Abstract
Provided is a split tapered roller bearing. The split tapered roller bearing belongs to the technical field of an antifriction bearing. The split tapered roller bearing comprises cone rolling bodies, half outer rings which are formed axially in a split mode, half inner rings, half retaining frame seats, half retaining frame covers, a first screw and so on. The split tapered roller bearing is characterized in that the cone rolling bodies are arranged in opposite pockets between the half retaining frame seats and between the half retaining frame covers in an embedded mode, each half retaining frame seat and each half retaining frame cover are connected by the first screw in a fastening mode and are combined into a half round cone rolling body retaining frame assembly, each half retaining frame seat shaft is arranged in a concave-convex shape towards a split surface, and a second screw is connected with two sides of the split surface on each half retaining frame seat shaft through a connecting plate in a fastening mode to combine into a round cone rolling body retaining frame assembly. A concave groove is arranged in the outer surface at two ends of each half inner ring, a clamping ring is arranged inside the concave groove in an embedding mode, the clamping ring comprises two half round annularity, joint positions are connected by a third screw in a fastening mode, and the two half inner rings are combined into a whole. The split tapered roller bearing is compact in structure, convenient to assemble and disassemble, and convenient to use in equipment with a complicated structure or a long shaft.
Description
Technical field
The utility model relates to a kind of rolling bearing, specifically is a kind of subdivision tapered roller bearing.
Background technique
Present used tapered roller bearing almost is integrated type, on some bulky baroque equipment, particularly when major axis is changed bearing, associated components must be pulled down could install, time-consuming very inconvenience.Existing subdivision tapered roller bearing structure is few, and it adopts the snap ring connecting plate to connect the two halves strut type retainer, can only be suitable for the extremely low occasion of rotating speed.
Summary of the invention
The utility model has overcome the dismounting inconvenience of integrated type tapered roller bearing and the lower problem of column support type subdivision tapered roller bearing rotating speed in the prior art, provides a kind of and can be convenient to dismounting, can satisfy again the subdivision tapered roller bearing that has higher rotation speed to require.
The employing technological scheme is: the subdivision tapered roller bearing, comprise semi outer rings that circular cone rolling element, axial subdivision form, half inner ring, partly keep stand, half retainer lid and the first screw, it is characterized in that: described circular cone rolling element is flush-mounted in described partly the maintenance in the pocket hole corresponding between stand and the described half retainer lid, described the first screw is located between adjacent two described circular cone rolling elements, described the first screw partly keeps stand and described half retainer to cover tightly being solidly connected, becoming semicircle circular cone roller holder assembly with described.The described stand axial subdivision face that partly keeps is made as concavo-convex, be convenient to two semicircle circular cone roller holder assemblies, be fastenedly connected in the described stand axial subdivision face both sides that partly keep by the second screw by connecting plate, become circular circular cone roller holder assembly.Have groove on the outer surface at described half inner ring two ends, be embedded with the clamp ring of two described half inner rings of locking in the groove, this clamp ring is two semi-annular shapes of 180 °, and its connecting part is connected by the 3rd screw fastening, makes two described half inner rings become an annulus.Circular circular cone roller holder assembly places between the annulus of annulus that two described semi outer rings consist of and two described half inner ring formations.
The beneficial effects of the utility model are: this bearing structure is compact, and is flexible for installation, is convenient to maintenance, time saving and energy saving, solved on the bulky baroque equipment or the difficult problem of major axis upper bearing (metal) dismounting.

Fig. 1 is the utility model cross section view.
Fig. 2 is two and half maintenance stand connection diagrams.
Fig. 3 is that the A-A of Fig. 1 is to cross section view.
Embodiment
Subdivision tapered roller bearing as shown in Figure 1 comprises circular cone rolling element 3, the semi outer rings 1 that axial subdivision forms, half inner ring 2, partly keeps stand 4 and half retainer lid the 5 and first screw 6.Circular cone rolling element 3 is flush-mounted in half and keeps in the pocket hole of correspondence between stand 4 and the half retainer lid 5, the first screw 6 is located between adjacent two circular cone rolling elements 3, the first screw 6 will partly keep stand 4 and half retainer lid 5 to be fastenedly connected, and become semicircle circular cone roller holder assembly; Have groove on the outer surface at half inner ring, 2 two ends, be embedded with the clamp ring 7 of locking half inner ring 2 in the groove, this clamp ring 7 is two semi-annular shapes of 180 °, and its connecting part is fastenedly connected by the 3rd screw 8, makes two and half inner rings 2 become an annulus; Partly keep stand 4 axial subdivision faces to be made as concavo-convex 11 such as Fig. 2, be convenient to two semicircle circular cone roller holder assemblies, by connecting plate 9 by the second screw 10 partly keeping stand 4 axial subdivision faces 11 both sides to be fastenedly connected, become circular circular cone roller holder assembly.Circular circular cone roller holder assembly places between the annulus of annulus that two semi outer rings 1 consist of and two and half inner rings, 2 formations.
Example: 3500 heavy and medium plate mills, 8000 kilowatts of drive motor power, 45 tons of universal driving spindle gross weights, 60～150 rev/mins of rotating speeds.The all-direction supporting bearing adopts subdivision cone rolling of the present utility model, bearing bore diameter d=680mm, bearing outside diameter D=970mm, bearing width B=400mm, under the installation of satisfying technical requirements and operating conditions, obtained comparatively desirable effect after coming into operation: more existing technological scheme, cost 20%, disassembly and assembly time has reduced 60%.
