Abstract
The utility model discloses an upper roll device moving labyrinth structure for a short stress rolling mill, which comprises a roll and a roll box and is characterized in that a first moving labyrinth, a double-row cylindrical roller bearing and a second moving labyrinth are arranged on the outer ring of the roll; the bearing outer ring is provided with a roller box; the left side of the roller box is connected with a first labyrinth end cover through threads; the right side of the roller box is connected with a second labyrinth end cover through threads; the second labyrinth end cover is connected with a separated static labyrinth through threads. The utility model adopts the separated static labyrinth seal seam allowance and the moving labyrinth seal seam allowance to form the radial seal in a staggered way, thereby effectively solving the technical problems that the axial seal is easy to feed dust and is difficult to disassemble and replace in the prior art, further realizing that the dust is difficult to feed by adopting the radial seal and the assembly and disassembly are more convenient by adopting the separated static labyrinth.
Description
Technical Field
The utility model relates to the technical field of bar steel rolling, in particular to an upper roller device moving labyrinth structure for a short stress rolling mill.
Background
The rolling mill is needed in the rolling process of steel, a roller in the rolling mill is used for contacting the steel, a roller sleeve is arranged on a roller shaft, and the rotating power of the roller sleeve is transmitted through the roller shaft.
The sealing structure of the upper roller device in the prior art adopts an axial sealing structure with a movable labyrinth and a static labyrinth matched.
Nevertheless this application utility model people in the in-process of realizing utility model technical scheme in this application embodiment, discover that above-mentioned technique has following technical problem at least:
1. by adopting an axial sealing structure, dust can easily enter the inner part, and the use of the upper roller device is influenced.
2. The static labyrinth is inconvenient to disassemble and replace, and the dynamic labyrinth needs to be replaced firstly and then the static labyrinth needs to be replaced.
SUMMERY OF THE UTILITY MODEL
The embodiment of the application moves labyrinth structure through providing an last roller device for short stress rolling mill, has solved among the prior art axial seal and has easily advanced the technical problem that the dust and difficult dismantlement were changed, through adopting radial seal to easily advance the dust, and it is more convenient through adopting the quiet labyrinth installation of disconnect-type to dismantle.
The embodiment of the application provides a short stress rolling mill is with last roller device moves labyrinth structure, including roll and roller box, its characterized in that, the roll outer lane be provided with first maze, the double-row cylindrical roller bearing of moving and the second moves the maze.
And the bearing outer ring is provided with a roller box.
The left side of the roller box is connected with a first labyrinth end cover through threads.
And the right side of the roller box is connected with a second labyrinth end cover through threads.
The second labyrinth end cover is connected with a separated static labyrinth through threads.
The first labyrinth end cover and the first moving labyrinth are matched to form axial sealing.
The separated static labyrinth and the second moving labyrinth are matched to form radial sealing.
A first oil seal is arranged between the first labyrinth end cover and the first moving labyrinth.
And a second oil seal is arranged between the second labyrinth end cover and the second moving labyrinth.
The inner ring of the separated static labyrinth is provided with a plurality of groups of separated static labyrinth sealing rabbets.
And a plurality of groups of dynamic labyrinth sealing rabbets are arranged on the outer ring of the second dynamic labyrinth.
The separated static labyrinth seal seam allowance and the movable labyrinth seal seam allowance are arranged in a staggered mode to form radial seal.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
because the separated static labyrinth seal seam allowance and the movable labyrinth seal seam allowance are arranged in a staggered mode to form radial seal, the technical problems that dust is easy to enter an axial seal and the axial seal is not easy to detach and replace in the prior art are effectively solved, and the fact that the dust is difficult to enter through the adoption of the radial seal is further achieved, and the separated static labyrinth seal is more convenient to install and detach.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present application;
fig. 2 is a partial enlarged view at I in fig. 1.
Detailed Description
The embodiment of the application moves labyrinth structure through providing an last roller device for short stress rolling mill, has solved among the prior art axial seal and has easily advanced the technical problem that the dust and difficult dismantlement were changed, through adopting radial seal to easily advance the dust, and it is more convenient through adopting the quiet labyrinth installation of disconnect-type to dismantle.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Example one
The utility model provides a short stress is last roller device for rolling mill moves labyrinth structure, includes roll 2 and roller box 1, its characterized in that, 2 outer lanes of roll be provided with first maze 3, double-row cylindrical roller bearing 10 and second and move maze 9.
The outer ring of the bearing 10 is provided with a roller box 1.
The left side of the roller box 1 is connected with a first labyrinth end cover 5 through threads.
And the right side of the roller box 1 is connected with a second labyrinth end cover 7 through threads.
The second labyrinth end cover 7 is connected with a separated static labyrinth 8 through threads.
The first labyrinth end cover 5 and the first moving labyrinth 3 are matched to form axial sealing.
