Embodiment 1：
In order to solve the defect of cold mill complex roll bearing lubricating system existing at present and corresponding roll assembling structure,
What the present invention provided a kind of use self sealss bearing as shown in Figure 1 rolls roll assembly device.Self sealss bearing is newly to go out in recent years
A kind of existing bearing, is equipped with lip-type packing between the Internal and external cycle of bearing two ends, it is ensured that the lubricating grease of Bearing inner prepackage
Will not leak outside, greatly improve the lubricating efficiency of bearing, reduce lubrication cost.It is adapted for use with the assembling of cold mill complex roll
On.
A kind of use self sealss bearing rolls roll assembly device, including roll 1, self sealss bearing 4, gland 8 and transparent cover 2,
Described roll 1 is solid steel rider, and in the shaft shoulder position of roll 1 groove is provided with, and the roll 1 is provided with bearing block 5, self sealss
Bearing 4 is arranged on bearing block 5, and self sealss bearing 4 is located in the groove on roll 1；Described transparent cover 2 puts together on bearing block
Survey in 5；The bottom of the bearing block 5 position corresponding with the both sides of self sealss bearing 4 is respectively provided with a waist type long through-hole；Described pressure
Lid 8 puts together on the inner side of transparent cover 2 using bolt, and there is oil sealing cover 10 in the described outside of bearing block 5 conjunction.
In cold-rolled process.The bottom of bearing block 5 position corresponding with the both sides of self sealss bearing 4 is respectively provided with a waist type length and leads to
Hole can flow out the emulsion for penetrating into, and finally, and self sealss bearing 4 carries sealing, can further prevent emulsion
