Abstract
The utility model provides a bottom suspension runner for rolling mill, including the supporting body of roll, set up in the roller at supporting body of roll both ends, set up in roller both ends rather than the matched with bearing frame, be provided with the end cover that is connected with the bearing frame on the roller, the rectangle mounting groove has been seted up to the end cover, be provided with the elasticity water seal in the rectangle mounting groove, have in the elasticity water seal towards the tip extension of the supporting body of roll and the elastic stretch section of laminating mutually with the tip of the supporting body of roll, form the V -arrangement water sealed tank between elasticity water seal and the elastic stretch section, through setting up the elasticity water seal, through the V -arrangement water sealed tank that forms between its and the elastic stretch section, prevent that the extraneous water from getting into in the bearing frame, the bearing frame good seal, bearing lubrication obtains guaranteeing, the bearing life -span promotes greatly.
Description
Technical field
The utility model relates to a kind of lower support roll for milling train.
Background technology
As shown in Figure 1, lower support roll for milling train of the prior art, comprise the supporting body of roll, be arranged at the roll shaft at described supporting body of roll two ends, be arranged at the bearing block matched with it at described roll shaft two ends, described roll shaft is provided with the end cover be connected with described bearing block, tandem rolling back-up roll bearing adopts dry oil lubrication, seal owing to only adopting end cover, its poor sealing, the water inlet of lower support roll bearing block is serious, large to bearing infringement, bearing life is short, and milling train use cost is high.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned technology, thus provides a kind of lower support roll for milling train, good sealing effect.
The technical scheme that the utility model adopts is such: for the lower support roll of milling train, comprise the supporting body of roll, be arranged at the roll shaft at described supporting body of roll two ends, be arranged at the bearing block matched with it in described roll shaft two ends, described roll shaft is provided with the end cover be connected with described bearing block, described end cover offers rectangle mounting groove, elastic water sealed is provided with in described rectangle mounting groove, the end described elastic water sealed had towards the described supporting body of roll extends and the elastic extension section fitted with the end of the described supporting body of roll, V-arrangement water sealed tank is formed between described elastic water sealed and described elastic extension section.
Further improvement: the end face that described elastic water sealed and described end cover fit is provided with some waterproof grooves.
Further improvement: the thickness of described elastic extension section is thinning gradually to the direction of the described supporting body of roll by described elastic water sealed.
By adopting preceding solution, the beneficial effects of the utility model are: by arranging elastic water sealed, by the V-arrangement water sealed tank formed between itself and elastic extension section, prevent outside water from entering in bearing block, bearing block good seal, bearing lubrication is guaranteed, and bearing life promotes greatly.
Accompanying drawing explanation
Fig. 1 is prior art schematic diagram;
Fig. 2 is the utility model schematic diagram.
Wherein: 1, support the body of roll; 2, roll shaft; 3, bearing block; 4, end cover; 5, elastic water sealed; 6, elastic extension section; 7, V-arrangement water sealed tank; 8, waterproof groove.
Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, the utility model discloses a kind of lower support roll for milling train, comprise the supporting body of roll 1, be arranged at the roll shaft 2 at the described supporting body of roll 1 two ends, be arranged at the bearing block 3 matched with it in described roll shaft 2 two ends, described roll shaft 2 is provided with the end cover 4 be connected with described bearing block 3, described end cover 4 offers rectangle mounting groove, elastic water sealed 5 is provided with in described rectangle mounting groove, the end described elastic water sealed 5 had towards the described supporting body of roll 1 extends and the elastic extension section 6 fitted with the end of the described supporting body of roll 1, V-arrangement water sealed tank 7 is formed between described elastic water sealed 5 and described elastic extension section 6.
Principle: by arranging elastic water sealed 5, by the V-arrangement water sealed tank 7 formed between itself and elastic extension section 6, prevent outside water from entering in bearing block 3, bearing block 3 good seal, bearing lubrication is guaranteed, and bearing life promotes greatly.
Infiltrate to prevent the water between elastic water sealed 5 and end cover 4 in gap, the end face that described elastic water sealed 5 and described end cover 4 fit is provided with some waterproof grooves 8, and water outside being infiltrated by arranging waterproof groove 8 is stored in waterproof groove 8 and prevents it from continuing to infiltrate.
In order to improve the laminating effect between elastic extension section 6 and the supporting body of roll 1, the end of elastic extension section 6 is made to be close to the end face of the supporting body of roll 1, the thickness of described elastic extension section 6 is thinning gradually to the direction of the described supporting body of roll 1 by described elastic water sealed 5, thus the end elastic effect of elastic extension section 6 is good.
More than show and describe general principle of the present utility model and principal character and advantage thereof; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; above-described embodiment just illustrates principle of the present utility model with description in explanation; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
