Abstract

The utility model discloses a dismountable guide bearing which comprises a guide bearing seat (1), a bushing (2), a bearing bush (3), a screw (4) and a water flow hole (6). The dismountable guide bearing is characterized in that the bushing (2) and the bearing bush (3) are machined into a whole so as to be taken as a dismountable part of the guide bearing; the internal hole surface of the guide bearing seat (1) and the external hole surface of the bushing (2) have the same taper; and the guide bearing seat (1) is mechanically connected with the bushing (2). In the utility model, the modularization and small-batch production of the bushing and the bearing bush in the factory are realized, the aim of facilitating the machining and replacing of the bearing bush is achieved, the field maintenance time of a motor is shortened, and the maintenance cost of the motor is reduced greatly.

Description

A kind of detachable guide bearing

Technical field

The utility model relates to the bearing means field of motor, particularly a kind of guide bearing of large diving motor.

Background technique

The guide bearing of submersible motor mainly plays the effect of support guide rotor.When rotor contacts with bearing,, form the performance of boundary lubrication, increase wear resistance, prolong electrical machinery life etc., the bearing shell that special material is made is installed at the guide bearing endoporus in order to prevent adhesion.

In the existing technology, in order to guarantee guide bearing endoporus and outer concentricity of detaining, bearing support and bearing shell adopt integrated processing, the concentric link of accent in the middle of reducing.After bearing shell damaged, guide bearing must return factory and keep in repair on lathe or change.

Along with the lifting of submersible electrical power, the volume and the weight of its supporting part increase day by day.In a single day bearing shell damages, and above-mentioned integral processing method has exposed following drawback: guide bearing heaviness, transportation difficulty; Guide bearing is big, and the depot repair time is long; Cause maintenance cost to improve.

Summary of the invention

The purpose of this utility model provides a kind of detachable guide bearing at existing deficiency in the above-mentioned prior art just.It has detachably, engineering time is short, reduce the advantage that maintenance and cost of production, realization modularization are produced, and is particularly suitable for the large diving motor.

The purpose of this utility model can realize by following technique measures:

A kind of detachable guide bearing that the utility model provides comprises guide shaft bearing, bearing shell, lining and screw.

Aforesaid bearing shell is designed to cylindrical shape, and lining is to be processed by interior round external conical shape backing and special flange, and guide shaft bearing inner hole surface is identical tapering face with the outer hole of lining face, is processed with the screw corresponding with lining on the guide shaft bearing.

Aforesaid bearing shell and lining are processed as one as the removable section of guide bearing.

As preferably, aforesaid lining is connected by screw with the guide shaft bearing; Can also add pin or key by between.

As preferably, aforesaid bearing shell endoporus is processed as straight trough or spiral chute.

Aforementioned tapering size is good with the dismounting that makes things convenient for lining;

The number of aforementioned screw, screw, key, pin is determined by the intensity that guide bearing bore;

The beneficial effects of the utility model are as follows:

A kind of detachable guide bearing of the present utility model has been realized modularization, the small lot batch manufacture in factory of bearing shell and lining; Bearing shell processing and the convenience of changing have really been reached; Shortened the field maintenance time of motor; Greatly reduce the electrical machmary maintenance cost.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Be labeled as among the figure: 1: the guide shaft bearing; 2: lining; 3: bearing shell; 4: screw; 5: main shaft; 6: water flow hole.

Arrow is that water flows into the guide bearing direction among the figure.

Embodiment

The utility model is further described below with reference to a kind of embodiment (accompanying drawing) wherein:

As shown in the figure, a kind of detachable guide bearing of the present utility model comprises guide shaft bearing 1, lining 2, bearing shell 3, screw 4.

Described guide shaft bearing 1 inner hole surface is identical tapering face with lining 2 outer hole faces.

Be processed with six of corresponding screws on described guide shaft bearing 1 and the lining 2, the two is by screw 4 mechanical connections, easy disassembly.

Described lining 2 is processed by interior round external conical shape backing and special flange.Bearing shell 3 is processed as one as the removable section of guide bearing with lining 2, can be in factory's modularization, small lot batch manufacture, and the draining scene is standby; In case bearing shell 3 damages, and lays down axle sleeve 2, on-the-spot getting final product of more renewing, the bearing shell 3 and the lining 2 of damage returns the repair in shop reason, keeps in repair quick and easy.

Described guide shaft bearing 1 middle part radially has three water flow holes 6.

Described bearing shell 3 is processed as cylindrical shape, and endoporus has axial straight trough, and the middle part radially has three water flow holes 6 corresponding with the guide shaft bearing; In main shaft 5 rotation processes, water flows into the straight trough lubricate.

The tapering size that should be pointed out that aforementioned tapering face is good with the dismounting that makes things convenient for lining; Lining 2 also can pass through key or pin mechanical connection with guide shaft bearing 1.Below all within claim scope of the present utility model.

Claims

1. detachable guide bearing, comprise guide shaft bearing (1), lining (2), bearing shell (3), screw (4), water flow hole (6), it is characterized in that: lining (2) and bearing shell (3) are processed as one as the removable section of guide bearing, guide shaft bearing (1) inner hole surface is identical tapering face with the outer hole of lining (2) face, and guide shaft bearing (1) and lining (2) pass through mechanical connection.
