Abstract

The utility model discloses a self-lubrication body replaceable type bearing bush relating to the technical field of bearing bushes. The self-lubrication body replaceable type bearing bush comprises a semi-cylindrical bearing bush body (1), wherein multiple annular grooves (2) are formed in the bearing bush body (1), are parallel to each other, and are internally provided with polytetrafluoroethylene sliding blocks (3). The self-lubrication body replaceable type bearing bush provided by the utility model can replace the polytetrafluoroethylene sliding blocks as a self-lubrication body, the service life of the bearing bush is prolonged, and pollution such as oil pollution does not exist.

Description

The replaceable bearing shell of a kind of selflubricating body

(1) technical field

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

(2) background technique

Self oiling bearing is divided into the composite material self-lubricating bearing, solid embedded self-lubricating bearing, bimetallic material self oiling bearing, special material self oiling bearing.At present, bearing shell in most of self oiling bearing all is to be solid embedded self-lubricating body bearing shell, substantially inlay with hole or groove shape, in the time of the axle high speed rotating, solid lubricant in hole or the groove moves to rubbing surface transfer or counter-rotating, form lubricated good at rubbing surface, the solid transfer film of firm attachment and 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, has plumbago during operation out, polluted around can making.

(3) 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, and it can change the teflon slide block as the selflubricating body, prolongs 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 of a kind of selflubricating body comprises half-terete bearing shell body, forms many annular grooves in the described bearing shell body, and many annular grooves are parallel to each other; Be provided with the teflon slide block in the groove.

Described teflon slide block is to form an annular protrusion on the teflon cylinder ring outer wall, and annular protrusion is embedded in the groove, and the outer wall of teflon cylinder ring is pressed against on the 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.

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

Form three annular grooves in the described bearing shell body, 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 at the bearing shell body, axle directly rubs with the teflon slide block during use, 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 that consumes on bearing shell in the axle High Rotation Speed, and without pollutions such as greasy dirts.

(4) description of drawings

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 representation of the present utility model.

(5) embodiment

The following stated only is 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 that the replaceable bearing shell of a kind of selflubricating body comprises half-terete bearing shell body 1, forms many annular grooves 2 in the described bearing shell body 1, many annular grooves 2 are parallel to each other; Be provided with teflon slide block 3 in the groove 2.

Described teflon slide block 3 is to form an annular protrusion 32 on a teflon cylinder ring 31 outer walls, and annular protrusion 32 is embedded in the 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.

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

Form three annular grooves 2 in the described bearing shell body 1, 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 32 with the below of three teflon slide blocks 3 is embedded in three grooves 2, and then the bearing shell body 1 of top 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, can just can continue to have used with newer teflon slide block 3 being fit into after two bearing shell bodies 1 are separated from the teflon slide block 3 of breakage up and down.
