Abstract

The utility model discloses a replaceable marine bearing bush for a self-lubricator, and relates to the technical field of bearing bushes. The replaceable marine bearing bush comprises a semi-cylindrical bearing bush body (1), wherein a plurality of annular grooves (2) are formed inside the bearing bush body (1); the plurality of annular grooves (2) are formed parallel to one another; polytetrafluoroethylene sliding blocks (3) are arranged inside the grooves (2). According to the replaceable marine bearing bush, the polytetrafluoroethylene sliding blocks serving as self-lubricators can be replaced, so that the service life of the bearing bush is prolonged, and pollutions such as oil stain can be avoided.

Description

The replaceable bearing shell peculiar to vessel of a kind of selflubricating body

Technical field:

The utility model relates to the bearing shell technical field, and what be specifically related to is the replaceable bearing shell peculiar to vessel of a kind of selflubricating body.

Background technique:

Self oiling bearing is divided into the composite material self-lubricating bearing, the solid embedded self-lubricating bearing, the bimetallic material self oiling bearing, the special material self oiling bearing, be widely used in metallurgy conticaster, roll firm equipment, in mining machinery, boats and ships, steam turbine, water turbine, injection machine and device fabrication production line.At present, bearing shell in most of self oiling bearing is all to be solid embedded self-lubricating body bearing shell, substantially with hole or groove shape, inlay, in the time of the axle high speed rotating, solid lubricant in hole or groove shifts or reverses and move to rubbing surface, on rubbing surface, form lubricated good, the solid transfer film of firm attachment uniform fold, decrease fretting wear, its deficiency is: when the loss of solid tesserae is complete, whole bearing shell has been scrapped, unrenewable, and some bearing shell institute solid tesserae is graphite, during operation, have plumbago out, around can making, polluted.

The model utility content:

The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of selflubricating body replaceable bearing shell peculiar to vessel, and it can change the teflon slide block as the selflubricating body, extends the working life of bearing shell, and without pollutions such as greasy dirts.

Technology solution of the present utility model is as follows:

The replaceable bearing shell peculiar to vessel of a kind of selflubricating body, comprise half-terete bearing shell body, forms many annular grooves in described bearing shell body, and many annular grooves are parallel to each other; In groove, be provided with the teflon slide block.

Described teflon slide block is to form an annular protrusion on a teflon cylinder ring outer wall, and annular protrusion is embedded in groove, and the outer wall of teflon cylinder ring is pressed against on bearing shell body inwall; The adjacent end face of the teflon cylinder ring of adjacent two teflon slide blocks is in contact with one another.

On described bearing shell body, the dual-side place forms respectively along the radially extended gulde edge of bearing shell body.

In described bearing shell body, form three annular grooves, the annular protrusion of three teflon slide blocks is embedded in three grooves, the upper-end surface of the teflon cylinder ring of middle teflon slide block contacts with the lower end surface of the teflon cylinder ring of the teflon slide block of top, and the lower end surface of the teflon cylinder ring of middle teflon slide block contacts with the upper-end surface of the teflon cylinder ring of the teflon slide block of below.

The beneficial effects of the utility model are:

1, it is by inlaying a plurality of teflon slide blocks on the bearing shell body, during use, axle directly rubs with the teflon slide block, after the teflon slide block damages, can unload and reinstall the teflon slide block and get on, it has improved the working life of bearing shell, has reduced cost.

2, its teflon slide block adopts polytetrafluoroethylmaterial material, and it has resistant to elevated temperatures characteristics, and friction factor is extremely low, reduces the energy consumed on bearing shell in the axle High Rotation Speed, and without pollutions such as greasy dirts.

The accompanying drawing explanation:

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the perspective view of bearing shell body of the present utility model;

Fig. 3 is the perspective view of teflon slide block of the present utility model;

Fig. 4 is overall structure schematic diagram of the present utility model.

Embodiment:

The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

Embodiment: see shown in Fig. 1 to 4, the replaceable bearing shell peculiar to vessel of a kind of selflubricating body, comprise half-terete bearing shell body 1, forms many annular grooves 2 in described bearing shell body 1, and many annular grooves 2 are parallel to each other; In groove 2, be provided with teflon slide block 3.

Described teflon slide block 3 is to form an annular protrusion 32 on teflon cylinder ring 31 outer walls, and annular protrusion 32 is embedded in groove 2, and the outer wall of teflon cylinder ring 31 is pressed against on bearing shell body 1 inwall; The adjacent end face of the teflon cylinder ring 31 of adjacent two teflon slide blocks 3 is in contact with one another.

On described bearing shell body 1, the dual-side place forms respectively along the radially extended gulde edge 11 of bearing shell body 1.

In described bearing shell body 1, form three annular grooves 2, the annular protrusion 32 of three teflon slide blocks 3 is embedded in three grooves 2, the upper-end surface of the teflon cylinder ring 31 of middle teflon slide block 3 contacts with the lower end surface of the teflon cylinder ring 31 of the teflon slide block 3 of top, and the lower end surface of the teflon cylinder ring 31 of middle teflon slide block 3 contacts with the upper-end surface of the teflon cylinder ring 31 of the teflon slide block 3 of below.

Working principle: at first the bearing shell body 1 of below is just put, then the annular protrusion of the below of three teflon slide blocks 3 32 is embedded in three grooves 2, and then the bearing shell body 1 of top is put down, the annular protrusion 32 of the top of three teflon slide blocks 3 is embedded in three grooves 2 in the bearing shell body 1 of top, Here it is whole complete bearing shell, after the teflon slide block 3 as the selflubricating body damages, upper and lower two bearing shell bodies 1 can be fit into new teflon slide block 3 just can continue to have used again after damaged teflon slide block 3 is separated.
