Abstract
The utility model relates to a novel middle assembly for a turbocharger, comprising a rotor (1), a middle case (4) and a compressor impeller (1), wherein the middle part of the rotor (1) is arranged in the inner hole of the middle case (4) by a floating bearing (14) and a thrust bearing (8) in a penetrating way; the right end of the rotor (1) extends out of the middle case (4); the right end of the middle case (4) is encapsulated by a sealing plate (7) and a sealing sleeve (12); the thrust bearing (8) and the sealing plate (7) are arranged on the right end of the rotor (1); the thrust bearing (8) adopts a split structure, and consists of a right thrust bearing and a left thrust bearing; the inner hole of the middle case (4) between the left and right thrust bearings (14) is provided with a steel jacket (13); the rotor (1) between the left side of the sealing sleeve (12) and the thrust bearings (14) is sleeved with a position plate (5) and a thrust plate (6); and the fitting position of the sealing sleeve (12) and the sealing plate (7) is inserted with a sealing ring (9). The utility model has the advantages of high assembly precision, good sealing property, good stability and prolonged service life of the turbocharger.
Description
(1) technical field
The utility model relates to a kind of turbosupercharger, especially relates to a kind of novel turbocharger intermediate assembly.Belong to the link technical field.
(2) background technique
The intermediate assembly that existing turbosupercharger is used generally by rotor, middle case, sealing plate, thrust bearing, seal ring, shaft end nut, impeller, stuffing box gland, floating bearing etc. form.Along with the raising of the rotational speed of rotor, because the sealing structure poor performance of above-mentioned use, the shortcoming that assembly precision is low causes pressurized machine leakage of oil, axial movement value big easily, thereby destroys the oil film that pressurized machine is set up in the running, and pressurized machine is damaged.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of good seal performance, novel turbocharger intermediate assembly that assembly precision is high are provided.
The purpose of this utility model is achieved in that a kind of novel turbocharger intermediate assembly, comprise rotor, middle case and compressor impeller, be threaded onto in the endoporus of middle case by floating bearing and thrust bearing in the middle of the described rotor, the rotor right-hand member stretches out outside the middle case, the middle case right-hand member encapsulates with sealing plate and stuffing box gland, and thrust bearing and seal plate means are on stuffing box gland, and the stuffing box gland device is on rotor, compressor impeller is installed on the rotor right-hand member
Described floating bearing adopts split-type structural, by about two floating bearings constitute, in the middle case endoporus about this between two floating bearings steel bushing is housed;
Rotor between described stuffing box gland left side and the floating bearing is set with location piece and thrust plate, and seal ring is set in stuffing box gland and sealing plate cooperation place.
The utlity model has following advantage:
1, steel bushing is formed good intermediate support structure with the floating bearing of its left and right sides, carries out the axial clearance location by middle steel bushing, and the axial clearance that guarantees intermediate is between 0.03mm～0.04mm.
2, location piece, thrust plate and thrust bearing are formed superior axial bearing structure.Sealing plate, seal ring and stuffing box gland form sealing configuration, has superior sealability.
The utility model intermediate assembly has the advantage of assembly precision height, good seal performance, good reliability, and can prolong the working life of pressurized machine.
