storing section 36, slide connecting part 35 slip the medial surface 14a in link plate 14, and lubricant storing section 36 is with sliding
Socket part 35 is adjacent.The lubricant being fed into slide connecting part 35 is held in lubricant storing section 36.The sealing ring 30 in inner circumferential side
On Outboard Sections radially, slide connecting part 35 by than lubricant storing section 36 more to link plate 14 it is prominent in a manner of set.
Lubricant storing section 36 forms the sliding side slipped on inner circumferential side sealing ring 30 with link plate.Lubricant stores
Portion 36 is formed in the whole circumference of inner circumferential side sealing ring 30 in the inner circumferential side than slide connecting part 35 more in the inner part, so as to lubricate
Step is formed between agent storing section 36 and slide connecting part 35.Therefore, in lubricant storing section 36 and the medial surface 14a of link plate 14
Between formed with small gap, pass through the lubrication between bushing 17 and link plate 14 to flow between bushing 17 and pin 20
Agent is held in the gap.
If when the face opposed with link plate 14 on outer circumferential side sealing ring 31 is as 2 opposed faces 40, the 2nd
1st groove 41 of the central portion radially of the outer circumferential side sealing ring 31 of opposed faces 40 formed with annular shape.Being fitted together in the 1st groove 41 has
The 2nd circular elastic ring 42.Because the depth-set of the 1st groove 41 is the thickness less than the 2nd elastic ring 42, so the 2nd elasticity
Ring 42 by the medial surface 14a of link plate 14 and the 1st groove 41 to be compressed and the state of elastic deformation is configured.
Therefore, the 2nd elastic ring 42 is close to the medial surface 14a of link plate 14 according to the elastic recovering force of itself.2nd
Elastic ring 42 is arranged between the medial surface 14a and outer circumferential side sealing ring 31 of link plate 14 with the state compressed.This
In the case of, formed with small seam between the 2nd opposed faces 40 of outer circumferential side sealing ring 31 and the medial surface 14a of link plate 14
Gap.
The face of close inner link plate 12 on outer circumferential side sealing ring 31 is formed as the lateral surface 12a with inner link plate 12
The sliding face 43 of sliding slide connecting part.The central portion radially of outer circumferential side sealing ring 31 on sliding face 43 is formed with annulus
2nd groove 44 of shape.2nd groove 44 is adjacent with the 1st groove 41 on width Y.The footpath of outer circumferential side sealing ring 31 in the 2nd groove 44
Upward width is set to that with the identical width of the 1st groove 41, its depth-set be the depth deeper than the 1st groove 41.
The 3rd elastic ring 45 of annular shape is embedded with the 2nd groove 44.3rd elastic ring 45 has and the identical of the 2nd elastic ring 42
Form.In this case, the depth-set of the 2nd groove 44 be slightly less than the 3rd elastic ring 45 thickness, the 3rd elastic ring 45 with
Compressed and the somewhat state configuration of elastic deformation by the lateral surface 12a of inner link plate 12 and the 2nd groove 44.Therefore, the 3rd elastic ring 45
The lateral surface 12a of inner link plate 12 is close to according to the elastic recovering force of itself.So, in the both sides of outer circumferential side sealing ring 31
The 1st groove 41 and the 2nd groove 44 of a pair of ring-types are respectively formed with, the 1st groove 41 and the 2nd groove 44, which have, is less than the He of the 2nd elastic ring 42
The depth of the thickness of 3rd elastic ring 45.Also, the 2nd elastic ring 42 and the 3rd elastic ring 45 are arranged respectively at a pair of the 1st grooves 41
With the 2nd groove 44.
In this case, because the depth-set of the 2nd groove 44 is the depth that is deeper than the 1st groove 41, so the 2nd elastic ring 42
Compression ratio be more than the 3rd elastic ring 45 compression ratio.Therefore, the elastic recovering force of the 2nd elastic ring 42 is more than the 3rd elastic ring 45
Elastic recovering force.Therefore, the 2nd elastic ring 42 is more than the 3rd elastic ring 45 to interior to the medial surface 14a of link plate 14 clinging force
The lateral surface 12a of link plate 12 clinging force.
That is, the 2nd elastic ring 42 of the both sides of outer circumferential side sealing ring 31 on width Y is configured in and
In 3rd elastic ring 45, it is configured in and is close to the 2nd elastic ring 42 of the identical side of the slide connecting part of inner circumferential side sealing ring 30 35
Power is more than the clinging force for the 3rd elastic ring 45 for being configured in the side opposite with slide connecting part 35.
