Abstract
The utility model discloses a sector roller structure of a continuous casting machine for wide and heavy plates. The sector roller structure comprises a left roller assembly and a right roller assembly which adopt the same assembly mode. In the left roller assembly, the left side and the right side of a mandrel (3) are respectively connected with a first bearing block (2) and a second bearing block (6) by the aid of a first spherical aligning cylinder roller bearing (1) and a second spherical aligning cylinder roller bearing (7), a circular ring roller bearing (5) is arranged in the middle of the mandrel (3), and two sectional rollers (4) are arranged on both sides of the circular ring roller bearing (5). The sector roller structure has the advantages of convenience in repair and maintenance and fine stressed state, and is capable of prolonging the service lives of the rollers and reducing the maintenance amount and time of the rollers.
Description
Technical field
The utility model relates to a kind of conticaster, especially a kind of wide thickness plate continuous casting machine fan-shaped section roller structure.
Background technology
At present, the requirements at the higher level that propose along with the continuous development of continuous casting technology and market, increasing iron and steel producer also progressively turns to eye wide thickness plate continuous casting machine and even special heavy plate conticaster field, this will inevitably all propose higher requirement to intensity, rigidity and the structure etc. as the fan-shaped section of conticaster core key equipment, and directly contact and transmit the roller assembling that strand is depressed power in establishing as fan-shaped section with strand, very under the bad working environments condition, inevitable requirement has a kind of more superior structural form in high temperature, heavy duty, deep-etching etc.
Existing fan-shaped section roller structure requires generally to be required to be four metamerism roller forms (as Fig. 1) if need to adapt to wide thickness plate continuous casting, it comprises long mandrel 3, described mandrel 3 two ends are provided with spherical aligning cylindrical roller bearing 1, the centre is provided with annulus roller bearing 5, going here and there between per two bearings on the mandrel 3 has a merogenesis roller, is provided with four metamerism rollers altogether on the whole axle core 3.This structure roller in the course of work along with factor affecting such as heavy duty applies, temperature distortions, roller, mandrel all have certain bending distortion, and because the characteristic of the long mandrel of this structure, its distortion can make four metamerism rollers and mandrel dismounting very difficult, and is inconvenient unusually during repair and maintenance.In addition, according to the mechanical characteristic of roller, the stressed maximum in roller center position, and this structure mandrel center only is provided with an annulus roller bearing, easily cause adverse consequences such as bearing load is overweight, reduce service life herein, this roller structure form is comparatively unreasonable.
The utility model content
The technical problems to be solved in the utility model provides the wide thickness plate continuous casting machine fan-shaped section roller structure that a kind of repair and maintenance is convenient, force-bearing situation is good.
For solving the problems of the technologies described above, the utility model institute by the following technical solutions.
A kind of wide thickness plate continuous casting machine fan-shaped section roller structure, it is characterized in that: comprise left side roller assembling and the assembling of right side roller of adopting identical assembling mode, in the roller assembling of described left side, the left and right sides of mandrel is connected with clutch shaft bearing seat, second bearing block by the first spherical aligning cylindrical roller bearing, the second spherical aligning roller bearing respectively, the mandrel middle part is provided with the annulus roller bearing, and described annulus roller bearing both sides are provided with the roller of two merogenesis roll-types.
Assembling of wherein said left side roller and right side roller assemble and adopt back-to-back that mode is connected.
Assembling relatively independent employing at and arranged on left and right sides roller of the present utility model leans against the dress mode and connects, every side roller all has the shorter mandrel of a roller, whole roller centre position has two second spherical aligning roller bearings, makes the stressed more reasonable of bearing, and roller structure is more good.Simultaneously, the roller distortion is effectively controlled in process of production, and the dismounting of repair and maintenance pair of rollers is comparatively convenient.
The utlity model has the advantage that repair and maintenance is convenient, force-bearing situation is good, it can improve the service life of roller, reduces the maintenance and the maintenance time of roller.
Description of drawings
Fig. 1 is original wide thickness plate continuous casting machine fan-shaped section roller structure schematic diagram;
Fig. 2 is the utility model structural representation;
Fig. 3 is the enlarged drawing of A among Fig. 2;
Fig. 4 is a stereogram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
It is extremely shown in Figure 4 as Fig. 2,
A kind of wide thickness plate continuous casting machine fan-shaped section roller structure comprises that the left side roller assembling and the right side roller that adopt mode back-to-back to connect assemble.Wherein in the assembling of left side roller, the left and right sides of mandrel 3 is connected with clutch shaft bearing seat 2, second bearing block 6 by the first spherical aligning cylindrical roller bearing 1, the second spherical aligning roller bearing 7 respectively, mandrel 3 middle parts are provided with annulus roller bearing 5, and annulus roller bearing 5 both sides are provided with the roller 4 of two merogenesis roll-types.Roller assembling in right side is except that the length of mandrel and roller is different, and remaining parts is assembled identical with the left side roller.
In the utility model, the left and right sides is independently two metamerism roller structures, adopts back-to-back that mode is connected on the sector-segment frames, has the advantage that repair and maintenance is convenient, force-bearing situation is good.
Claims (2)
1. wide thickness plate continuous casting machine fan-shaped section roller structure, it is characterized in that: described structure comprises left side roller assembling and the assembling of right side roller of adopting identical assembling mode, in the roller assembling of described left side, the left and right sides of mandrel (3) is connected with clutch shaft bearing seat (2), second bearing block (6) by the first spherical aligning cylindrical roller bearing (1), the second spherical aligning roller bearing (7) respectively, mandrel (3) middle part is provided with annulus roller bearing (5), and described annulus roller bearing (5) both sides are provided with the roller (4) of two merogenesis roll-types.
