Abstract

The utility model relates to a tilting-pad bearing which comprises a bearing carrier (1) and a pad (2), wherein a trapezoidal groove (5) is formed in the bearing carrier (1); a pad root (6) of the pad (2) is inserted and sheathed in the groove (5); an elastic steel strap (4) is arranged between the pad root (6) and the bottom surface of the groove (5); and two end surfaces of the bearing carrier (1) are connected with an end cover (3) through bolts. By independently manufacturing and assembling the pad and the bearing carrier, the bearing is simple in structure and convenient to disassemble and assemble, and the damaged pad can be replaced independently, so that the cost for replacing and maintaining the bearing is lower.

Description

A kind of tilting-pad bearing

Technical field:

The utility model relates to the bearing shell technical field, more specifically to a kind of tilting-pad bearing.

Background technique:

The two ends of the high pressure rotor of at present general steam turbine all adopt tilting-pad bearing, and current tilting-pad bearing is because of its complicated structure, dismounting inconvenience, the tile fragment of the tilting-pad bearing simultaneously had and bearing support are that integral body processes, when wherein a tile fragment damages, need to change whole tilting-pad bearing, cause unnecessary repair and replacement expense.

The model utility content:

The purpose of this utility model is exactly the deficiency for prior art, and a kind of tilting-pad bearing is provided, and it is simple in structure, and convenient disassembly can be changed separately the damage tile fragment, has reduced maintenance expenses.

Technology solution of the present utility model is as follows:

A kind of tilting-pad bearing, comprise bearing support and tile fragment, forms trapezoidal groove on bearing support, is inserted with watt root of tile fragment in groove, between the bottom surface of Wa Gen and groove, is provided with elastic steel sheet, on the both ends of the surface of described bearing support, has been bolted to connection end cap.

The end shape of watt root of described tile fragment is trapezoidal.

Described bearing support is comprised of several circular arc pieces.

One surface elastic of described elastic steel sheet is pressed against on the bottom surface of groove, and another side elasticity is pressed against on the plane, top of watt root.

The beneficial effects of the utility model are:

1, this bearing carries out independence manufacture and assembling by tile fragment and bearing support, and it is simple in structure, and disassembly and assembly are convenient, can change separately the damage tile fragment, the expense of low repair and replacement bearing.

The accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model;

Structural representation when Fig. 2 is end-cover-free of the present utility model.

Fig. 3 is that the utility model partly cuts open structural representation.

In figure: 1, bearing support; 2, tile fragment; 3, end cap; 4, elastic steel sheet; 5, groove; 6, watt root.

Embodiment:

Embodiment: see shown in Fig. 1,2, a kind of tilting-pad bearing, comprise bearing support 1 and tile fragment 2, form trapezoidal groove 5 on bearing support 1, be inserted with watt root 6 of tile fragment 2 in groove 5, be provided with elastic steel sheet 4 between the bottom surface of watt root 6 and groove 5, be bolted to connection end cap 3 on the both ends of the surface of described bearing support 1.

The end shape of watt root 6 of described tile fragment 2 is trapezoidal.

Described bearing support 1 is comprised of several circular arc pieces.

One surface elastic of described elastic steel sheet 4 is pressed against on the bottom surface of groove 5, and another side elasticity is pressed against on the plane, top of watt root 6.

Working principle: the bearing support 1 that several circular arc pieces form fits together by end cap 3, and tile fragment 2 can or dwindle in the interior expansion of effect step 1 of elastic steel sheet 4.Bearing support 1 and tile fragment 2 are processed separately, can directly change the tile fragment 2 of damage, without changing whole bearing.
