The utility model discloses setting up aligning thrust roller bearing at veneer reeling machine lower roll roll body axle, changing original veneer reeling machine lower roll axle head and the sliding friction between the stud wall inboard side plate into rolling friction, it is big to have offset when roll system cone structure product the axial force to eliminate stand wallboard side plate and two lower roll axle end wears in and, greatly reduced is rateed to equipment trouble, thoroughly eliminates the defect of this type of equipment, improvement operating efficiency and processingquality.
Description
[technical field]
This utility model relates to veneer reeling machine technical field, is specifically related to roll structure under a kind of veneer reeling machine with roller bearings.
[background technology]
Veneer reeling machine is the special equipment rolling hardware, is mainly used in rolling cylinder and vertebral body structure part product.At present, veneer reeling machine two lower roller shaft end face generally directly contacts with liner plate inside column wallboard, cause veneer reeling machine in use, two lower roll axial forces are the biggest, make liner plate inside two lower roller shaft end faces and column wallboard come in contact and rub, cause column side lining liner plate and two lower roller shaft end wears.Time serious, after interior side plate mill is saturating, also accelerated wear test inside column wallboard.Typically just lose equipment serviceability in two months cycles of use, cause outage rate height, product quality to ensure, repair difficulty with expense relatively greatly, have a strong impact on product output and equipment service efficiency.
[summary of the invention]
For the problems referred to above, the purpose of this utility model is to solve liner plate inside lower roller of plate reeling machine end face and column wallboard, because coming in contact the problem easily causing heavy wear with sliding friction, to propose roll structure under a kind of veneer reeling machine with roller bearings.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that and is achieved:
Roll structure under a kind of veneer reeling machine with roller bearings, including lower roll roll body and column wallboard, described lower roll roll body axle head is provided with multiple opening bearing box with hollow cavity, and described bearing box is fixing with described column wallboard to be connected, and is provided with roller bearing in described bearing box.
Preferably, R10 chamfering made by the root car of described lower roll roll body beaming roller.
Preferably, being additionally provided with axle sleeve between described lower roll roll body axle head and roller bearing, R12 chamfering made by endoporus one end car of described axle sleeve, and described lower roll roll body axle uses interference fit with inner hole of shaft sleeve.
Preferably, described roller bearing is regulation of mental activities thrust roller bearing.
It is further preferred that described roller bearing is 29330 regulation of mental activities thrust roller bearings.
Preferably, the side of described bearing box is additionally provided with tank filler sleeve.
It is further preferred that the number of described bearing box is 2.
Preferably, described bearing box is connected by multiple bolts and column wallboard are fixing.
It is further preferred that described bolt is six square bolts in M12.
It is further preferred that the number of described bolt is 6.
Relative to prior art, this utility model has the advantages that
At lower roller of plate reeling machine, regulation of mental activities thrust roller bearing is set, change the sliding friction between liner plate inside original lower roller of plate reeling machine end and column wallboard into rolling friction, counteract the axial force when rolling cone structure product big, thus eliminate column wallboard and interior side plate and two lower roller shaft end wears, equipment failure rate is substantially reduced, thoroughly eliminate the defect of this kind equipment, improve working performance and crudy.
[accompanying drawing explanation]
Fig. 1 is this utility model structural representation；
In figure, 1 lower roll roll body, 2 axle sleeves, 3 bearing boxs, 4 roller bearings, 5 bolts, 6 column wallboards.
[detailed description of the invention]
Below in conjunction with the accompanying drawings this utility model is described further.
See Fig. 1, roll structure under a kind of veneer reeling machine with roller bearings, including lower roll roll body 1 and column wallboard 6, described lower roll roll body 1 axle head is provided with multiple opening bearing box 3 with hollow cavity, described bearing box 3 is fixing with described column wallboard 6 to be connected, and is provided with roller bearing 4 in described bearing box 3.Select bearing box, mainly location and the connection of column wallboard to roller bearing 4 loose ring, simultaneously dust-proof to outside (after having rolled up hardware, roll bending joint needs to slice off, and prevents welding slag from falling in bearing, affects the service life of bearing).
Preferably, R10 chamfering made by the root car of described lower roll roll body 1 beaming roller, it is to avoid in use, because radial force is very big, easily produces stress and concentrates, thus cause the phenomenon of the fracture of root of beaming roller.
Preferably, being additionally provided with axle sleeve 2 between described lower roll roll body 1 axle head and roller bearing 4, R12 chamfering made by endoporus one end car of described axle sleeve 2, and described lower roll roll body 1 axle uses interference fit with axle sleeve 2 endoporus, when solution roller bearing 4 assembles, it is impossible to be adjacent to by real difficult point with lower roll roll body 1 axle head.
Preferably, described roller bearing 4 is regulation of mental activities thrust roller bearing.
It is further preferred that described roller bearing 4 is 29330 regulation of mental activities thrust roller bearings, this bearing is possible to prevent equipment when rolling hardware, and lower roll roll body 1 occurs trace to bend, and the axial force to beaming roller makes a concerted effort to also play decomposition simultaneously.
Preferably, the side of described bearing box 3 is additionally provided with tank filler sleeve, to facilitate, roller bearing 4 is added grease.
It is further preferred that the number of described bearing box 3 is 2.
Preferably, described bearing box 3 is connected by multiple bolts 5 are fixing with column wallboard 6.
It is further preferred that described bolt 5 is six square bolts in M12, the number of described bolt 5 is 6.
The beneficial effects of the utility model are as follows: increase by two set regulation of mental activities thrust roller bearings at lower roller of plate reeling machine, change the sliding friction between liner plate inside original lower roller of plate reeling machine end and column wallboard into rolling friction, counteract the axial force when rolling cone structure product big, thus eliminate column wallboard and interior side plate and two lower roller shaft end wears.Structure of the present utility model can be used for the veneer reeling machine that other kinds model is sliding friction structure, and equipment failure rate is substantially reduced, and thoroughly eliminates the defect of this kind equipment, improves working performance and crudy.
