Description
Technical field
The utility model relates to a kind of seal arrangement, especially a kind of filmatic bearing of press seal arrangement.
Background technique
Filmatic bearing claims fluid friction bearing again, and it is the sliding bearing of desirable liquid friction device, is often used in the milling train.Milling train utilizes the complete pressure oil film of formation in the wedge gap of liquid lubrication between tapered sleeve and lining in the course of the work, produces wedge effect, and tapered sleeve and lining that oil film will turn round at a high speed fully relatively separate, and direct Metal Contact does not take place.Filmatic bearing has possessed very strong bearing capacity in rotary course.The working environment very severe of filmatic bearing of press, except standing washing away of a large amount of cooling waters, the magazines such as a large amount of iron scales that also will be subjected to producing in the operation of rolling are invaded the danger of filmatic bearing.Seal arrangement is the important component part of filmatic bearing, is related to the normal operation of filmatic bearing.Existing seal arrangement sealing effect is poor, and sealing life is low, has influenced whole filmatic bearing and has run well, and has increased the user cost of milling train.
The model utility content
The utility model purpose is that the film bearing seal device of growing a kind of good sealing effect, sealing life is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of film bearing seal device, comprise tapered sleeve, roll, lining, bearing support and sealing cover, described tapered sleeve is enclosed within on the roll, and described lining is enclosed within outside the tapered sleeve, and described bearing support is installed in outside the lining, also has sealing cover on the described roll, described sealing cover links to each other with bearing support, and the opposing side of described sealing cover and bearing support is provided with oil trap, is with seal ring on the described roll; Described seal ring is provided with throws oily lip and sealing lip; The oily lip of described throwing stretches to the space that bearing support and sealing cover surround; Described sealing lip is L-shaped; " I " portion of described " L " shape sealing lip contacts with sealing cover; The below of described sealing cover is provided with center flange; Described " L " shape sealing lip is provided with two, lays respectively at the both sides of center flange; Be with the sealing outer shroud on the described roll; Described sealing outer shroud links to each other with sealing cover; Described seal ring is provided with aluminum ring device with the outer interannular of sealing; Be with water ring on the described roll; Described water ring contacts with the sealing outer shroud.
Preferably, described seal ring is provided with sealing hoop; Described sealing hoop is positioned between two " L " shape sealing lip.
Preferably, the face that contacts with roll of described seal ring is provided with the negative pressure cavity.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
A kind of film bearing seal device of the utility model scheme, good seal performance, sealing is long-lived long, has reduced the replacing frequency, has saved a large amount of funds, and the while also provides guarantee for the normal operation of whole filmatic bearing.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of film bearing seal device of the present utility model;
Wherein: 1, tapered sleeve; 2, roll; 3, lining; 4, bearing support; 5, sealing cover; 6, oil trap; 7, seal ring; 8, throw oily lip; 9, sealing lip; 10, center flange; 11, sealing hoop; 12, sealing outer shroud; 13, aluminum ring device; 14, water ring; 15, negative pressure cavity.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of film bearing seal device as shown in Figure 1, comprise tapered sleeve 1, roll 2, lining 3, bearing support 4 and sealing cover 5, described tapered sleeve 1 is enclosed within on the roll 2, described lining 3 is enclosed within outside the tapered sleeve 1, described bearing support 4 is installed in outside the lining 3, also has sealing cover 5 on the described roll 2, and described sealing cover 5 links to each other with bearing support 4, described sealing cover 5 is provided with oil trap 6 with the opposing side of bearing support 4, is with seal ring 7 on the described roll 2; The face that described seal ring 7 contacts with roll 2 is provided with negative pressure cavity 15; Described seal ring 7 is provided with throws oily lip 8 and sealing lip 9; The oily lip 8 of described throwing stretches to the space that bearing support 4 and sealing cover 5 surround; Described sealing lip 9 is L-shaped; " I " portion of described " L " shape sealing lip 9 contacts with sealing cover 5; The below of described sealing cover 5 is provided with center flange 10; Described sealing lip 9 is provided with two, lays respectively at the both sides of center flange 10; Described seal ring 7 is provided with sealing hoop 11; Described sealing hoop 11 is between two sealing lips 9; Be with sealing outer shroud 12 on the described roll 2; Described sealing outer shroud 12 links to each other with sealing cover 5; Described seal ring 7 and 12 of outer shrouds of sealing are provided with aluminum ring device 13; Be with water ring 14 on the described roll 2; Described water ring 14 contacts with sealing outer shroud 12.
