Take Fig. 2 as master and suitably with reference to figure 1, and hermetically-sealed construction 150 is configured between surrounding space A and bearing 145 in the axial direction, is configured in diametrically lining 132 and advances between roller 140.
The hermetically-sealed construction 150 configuring adjacently with bearing 145 in the axial direction has: near the outer seal 151 of surrounding space A; Inboard seal 152 near bearing 145; Have by inclosure and be formed on the grease seal portion 160 that the grease between outer seal 151 and inboard seal 152 accumulates the grease G1 in chamber 153; And outside grease seal portion 155.
Grease accumulates chamber 153 for surrounding in a circumferential direction the annulus of roll shaft 131.Grease seal portion 160 has and is configured in grease and accumulates grease G1 and the more than one felt sealing member F in chamber 153.The number of the felt sealing member F that grease seal portion 160 has in the present embodiment for a plurality of, that is, is 2 as regulation number.
Felt sealing member F is the filter material sealing member being formed by the felt as filter material, is circle shape part.
Grease G1 and felt sealing member F accumulate at grease that chamber 153 is interior forms respectively grease seal floor Sg and as the felt sealing layer Sf of filter material sealing layer, grease seal layer Sg is the sealing layer S configuring in the orientation of outer seal 151 and inboard seal 152 stackedly.
In the present embodiment, orientation is that axially orientation is grease seal layer Sg and felt sealing layer Sf stacked stacked direction between outer seal 151 and inboard seal 152.
Outer end sealing layer 161, inner sealing layer 162 and the second intermediate seal layer 164 are grease seal layer Sg.
Be configured in the first intermediate seal layer 163 between outer end sealing layer 161 and the second intermediate seal layer 164 and be configured in inner sealing layer 162 and the second intermediate seal layer 164 between the 3rd intermediate seal layer 165 are the felt sealing layer Sf as particular filter material seal layer.
Felt sealing member F has the circular plate of thickness T in the axial direction, and is entrenched in lining 132 and is advanced between roller 140 by interference fit.Therefore, the external diameter that the internal diameter on the interior perimembranous Fi of felt sealing member F accumulates the lining 132 on chamber 153 than grease is little, and the internal diameter that the external diameter on the peripheral part Fo of felt sealing member F accumulates the roller 140 of advancing on chamber 153 than grease is large.
Felt sealing member F is maintained on lining 132 with the state contacting with lining 132 on interior perimembranous Fi on the complete cycle of interior perimembranous Fi, and on the complete cycle of peripheral part Fo, with the state contacting with the roller 140 of advancing, is maintained at and advances on roller 140 on peripheral part Fo.
Felt sealing member F is formed by synthetic resin fiber, at this, by poly-ester fibres and polyurethane fiber, is formed, and preferably, its constituent has 60% polyester and 40% polyurethane.In felt sealing member F, contain and be soaked with lubricating oil.
Outside grease seal portion 155 is configured in more to lean on the position of surrounding space A and the diametrically opposed annular seal portion that is configured in radial outside in interval setting ring 133 than outer seal 151 in the axial direction.Outside grease seal portion 155 applies grease G2 and forms to cover all modes of outer seal 151 with respect to surrounding space A.The viscosity of grease G2 is less than the viscosity of the grease G1 of grease seal layer Sg.
Next, effect and the effect of the embodiment forming are in the above described manner described.
By such structure, foreign matter in being present in surrounding space A invades grease through outer seal 151 and accumulates chamber 153 when interior, invade foreign matter (, invade grease and accumulate the foreign matter in chamber 153) be trapped in the grease G1 of grease seal portion 160, therefore can suppress to invade foreign matter to the intrusion of bearing 145.
In grease seal portion 160, grease G1 and felt sealing member F within grease accumulates chamber 153, be respectively formed at as orientation axially on stacked grease seal floor Sg and the felt sealing layer Sf configuring.Grease seal layer Sg and felt sealing layer Sf are alternately laminated into five sealing layer S in the axial direction layer by layer.
By such structure, because grease seal portion 160 is grease seal layer Sg and the felt seal layer Sf stacked multi-layer sealed portion forming alternately, the solid intrusion foreign matter of therefore invading in foreign matter is caught by felt sealing member F, thus from as first of felt sealing layer Sf, the 3rd intermediate seal layer 163, 165 arrive as the second intermediate seal layer 164 of bearing side grease seal layer and the minimizing of the solid of inner sealing layer 162 intrusion foreign matter, and, as the liquid that has passed through the intrusion foreign matter of this felt sealing layer Sf, invade foreign body retention at this bearing side grease seal layer (, the second intermediate seal layer 164 and inner sealing layer 162) grease G1 in.Therefore, the intrusion foreign matter that arrives inboard seal 152 and bearing 145 reduces, and can realize thus raising and the long lifetime of the leak tightness of grease seal portion 160, when therefore can improve the leak tightness of hermetically-sealed construction 150, extends the life-span of hermetically-sealed construction 150.
