Description
Technical field
The present invention relates to a kind of gear-box, especially a kind of heat radiation and transmission integrated milling train special gear box, specifically one one is entered six and is gone out integrated tube rolling special gear box.
Background technology
As everyone knows, milling train is important metallurgical equipment, and milling train gear-box is the key equipment ensureing that milling train normally works.At present, milling train both domestic and external is all structures of single chassis selective gear case heating/cooling device again, and this portfolio investment is large, and floor space is large, and manufacturing cost is high, and controls the drawbacks such as adjustment is complicated.Therefore the novel kind of drive is designed very necessary.
Summary of the invention
The object of the invention is for existing milling train gear-box is all adopt cabinet and cooling two covering devices to ensure that gear-box normally runs, thus cause that equipment volume is large, cost is high, the problem of adjustment inconvenience, designs and is a kind ofly merged with gear-box by cooling device thus eliminate one of cooling device to enter six and go out integrated tube rolling special gear box.
Technical scheme of the present invention is:
A kind of one enters six goes out integrated tube rolling special gear box, it comprises the casing be connected to form by lower box 1 and upper box 2, it is characterized in that, in the center of described casing, idle pulley 5 is installed, idle pulley 5 is meshed with an input gear and five output gears simultaneously, input gear is arranged on input tooth axle 4, one end of input tooth axle 4 is connected with prime mover, the other end stretches out casing and is connected with the 6th working roll as output shaft, five output gears are installed on corresponding output gear axle 7, the output gear axle 7 that five output gears are corresponding is connected with first to the 5th working roll respectively, described idle pulley 5 is arranged on water jacket 6, water jacket 6 is sleeved on mandrel 8, the two ends of water jacket are supported on the tank wall of casing, cooling-water duct 9 is formed between the internal face and the outer surface of mandrel 8 of water jacket 6, cooling water enters from the water inlet 10 of one end of cooling-water duct 9, flows out from the delivery port 11 of the other end.
Described mandrel 8 is hollow shaft.
Described water inlet 10 and delivery port 11 are inclined hole.
The position of described input tooth axle 4 is depended on can change the position of prime mover according to the change of prime mover position.
Beneficial effect of the present invention:
The present invention, by tube rolling gear-box and cooling device being combined, a set of tube rolling gear-box completes two kinds of functions.Gear-box is crossed cover by six roller gear casees and water-cooled and is formed.Wherein a driving wheel is power shaft and output shaft, and power shaft, by other five output shaft synchronous transmissions of gear driven broad in the middle, ensure that the synchronous uniformity exporting transmission.
The inside of gear housing of the present invention be designed to the stop collar of water jacket cooling, ensure that the stable of operation of rolling product size, and reduce the impact that high temperature brings to drive bearing, extend bearing service life.

Fig. 1 is that the utility model faces structural representation.
Fig. 2 is the utility model sectional median plane schematic diagram.
Fig. 3 is the utility model power shaft generalized section.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As Figure 1-3.
A kind of one enters six goes out integrated tube rolling special gear box, it comprises the casing 3 be connected to form by lower box 1 and upper box 2, in the center of described casing, idle pulley 5 is installed, idle pulley 5 is arranged on water jacket 6, water jacket 6 is sleeved on mandrel 8, the two ends of water jacket 6 and mandrel 8 are respectively provided with sealing spacer 12, mandrel 8 is preferably designed to hollow-core construction, as shown in Figure 2, the two ends of water jacket 6 are fixedly supported on the tank wall of casing, cooling-water duct 9 is formed between the internal face and the outer surface of mandrel 8 of water jacket 6, cooling water enters from the water inlet 10 of one end of cooling-water duct 9, flow out from the delivery port 11 of the other end, water inlet 10 connects workshop recirculated water in order to reduce the conduction of hot operation part to temperature, reduce temperature to the impact of bearing, water inlet 10 and delivery port 11 all can be designed to inclined hole.Idle pulley 5 is meshed with an input gear and five output gears simultaneously, totally six input and output gears are distributed on idle pulley 5 around, as shown in Figure 1, input gear 14 is arranged on input tooth axle 4, one end of input tooth axle 4 is connected with prime mover, the other end stretches out casing and is connected with the 6th working roll as output shaft, and five output gears are installed on corresponding output gear axle 7, and the output gear axle 7 of five output gear 13 correspondences is connected with first to the 5th working roll respectively; According to the difference of prime mover position, input tooth axle 4 can be arbitrary in Fig. 1, and the input tooth axle in the present embodiment is positioned at Fig. 1 lower right position, as shown in Figure 3.
In Fig. 1, position, bosom is the end view drawing of idler shaft (water jacket 6), the six roots of sensation axle of idler shaft surrounding can unified definition be output gear axle, but wherein have the while of piece and be connected with prime mover as power shaft, that is, namely the arbitrary axle except idler shaft in Fig. 1 can be used as power shaft.Idle pulley 5 of the present invention is arranged on water jacket 6 by bearing, due to stress balance, therefore the moment of flexure stress of water jacket 6 is less, remaining input and output gear is all connected with corresponding input and output tooth axle entirety or is connected by key pin, and the two ends of input and output shaft are bearing on two walls of casing by bearing.
Prime mover (as motor) drives the input gear 14 of input tooth axle 4 to rotate, thus drive idle pulley 5 to rotate, the output gear that idle pulley 5 drives all the other five to be meshed again rotates, output gear drives output gear axle 7 to rotate again, thus drive corresponding roll rotation, the other end of input tooth axle 4 is directly connected with the 6th roll, thus through the steady output speed of gear-box, six working rolls are driven to rotate, six working rolls all obtain rational distribute torque, achieve the peak use rate of material, and effectively reduce the temperature of bearing.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
