Abstract
The utility model discloses a gradient oil-containing bearing. The porosity density in the radius direction has gradient change in a round ring shape, namely, the porosity of the inner surface of a hole is large, and the porosity of the outer surface of the gradient oil-containing bearing is small; the porosity density in the axial direction has gradient change, namely, the porosity in the middle is large, and the porosity at both ends of the gradient oil-containing bearing is small. The utility model is particularly suitable for the operating mode which is larger load, and simultaneously, runs in a high speed. The gradient oil-containing bearing has the advantages of reasonable structure, easy manufacture, obvious superior performance to various oil-containing bearings in the prior art, convenient operation, easy installation and simple repair; the gradient oil-containing bearing can enhance the carrying capacity of the oil-containing bearings. The utility model can be used in all the fields in which the oil-containing bearings are used at present such as the domestic appliances of electric fans, washing machines, etc. and the occasions needing to use the gradient oil-containing bearings such as textile machinery equipment, etc.
Description
Technical field
The utility model relates to a kind of gradient oil-impregnated bearing.
Background technique
The bearing capacity of existing oil-impregnated bearing is lower, and in order to improve the bearing capacity of oil-impregnated bearing, former people adopted the design of change degree of permeability oil-impregnated bearing.Become the degree of permeability oil-impregnated bearing to the requirement of strictness is arranged between the circumferential position of the installation of bearing and the loading direction that bears.
Summary of the invention
The purpose of this utility model is to provide a kind of gradient oil-impregnated bearing, is to have the more oil-impregnated bearing of high bearing capacity.
The technological scheme that its technical problem that solves the utility model adopts is: the void density at the oil-impregnated bearing radial direction is circular graded structure, and promptly the internal surface hole rate in hole is big and little in oil-impregnated bearing outer surface porosity ratio; The void density of oil-impregnated bearing axial direction changes structure in gradient, and is promptly big and little in the porosity ratio at oil-impregnated bearing two ends in middle porosity ratio.
The useful effect that the utlity model has is: the porosity in this oil-impregnated bearing is a graded.Be specially adapted to the operating mode of big load and while high speed operation.This oil-impregnated bearing is rational in infrastructure, makes easyly, and its performance obviously is better than all kinds of oil-impregnated bearings of prior art.The gradient oil-impregnated bearing can improve the bearing capacity of oil-impregnated bearing, still has use, easy for installation, advantage easy to maintenance simultaneously.The gradient oil-impregnated bearing has great practical value for the bearing capacity and the applying of oil-impregnated bearing of further improving oil-impregnated bearing, and has the excellent development economic value.Adopting the applied field of oil-impregnated bearing all can use at present.Household electric appliance such as electric fan, washing machine for example, textile manufacturing machine equipment etc. need to use the occasion of oil-impregnated bearing.
Description of drawings
Fig. 1 is an axial arrangement schematic representation of the present invention;
Fig. 2 is a radial structure schematic representation of the present invention.
Embodiment
The axial arrangement of gradient oil-impregnated bearing 1 as shown in Figure 1, the porosity ratio in the gradient oil-impregnated bearing 1 is not uniform.Little, big in the porosity ratio of the axial intermediate portion of gradient oil-impregnated bearing near gradient oil-impregnated bearing 1 two ends porosity ratio.To the centre, the porosity ratio of gradient oil-impregnated bearing 1 changes from low to high in gradient from gradient oil-impregnated bearing two ends.The low porosity at gradient oil-impregnated bearing two ends plays the effect of oil sealing in the using process of gradient oil-impregnated bearing, thereby has reduced the oil leak of gradient oil-impregnated bearing, has improved the bearing capacity of gradient oil-impregnated bearing.
The radial structure of gradient oil-impregnated bearing 1 as shown in Figure 2, the porosity ratio in the gradient oil-impregnated bearing 1 is not uniformly, but big near the porosity ratio in the gradient oil-impregnated bearing 1 internal surface bearing, and is low in the porosity ratio at the radially-outer surface place of gradient oil-impregnated bearing 1.At radial direction from the inner surface to outer surface, the porosity ratio of gradient oil-impregnated bearing 1 changes from high to low in gradient.Near gradient oil-impregnated bearing 11 internal surfaces porosity ratio provides oil storage, and the radially porosity ratio reduction gradually from inside to outside of gradient oil-impregnated bearing has limited the oil return effect of gradient oil-impregnated bearing in the fluid lubrication pressure area; Improved the bearing capacity of gradient oil-impregnated bearing.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
Claims (1)
1, a kind of gradient oil-impregnated bearing is characterized in that: the void density at gradient oil-impregnated bearing (1) radial direction is circular graded structure, and promptly the internal surface hole rate in hole is big and little in gradient oil-impregnated bearing outer surface porosity ratio; Void density at gradient oil-impregnated bearing (1) axial direction changes structure in gradient, and is promptly big and little in the porosity ratio at gradient oil-impregnated bearing two ends in middle porosity ratio.
