Abstract
The utility model relates to a four-row cylindrical roller bearing for enhanced rolling apparatuses, which is composed of an external ferrule, an external sleeve ring, an external retaining ring, rollers, retainers and an internal ferrule. The utility model is characterized in that the roller forms a cylindrical shape, and the center of the roller is provided with a hole; each roller and the corresponding retainer are connected together by pins. The utility model with the advantages of reasonable structure and convenient maintenance, installation and cleaning can bear large radial load, can increases the number of rollers at maximum, and can fundamentally eliminate the phenomenon of scratching rolling tracks; thus, the utility model is an ideal four-row cylindrical roller bearing for enhanced rolling apparatuses.
Description
The utility model relates to a kind of bearing, particularly a kind of reinforced rolling mill four-line column roller bearing.
Present milling train bearing, because retainer will occupy a large amount of spaces, the quantity that give to increase roller has been brought difficulty, but the increase of taking advantage of the power of carrying of reinforced bearing realizes by the quantity that increases roller often, and this point to be the traditional bearing difficulty realize.In addition, traditional bearing is squeezed into roller from the outer shroud breach and is realized assembling, is easy to occur the phenomenon that raceway scratches, and this is the deficiency of existing milling train with bearing.
The purpose of this utility model is a kind of reinforced rolling mill four-line column roller bearing of design, 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 purpose of this utility model can realize by following embodiment: this bearing is made up of outer collar, outer sleeve, outer back-up ring, roller, retainer and inside race, outer collar is a cylindrical shape, 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, 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 by axle Xiao and corresponding retainer, 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 is for installing on the milling train axle.
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, be a kind of desirable reinforced rolling mill four-line column roller bearing.
Be described in further detail with novel this this below in conjunction with accompanying drawing.
Fig. 1 is an overall structure cutaway view of the present 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, outer collar 1 is a cylindrical shape, 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 by axle Xiao 8 and corresponding retainer 5, 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 is for installing on the milling train axle.
All parts of the utility model are steelwork, and it can make multi-form biserial bearing, but corresponding part will suitably increase.
