Abstract
The utility model relates to a movable spacer ring four-row cylindrical roller bearing for a novel rolling mill, wherein movable detachable outer check rings are arranged on the two sides of a bearing outer ring; a movable detachable middle check ring is arranged at the center of the outer ring; a jaw of an open elastic check ring and the open elastic check ring matched with the jaw are arranged at the open end of a comb-shaped cage; and movable middle spacer rings are arranged between the bearing rolling elements. The bearing outer ring has a simple shape which is favorable for machining a forged piece, and reciprocating grinding can be adopted for grinding work as no flange exists in the outer fissure, thereby reducing the coarseness of the bearing and the bearing cost. The original comb-shaped cage is improved by arranging the jaw of the open flexible check ring, therefore the bearing is simple to mount and convenient to detach during the assembly of the bearing. The adoption of the movable check rings on the entire outer ring avoids problems, such as the quenching stress concentration caused by the unavoidable oil gallery and oil groove on the fixed flange, the grinding crack easily generated on the flange, and the like. The movable spacer ring four-row cylindrical roller bearing for the novel rolling mill is easy to detach and mount in the production and is convenient to check in the use.
Description
Technical field
The present invention relates to a kind of bearing.
Background technique
Roller-mill bearing often adopts four-line column roller bearing, shown in Fig. 1-4, there are three fixedly ribs (flange) this kind four-line column roller bearing outer ring, bearing roller adopts integrated type car system comb shape retainer, can not dissembling inspection and cleaning in the use, labor intensity is big, product cost is high, and the bearing dynamic load is low, can not satisfy the requirement of user to working life.
Summary of the invention
The object of the present invention is to provide and a kind ofly can reduce the bearing manufacture cost, the novel four-line column roller bearing that increases the service life.The rib of bearing of the present invention cancellation prior art lower bearing outer ring, and movable dismountable outer back-up ring is set in the both sides, outer ring, in the centre, outer ring guide ring is set.
In order to achieve the above object, a kind of novel rolling mill of the present invention spacer ring four-line column roller bearing of living, described bearing comprises outer ring 01 and inner ring 02, four-row cylindrical roller rolling element 04 is installed between outer ring 01 and the inner ring 02, rolling element 04 is wrapped with comb type retainer 06, and 01 bi-side, described outer ring are provided with outer back-up ring 11; Ring washer 61 in being provided with in the middle of the described outer ring 01; Described comb type retainer 06 opening end is provided with the opening circlip age of a draught animal and the opening circlip 09 supporting with the age of a draught animal is installed; Be provided with spacer ring 43 in the activity between the described rolling element.Described outer back-up ring 11 is movable dismounting back-up ring; Described guide ring 61 is movable dismounting back-up ring.
The invention has the advantages that the centre rib of four-row cylindrical roller outer ring makes spacer ring in the activity (being the support ring between rolling element) under the cancellation prior art.Cancellation outer ring rib makes the outer ring become bobbin, and simple shape helps the processing of forging, and outer fissure does not have rib, and grinder can adopt reciprocal grinding, thereby reduces the roughness of bearing, has reduced the bearing cost.Former comb shape retainer is improved, be provided with the opening circlip age of a draught animal, make bearing when assembling, convenient disassembly is installed simply.The sliding damper circle is all adopted in the outer ring, avoided fixing rib inevitably the quenching stress that caused of oil duct, oil groove concentrate and rib is easy to produce problems such as Grinding cracks.Product of the present invention is easy to removal and installation in the production, is convenient in the use check.

Embodiment
As shown in Figure 5, the novel rolling mill of the present invention spacer ring four-line column roller bearing of living, bearing comprises outer ring 01 and inner ring 02, and four-row cylindrical roller rolling element 04 is installed between outer ring 01 and the inner ring 02, rolling element 04 is wrapped with comb type retainer 06, and 01 bi-side, described outer ring are provided with outer back-up ring 11; Ring washer 61 in being provided with in the middle of the described outer ring 01; Described comb type retainer 06 opening end is provided with the opening circlip age of a draught animal and the opening circlip 09 supporting with the age of a draught animal is installed; Be provided with spacer ring 43 in the activity between the described rolling element.Described outer back-up ring 11 is movable dismounting back-up ring; Described guide ring 61 is movable dismounting back-up ring.
Novel rolling mill of the present invention makes spacer ring in the activity (being the support ring between rolling element) into the centre rib of four-row cylindrical roller outer ring under the spacer ring four-line column roller bearing cancellation prior art of living.Cancellation outer ring rib makes the outer ring become bobbin, and simple shape helps the processing of forging, and outer fissure does not have rib, and grinder can adopt reciprocal grinding, thereby reduces the roughness of bearing, has reduced the bearing cost.Former comb shape retainer is improved, be provided with the opening circlip age of a draught animal, make bearing when assembling, convenient disassembly is installed simply.The sliding damper circle is all adopted in the outer ring, avoided fixing rib inevitably the quenching stress that caused of oil duct, oil groove concentrate and rib is easy to produce problems such as Grinding cracks.Product of the present invention is easy to removal and installation in the production, is convenient in the use check.
The above; only be the preferable structure embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technological scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
