Abstract

A sliding bearing adopts the structure that a sliding bearing bushing is embedded in a sliding bearing seat; the outer side of a sliding bearing shaft sleeve is connected with the inner side of the sliding bearing bushing; the sliding bearing bushing is positioned on the sliding bearing seat through an I-shaped pin; and bear plates are arranged at the ends of the sliding bearing shaft sleeve, and a layer of resin material is coated on the surface of each bear plate. The bearing has a simple design structure, the outer side of the sliding bearing shaft sleeve and the inner side of the sliding bearing bushing are matched each other to form a friction pair, and a plurality of uniformly-arranged round holes filled by a carbon fiber composite material are formed on the sliding bearing bushing so as to ensure that the lubricating material forms a continuous lubricating layer on the bearing friction surface. Therefore, the service life of the bearing is greatly prolonged.

Description

A kind of sliding bearing

Technical field

The utility model relates to a kind of bearing, concrete relates to a kind of sliding bearing that is applied under the low-speed heave-load working condition.

Background technique

The utility model relates to bearing and makes the field, and concrete is to be applied under the low-speed heave-load working condition, or the sliding bearing a kind of simple in structure at the running position of maintaining and filling lubricant oil difficulty.Traditional sliding bearing adopts graphite bigger as the direct friction loss between lubriation material and sliding bearing and the outside rotating shaft more, and noise that easy generation is bigger and vibration influence the working life and the manufacturing efficiency of bearing.

Summary of the invention

In view of the defective that prior art exists, the purpose of the utility model is to provide a kind of friction factor little, and wear-resisting property is good, the sliding bearing that greasy property is strong.

For realizing above-mentioned purpose, the technical solution that the utility model adopted mainly is to be made up of plain bearing housing, sliding bearing axle bush, sliding bearing axle sleeve and I shape pin.

A kind of sliding bearing; It is characterized in that: sliding bearing axle bush insert is in plain bearing housing; The sliding bearing axle sleeve outside links to each other with the sliding bearing axle bush is inboard; The I shape pin is positioned the sliding bearing axle bush on the plain bearing housing, in the end of sliding bearing axle sleeve carrier is set, and carrier external coating one deck resin material.

Have a plurality of circular ports of evenly arranging on the said sliding bearing axle bush, the filling carbon fiber composite material is a lubriation material in the hole.

After adopting such scheme, compare with existing bearing and the utlity model has following beneficial effect:

1, has a plurality of circular ports by the carbon fiber composite filling of evenly arranging on the sliding bearing axle bush of the utility model; Can guarantee that lubriation material forms the continuous lubrication layer all the time on the pivot friction surface; Improved the working life of bearing greatly, and advantages such as carbon fiber composite has that friction factor is little, the selflubricating ability strong, Wear-resistant, high-temperature resistant.

2, the utility model project organization is simple; The sliding bearing axle sleeve outside and the sliding bearing axle bush inboard formation friction pair that can coincide; And the end at the sliding bearing axle sleeve is provided with carrier, has prolonged the axial carrying capacity of sliding bearing, thereby improves the working life of bearing.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: 1, plain bearing housing, 2, the sliding bearing axle bush, 3, the sliding bearing axle sleeve, 4, the I shape pin, 5, carrier.

Embodiment

A kind of sliding bearing; It is characterized in that: sliding bearing axle bush 2 inserts are in plain bearing housing 1; Sliding bearing axle sleeve 3 outsides and 2 inboard linking to each other of sliding bearing axle bush; I shape pin 4 is positioned sliding bearing axle bush 2 in the end of sliding bearing axle sleeve 3 carrier 5 to be set on the plain bearing housing 1, and carrier 5 external coating one deck resin materials.

Said plain bearing housing 1 can be selected low carbon steel or stainless steel-like metallic material for use, and sliding bearing axle bush 2 inserts are in plain bearing housing 1, and sliding bearing axle sleeve 3 outsides and sliding bearing axle bush 2 inboards link to each other, and the formation friction pair that can coincide reduces the impaired of bearing.

Have a plurality of circular ports of evenly arranging on the said sliding bearing axle bush 2, the filling carbon fiber composite material is the lubriation material of bearing in the hole.

Said carrier 5 is positioned at the end of sliding bearing axle sleeve 3, and it is casting material that carrier 5 can be selected Cuprum alloy for use, is flexible material at the resin material of carrier 5 external coatings, can eliminate noise and vibration in the bearing operation process.

Claims

1. sliding bearing; It is characterized in that: sliding bearing axle bush (2) insert is in plain bearing housing (1); Sliding bearing axle sleeve (3) outside links to each other with sliding bearing axle bush (2) is inboard; I shape pin (4) is positioned sliding bearing axle bush (2) in the end of sliding bearing axle sleeve (3) carrier (5) to be set on the plain bearing housing (1), and carrier (5) external coating one deck resin material.

2. a kind of sliding bearing according to claim 1 is characterized in that: have a plurality of circular ports of evenly arranging on the said sliding bearing axle bush (2), the filling carbon fiber composite material is the lubriation material of bearing in the hole.