In addition, be sealing into that grease accumulates that grease G1 in chamber 153 usings that grease seal CengSgWei unit is maintained between the first, the 3rd intermediate seal floor 163,165 as a pair of felt sealing layer Sf, outer seal 151 and as between the first intermediate seal floor 163 of felt sealing layer Sf and between inboard seal 152 and the 3rd intermediate seal floor 165 as felt sealing layer Sf.Therefore, suppressed by felt sealing member F by the outflow that the caused grease of fluidization that causes accumulates chamber 153 from grease of rising of the temperature of the rotation based on the roller 140 of advancing, therefore can improve grease G1 accumulates the retentivity in chamber 153 at grease.
All felt sealing layer Sf of grease seal portion 160 are configured between a pair of in the axial direction grease seal layer Sg as particular filter material seal layer respectively.
By such structure, even decline because of deteriorated its leak tightness that causes of foreign matter of invading as the outer end sealing layer 161 of leading portion grease seal layer or the grease G1 of the 3rd intermediate seal layer 165, having passed through solid in the intrusion foreign matter of this leading portion grease seal layer invades the first intermediate seal layer 163 or the 3rd intermediate seal layer 165 that foreign matter is used as particular filter material seal layer and catches, the liquid of invading in foreign matter is invaded foreign matter through after particular filter material seal layer, be trapped in the second intermediate seal layer 164 or inner sealing layer 162 as back segment grease seal layer, therefore can improve the leak tightness of grease seal portion 160, and can extend the life-span of grease seal portion 160.
Hermetically-sealed construction 150 has the outside grease seal portion 155 being formed by all grease G2 of relative surrounding space A covering outer seal 151, outside grease seal portion 155 suppresses foreign matter sealing member 151 intrusions laterally thus, therefore the leak tightness of grease seal portion 160 can be improved, and the life-span of grease seal portion 160 can be extended.
Felt sealing member F is fitted to lining 132 by interference fit and advances between roller 140, each felt sealing member F is maintained at grease with simple structure and accumulates in chamber 153 and do not move in the axial direction, therefore the stacked state of grease seal layer Sg and felt sealing layer Sf is kept reliably, thereby contributes to the raising of the leak tightness of grease seal portion 160.
In addition, by soaking by lubricating oil in felt sealing member F, reduce with the lubricating oil of the friction force of advancing on the felt sealing member F of roller 140 interlocks rotations and the slide connecting part of advance roller 140 and lining 132 because of impregnation in felt sealing member F, the rotational resistance of the roller 140 of advancing therefore being caused by the felt sealing member F of interference fit reduces.Therefore, the loss due to friction of advancing in roller 140 reduces, thereby can reduce the energy consumption of the chain drive that chain 100 is driven.
Further, because the lubricating oil of impregnation in felt sealing member F suppresses passing through of liquid foreign matter, the leak tightness of therefore invading foreign matter for liquid in felt sealing layer Sf improves, thereby can improve the leak tightness of grease seal portion 160.
In addition, because outer end sealing layer 161 and inner sealing layer 162 are grease seal layer Sg, therefore compare for the situation of felt sealing layer Sf with two sealing layers 161,162, by the fricative rotational resistance of advancing roller 140 between outer seal 151 and inboard seal 152 and felt sealing member F, reduced, the loss due to friction of therefore advancing in roller 140 reduces.
Because felt sealing member F is the felt sealing member F that the felt by consisting of polyester and polyurethane forms; therefore the felt consisting of polyester and polyurethane in intensity (; resistance to deformability), the catching property aspect of dimensional stability and solid foreign materials is excellent; therefore can, in the required foreign matter seizure property of guaranteeing based on felt sealing member F, reduce the thickness T of felt sealing member F.Therefore, can grease seal portion 160 miniaturization in the axial direction of felt sealing layer Sf will be there is, or, at the grease with the axial length of regulation, accumulate in chamber 153, by increasing the number of felt sealing layer Sf, the leak tightness of grease seal portion 160 can be improved, and the life-span of grease seal portion 160 can be extended.
Below, about a part of structure of the above embodiments having been carried out to the embodiment of change, to having carried out the structure of change, describe.
The roll structure body replacement roller 123 of advancing with the roller 140 of advancing can be set.Now, coupling pin 120 and sleeve 122 form roll shaft parts.
