Abstract
The utility model discloses an end bearing seat for a pressure booster gas compressor. An inner hole of a seat body is matched with a semi floating bearing, and the axial end surface of one end of the seat body is a thrust surface matched with a thrust bearing shaft. A radial oil inlet hole is arranged on the seat wall of the seat body, the position of the radial oil inlet hole corresponds to the position of the semi floating bearing, the axial oil inlet hole is arranged on the seat wall of the seat body, and an oil outlet of the axial oil inlet hole corresponds to the thrust bearing. The end bearing seat has the advantages that the structure of the end bearing part of the pressure booster gas compressor is simplified, the production and assembly difficulty is reduced, meanwhile, the mutual interference between oil paths of the radial bearing and the thrust bearing is avoided, and the operation is safe. The end bearing seat is applicable to the installation of a pressure booster gas compressor rotor.
Description
Technical field
The utility model relates to diesel engine of locomotive and uses turbo-charger technical field, relates in particular to a kind of supercharger air compressor step bearing seat.
Background technique
At present; Inner supporting type is adopted in the supporting of turbosupercharging machine rotor, two floating bearings or semifloating bearing is arranged usually in two end supports, and the axial force of rotor leans on the end face of thrust bearing to bear; But internal combustion locomotive is with the shortcoming that turbocharger air compressor step bearing seat exists on the existing railway; Gas compressor step bearing seat does not have the effect of thrust bearing, causes the many complex structures of amount of parts, and this brings difficulty for production and assembly technology.
The model utility content
The technical problem that the utility model solved provides a kind of supercharger air compressor step bearing seat, makes it have the effect of thrust bearing simultaneously.
The technological scheme that the utility model adopts is a kind of supercharger air compressor step bearing seat, and the endoporus of pedestal and semifloating bearing are suitable, and the axial end of pedestal one end is the thrust surface that matches with lead bronze thrust bearing axle, and the thrust surface upper epidermis is a high hardness material.
The seat wall of pedestal is provided with radially oil inlet hole, and radially oil inlet hole is corresponding with the semifloating position of bearings, and the seat wall of said pedestal is provided with the axial fuel inlet hole, and the oil outlet in axial fuel inlet hole is corresponding to thrust bearing.
The beneficial effect of the utility model is a structure of having simplified supercharger air compressor step bearing part, reduces and produces assembling difficulty, still makes the oil circuit of radial bearing and thrust bearing not disturb security of operation mutually simultaneously.
Description of drawings
Fig. 1 is a pedestal longitudinal section sectional view.
Fig. 2 is the pedestal cross section view.
Fig. 3 is original supercharger air compressor step bearing structure.
Be labeled as among the figure: the 1-endoporus, the 2-thrust surface, 3-is oil inlet hole radially, 4-axial fuel inlet hole, 5-back oil road, 6-thrust backing plate, 7-oil-deflecting cover, 8-bearing housing, 9-cylinder body.
Embodiment
As shown in Figure 1, the endoporus 1 of pedestal is to cooperate with the external diameter of semifloating bearing, and pedestal has two axial end faces, and its inboard axial end is the thrust surface 2 that matches with main thrust bearing, bears the end thrust from thrust bearing.The bearing support of this practicability is given semifloating radial bearing and thrust bearing inner ring fuel feeding by radial direction respectively by oil duct arranged side by side, gives semifloating bearing fuel feeding at the radially oil inlet hole 3 that the seat wall of pedestal is offered, and the axial fuel inlet hole 4 on the seat wall is the thrust bearing fuel feeding.Guaranteed the reliability of radial bearing work, adjoined mutually with main thrust bearing that oil circuit does not disturb mutually, improved bearing and whole pressurized machine functional reliability greatly though accomplished radial bearing.
The size of oil supply: the sectional shape of axial oil groove can make rectangle, triangle, circle.The width of axial oil groove generally is according to the width-diameter ratio of bearing and flow, in 0.1D～0.3D scope, chooses.Groove depth generally is taken as 1/10 of the degree of depth.The diameter of oil supply hole is generally according to choosing by the reference oil well width.Must not there be sharp edge on the surface of oil groove and oilhole, answers rounding off to the bearing support internal surface, to reduce the flow of lubricant dynamic resistance.
Fig. 3 is original supercharger air compressor step bearing structure; The relative existing structure of the utility model has been simplified parts such as thrust backing plate 6, oil-deflecting cover 7, bearing housing 8, cylinder body 9; Reduced possibility for error; Lubricated oil circuit is more succinct, has avoided because of the lubricated bad problems such as bearing burnt that cause.
