The utility model discloses float the bearing frame and fix on the bracket of support bearing seat, make slightly beat of bearing frame to restrict the beat of whole homalocephalus cover, reduce freely beating of homalocephalus cover, prolonged homalocephalus cover life, bracket along the two -way removal of axial can realize the meshing and the separation of rolling -mill roll and homalocephalus axle sleeve, the quick replacement rolling mill simultaneously.
Description
Technical field
The utility model relates to milling train field, is specifically related to a kind of milling train flat head sleeve.
Background technology
Milling train is the equipment realizing metal rolled process.The Zhuan Bei ﹐ having made a general reference stocking production overall process includes Zhu and wants She Bei ﹑ Fu to help She Bei ﹑ handling equipment and auxiliary device etc., and working stand is made up of Zha Gun ﹑ Zha roll shaft Cheng ﹑ Tuo Jia ﹑ Gui Zuo ﹑ Roller. redress Zhuan Zhi ﹑ top-roll-balance arrangement and changing rig etc.Mill drive axle is the equipment connecting main transmission and roll, and wherein flat head sleeve is then that main shaft follows roll directly to contact, for the vitals of homalocephalus location and carry-over moment.The rolling operation of metallurgical industry rolling mill is by the flat head sleeve be connected with main shaft, flat head sleeve by the homalocephalus that is connected with roll by power transmission to roll, rotate to drive it.Under normal circumstances, homalocephalus is with flat head sleeve with the use of the transmission to complete power, and flat head sleeve plays the effect of transmitting rolling torsion.Existing flat head sleeve endoporus comprises a pair arc surface and pair of planar, and arc surface is relative between two, unilateral also relative between two, and plane is provided with liner plate, and liner plate plays the effect of transmitting torque.
But this flat head sleeve in use, has the following disadvantages: 1. inserted by homalocephalus after in flat head sleeve endoporus, two circular arcs in flat head sleeve endoporus directly contact with homalocephalus, make this arc surface serious wear, shorten the service life of flat head sleeve.2. repair difficulty after the wearing and tearing of flat head sleeve arc surface large, rehabilitation expense is high.3. there is gap between homalocephalus and flat head sleeve, steam can directly enter in this gap, heavy corrosion flat head sleeve endoporus.
Utility model content
The purpose of this utility model is to provide a kind of milling train flat head sleeve, improves the service life of flat head sleeve.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: provide a kind of milling train flat head sleeve, comprises homalocephalus axle sleeve and end-tooth ring flange, passes through Flat dey joint between homalocephalus axle sleeve and end-tooth ring flange; Be provided with the bearing block supporting flat head sleeve and move between homalocephalus axle sleeve and end-tooth ring flange, offer axis hole, be provided with neck bush in axis hole in homalocephalus axle sleeve, the end face of homalocephalus axle sleeve is provided with external bushing.
Optimize, homalocephalus axle sleeve is fixedly connected with external bushing by lining connecting bolt.
Optimize, end-tooth ring flange is provided with pressing plate and connecting bolt.
Optimize, end-tooth ring flange is connected with shaft coupling by bolt.
Optimize, bearing block floats and is fixed on the bracket of supporting bearing base; Bearing block is provided with bearing.
Optimize, bearing block lower end is provided with the chain stretching device hole be connected with spindle carrier.
Optimize, homalocephalus axle sleeve and end-tooth ring flange adopt taper fit.
In sum, the utility model has the following advantages:
1, bearing block floats and is fixed on the bracket of supporting bearing base by the utility model, makes bearing block can only small size beat, thus limits the beat of whole flat head sleeve, reduces freely beating of flat head sleeve, extends flat head sleeve service life; Simultaneously bracket way moving vertically, the engagement that can realize rolling mill roll and homalocephalus axle sleeve be separated, quick-replaceable milling train.
2, homalocephalus axle sleeve of the present utility model and end-tooth ring flange adopt tapered hole fit form, can fast with changing consumable accessory.
Accompanying drawing explanation
Fig. 1 is the structural representation of milling train flat head sleeve.
Wherein, 1, external bushing; 2, lining connecting bolt; 3, neck bush; 4, bearing; 5, pressing plate; 6, connecting bolt; 7, end-tooth ring flange; 8, flat key; 9, bearing block; 10, homalocephalus axle sleeve.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, provide a kind of milling train flat head sleeve, comprise homalocephalus axle sleeve 10 and end-tooth ring flange 7, connected by flat key 8 between homalocephalus axle sleeve 10 and end-tooth ring flange 7; Be provided with the bearing block 9 driving flat head sleeve to move between homalocephalus axle sleeve 10 and end-tooth ring flange 7, offer the axis hole for changing roll, being provided with neck bush 3 in axis hole in homalocephalus axle sleeve 10, the end face of homalocephalus axle sleeve 10 is provided with external bushing 1.
The utility model puts into optimal enforcement example, homalocephalus axle sleeve 10 is fixedly connected with external bushing 1 by lining connecting bolt 2, end-tooth ring flange 7 is provided with pressing plate 5 for fixing end-tooth ring flange 7 and connecting bolt 6, prevent end-tooth ring flange 7 axial displacement, end-tooth ring flange 7 is connected with shaft coupling by bolt; Bearing block 9 floats and is fixed on the bracket of supporting bearing base 9, and bearing block 9 is provided with bearing 4, bearing block 9 and spindle carrier with the use of, bearing block 9 lower end is provided with the chain stretching device hole be connected with spindle carrier; Homalocephalus axle sleeve 10 and end-tooth ring flange 7 adopt taper fit, for convenience detach and replacing consumable accessory.
The interior flat side of homalocephalus axle sleeve 10 and outer flat side's matched in clearance of roll, end-tooth ring flange 7 is by the flange connect of end-tooth, bolt and shaft coupling, and shaft coupling rotates, and drives whole flat head sleeve synchronous revolving.Bracket support bearing block 9, make bearing block 9 can only small size beat, thus prevent flat head sleeve from significantly beating, bearing block 9 coordinates with homalocephalus axle sleeve 10, bearing block 9 is floated and is fixed on bracket simultaneously, by bracket axle to way moving, the engagement that can realize rolling mill roll and homalocephalus axle sleeve 10 be separated, quick-replaceable milling train.
Because milling train replacement frequency is high, homalocephalus axle sleeve 10 adopts matched in clearance with coordinating of rolling mill roll, simultaneously neck bush 3 and external bushing 1 coordinate with roll respective face concentricity and ensure gap uniformity, and homalocephalus axle sleeve 10 connects with rolling mill roll and adopts deltiod formula, can quick dismounting rolling mill.Homalocephalus axle sleeve 10 and end-tooth ring flange 7 adopt tapered hole (axle) fit form, can fast with changing consumable accessory; Bracket passes through constraint bearing block 9 thus limits the beat of whole flat head sleeve, reduces freely beating of flat head sleeve, can increase the service life.
Although describe in detail detailed description of the invention of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
