Abstract
The invention discloses a tapered roller bearing retainer structure, which comprises an inner ring (1), a small retainer washer (2), a small roller (3), a large retainer washer (4), a large roller (5) and a supporting post (6), wherein the large roller (5) is connected on the small retainer washer (2) and the large retainer washer (4) through the supporting post (6); and the small roller (3) is integrally welded with the small retainer washer (2) and the large retainer washer (4). The tapered roller bearing retainer structure is simple, safe and reliable and has low cost; and by the structure, the rigidity of a roller bearing retainer is improved, the storage space of a lubrication meson is enlarged, the quality of an extra-large roller bearing product is improved and the service life of the extra-large roller bearing product is prolonged.
Description
Technical field
The invention belongs to metallurgical important key equipment, relate in particular to a kind of tapered roller bearing retainer structure.
Background technique
Whole world iron and steel metallurgy factory, the blast furnace distributor, the steelmaking converter tilting mechanism, the hot-rolled strip production line capital equipment includes slab caster, bar plate heating stove, constant width machine, roughing mill, themal winding box, flying shears, finish rolling tandem rolling unit, extra large size bearing equipment in the retarders such as coiling machine, all using super-huge roller bearing with first-class visual plant, special key equipment revolution part requires the reliably high especially of bearing, but use extra large size bearing roller cage unreasonable structure at global metallurgical works, because extra large size bearing roller cage unreasonable structure causes damage of bearings more frequent, therefore super-huge roller bearing retainer structure is changed.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, cost is low, safe and reliable tapered roller bearing retainer structure.
The technological scheme that the present invention is adopted for achieving the above object is: a kind of tapered roller bearing retainer structure, comprise inner ring (1), retainer small washer (2), small roller (3), retainer large washer (4), large roller (5) and pillar (6), described large roller (5) is connected on retainer small washer (2) and the retainer large washer (4) by pillar (6), described small roller (3) and retainer small washer (2) and the integrally welded structure of retainer large washer (4).
Described small roller (3) is a hollow-core construction.
Described small roller (3) is installed on the inner ring (1) jointly with retainer small washer (2) and retainer large washer (4).
Described large roller (5), pillar (6), retainer small washer (2) and retainer large washer (4) are installed on the inner ring (1) jointly.
A kind of tapered roller bearing retainer structure of the present invention, simple in structure, cost is low, and is safe and reliable, not only improves roller bearing retainer rigidity, and increases lubricated meson storage space, improves super-huge roller bearing quality of product and working life.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a kind of tapered roller bearing retainer of the present invention architecture schematic representation.
Among the figure: 1, inner ring; 2, retainer small washer; 3, small roller; 4, retainer large washer; 5, large roller; 6, pillar.
Embodiment
As shown in Figure 1, tapered roller bearing retainer structure of the present invention, comprise inner ring 1, retainer small washer 2, small roller 3, retainer large washer 4, large roller 5 and pillar 6, described large roller 5 is connected on retainer small washer 2 and the retainer large washer 4 by pillar 6, described small roller 3 and retainer small washer 2 and retainer large washer 4 integrally welded structures, small roller 3 is the hollow-core construction roller, small roller 3 is installed on the inner ring 1 jointly with retainer small washer 2 and retainer large washer 4, large roller 5, pillar 6, retainer small washer 2 and retainer large washer 4 are installed on the inner ring 1 jointly, the present invention will remove one in every row roller, increase the hollow small roller that diameter is smaller in same position, small roller and large washer, small washer is integral by being welded to connect, not only improve roller bearing retainer rigidity by this structure, and increase lubricated meson storage space, improve super-huge roller bearing quality of product and working life.