1st elastic ring 33, the 2nd elastic ring 42 and the 3rd elastic ring 45 are made up of elastomers such as rubber respectively.
Then, the effect using the seal member 19 during chain 11 is illustrated.
When using chain 11, inner link plate 12 and link plate 14 are relatively rotated.Now, the 2nd elastic ring 42
It is more than the 3rd elastic ring 45 to the medial surface 14a of link plate 14 clinging force to be close to the lateral surface 12a of interior link plate 12
Power.Therefore, the elastic ring 45 of sliding face 43 and the 3rd of outer circumferential side sealing ring 31 is slided relative to the lateral surface 12a of inner link plate 12
Dynamic, the 2nd elastic ring 42 does not slide relative to the medial surface 14a of link plate 14, and maintains to be close to medial surface 14a state.
Inner circumferential side sealing ring 30 slides on slide connecting part 35 relative to the medial surface 14a of link plate 14.Therefore, inner circumferential side
Sealing ring 30, the 1st elastic ring 33 and bushing 17 integratedly rotate with inner link plate 12.Therefore, the 1st elastic ring 33 relative to
The outer peripheral face 17a's on the inclined-plane 32 of inner circumferential side sealing ring 30, the lateral surface 12a of inner link plate 12 and bushing 17 is close to state
It is maintained.
Composition more than is as can be seen that when the foreign matter such as the water for the outside for being present in chain 11 or dust enters chain 11
When internal, foreign matters pass through between the 2nd elastic ring 42 and the medial surface 14a of link plate 14.Therefore, foreign matter passes through outer circumferential side
Between the sliding face 43 of sealing ring 31 and the lateral surface 12a of inner link plate 12 and the 3rd elastic ring 45 and inner link plate 12 it is outer
Enter the inside of chain 11 between the 12a of side.
Now, foreign matter passes through between the 1st opposed faces 34 of inner circumferential side sealing ring 30 and the lateral surface 12a of inner link plate 12
Advance in gap.But the inclined-plane 32 of inner circumferential side sealing ring 30 and the lateral surface of inner link plate 12 are close to due to the 1st elastic ring 33
12a, so the entrance of foreign matter is blocked by the 1st elastic ring 33.
Therefore, the outer peripheral face and outer circumferential side sealing ring 31 that the foreign matter into the inside of chain 11 passes through inner circumferential side sealing ring 30
Inner peripheral surface between advance.Then, foreign matter passes through the slide connecting part 35 of inner circumferential side sealing ring 30 and the medial surface 14a of link plate 14
Between and the end face 17b of bushing 17 and the medial surface 14a of link plate 14 between enter the inner peripheral surface and pin 20 of bushing 17
Between outer peripheral face.
Therefore, foreign matter is being cut from the access path inside the outside entrance of chain 11 as shown in Fig. 3 dash-double-dot arrow
It is in crank-like when face is seen.That is, foreign matter becomes so-called labyrinth knot from the access path inside the outside entrance of chain 11
Structure.Therefore, with than before, foreign matter advances in the inside of seal member 19 becomes difficult.That is, with than before, by
Improved in the sealing of seal member 19, thus is effectively suppressed by seal member 19 foreign matter entered outside chain 11 it is interior
Portion.
When the lubricant between the inner peripheral surface of bushing 17 and the outer peripheral face of pin 20 escapes to the outside of chain 11, lubricant
By flowing into lubricant storing section 36 between the end face 17b of bushing 17 and the medial surface 14a of link plate 14.The lubricant stores
In lubricant storing section 36, and be fed into inner circumferential side sealing ring 30 slide connecting part 35 and link plate 14 medial surface 14a it
Between.
It is fed between the slide connecting part 35 of inner circumferential side sealing ring 30 and the medial surface 14a of link plate 14 and to the position
The lubricant being lubricated, it is impossible to by between the 2nd elastic ring 42 and the medial surface 14a of link plate 14.Therefore, lubricant exists
After flowing through between the outer peripheral face of inner circumferential side sealing ring 30 and the inner peripheral surface of outer circumferential side sealing ring 31, pass through outer circumferential side sealing ring 31
Between sliding face 43 and the lateral surface 12a of inner link plate 12 and the lateral surface 12a of the 3rd elastic ring 45 and inner link plate 12 it
Between and escape to the outside of chain 11.
