Abstract
The utility model relates to a main transmission combine decelerator for a rough vertical roll. The main transmission combine decelerator is an integrated case body structure, whose input shaft is a spiral bevel gear shaft; two output gear shafts which are perpendicular to the input spiral bevel gear shaft are arranged inside the case body; one end of the input spiral bevel gear shaft is connected with a driven spiral bevel gear which is in connection with a helical gear shaft; the helical gear shaft is meshed with an intermediate gear which is connected with an output gear shaft I which is loaded with a driven gear I; the driven gear I is meshed with a second driven gear II which is connected with an output gear shaft II. The two output gear shafts are magnetically sealed with the end cap of the case body. The main transmission combine decelerator has the advantages that the decelerator realizes smooth transmission path, vertical transformation of the transmission path as well as the reallocation of the transferred torque, thus not only improving the transmission rigidity and the service life of the main transmission combine decelerator but also meeting the requirements of large torque transmission. Therefore, the main transmission combine decelerator of the utility model is particularly suitable for vertical rolls of roughing mill at the rough milling area of a medium-wide strip thermal mill production line.
Description
Technical field
The utility model belongs to the mechanical equipment of steel rolling technical field, particularly relates to a kind of main transmission associating speed reducer that is suitable for middle hot rolling line roughing district, broadband split rolling method with rough rolling vertical roller mill.
Background technique
At present, hot rolling line roughing blooming mill in broadband is generally the 70-800 flat roll mill in being usually used in, the main transmission speed reducer that its flat roll mill adopts, adopt split umbrella gear box structure, connect in the middle of the pressured plate of two umbrella gear box is fixing and by spline, so its whole transmission rigidity is poor, can't satisfy the high pulling torque delivery request, hot rolling line roughing district, broadband split rolling method rough rolling vertical roller mill in therefore not being suitable for.
Summary of the invention
The utility model provides a kind of whole housing structure for solving the technical problem that exists in the known technology, improved transmission rigidity and working life and be suitable in hot rolling line roughing district, broadband split rolling method with the main transmission associating speed reducer of rough rolling vertical roller mill.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the main transmission associating speed reducer of rough rolling vertical roller mill, it is characterized in that: main transmission associating speed reducer is a whole housing structure, the input shaft of described main transmission associating speed reducer is input spiral bevel gear wheel shaft, output gear shaft I vertical with importing the spiral bevel gear wheel shaft and output gear shaft П are installed in the casing, input spiral bevel gear wheel shaft one end is connected with passive spiral bevel gear, passive spiral bevel gear connects helical gear shaft by key, helical gear shaft engagement intermediate gear, intermediate gear connects the output gear shaft I that driven gear I is installed on it by key, driven gear I engagement driven gear П, driven gear П connects output gear shaft П, output gear shaft I and output gear shaft П and housing plate be sealed into the magnetic seal structure.
The utility model can also adopt following technological scheme:
Described magnetic seal structure is fixed on the output gear axle head by pressure ring, and magnetic seal is the magnetic seal A and the magnetic seal B of upper and lower settings.
Advantage and the good effect that the utlity model has are: because the utility model adopts whole housing structure, its output gear has adopted the spiral bevel gear wheel construction, to realize the reallocation of flat, upright conversion of drive path and transmitting torque, the transmission rigidity and the working life of main transmission associating speed reducer so both can have been improved, also can satisfy the high pulling torque delivery request simultaneously, so this main transmission associating speed reducer is specially adapted to middle hot rolling line roughing district, broadband split rolling method rough rolling vertical roller mill.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1.
Among the figure: 1, input spiral bevel gear wheel shaft; 2, passive spiral bevel gear; 3, helical gear shaft; 4, intermediate gear; 5, driven gear I; 6, output gear shaft I; 7, driven gear П; 8, output gear shaft П; 9, casing; 10, magnetic seal A, B; 11, pressure ring.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the main transmission associating speed reducer of rough rolling vertical roller mill, main transmission associating speed reducer is a whole housing structure, the input shaft of described main transmission associating speed reducer is input spiral bevel gear wheel shaft 1, output gear shaft I6 and the output gear shaft П 8 vertical with importing spiral bevel gear wheel shaft 1 are installed in the casing 9, input spiral bevel gear wheel shaft one end is connected with passive spiral bevel gear 2, passive spiral bevel gear connects helical gear shaft 3 by key, helical gear shaft engagement intermediate gear 4, intermediate gear connects the output gear shaft I6 that driven gear I5 is installed on it by key, driven gear I5 engagement driven gear П 7, driven gear П connects output gear shaft П 8, output gear shaft I and output gear shaft П and housing plate be sealed into the magnetic seal structure.This magnetic seal 10 is fixed on the end of output gear shaft I6 and output gear shaft П 8 by pressure ring 11, and magnetic seal is the magnetic seal A and the magnetic seal B of upper and lower settings.When output gear shaft I6 and П 8 drive magnetic seal A rotations, magnetic seal B is motionless, and magnetic seal A and magnetic seal B fit tightly by magnetic force, and two magnetic seals had not only relatively rotated but also do not produced the gap, thereby realize good sealing, prevent leakage of oil between output gear shaft and the casing.
The main driving motor of rough rolling vertical roller mill will rotatablely move and pass to the input spiral bevel gear wheel shaft 1 of main transmission associating speed reducer by coupling, input spiral bevel gear wheel shaft is passed to passive spiral bevel gear 2, thereby driving helical gear shaft 3 rotates, helical gear shaft drives output gear shaft I6 by intermediate gear 4 and rotates, the driven gear I5 that is fixed on the output gear shaft I6 also rotates simultaneously, and drive output gear shaft П 8 by driven gear П 7 and rotate, and then realize that drive path is flat, upright and transform and the reallocation of transmitting torque with output gear shaft I6 engagement.
