Abstract
The utility model relates to an inserted light hydrogen-cooled turbo-generator sealed tile. A concave end surface at one end of a basal body is matched with a convex end surface of a sealed body. The concave end surface and the convex end surface are fixedly connected in a whole through a fastening thread line. An oil pipe is respectively arranged in a hydrogen side oil hole and an air side oil hole on the sealed body by utilizing the basal body. The utility model has the advantages of light integral weight, good tightness, non-damage of shafts, safe utilization and long service life.
Description
The utility model belongs to a kind of generator sealing bearing bush, mainly is that prior art constructions has been done improvement.
The existing generator sealing bearing bush that generally uses, it mainly adopts the matrix of steel material as sealing bearing bush, and circle is hung with bearing metal (babbit) in it, fits in one by being arranged in section for the oat tail groove structure form.The sealing bearing bush body weight is big, the golden body of tungsten is easy to wear because of in use having, hinder shortcomings such as axle and leakiness hydrogen, make it for a long time, and be the insoluble problem in thermal power plant always.
The purpose of this utility model is for solving the problem that above-mentioned technology exists, and a kind of lightweight hydrogen sealing bearing bush is provided.
For achieving the above object, technical solution of the present utility model is finished like this: a kind of sealing bearing bush, by in empty side seal oilhole and hydrogen-side seal oil hole, oil pipe being set respectively on matrix and the seal, making matrix one end is that recessed end face cooperates with the convex surface that seal has, and is integral by horizontal lock screw is fixedly connected.
Feature of the present utility model comprises that also the recessed end face of matrix and the convex surface of seal scribble bond layer.
The utility model has following advantage compared to existing technology:
1, adopting aluminum alloy materials is the mosaic mode that matrix and composite material seal utilize convex-concave, has simple in structurely, in light weight, can be 1/4 of original sealing bearing bush weight.
2,, can avoid leaking between two combinations phenomenon of hydrogen, good seal performance by being distributed with oil pipe in empty side on matrix and seal and the hydrogen-side seal oil hole.
3, form because of seal adopts polytetrafluoroethylene, microballon, graphite, copper powder compounded die casting, proportion is 2.1 kilograms/cubic centimetre overcoat, can prevent to hinder axle.
Do concrete description below in conjunction with accompanying drawing embodiment.
Fig. 1 is the structural representation of sealing bearing bush.
By shown in Figure 1, inserted lightweight hydrogen sealing bearing bush, adopting the light aluminum alloy material is cylindrical watt matrix 3, interior nose circle by matrix 3 has recessed end face, with within the seal 1 of composite material of nose circle face configuration, by the convex surface that has on it convex-concave of two bodies is cooperated, make to apply on two counterfaces that bond layer 6 is inlayed and by lock screw 2 fixedly connected being integral; According in empty side seal oilhole that has on 1 and the hydrogen-side seal oil hole sealing oil pipe 5 and 4 being set respectively, make the interior nose circle face conducting of sky side oilhole and hydrogen side oilhole and seal 1 by watt matrix 3 and sealing.
Claims (2)
1, inserted lightweight hydrogen sealing bearing bush, comprise that sealing bearing bush matrix and seal constitute one, by it sky side seal oilhole and hydrogen-side seal oil hole are set respectively, it is characterized in that, described sealing bearing bush matrix (3) one ends are that recessed end face cooperates with the convex surface that seal (1) has, and, make oil pipe (5,4) composition is set respectively in sky side oilhole and the hydrogen side oilhole by fixedly connected being integral of lock screw (2).
2, by the described sealing bearing bush of claim 1, it is characterized in that the convex surface of the recessed end face of described watt of matrix (3) and seal (1) scribbles bond layer (6).
