Abstract

The utility model discloses a split type Thordon bearing which is arranged in a bearing seat and comprises a bearing main body, a bearing bushing and a bearing cover, wherein the bearing bushing and the bearing cover are sheathed on the bearing main body, are respectively designed to adopt split type and are respectively fixed with the bearing seat through screws. Key slots are axially and respectively arranged at the combined position of two half bearing bushings and the combined position of two half bearing covers. Keys for connecting the bearing bushing and the bearing cover are respectively arranged in the key slots. As the bearing bushing and the bearing seat are fixed by the screws and the keys in a connecting way, tapping is not needed on the bearing bushing, thereby not only reducing the tapping quantity and being convenient for manufacturing as well as replacing, but also being beneficial for interchanging of the bearing bushing. In addition, the bearing bushing and the bearing seat can be spread outwards by the keys, so that the bearing bushing can be closely matched with the inner wall of the bearing seat.

Description

Divide half Shi Sailong bearing

Technical field

The utility model relates to bearing, more particularly, relates to a kind of branch half Shi Sailong bearing.

Background technique

See also shown in Fig. 1, Fig. 2, divide half Shi Sailong (Thordon) bearing 10 to comprise body 11 and bearing bush 12, bearing bush 12 is designed to branch half formula, and two half bearings lining 121 closes up and is enclosed within on the body 11.This bearing 10 with the mounting type of bearing support 1 is: the position (arranging multiple spot) that needs tapping is located in line more on bearing support 1 earlier, then bearing 10 is located in the bearing support 1, according to carrying out tapping to bearing bush 12, be screwed into corresponding screw 13 at last and make bearing bush 12 and bearing support 1 fix again.For the imperial bearing of match,, therefore, when water pump keeps in repair, all must check the abrasion condition of bearing bush 12, and it is changed because bearing bush 12 is a vulnerable part.So the design of bearing 10 must meet these two primary conditions of installation for convenience detach and convenient, in addition, bearing 10 also must have good interchangeability.But, all be to adopt manual line to come tapping because existing bearing 10 is fixed with bearing support 1, can't accurately locate the tapping position, make bearing bush 12 between a plurality of bearing supports 1, to exchange.In addition, closely cooperate, need to adopt the screws 13 of arranging multiple spots (arriving 14 rows) to fix more, increased the workload of making and overhauling greatly for making bearing bush 12 and bearing support 1 inwall.

The model utility content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of branch half Shi Sailong bearing, and this bearing can make things convenient for its making and replacing.

For achieving the above object, the utility model adopts following technological scheme:

This divides half Shi Sailong bearing to be located in the bearing support, comprise bearing body, be sheathed on bearing bush and bearing cap on the body, bearing bush and bearing cap all are designed to branch half formula, axially have keyway in merging place of two half bearing linings and merging place of two half bearing lids, be provided with the key of connection bearing lining and bearing cap in the keyway, pass bearing support by screw and fix with corresponding key.

Described screw is two rows, each corresponding row's screw on each key.

In technique scheme, branch half Shi Sailong bearing of the present utility model is located in the bearing support, comprise bearing body, be sheathed on bearing bush and bearing cap on the body, bearing bush and bearing cap all are designed to branch half formula, and fix by screw and bearing support respectively, axially have keyway in merging place of two half bearing linings and merging place of two half bearing lids, be provided with the key of connection bearing lining and bearing cap in the keyway.Owing to adopt screw and key to be fixedly connected between bearing bush and the bearing support, need not tapping on bearing bush, not only reduced tapping quantity, be convenient to making and replacing, but also help the exchange of bearing bush.In addition, by bond energy is enough bearing bush and bearing support are outwards strutted, thereby more closely be matched with the bearing support inwall.

Description of drawings

Fig. 1 is the installation cross-sectional schematic of the branch half Shi Sailong bearing of prior art;

Fig. 2 is the radially cross-sectional schematic of the bearing bush of prior art;

Fig. 3 is the installation cross-sectional schematic of branch half Shi Sailong bearing of the present utility model;

Fig. 4 is the radially cross-sectional schematic of bearing cap of the present utility model.

Embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also shown in Fig. 3～4, branch half Shi Sailong bearing 20 of the present utility model is basic identical with prior art, equally also is located in the bearing support 1, comprises bearing body 21 and the bearing bush 22 that is sheathed on the body 21, bearing bush 22 is designed to branch half formula, comprises the half bearing lining of two merging.Unlike the prior art be, this bearing 20 also comprises is located at the bearing cap 23 that is sheathed on the body 21, bearing cap 23 also is designed to branch half formula, comprises the half bearing lid 231 of two merging.Have keyway 24 respectively vertically in merging place of two half bearing linings and merging place of two half bearing lids 231, and in keyway 24, be provided with the key 25 of connection bearing lining 22 and bearing cap 23, two half bearing linings and two half bearing lids 231 outwards can be strutted by key 25 is set, make bearing bush 22 and bearing cap 23 all can be closely tied on bearing support 1 inwall.And with key 25 corresponding bearing supports 1 on carry out tapping, pass bearing support 1 by screw 26 and be connected with corresponding key 25, make key 25 and bearing bush 22, bearing cap 23 all fix with bearing support 1.

Owing to adopt key 25 half bearing lining and half bearing lid 231 can be strutted, make bearing bush 22, bearing cap 23 be closely tied in bearing support 1 inwall, and fix the position of these two keys 25 by screw 26, and utilize frictional force between bearing bush 22, bearing cap 23 and the bearing support 1, can prevent that bearing bush 22 and bearing cap 23 from rotating with axle.And row's number of screw 26 only needs and corresponding two rows of key 25 quantity, and promptly each corresponding row's screw 26 gets final product on each key 25.So, in working process, even can have certain size difference between a plurality of bearing supports 1 and bearing bush 22, the bearing cap 23, but tapping is only finished on key 25, bearing bush 22, bearing cap 23 all can conveniently exchange, not only reduce preparation process, and greatly facilitated the maintenance and the replacing of bearing vulnerable part.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model the above embodiment's variation, modification.
