Abstract
The utility model relates to a roller four-row cylindrical bearing for a steel rolling machine. The bearing comprises outer ferrules, an outer lantern ring, outer retaining rings, rollers, a retainer and an inner ferrule, wherein the number of the outer ferrules is two, the outer lantern ring is mounted between the two outer ferrules, and the outer lantern ring is in the shape of a circular ring. The outer retaining rings are shaped like circles, and the outer retaining rings are arranged on the outer sides of the two outer ferrules for blocking the rollers. Each roller is in the shape of a cylinder with a hole at the middle, the rollers and the corresponding retainer are mounted together through a shaft pin, the retainer is of two thin circular sheets with shaft pin holes, and the rollers and the retainer are mounted between the outer ferrules and the inner ferrule. The inner ferrule is in the shape of a cylinder, and the inner ferrule is arranged on a shaft of the rolling machine. The roller four-row cylindrical bearing has the advantages of reasonable mounting structure and convenience in mounting, cleaning and maintenance, and can bear heavier radial load, increase the number of the rollers to the greatest extent and fundamentally eliminate the phenomenon that a roller path is scratched due to driving of the rollers from an outer ring gap.
Description
Technical field
The utility model belongs to the milling train field that is used for rolling metal strip, relates to a kind of roll rolling bearing that is used for rolling mill, and especially a kind of rolling mill is with roll four row's cylindrical bearings.
Background technology
Present stage, the rolling-mill roller rolling bearing has replaced the bakelite tile supporting, makes rolling speed and precision that large increase all arranged; But, roll also has a very big problem after adopting rolling bearing; Be exactly the thrust bearing neither one version preferably also of roll, such as: double-row angular contact bal bearing, this class bearing have two row rolling elements; Width is bigger; Suit under the medium axial load condition of high speed, to work, because of its can only one when bearing axial force row stressed, so its ability of bearing axial load is little.Such as double-row conical bearing, such bearing axial load is bigger again, but in use has a lot of shortcomings, and 1. limit speed is low, can not be suitable for high-speed rolling; 2. roller large end face and centre rib are sliding frictions, and when moment, axial force was very big, burn very easily appearred in bearing; 3. such bearing width size is very big, takies very large space of bearing housing, and the volume of bearing housing is increased; 4. not only bearing radial force but also when bearing axial force of this class bearing and since its inner ring can not with roller footpath tight fit, seize, excessively heated axle phenomenon appear when rolling easily, this is the deficiency of existing milling train with thrust bearing.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art; Design a kind of rolling mill with roll four row's cylindrical bearings; This bearing can bear heavier radial load; Can increase the quantity of roller to greatest extent, and fundamentally eliminate the phenomenon that raceway scratches, in order to overcome the deficiency of existing milling train with bearing.
The utility model is realized through following technical scheme:
This bearing is made up of outer collar, outer sleeve, outer back-up ring, roller, retainer and inside race, and outer collar is a cylindrical shape, and it radially has the oilhole through hole; The through hole inwall has annular boss; Outer collar has two, between two outer collar outer sleeve is installed, and outer sleeve is an annular.Outer back-up ring is a ring shape, and outer back-up ring is located at the outside of two outer collar, in order to the retaining roller.Roller is middle with holes cylindrical, and roller is installed together with corresponding retainer through axle Xiao, and retainer is the thin circle sheet in two tape spool Xiao holes, and roller, retainer are installed between outer collar and the inside race.Inside race is a cylindrical shape, and inside race supplies on the milling train axle, to install.
The beneficial effect of the utility model:
The utility model has the advantages that rational in infrastructure; Installation, cleaning, easy to maintenance; Can bear heavier radial load, can increase the quantity of roller to greatest extent, and can fundamentally eliminate because roller is squeezed into the phenomenon of the scuffing raceway that brings from the outer shroud breach.
Description of drawings
Fig. 1 arranges the cylindrical bearing planes for this rolling mill with roll four.
Among the figure, 1 is that outer collar, 2 is that outer sleeve, 3 is that outer back-up ring, 4 is that roller, 5 is that retainer, 6 is that inside race, 7 is that through hole, 8 is Xiao.
The specific embodiment
Specify according to 1 pair of the utility model of accompanying drawing below
Fig. 1 is the overall structure cutaway view of the utility model.
As shown in Figure 1; This milling train is made up of outer collar 1, outer sleeve 2, outer back-up ring 3, roller 4, retainer 5 and inside race 6 with bearing, and outer collar 1 is a cylindrical shape, and it radially has oilhole through hole 7; Through hole 7 place's inwalls have annular boss; Outer collar 1 has two, between two outer collar 1 outer sleeve 2 is installed, and outer sleeve 2 is an annular.Outer back-up ring 3 is a ring shape, and outer back-up ring 3 is located at the outside of two outer collar 1, in order to retaining roller 4.Roller 4 is middle with holes cylindrical, and roller 4 is installed together with corresponding retainer 5 through axle Xiao 8, and retainer 5 is the thin circle sheet in two tape spool Xiao holes, and roller 4, retainer 5 are installed between outer collar 1 and the inside race 6.Inside race 6 is a cylindrical shape, and inside race 6 supplies on the milling train axle, to install.
All parts of the utility model are steelwork, and it can make multi-form biserial bearing, but corresponding part will suitably increase.
