Background technique
Filmatic bearing is mainly used to bear rolling pressure and guarantees milling train low energy consumption stable operation in the sheet material rolling mill, and modern milling train requires filmatic bearing to have the advantages that bearing capacity is big and physical dimension is little.Existing filmatic bearing is mainly by radially bearing assembly, axial carrying assembly, mechanism for assembling-disassembling, seal arrangement and other link are formed.Radially bearing assembly is mainly tapered sleeve, lining, and tapered sleeve connects by key and roll is fixed together, and rotates synchronously with roll; Lining is assemblied on the bearing support, and is fixed by locating stud, is static element.Tapered sleeve, lining constitute fastness, and the tapered sleeve rotation is brought pressure oil into bearing play, when the working diameter of filmatic bearing, gap, bearing rotating speed, lubricating oil viscosity perfect match, form the pressure oil film to bear external load.
Tapered sleeve is a kind of conical sleeve, and its cylindrical is a working surface, and endoporus is a cone shape hole.At present, annular oil groove is offered at the middle part one in the taper hole, and many axis oil grooves vertically, working surface cylindrical are established many oilholes and communicated with oil groove.Though this structure can realize lubricating between tapered sleeve inner conical surface and the roll male cone (strobilus masculinus), reduce the stressed of the friction of both conical surfaces and connecting key, but the oilhole, the oil groove that are distributed on the tapered sleeve all have certain influence to the formation and the useful area of the oil film of filmatic bearing, and make filmatic bearing reduce bearing capacity, and, make that machining efficient is lower because axis oil groove quantity is more.
Summary of the invention
The purpose of this utility model is on the basis of existing filmatic bearing technology, in order to increase the oil film bearing conic sleeve bearing capacity, dismounting is more convenient, shape, quantity to its upper oil hole and oil groove are carried out reasonable Arrangement, simultaneously, simplify the structure of bearing, improve machining efficient, and design a kind of oil film axle with net formula oil groove tapered sleeve.
The technical solution of the utility model is achieved in that a kind of filmatic bearing with net formula oil groove tapered sleeve, by radially bearing assembly, axial carrying assembly, mechanism for assembling-disassembling, seal arrangement and other link are formed; Radially bearing assembly comprises tapered sleeve, lining, and tapered sleeve connects by key and roll is fixed together, and rotates synchronously with roll, constitutes fastness with the lining that is assemblied on the bearing support; Be characterized in tapered sleeve wall thickness D 〉=19mm, in the tapered sleeve internal circular surfaces along the circumferential direction annular be provided with some main oil grooves, pay oil groove, be provided with some axis oil grooves along axial direction, main oil groove, pair oil groove and axis oil groove interweave in length and breadth, form reticular structure and also are interconnected; The oil groove of tapered sleeve inside edge is main oil groove, is provided with several oil inlet holes that are uniformly distributed along the circumference on the tapered sleeve working surface at tapered sleeve supporting region edge and main oil groove, and oil inlet hole is connected the working surface of tapered sleeve and the main oil groove of inner conical surface.
The utility model relates to a kind of filmatic bearing with net formula oil groove tapered sleeve compared with prior art, outstanding substantive distinguishing features with significant technological progress is:
1, the oil film bearing conic sleeve inner conical surface adopts net formula oil groove, and oil inlet hole is 4 to 6, is symmetrically distributed in the loading ability of bearing area edge, has reduced the influence of load to tapered sleeve to greatest extent, and lubricant oil has certain pressure simultaneously, enables to enter oil groove by oilhole;
2, the oil groove layout of the oilhole of oil film bearing conic sleeve and inner conical surface, shape, quantity are more reasonable, and lubricant oil enters between tapered sleeve inner conical surface and the roll by oil inlet hole, netted oil groove, effectively guarantee lubricatedly therebetween, more help mounting or dismounting.
3, increase tapered sleeve bearing capacity in the filmatic bearing, simplified the structure of bearing simultaneously, improved the machining efficient of tapered sleeve greatly.