Therefore, lubricant from the inside of chain 11 escape to outside spill path as shown in Fig. 3 dash-double-dot arrow,
It is in crank-like when section is seen.That is, lubricant from the inside of chain 11 escape to outside spill path equivalent to court
To the path in the direction opposite with the foreign matter direction of advance on the access path of foreign matter, and become so-called labyrinth structure.Cause
This, and than before, lubricant advances in the inside of seal member 19 becomes difficult.That is, with than before, due to close
The sealing for sealing part 19 improves, and is escaped to outside from the inside of chain 11 so effectively suppressing lubricant by seal member 19
Portion.
So, due to by seal member 19 by foreign matter from the outside distance for entering internal access path of chain 11 with
Lubricant from the inside of chain 11 escape to outside spill path distance be set to it is larger, so can effectively suppress different
Entrance of the thing from the outside of chain 11 internally, and lubricant can be suppressed and escape to outside from the inside of chain 11.Therefore, chain
The durability of bar 11 is enhanced.
According to above-mentioned embodiment, following effect can be obtained.
(1) in chain 11, inner circumferential side sealing ring 30 is so that the 1st elastic ring 33 of compressive state is located at inner circumferential side sealing ring
State between 30 and inner link plate 12 is sliding with link plate 14 on slide connecting part 35.Outer circumferential side sealing ring 31 is so that compression shape
State of 2nd elastic ring 42 of state between outer circumferential side sealing ring 31 and link plate 14 is in the sliding face 43 as slide connecting part
Upper and inner link plate 12 is sliding.That is, in chain 11, the slide connecting part 35 and outer circumferential side sealing ring of inner circumferential side sealing ring 30
31 sliding face 43 is located at opposite side on width Y and inner circumferential side sealing ring 30 and outer circumferential side sealing ring 31 are in its radial direction
It is upper directly to contact.Therefore, foreign matter from chain 11 it is outside enter inside access path and lubricant from the inside of chain 11
Escape to outside spill path become by the slide connecting part 35 of the medial surface 14a of link plate 14 and inner circumferential side sealing ring 30 it
Between, between the sliding face 43 of the lateral surface 12a of inner link plate 12 and outer circumferential side sealing ring 31 and inner circumferential side sealing ring 30 and outer
The path of between the week side of boss sealing ring 31, bending crank-like (labyrinth structure).Therefore, because foreign matter and lubricant exist respectively
The advance spilt on path of the access path and lubricant of foreign matter in chain 11 becomes difficult, so sealing can be improved
Sealing of the part 19 to foreign matter and lubricant.As a result, the durability of chain 11 can be improved.
(2) in chain 11, configuration on outer circumferential side sealing ring 31 the 1st groove 41 the 2nd elastic ring 42 to link plate
14 medial surface 14a clinging force be more than outer circumferential side sealing ring 31 on configuration the 2nd groove 44 the 3rd elastic ring 45 to inner link
The lateral surface 12a of plate 12 clinging force.The 2nd bullet is crossed therefore, it is possible to effectively suppress to be present in the foreign matter of the outside of chain 11
Property ring 42 and enter the slide connecting part 35 of inner circumferential side sealing ring 30, and can effectively suppress the slide connecting part to inner circumferential side sealing ring 30
35 lubricants being lubricated are crossed the 2nd elastic ring 42 and spilt to the outside of chain 11.
(3) in chain 11, slide connecting part 35 and lubricant storing section 36, slide connecting part are provided with inner circumferential side sealing ring 30
35 slip in link plate 14, and lubricant storing section 36 is adjacent with slide connecting part 35 and can store the lubrication supplied to slide connecting part 35
Agent.Therefore, it is possible to which the lubricant for being held in lubricant storing section 36 is successfully supplied to slide connecting part 35.
(4) in chain 11, the slide connecting part 35 of inner circumferential side sealing ring 30 is configured in the radial direction of the inner circumferential side sealing ring 30
On Outboard Sections.Therefore, because can on the inner circumferential side of the slide connecting part 35 than inner circumferential side sealing ring 30 more in the inner part and
The whole circumference side of inner circumferential side sealing ring 30 sets up lubricant storing section 36, is stored so lubricant can significantly be set
Portion 36.
(5) in chain 11, because the 1st elastic ring 33 does not slide, so the life-span becomes compared with the 3rd elastic ring 45 of slip
It is long.Therefore, in the case where the 3rd elastic ring 45 can not play a role, the 1st elastic ring 33 can be made as the 3rd elastic ring 45
It is standby and play a role.
