Abstract
The utility model discloses a sliding bearing which comprises an outer bushing (1) internally provided with an inner bushing (2) made from a wearable material; an inner hole of the inner bushing (2) is provided with an alveolate oil storing hole. As the inner bushing is made from the wearable material, polyimide gas, and is processed to be alveolate by an etcher, thereby increasing the oil storing volume of the inner bushing, preventing the inner bushing and a shaft from generating dry friction, improving the lubricating performance of the sliding bearing, reducing the abrasion of the sliding bearing, lowering the working temperature of the sliding bearing and improving the service life of the sliding bearing.
Description
Technical field
The utility model relates to a kind of bearing, a kind of especially sliding bearing.
Background technique
In mechanical transmission, use a kind of sliding bearing through regular meeting, it is directly to contact with rotatingshaft, and axle is rotated in sliding bearing.The existing glide bearing comprises the overcoat on the equipment of being installed in and the interior cover of supporting shaft.Transmission shaft is located by interior cover, and rotates in interior cover.Prior art is to open some lubrication grooves at the interior inner cylindrical surface of interior cover, utilizes the lubricant oil in the lubrication groove to be lubricated, to reduce the temperature of transmission wearing and tearing and reduction bearing.But along with machine driven system requires more and more higher to each part.Existing lubricating structure can not satisfy modern mechanical high speed and long-life requirement.
The model utility content
The purpose of this utility model is, a kind of sliding bearing is provided.Can improve the lubricity of sliding bearing, reduce the wearing and tearing of sliding bearing, reduce the operating temperature of sliding bearing, improve the working life of sliding bearing.
The technical solution of the utility model: a kind of sliding bearing, comprise overcoat, in overcoat, be provided with interior cover, in apply mechanically with polyimide and make; In the endoporus of interior cover, establish cellular oil storage hole.
In the above-mentioned sliding bearing, establish annular groove in the endoporus of described overcoat.
In the aforesaid sliding bearing, described high-abrasive material is a polyimide.
Compared with prior art, the utility model is because interior cover adopts the high-abrasive material polyimide to make, and will in apply mechanically etching and be machined to cellular, the oil reserve of cover in can improving, cover produces dry friction with axle in preventing, improves the lubricity of sliding bearing, reduces the wearing and tearing of sliding bearing, reduce the operating temperature of sliding bearing, improve the working life of sliding bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: cover in the 1-overcoat, 2-, 3-annular groove.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as the foundation of the utility model being done any restriction.
Embodiment.A kind of sliding bearing, as shown in Figure 1.Comprise overcoat 1, cover 2 in overcoat 1, being provided with, interior cover 2 usefulness high-abrasive materials are made; In the endoporus of interior cover 2, establish cellular oil storage hole.Establish annular groove 3 in the endoporus of overcoat 1.Described high-abrasive material is a polyimide.
Specifically add man-hour, elder generation's car system overcoat 1, mutually nested as a whole in order to overlap 2 in helping with overcoat 1, some annular grooves 3 of car in the endoporus of overcoat 1, then with mould with polyimide material die casting in overcoat, earlier pre-car endoporus on polyimide material, cover 2 in forming, with special warfare the inner cylindrical surface of interior cover 2 is etched into cellular structure then, again inner cylindrical surface is finish-machined to the size of necessary requirement at last.
Claims (3)
1. sliding bearing, it is characterized in that: comprise overcoat (1), be provided with interior cover (2) in overcoat (1), interior cover (2) is made with high-abrasive material; In the endoporus of interior cover (2), establish cellular oil storage hole.
2. sliding bearing according to claim 1 is characterized in that, establishes annular groove (3) in the endoporus of described overcoat (1).
3. sliding bearing according to claim 2 is characterized in that, described high-abrasive material is a polyimide.
