Abstract
The utility model discloses a kind of dust-proof sealing structure of roll oil film bearing block, this structure comprises oil film bearing block rear end cover, seal ring and anchor ear, described seal ring set is located at described oil film bearing block rear end cover outer ring and the front-end face of seal ring extends to the step surface of roll pins having, and described anchor ear is located at described seal ring outer ring and is held tightly by seal ring in described oil film bearing block rear end cover.This structure enhances the dirt exclusion capabilities of oil film bearing block, avoids impurity to enter roll neck seal mechanism and causes water seal to be worn and torn, improve the working life of filmatic bearing, ensure that the normal production run of rolling line.
Description
Technical field
The utility model relates to a kind of dust-proof sealing structure of roll oil film bearing block.
Background technique
Rolling oil film bearing is a kind of sliding bearing, and its principle utilizes hydrodynamic theoretical, during roller rotational, forms a complete pressure film, metal is disengaged, the friction of formation neat liquid in roll and the working zone of bearing.Rolling oil film bearing has the advantages such as bearing capacity is large, long service life, velocity range are wide, physical dimension is little, friction factor is low, strong shock resistance, can meet the needs of various rolling mill practice, ensure that milling train low energy consumption runs.
Because the rolling oil film bearing working environment in mill milling is poor, especially hot rolling technology, the possibility entering rolling oil film bearing is carved with during the impurity such as the iron scale that a large amount of cooling waters, emulsified liquid and band steel come off, cause the water seal wearing and tearing of pressing close to body of roll end in roll seal arrangement in roll neck sealing mechanism excessive, lose sealing effect or sealing effect reduction, and then cause impurity to invade filmatic bearing, cause filmatic bearing leakage of oil, directly have influence on the working life of filmatic bearing, serious also can cause filmatic bearing scaling loss, affects the normal production run of rolling line.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of dust-proof sealing structure of roll oil film bearing block, this structure enhances the dirt exclusion capabilities of oil film bearing block, avoiding impurity to enter roll neck seal mechanism causes water seal to be worn and torn, improve the working life of filmatic bearing, ensure that the normal production run of rolling line.
For solving the problems of the technologies described above, the dust-proof sealing structure of the utility model roll oil film bearing block comprises oil film bearing block rear end cover, seal ring and anchor ear, described seal ring set is located at described oil film bearing block rear end cover outer ring and the front-end face of seal ring extends to the step surface of roll pins having, and described anchor ear is located at described seal ring outer ring and is held tightly by seal ring in described oil film bearing block rear end cover.
Further, described seal ring is provided with downward projection in the step surface position of roll pins having, and described projection is resisted against the step surface of roll pins having.
Further, described seal ring is provided with groove in described oil film bearing block rear end cover position, and described anchor ear is positioned at the groove of described seal ring.
Because the dust-proof sealing structure of the utility model roll oil film bearing block have employed technique scheme, namely this structure comprises oil film bearing block rear end cover, seal ring and anchor ear, described seal ring set is located at described oil film bearing block rear end cover outer ring and the front-end face of seal ring extends to the step surface of roll pins having, and described anchor ear is located at described seal ring outer ring and is held tightly by seal ring in described oil film bearing block rear end cover.This structure enhances the dirt exclusion capabilities of oil film bearing block, avoids impurity to enter roll neck seal mechanism and causes water seal to be worn and torn, improve the working life of filmatic bearing, ensure that the normal production run of rolling line.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the dust-proof sealing structure schematic diagram of the utility model roll oil film bearing block;
Fig. 2 is seal ring schematic diagram in this structure.
Embodiment
Embodiment as shown in Figure 1, the dust-proof sealing structure of the utility model roll oil film bearing block comprises oil film bearing block rear end cover 1, seal ring 2 and anchor ear 3, described seal ring 2 is sheathed on described oil film bearing block rear end cover 1 outer ring and the front-end face of seal ring 2 extends to the step surface 41 of roll 4 axle journal, and described anchor ear 3 is located at described seal ring 2 outer ring and holds seal ring 2 in described oil film bearing block rear end cover 1 tightly.
As shown in Figure 2, preferably, described seal ring 2 is provided with downward projection 21 in the step surface position of roll pins having, described protruding 21 step surfaces being resisted against roll pins having.This projection plays the effect of dust-proof lip.
Preferably, described seal ring 2 is provided with groove 22 in described oil film bearing block rear end cover position, and described anchor ear is positioned at the groove 22 of described seal ring 2.To guarantee that seal ring is reliably fixed on oil film bearing block rear end cover by anchor ear.
As shown in Figure 1, seal ring 2 is fixed on oil film bearing block rear end cover 1 by anchor ear 3 by this structure, seal ring 2 extends to the step surface 41 of roll 4 axle journal, make the gap between seal ring 2 masked film bearing support rear end cover 1 and roll 4 body of roll, and seal ring 2 is just in time positioned at the top of filmatic bearing water seal 5, thus cause water seal 5 to be worn and torn after avoiding impurity to enter this gap, improve the working life of filmatic bearing, guarantee the normal production run of rolling line.In addition when equipment repair and maintenance operation, remove seal ring 2 surface impurity after dismounting anchor ear 3, check the projection 21 of seal ring 2 simultaneously, when this projection 21 is less than 3MM, seal ring 2 must be changed, to ensure dust-proof effect.
