Abstract

The utility model discloses an oilless bearing bush for a ship, and relates to the technical field of bearing bushes. The oilless bearing bush comprises semi-cylindrical bush bodies, wherein the two bush bodies form a cylindrical bearing bush body; the bush body is made of metal; a plurality of axial elongated slots are formed in an inner wall of the bush body; a plurality of axial strip-shaped bulges are formed on an outer wall of a hollow cylindrical teflon self-lubricating body; the bulges are sleeved with the elongated slots in an inserting manner; the outer wall of the teflon self-lubricating body is contacted with the inner wall of the bush body; the inner wall of the teflon self-lubricating body is matched with a shaft; retainer rings are arranged on two end surfaces of the bush body; and the two retainer rings lean against two end surfaces of the bush body and the teflon self-lubricating body. The oilless bearing bush comprises the bush body made of the metal and the polymer self-lubricating body, the installation is simple, and the oilless bearing bush has good thermal conductivity and rigidity; and at the same time, the polymer self-lubricating body can be replaced conveniently, and the service life of the whole bearing bush is prolonged.

Description

A kind of peculiar to vessel without oily bearing shell

Technical field:

The utility model relates to the bearing shell technical field, and what be specifically related to is a kind of peculiar to vessel without oily bearing shell.

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 some polymer self-lubricating bearings is that integral body is polymerizable material and makes, it has light weight, insulation, antifriction, wear-resisting, selflubricating, corrosion-resistant, moulding process simple, the manufacturing efficiency high, that its deficiency is: because integral body is polymerizable material, the reasons such as its poor rigidity, poor thermal conductivity make its working life short, simultaneously, and due to polymer bearing shell poor rigidity, just easily damage during installation, install inconvenient.

The model utility content:

The purpose of this utility model is exactly the deficiency for prior art, and provide a kind of peculiar to vessel without oily bearing shell, it is comprised of watt body and the polymer self-lubricating body of metal material, it installs simple, there is good thermal conductivity and rigidity, the polymer self-lubricating body can be convenient for changing simultaneously, improves the working life of whole bearing shell.

Technology solution of the present utility model is as follows:

A kind of peculiar to vessel without oily bearing shell, comprise half-terete watt of body, two watts of bodies form a columned bearing shell body, described watt of body is metal material, form a plurality of axial elongated slots on watt body inwall, on the outer wall of the teflon selflubricating body of hollow cylindrical, form a plurality of axial strip projected parts, protruding sleeve is in elongated slot, the outer wall of teflon selflubricating body contacts with a watt body inwall, and the inwall of teflon selflubricating body matches with axle; Two end faces of watt body are provided with back-up ring, and two back-up rings are pressed against on two end faces of watt body and teflon selflubricating body.

Described elongated slot and protruding cross section are odontoid, and elongated slot and projection match.

Form a plurality of screws on two end faces of described watt of body, back-up ring is bolted on the both ends of the surface that are fixed on watt body.

The beneficial effects of the utility model are:

1, it passes through at metal tile body upper sleeve teflon selflubricating body, during use, axle is directly rubbed with teflon selflubricating body, after teflon selflubricating body damages, can reinstall teflon selflubricating body gets on, it has improved the working life of bearing shell, has reduced cost.

2, its teflon selflubricating body cost is low, can substitute other metal materials, and simultaneously, because a watt body is metal material, it has guaranteed thermal conductivity and the rigidity of bearing shell.

3, its teflon selflubricating body convenient disassembly, as long as back-up ring is unloaded, just can promote teflon selflubricating body by axially having unloaded down, very convenient.

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 side view of the present utility model;

The structural representation that Fig. 3 is teflon selflubricating body of the present utility model;

The structural representation that Fig. 4 is of the present utility model watt of body.

In figure: 1, watt body; 11, elongated slot; 12, screw; 2, teflon selflubricating body; 21, projection; 3, back-up ring; 10, bearing shell body.

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, a kind of peculiar to vessel without oily bearing shell, comprise half-terete watt of body 1, two watts of bodies 1 form a columned bearing shell body 10, described watt of body 1 is metal material, form a plurality of axial elongated slots 11 on watt body 1 inwall, form a plurality of axial strip projected parts 21 on the outer wall of the teflon selflubricating body 2 of hollow cylindrical, projection 21 sleeves are in elongated slot 11, the outer wall of teflon selflubricating body 2 contacts with watt body 1 inwall, and the inwall of teflon selflubricating body 2 matches with axle; Two end faces of watt body 1 are provided with on two end faces that 3, two back-up rings 3 of back-up ring are pressed against watt body 1 and teflon selflubricating body 2.

The cross section of described elongated slot 11 and projection 21 is odontoid, and elongated slot 11 and projection 21 match.

Form a plurality of screws 12 on two end faces of described watt of body 1, back-up ring 3 is bolted on the both ends of the surface that are fixed on watt body 1.

Working principle: two watts of bodies 1 are merged and form a bearing shell body 10, teflon selflubricating body 2 is inserted in bearing shell body 10, then by bolt, back-up ring 3 is fixed on two end faces of watt body 1, two back-up rings 3 are pressed against on two end faces of watt body 1 and teflon selflubricating body 2.Also can be back-up ring 3 unloaded after when changing teflon selflubricating body 2 simultaneously, release replaceable, very convenient by teflon selflubricating body 2.

And, in the time of the more difficult installation of some axial ratio, also can unload back-up ring 3, teflon selflubricating body 2 first is installed on axle its integral installation in watt body 1 again.
