Abstract
The utility model discloses a kind of milling train to float working roll stationary positioned device, relate to working roll, comprise bearing pin and bearing block, described bearing block is half closed-in construction, bearing setting up and down in it, described bearing is arranged in bearing seat frame by bearing pin, and bearing and bearing pin are rotatably assorted, and described bearing outer ring is spherical structure.The utility model adopts spherical design, replaces traditional face of cylinder bearing outer ring, and the linear contact lay becoming bearing and working roll termination is point cantact, eliminates the Relative friction between working roll and bearing.Enforcement of the present utility model, eliminates the Relative friction between working roll and bearing, greatly reduces the loss of bearing, eliminates because bearing and the working roll termination working roll caused that rubs damages phenomenon.
Description
Technical field
The utility model belongs to rolling equipment technical field, and it is simple to be specifically related to a kind of structure, and safe and reliable milling train floats working roll stationary positioned device.
Background technology
Multi-roll mill is mainly used in the thinner strip product of rolling, thus the work roll diameter directly contacted with the strip during rolling is less, the form of working roll many employings dancer during design, by the gate place, front and back of milling train install two cover cylinder roller bearings and working roll termination in the mode of CONTACT WITH FRICTION as the axial direction positioning device of working roll.During rolling owing to differing by raw material plate shape, the factor such as intermediate calender rolls roller curve and supporting roller bearing rigging error affects, certain axial force is produced to working roll, make working roll can be nondirectional toward two ends axial float, friction damage working roll termination and the bearing contacted with it.
The termination friction caused for reducing working roll axial float damages and bearing damage, under the prerequisite not changing gate configuration before and after milling train, need to redesign a kind of novel working roll stationary positioned device, under the effect of bearing identical work roll axial force, the wearing and tearing of working roll termination and bearing can be reduced.For this reason, develop a kind of structure simple, the reliable milling train of working stability floats working roll stationary positioned device, is conducive to the wearing and tearing reducing working roll termination and bearing, is necessary.
Utility model content
The purpose of this utility model is to provide a kind of structure simple, and the milling train that effectively can reduce wearing and tearing floats working roll stationary positioned device.
The purpose of this utility model is achieved in that and relates to working roll, comprises bearing pin and bearing block, described bearing block is half closed-in construction, bearing setting up and down in it, and described bearing is arranged in bearing seat frame by bearing pin, bearing and bearing pin are rotatably assorted, and described bearing outer ring is spherical structure.
The utility model adopts spherical design, replaces traditional face of cylinder bearing outer ring, and the linear contact lay becoming bearing and working roll termination is point cantact, eliminates the Relative friction between working roll and bearing.Common cylinder roller bearing outer ring is the face of cylinder, bearing and working roll termination are linear contact lay, because the working roll linear velocity at linear contact lay place is inconsistent, and contact position bearing outer ring speed is identical, working roll and bearing generation Relative friction are moved, time serious, causes bearing to be heated stuck working roll termination friction damage.Enforcement of the present utility model, eliminates the Relative friction between working roll and bearing, greatly reduces the loss of bearing, eliminates because bearing and the working roll termination working roll caused that rubs damages phenomenon.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is prior art structural representation;
In figure: 1-bearing pin, 2-bearing block, 3-bearing, 4-back-up ring, 5-working roll.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, but must not be limited the utility model by any way, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model relates to working roll 5, comprise bearing pin 1 and bearing block 2, described bearing block 2 is in half closed-in construction, bearing 3 setting up and down in it, described bearing 3 is arranged in bearing block 2 frame by bearing pin 1, and bearing 3 and bearing pin 1 are rotatably assorted, and described bearing 3 outer ring is spherical structure.The setting of spherical structure, makes the face contact form of traditional work roller end and bearing touch change into point cantact form, significantly reduces the loss of bearing.
Between described bearing 3, back-up ring 4 is set.
Described bearing pin 1 lower end is towards bearing block 2 arranged outside lock hole.Bearing 3 moves in a circle around bearing pin 1, in order to avoid departing from or axial float appears in bearing pin 1, therefore is provided with lock hole, uses the parts such as latch through lock hole, forms spacing cooperation with bearing block 2.Ensure that bearing pin 1 there will not be the situation of play.
Described back-up ring 4 is elastic opening back-up ring.
Described back-up ring 4 is loose rib or separate thrust collar.
Operation principle of the present utility model and the course of work:
The utility model adopts spherical design, is arranged in bearing block 2 by two cover bearings 3 by bearing pin about 1, installs back-up ring 4 in the middle of two cover bearings 3.Overlapped by the utility model two on the fixed or movable device being installed on working roll 5 two ends respectively, working roll 5 is 3-5mm with the assemblage gap of bearings at both ends 3, and wherein head is used for opening to be convenient for changing working roll.During rolling, two working rolls 5 are under the effect of axial force, irregular play is made toward two ends in non-directional ground, and cause top working roll bottom to contact with upper bearing (metal), bottom working roll top contacts with lower bearing, working roll 5 rotating band dynamic bearing 3 rotates, and plays the effect of steady job roller axial location.
