Abstract
The utility model relates to a rough-rolling vertical-roll gear box for a steel rolling mill. The rough-rolling vertical-roll gear box comprises a box body, an input gear shaft, a first-grade reduction gear shaft, a second-grade reduction gear shaft and two output shafts which are all arranged in parallel in the box body, wherein reduction gearwheels are respectively arranged on the first-grade reduction gear shaft and the second-grade reduction gear shaft through keys; and the input gear shaft and one ends of the two output shafts extend out of the box body. The rough-rolling vertical-roll gear box is characterized in that a couple of gear pairs are arranged on the two output shafts through keys, the speed ratio of the gear pairs is 1; and the input gear shaft is engaged with the reduction gearwheel in the first-grade reduction gear shaft, the first-grade reduction gear shaft is engaged with the reduction gearwheel in the second-grade reduction gear shaft, and the second-grade reduction gear shaft is engaged with an output gear on the adjacent output shaft.
Description
Technical field
The utility model relates to a kind of belt steel rolling gear-box, especially a kind of roughing edger roll gear-box that is used for strip mill.
Background technology
Roughing edger roll gear-box is the visual plant in the strip mill, and in two output shafts of existing roughing edger roll gear-box, an output shaft is provided with coaxial output gear and idle pulley; Another output shaft is provided with output gear, and behind output gear on output shaft of reduction gearing axle driving, the idle pulley by coaxial setting drives the output gear on another output shaft again; This type of drive; Complex structure not only, the volume and weight of gear-box is all bigger, and installation and maintenance are inconvenient.
The utility model content
The purpose of the utility model is; Volume and weight to the complex structure that exists in the roughing edger roll gear-box type of drive in the existing strip mill, gear-box is all bigger; A series of problems such as installation and maintenance inconvenience provide a kind of new roughing edger roll gear-box that is used for strip mill.
The purpose of the utility model is achieved in that a kind of roughing edger roll gear-box that is used for strip mill; Comprise casing, input gear shaft, first order reduction gearing axle, second level reduction gearing axle, and two output shafts; They are all through the parallel casing that is installed on of bearing; Through key a deceleration gear wheel is installed respectively on first order reduction gearing axle and the second level reduction gearing axle, an end of input gear shaft and two output shafts stretches out casing, it is characterized in that; Pass through the output gear that key is installed a pair of gear pair on two output shafts, the speed ratio between them is 1; Deceleration gear wheel engagement in input gear shaft and the first order reduction gearing axle, the deceleration gear wheel engagement in first order reduction gearing axle and the second level reduction gearing axle, the output gear on second level reduction gearing axle and the output shaft that closes on meshes.
In the utility model, said input gear shaft, first order reduction gearing axle and second level reduction gearing axle middle gear are the monocline tooth, and said deceleration gear wheel and output gear are the monocline tooth.
In the utility model, the end that input gear shaft and two output shafts stretch out casing is provided with oil sealing and passes through lid.
The advantage of the utility model is: owing to pass through the output gear that key is installed a pair of gear pair respectively on two output shafts; Speed ratio between them is 1; Cancelled the idle pulley that exists between two output shafts; Compact conformation not only, the volume and weight of gear-box is all smaller, and installation and maintenance are convenient.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, input gear shaft, 2, the deceleration gear wheel, 3, first order reduction gearing axle, 4, the deceleration gear wheel, 5, second level reduction gearing axle, 6, output gear, 7, output shaft, 8, output gear, 9, output shaft.
The specific embodiment
Accompanying drawing discloses the concrete structure of the utility model embodiment without limitation, below in conjunction with accompanying drawing the utility model is done further to describe.
Visible by Fig. 1; The utility model comprises casing, input gear shaft 1, first order reduction gearing axle 3, second level reduction gearing axle 5, and output shaft 7 and output shaft 9; They are all through the parallel casing that is installed on of bearing; Through key a deceleration gear wheel 2 is installed on the first order reduction gearing axle 3, through key a deceleration gear wheel 4 is installed on the second level reduction gearing axle 5, an end of input gear shaft 1, output shaft 7 and output shaft 9 stretches out casing; On output shaft 7 and output shaft 9, through key a pair of gear pair is installed, the speed ratio between them is 1; Deceleration gear wheel 2 engagements in input gear shaft 1 and the first order reduction gearing axle 3; Deceleration gear wheel 4 engagements in first order reduction gearing axle 3 and the second level reduction gearing axle 5; Output gear 8 engagements in output gear 6 engagements on second level reduction gearing axle 5 and the output shaft 7 that closes on, output gear 6 and output shaft 9.
In the present embodiment, said input gear shaft 1, first order reduction gearing axle 3 and second level reduction gearing axle 5 middle gears are the monocline tooth, and said deceleration gear wheel 2, deceleration gear wheel 4, output gear 6 and output gear 8 are the monocline tooth.
During practical implementation, the end that input gear shaft 1, output shaft 7 and output shaft 9 stretch out casing is provided with oil sealing and passes through lid.
