Abstract
A one-drive-two combined rolling mill gear box comprises a box body (9), an input shaft (1) and an output shaft (10). The one-drive-two combined rolling mill gear box is characterized in that a helical gear is arranged at the end, located in the box body (9), of the input shaft (1), the helical gear is synchronously meshed with corresponding first large helical gears (2) at one ends of two first intermediate shafts (3), a first small helical gear is coaxially arranged on each first intermediate shaft (3), the first small helical gears are meshed with second large helical gears (4) on second intermediate shafts (5), second small helical gears of the second intermediate shafts (5) are meshed with third large helical gears (6) installed on third intermediate shafts (7), and third small helical gears (8) are coaxially installed on the third intermediate shafts (7) and meshed with a helical gear (11) installed on the output shaft (10). According to the one-drive-two combined rolling mill gear box, two horizontal type rolling mills are combined to one rolling mill for the first time which is of a one-drive-four power dividing structure, therefore, the requirement for rolling torque is met, the advantages of being stable in transmission and small in noise are achieved, the demands for steel materials are reduced, and the requirements for national energy saving and emission reduction are met.
Description
Technical field
The utility model relates to a kind of transmission device, especially a kind of one drag two milling train gear-box, and specifically a kind of bearing capacity is large, the one drag two associating milling train gear-box that transmission efficiency is high.
Background technique
At present, the common spur gear speed reducer that is usually used in of one drag two rolling mill reduction gears, this drive mechanism exist noise and vibration greatly, and bearing capacity is difficult to the series of problems such as raising.And along with the one drag two rolling mill reduction gears to improving constantly that speed and bearing capacity require, be badly in need of that a kind of speed of design is fast, reduction speed ratio is large, the high Novel speed reducer that can control effectively to improve working environment to noise simultaneously of bearing capacity for.
Summary of the invention
The purpose of this utility model is that the noise and vibration that exists for existing one drag two milling train gear-box is large, be difficult to satisfy the problem of the requirement of high-speed overload, design and a kind ofly can satisfy roll torque, can reduce again the one drag two associating milling train gear-box of noise and vibration.
The technical solution of the utility model is:
a kind of one drag two associating milling train gear-box, comprise casing 9, input shaft 1 and output shaft 10, the input end of input shaft 1 stretches out outside casing 9 and is connected with drive motor, one end of output shaft 10 stretches out casing 9 and is connected with milling train, it is characterized in that described input shaft 1 both sides are symmetrically installed with respectively the first jack shaft 3, the second jack shaft 5 and the 3rd jack shaft 7, described input shaft 1 is arranged on an end of casing 9 helical gear, the described helical gear first helical gear 2 corresponding with two the first jack shaft 3 one ends simultaneously is meshed, be coaxially arranged with the first bevel pinion on each first jack shaft 3, described the first bevel pinion is meshed with second largest helical gear 4 on being arranged on the second jack shaft 5, be coaxially arranged with the second bevel pinion on the second jack shaft 5, the second bevel pinion is meshed with the third-largest helical gear 6 on being arranged on the 3rd jack shaft 7, be coaxially installed with the 3rd bevel pinion 8 on the 3rd jack shaft 7, the 3rd bevel pinion 8 is meshed with helical gear 11 on being arranged on output shaft 10.
The distance ring 12 that makes helical gear 11 location is installed on described output shaft 10.
One end of described the 3rd jack shaft 7 stretches out outside casing 9.
The beneficial effects of the utility model:
The utility model is merged into two flat milling trains first a milling train one and drags four power dividing structure, has both satisfied the requirement of roll torque, has again stable drive, the advantage that noise is little, compact structure has reduced space hold and has reduced simultaneously materials'use, meets the requirement of energy-saving and emission-reduction.
The utility model is simple in structure, and is easily manufactured, and the life-span is long.
