Abstract
The utility model relates to an oil containing bearing composed of a rigid frame and an oil containing lining. The rigid frame is a ring-shaped structure made of rigid materials. The oil containing lining is a ring-shaped structure made of oil containing materials. The inner side of the oil containing lining is in a cylinder shape for installing a rotating shaft. The shape of the oil containing lining and the shape of the inner chamber of the rigid frame are coincident with each other. The oil containing lining is embedded into the inner chamber of the rigid frame to be fixedly connected into a whole. The utility model has the advantages of rub resistance, corrosion resistance, low cost and easy installation and maintenance, and can realize self-lubrication, effectively decrease the noise of products and prolong the service life.
Description
The utility model relates to a kind of oil-impregnated bearing, low speed bearing in referring to especially.
Bearing is a kind of part of extensive use in the mechanical industry, is commonly used to the axle that need rotate is installed on pedestal or the support.Now relatively more commonly used have multiple bearings such as ball bearing, roller bearing, plane bearing, thrust bearing, alignment bearing, though existing various bearing structural type is different, but they all have two-layer at least separate rigid backbone, be provided with several rolling elements between the two-layer rigid backbone, this two-layer rigid backbone can be relatively rotated, when two skeletons relatively rotate, rolling element rolls between two skeletons, because rolling friction power is far smaller than sliding friction power, so the friction when this two skeleton relatively rotates is very little, rotating shaft is rotated flexibly.The deficiency of existing plain bearing is: the multi-layer structure of bearing causes bearing inside to have certain interval, and can make above-mentioned gap enlargement because of wearing and tearing in operation process, if there is the dust foreign matter to enter bearing inside, also can quicken its wearing and tearing.Owing to there is the gap, be installed in on-stream can the generation of rotating shaft on the bearing and rock or vibrate, influence its running accuracy and produce noise.Though existing alignment bearing can reduce rocking of axle to a certain extent, and since its complex structure, the cost height, and be difficult for Installation and Debugging, so fail to be used widely.
The purpose of this utility model is to provide a kind of oil-impregnated bearing, to eliminate rocking of axle.
The technological scheme that the utility model adopted is: oil-impregnated bearing is made up of a rigid backbone and an oil-containing lining, described rigid backbone is a ring structure of being made by rigid material, the oil-containing lining is the ring structure made from the oil-containing material, its inboard is cylindrical, for rotating shaft is installed, the cavity shape of oil-containing lining profile and rigid backbone coincide mutually, and above-mentioned oil-containing lining is embedded among the inner chamber of rigid backbone and is connected to one.Described oil-containing material is the new material that has grown up since a kind of the eighties, and comparative maturity mainly contains plastic alloy etc. at present.
Advantage of the present utility model is its wear-resisting wiping, and is corrosion-resistant, cost is low, can realize selflubricating in the using process, is easy to installation and maintenance, can reduce the product noise effectively, improves life of product.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1: structural representation of the present utility model.
The described oil-impregnated bearing of present embodiment is made up of a rigid backbone 1 and an oil-containing lining 2, described rigid backbone 1 is a steel annulus, the main body of described oil-containing lining 2 is the cylinder that a usefulness plastic alloy is made, its external diameter is identical with the interior circle of skeleton 1, as shown in Figure 1, turnup is to the both ends of the surface of skeleton 1 laterally at the two ends of this oil-containing lining 2, and to strengthen the intensity of combination between the two, the oil-containing lining 2 of said structure can utilize casting method to make.For further strengthening the join strength of lining 2 and skeleton 1, to guarantee can not relatively rotate between the two, the described scheme of present embodiment also is provided with several pins 3 crimping and the skeleton 1 of lining 2 is connected as one.
Claims (3)
1, a kind of oil-impregnated bearing, it is special to be that it is made up of a rigid backbone (1) and an oil-containing lining (2), described rigid backbone (1) is a ring structure of being made by rigid material, oil-containing lining (2) is the ring structure made from the oil-containing material, the inboard of this oil-containing lining (2) is cylindrical, and the cavity shape of profile and rigid backbone (1) coincide mutually.
2, oil-impregnated bearing as claimed in claim 1, the two ends that it is characterized in that described oil-containing lining (2) laterally turnup to the both ends of the surface of skeleton (1).
