Abstract
The utility model discloses a cantilever roller bed preventing a roller head from falling off, which includes a roller head and a roller shaft. The roller head is mounted at the end part of a first end of the roller shaft and is in key connection with the roller shaft. The cantilever roller bed is characterized in that a radial annular boss is arranged at the end head of the first end in the axial direction of the roller shaft and contacted with a first end of the roller head. A second end in the axial direction of the roller head is connected with the roller shaft through welding. In the utility model, the radial annular boss is arranged at the end head of the first end in the axial direction of the roller shaft, thereby preventing the roller head from sliding off towards the inside of a furnace. Furthermore, the inner end of the roller head is connected with the roller shaft through welding, thereby ensuring the safety and the reliability of the roller head during production and operation, and greatly prolonging the service life of a cantilever roller.
Description
Technical field
The utility model belongs to the metallurgical machinery transmission field, particularly a kind of hanging arm roll that does not fall the roller head.
Technical background
Hanging arm roll is the very common a kind of mechanical transmission of smelting and heating industry.The roller head is one of hanging arm roll most important component as heating steel billet input and output transit link.In the application, the roller head often because problems such as design, manufacturing or welding come off aborning, has not only influenced normal production operation, and has increased the weight of the maintenance cost of maintenance personal's labour intensity and equipment.
The utility model content
The technical problems to be solved in the utility model is the deficiency that drops easily at existing its roller head of hanging arm roll and a kind of hanging arm roll that does not fall the roller head is provided.
The technical problems to be solved in the utility model can be achieved through the following technical solutions:
A kind of hanging arm roll that does not fall the roller head, comprise roller head, roll shaft, described roller head is installed in the end of roll shaft first end and is connected with the roll shaft key, it is characterized in that, termination at the first axial end of described roll shaft is provided with the annular radial boss, first end in contact of this annular radial boss and described roller head.
Second end and described roll shaft that described roller head is axial are welded to connect.
Owing to adopted technical scheme as above, the utility model is provided with the annular radial boss by the termination at roll shaft first end, has stoped the landing in stove of roller head.The inner and the roll shaft of roller head are welded to connect, have guaranteed the security reliability of roller head in production run, the service life of having improved overhang roll greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the scheme of installation between the utility model roller head and the roll shaft.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth embodiment of the present utility model.
Referring to Fig. 1, the hanging arm roll that does not fall the roller head shown in the figure, comprise roller head 1, roll shaft 2, water cooling tube 3, reduction box 6, reducing motor 8, swivel joint 7, roll shaft 2 is installed on the board 9 by bearing block 4,5, reduction box 6 is installed on the board 9, reducing motor 8 is connected with the power shaft of reduction box 6, output drive roller shaft 2 rotations of reduction box 6.
Termination at the first axial end of roll shaft 2 is provided with annular radial boss 17, and first end in contact of this annular radial boss 17 and roller head 1 has stoped roller head 1 landing in stove.Roller head 1 axial second end and roll shaft 2 welds, and guaranteed the security reliability of roller head in production run, the service life of having improved overhang roll greatly.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not subjected to the restriction of above-mentioned example; that describes in above-mentioned example and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
