Description
Technical field
The utility model belongs to charge roll mill technical field, particularly relates to a kind of table roller for hot rolling beam-and-rail.
Background technology
On the beam-and-rail production line of the various model of rolling, specification, all kinds of conveying, work roller etc. are practical requirement, and large, the online quantity of single weight is many, is the severely afflicated area of cost control always.The concrete structure of existing roller as shown in Figure 1, it is comprised roll shaft 1 and is sleeved on the roller shell 2 on roll shaft 1 by bearing 3, one end of roll shaft 1 is the transmission side 6 for being connected with reductor, the other end is for the fore side 5 equipped with bearing block, roller is in long-term work, owing to limiting by its operating mode, from the abrasion condition of the retired roller of most of rolling line, the working surface usable floor area of the roller shell of roller only has about 20% ~ 30%, and on roller shell adjacent wear surface 4 is relatively far apart, get rid of the cause specific of rail rolling technique, the working face utilization rate of roller also only has about 50%, waste huge, thus cause production cost to raise.
Summary of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of table roller for hot rolling beam-and-rail.
In order to realize foregoing invention object, the utility model adopts technical scheme as described below:
A kind of table roller for hot rolling beam-and-rail, it comprises roll shaft, bearing and roller shell, roller shell is sleeved on the axle body of roll shaft, the inwall at two ends, roller shell left and right is all fitted with bearing, two bearings is sleeved on roll shaft, and both ends, the left and right structure of roll shaft is identical, and roll shaft both ends are equipped with step-like shaft part A, the end face of shaft part A is connected with shaft part B, and the periphery of shaft part B offers keyway.
Owing to adopting technique scheme, the utility model has following superiority:
The roll shaft both ends of existing roller are all set to transmission side by the utility model, make the roller shell of roller after use a period of time produces comparatively heavy wear, exchange on the right side of roller integral left, just can again come into operation, and when again utilizing, the new wear surface that roller shell surface produces then just is positioned at the roller shell of non-experience wear on the surface, has increased substantially the whole service life of roller, has reduced production cost.

Fig. 2 is the schematic diagram after roll wear of the present utility model;
In figure: 1-roll shaft; 2-roller shell; 3-bearing; 4-wear surface; 5-fore side; 6-transmission side; 7-shaft part A; 8-shaft part B; 9-keyway.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 2, a kind of table roller for hot rolling beam-and-rail, it comprises roll shaft 1, bearing 3 and roller shell 2, roller shell 2 is sleeved on the axle body of roll shaft 1, and the inwall at roller shell about 2 two ends is all fitted with bearing 3, and two bearings 3 is sleeved on roll shaft 1, both ends, the left and right structure of roll shaft 1 is identical, roll shaft 1 both ends are equipped with step-like shaft part A7, and the end face of shaft part A7 is connected with shaft part B8, the periphery of shaft part B8 offers keyway 9.
Described shaft part A7, shaft part B8 and roll shaft 1 are integrated machine-shaping structure.
When mounted, be connected with reductor one end of roll shaft, the other end is connected with bearing block the utility model, bearing block also can arrange a bearing (ball) cover, bearing (ball) cover is provided with protective jacket, and the bearing face be attached in roller shell is pushed up in the end of protective jacket; Bearing (ball) cover can effectively prevent dust foreign material from entering in roller shell, and the shaft part A protected on roll shaft and shaft part B.
The roll shaft both ends of existing roller are all set to transmission side by the utility model, make the roller shell of roller after use a period of time produces comparatively heavy wear, exchange on the right side of roller integral left, just can again come into operation, and when again utilizing, the new wear surface 4 that roller shell surface produces just is positioned at the roller shell of non-experience wear on the surface, has increased substantially the whole service life of roller, has reduced production cost.
