CN202433195U - Detection tool for contact status of bearing bush body and tile sleeve cooperation spherical surface - Google Patents

Abstract

The utility model discloses a detection tool for the contact status of a bearing bush body and a tile sleeve cooperation spherical surface, which comprises a bracket used for supporting a bearing, a cross of which the center is provided with a screw, and a horizontal lever with a thread head, wherein the bracket is provided with a horizontal tabletop; a detected bearing is fixed on the table top; four end parts of the bracket are respectively provided with a bolt through hole; one end surface of a tile body is provided with four process screws which are circumferentially evenly distributed; the four process screws correspond to four bolts on the cross; the cross is tightly fixed on the end surface of the tile body by the bolts; the thread head of the horizontal lever is screwed in the center screw of the cross; and the free end of the lever is hung with a weight. In the detection tool with the above structure, the contact status of the bearing bush body and tile sleeve spherical surface can be checked by calculating the moment of the lever so as to achieve a purpose of judging the swinging freedom degree of the rotor.

Description

A kind of bearing liner body cooperates sphere contact condition inspection frock with a watt cover

Technical field

The utility model relates to the bearing verifying attachment, is specifically related to a kind of radial support removable metal body and contacts the inspection frock with a watt cover sphere, is used to check the contact condition of this sphere.

Background technology

In order to strengthen the axial adjustment degree of freedom of radial support sliding bearing, become sphere to contact with the registration interface designs of watt cover the bearing liner body, this bearing is mainly used in the occasion that allows to be supported the rotor axial swing, for example turbine rotor.

But this bearing influences the axial wobble degree of freedom of rotor because factors such as mismachining tolerance, use distortion cause contacting the sphere bite easily, causes the temperature drift of radial journal bearing tile fragment, and the tile kilning accident takes place easily, has reduced the radial journal bearing reliability.Also do not check at present the isolated plant of this sphere contact condition, give and make, overhaul this bearing and bring difficulty.

Summary of the invention

The purpose of the utility model provides an a kind of bearing liner body and watt special tooling of cover sphere contact condition checked, can check out easily that whether this sphere contacts well, has or not bite.

Technical scheme is:

A kind of bearing liner body cooperates sphere contact condition inspection frock with a watt cover, comprise

A support that is used for spring bearing, this support have a level table, are examined bearing fixing on this table top;

The cross of a center band screw; Four ends of cross have a screw perforation respectively, on end face of watt body, are provided with four circumferential equally distributed technology screws; Corresponding with four screw perforations on the cross, said cross is fastened on this watt body end face by the screw handle;

The horizontal lever of a threaded head, its thread head is screwed onto in the center screw of cross, the free end of this lever suspension counterweight.

The technique effect of the utility model:

The inspection frock of said structure, can through the moment of calculating lever examine watt body and watt cover sphere contact condition, reach the purpose of judging the swing degree of freedom.

Description of drawings

Fig. 1 is the structure diagram of this frock;

Fig. 2 is that the A of Fig. 1 is to view.

Embodiment

Referring to Fig. 1, Fig. 2, this frock comprises:

A support 1 that is used for spring bearing, this support 1 has a level table 2, is examined bearing fixing on this table top 2;

The cross 3 of a center band screw; Four ends of cross 3 have a screw perforation respectively; On end face of watt body; Be provided with four circumferential equally distributed technology screws, corresponding with four screw perforations on the cross 3, said cross 3 is fastened on this watt body end face by 5 on screw;

The horizontal lever 4 of a threaded head, its thread head is screwed onto in the center screw of cross 3, the free end of this lever 4 suspension counterweight 10.

The method of application of this frock:

Earlier second of bearing liner cover 6 is fixed on the level table 2 of support 1 with screw 8, watt body 7 of packing into, cover watt overlap 6 first, hold bolt 9 to mandrel then;

5 on cross 3 usefulness screws are fastened on the end face of this watt body 7;

Be installed in horizontal lever 4 on the cross 3;

Free end at horizontal lever 4 adds counterweight 10, when horizontal lever 4 beginnings are downward-sloping, stops to add counterweight 10;

Calculate lever moment according to lever length and counterweight weight; Judge that with the size of this moment bearing liner cover 6 cooperates the contact condition of sphere with watt body 7; So that when cooperating the loose contact of sphere; In time repair, guarantee that the sphere that contacts of watt body and watt cover can be free to slide along with the variation of operating mode when operate as normal, adapt to rotor axial and swing.

Claims (1)

1. a bearing liner body cooperates sphere contact condition inspection frock with a watt cover, comprises

A support that is used for spring bearing, this support have a level table, are examined bearing fixing on this table top;

The cross of a center band screw; Four ends of cross have a screw perforation respectively, on end face of watt body, are provided with four circumferential equally distributed technology screws; Corresponding with four screw perforations on the cross, said cross is fastened on this watt body end face by the screw handle;

The horizontal lever of a threaded head, its thread head is screwed onto in the center screw of cross, the free end of this lever suspension counterweight.
