Embodiment 1

[0046] Such as Figure 4 , 5 , 6, and 7, a three-roll rolling mill with oil-water separation includes a rolling mill box 2, and the long axis 1 and the two short axes 3 driven by the long axis 1 through the bevel gears 4 at the left and right ends of the box are horizontally arranged in the box. The input end of the long shaft 1 is provided with cylindrical roller bearings, the long shaft 1 and the short shaft 3 are installed in the rolling mill box 2 through the tapered roller bearings 5 ​​and the bearing sleeves 9 at both ends respectively, and a roll 12 is respectively arranged in the middle of the three shafts. , the three rolls 12 are Y-shaped and form a Y-shaped emulsion chamber with the rolling mill box 2. Skeleton rubber oil seal 210 is installed between them, which also includes a sealing sleeve 6, the end face of the bevel gear 4 is pressed against the outer end face of the inner ring of the tapered roller bearing 5, and one end of the sealing sleeve 6 is connected ...

Embodiment 2

[0054] In this embodiment, the long axis is set at the bottom, and the short axis is set at the top. In fact, it is an improved three-roll rolling mill with lower transmission, such as Figure 8 , 9 shown. The components corresponding to each mark are the same as those in Embodiment 1, and details can be referred to in Embodiment 1 Figure 4 , 5 , 6, 7. The difference from Embodiment 1 is that the long axis 1 is on the bottom, and the two short shafts 3 are on the top, and the top of the rolling mill box 2 is provided with lubricating oil inlet holes to guide the lubricating oil in the oil chamber C to the two sides respectively. The bevel gear bearing 5 on the short shaft 3 is lubricated. The lower part of the rolling mill box 2 forms the left oil chamber A and the right oil chamber B for oil return. The sides of the rolling mill box 2 correspond to the two short shafts 3. The emulsion chambers 21 around the rolls 12 are respectively opened to lead the emulsion into the r...

Abstract

The invention discloses a three-high rolling mill with an oil-water separation function. A traditional small house is omitted, and the hole shape is adjusted through the eccentric adjusting principle.Linkage between upper worms and lower worms is achieved through synchronous gears, the hole shape can be adjusted only by adjusting one of the worms, the hole shapes of rollers can be adjusted on line, and the production efficiency is improved greatly. Long sealing sleeves are used for replacing original outer space rings and original inner space rings, and the outer circular faces of one ends ofthe sealing sleeves replace the rollers to make contact with third skeleton-type rubber seals; when the three-high rolling mill works, no relative movement exists between the sealing sleeves and therollers, relative rotation occurs between the third skeleton-type rubber seals and the outer circular faces of the sealing sleeves, thus abrasion of the rollers is avoided, and sealing performance isensured; and the isolating effect between lubricating oil and emulsion is further improved through first skeleton-type rubber oil seals mounted between bearing seat sleeves and the sealing sleeves.

Description

technical field [0001] The invention relates to a rolling mill, in particular to a three-roll rolling mill for oil-water separation, which belongs to the electrical and metallurgical machinery industry. Background technique [0002] For decades, in the electrical and metallurgical machinery industry, the rolling mills of the continuous casting and rolling production lines have been using a mixture of three-roll mills and two-roll mills. Among them, the three-roll mill is divided into an upper transmission three-roll mill and a lower transmission three-roll mill, of which figure 1 , 2 It is a three-roll rolling mill with upper transmission, image 3 It is a three-roll rolling mill with lower transmission. [0003] Now take the above transmission three-roll rolling mill as an example to illustrate the lubricating and cooling conditions of lubricating oil and emulsion in the prior art. Such as figure 1 , 2 As shown, serial number 1 is a small archway, one on each side; se...
