Abstract
The utility model belongs to the technical field of section steel and bar rolling mills, in particular relates to a speed change gear box for the section steel and bar rolling mill, and solves the problem that the conventional rolling mill can only achieve a speed ratio, which cannot satisfy the production requirement. The speed change gear box comprises a box body, and an input shaft and two synchronously rotating output shafts arranged in the box body; the speed change gear box is characterized in that two input gears are mounted on the input shaft; speed change gears meshed with the two input gears are mounted on an intermediate shaft arranged in parallel to the input shaft through bearings; an inner spline cover and an outer spline cover are mounted on the intermediate shaft between the two speed change gears; and output gears meshed with the input gears on the output shafts are further mounted on the intermediate shaft. The speed change gear box has the beneficial effects that two conventional speed ratio gear boxes are combined to one gear box, so that section steels and bars can be simultaneously segmented and rolled on a production line, and one rolling mill can achieve two speed ratios at the same time, that is, section steel rolling is completed at a high speed ratio and bar rolling is completed at a low speed ratio.
Description
Technical field
The utility model belongs to the technical field of shaped steel and rod product milling train, is specifically related to a kind of shaped steel, bar mill speed-change gear box.
Background technique
The gear-box that existing milling train is equipped with has only a kind of speed ratio usually, exports a kind of speed.And the finishing mill speed of rolls of producing bar at present requires comparatively fast, the finishing mill speed of rolls of producing section bar requires slower, so being difficult to satisfy, present rolling line finishing mill should roll bar rolled shaped material again simultaneously, because need the speed adjustment range bigger, a milling train can only be produced a kind of product usually.Can not satisfy the rolling of sectional iron of many kinds.
Summary of the invention
The utility model can only be finished a kind of speed ratio in order to solve existing milling train, can not satisfy the problem of production requirement, and a kind of shaped steel, bar mill speed-change gear box are provided.
The utility model adopts following technological scheme to realize:
Shaped steel, bar mill speed-change gear box, comprise casing, input shaft and two output shafts that rotate synchronously are set in the casing, it is characterized in that installing on the input shaft two input gears, have by Bearing Installation on the jack shaft that be arranged in parallel with input shaft and the speed change gears of two input gear engagement, the inside and outside cover of spline is installed on the jack shaft between two speed change gears, the input gear engagement on output gear and the output shaft also is installed on the jack shaft.
Can stir by shift fork and make that being enclosed within spline in the spline puts and can slide outward, thereby realize the engagement respectively of speed change gear.
The utlity model has following beneficial effect: existing two kinds of speed ratio gear casees are merged into a gear-box, solved the production line splitting rolling of rolled section steel and bar simultaneously, same rolling mill is finished two kinds of speed ratios simultaneously and is made large speed ratio completed mode steel rolling, and little speed ratio is finished rolling bar.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-casing, 2-input shaft, 3-speed change gear, 4-jack shaft, cover in the 5-spline overcoat, 6-spline, 7-output shaft.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further.
Shaped steel, bar mill speed-change gear box, comprise casing 1, input shaft 2 and two output shafts 7 that rotate synchronously are set in the casing 1, it is characterized in that installing on the input shaft 2 two input gears, be equipped with on the jack shaft 4 that be arranged in parallel with input shaft 2 and the speed change gears 3 of two input gear engagement, speed change gear by Bearing Installation on jack shaft, the inside and outside cover of spline is installed on the jack shaft 4 between two speed change gears 3, the input gear engagement on output gear and the output shaft 7 also is installed on the jack shaft 4.Shift fork is stirred to overlap in the spline and is made it put slip outside spline, and the one gear driven jack shaft of speed change gear is rotated, and exports a kind of speed ratio, another gear idle running of speed change gear; When needing the another kind of speed ratio of output, shift fork stirs that cover rotates another gear driven jack shaft of speed change gear in the spline.
Claims (1)
