Abstract
The utility model relates to a supporting structure for a guide bearing of a vertical hydraulic generator, which comprises a guide bearing seat fixedly mounted on a frame, and a guide bearing bush fixedly mounted on the guide bearing seat. The supporting structure is characterized in that the structure further comprises an adjusting wedge block positioned between the guide bearing bush and the guide bearing seat; a support pin is mounted between the guide bearing bush and the adjusting wedge block; a clearance is reserved between the adjusting wedge block and the guide bearing seat; an adjusting wedge plate matched with the adjusting wedge block is mounted in the clearance; the upper end of the adjusting wedge plate is connected with the adjusting wedge block through a screw; and an adjusting nut is assembled on the screw. Therefore, the structure has the advantages of simple structure, and convenient installation and adjustment, and can prolong the service life of the guide bearing of the hydraulic generator.
Description
Technical field
The utility model belongs to hydraulic turbine generator and makes the field, particularly relates to a kind of vertical hydrogenerator guide bearing supporting structure.
Background technique
The installation of guide bearing and support direct relation whole water turbine working efficiency and working life in hydraulic turbine generator is made, and existing Hydraulic generator pilot bearing supports by the guide bearing that is installed on upper spider and the lower bearing bracket.At present, guide bearing generally is installed in adjustment screw rod between guide shaft bearing and the guide bearing by employing, adjust be sleeved on the screw rod conform to a conventional pattern on, by the adjustment of adjusting screw rod being guaranteed the mounting point of guide bearing.Bear at hydraulic turbine generator under the situation of big radial load, said structure guide bearing fluctuation of service, so this structural-load-carrying capacity is little, it is inconvenient to adjust, and also the bush gap swing is big, causes the working life of Hydraulic generator pilot bearing low.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, install easy to adjust and can improve the Hydraulic generator pilot bearing vertical hydrogenerator guide bearing supporting structure in working life.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of vertical hydrogenerator guide bearing supporting structure, comprise the guide shaft bearing that is packed on the frame, install the guide bearing on the guide shaft bearing, it is characterized in that: also comprise the adjustment voussoir between guide bearing and guide shaft bearing, the support pin of installing between guide bearing and the adjustment voussoir, leave the gap between described adjustment voussoir and the guide shaft bearing, the adjustment wedge that installation and adjustment voussoir cooperate in the gap, the upper end of adjusting wedge connects by screw rod adjusts voussoir, the equipped nut of adjusting on the screw rod.
The utility model can also adopt following technical measures:
Described support pin is made as sphere near adjusting the voussoir end.
Between described guide shaft bearing and guide bearing, support pin and the guide bearing felt pad is installed also.
Described adjustment wedge is made as L shaped.
The corresponding wedge place that adjusts has through hole on the described guide shaft bearing lower end sheet.
Advantage and the good effect that the utlity model has are: owing to be provided with the adjustment voussoir between guide bearing and guide shaft bearing, the end face of installing between guide bearing and the adjustment voussoir is the support pin of sphere, adjusting voussoir like this contacts with sphere with support pin, when generator set moves, allow the direction swing of guide bearing along the guide bearing rotation; Adjust between voussoir and the guide shaft bearing and leave the gap, in the gap, install and adjust the adjustment wedge that voussoir cooperates, adjust the upper end of wedge and adjust voussoir by the screw rod connection.Make that by the adjustment nut of adjusting on the screw rod adjusting wedge compresses the adjustment voussoir, adjust voussoir power is passed to the sphere support pin, reach the purpose of adjustment; In addition, be provided with felt pad between guide bearing and sphere support pin and guide shaft bearing, to cut off shaft current, effectively preventing tile kilning phenomenon produces, thus said structure simple, install working life easy to adjust and that can improve Hydraulic generator pilot bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, guide shaft bearing; 1-1, through hole; 1-2, lower end sheet; 2, guide bearing; 3, support pin; 4, adjust nut; 5, screw rod; 6, adjust wedge; 7, adjust voussoir; 8, felt pad.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, adjust voussoir 7 owing between guide bearing 2 and guide shaft bearing 1, be provided with, between guide bearing 2 and the adjustment voussoir 7 support pin 3 that end face is a sphere is installed, adjusting voussoir 7 and support pin 3 like this contacts with sphere, when generator set moves, allow the direction swing of guide bearing 2 along the guide bearing rotation; Adjust between voussoir 7 and the guide shaft bearing 1 and leave the gap, the adjustment wedge 6 that cooperates with the wedge surface of adjusting voussoir 7 is installed in the gap, adjustment wedge 6 is made as L shaped, is the formation that guarantees to adjust wedge 6, and guide shaft bearing 1 lower end sheet 1-2 goes up corresponding adjustment wedge 6 places and has through hole 1-1.The upper end bending part of adjusting wedge 6 connects by screw rod 5 adjusts voussoir 7, adjusts the equipped nut 4 of adjusting in two ends of wedge on screw rod 5.Make that by the adjustment nut of adjusting on the screw rod 54 adjusting wedge 6 compresses adjustment voussoir 7, adjust voussoir 7 power is transmitted sphere support pin 3, reach the purpose of adjustment like this; In addition, be provided with felt pad 8 between guide bearing 2 and sphere support pin 3 and guide shaft bearing 1, to cut off shaft current, effectively preventing tile kilning phenomenon produces.
Adjusting method: at first the nut of wedge lower end is adjusted in turn, screw the nut of adjusting the wedge upper end again, this moment nut will drive the adjustment wedge move down, the wedge surface of voussoir is adjusted in the wedge surface extruding of meanwhile adjusting wedge, adjust voussoir and by support pin power is passed to guide bearing, when adjusting suitable position, the adjustment nut at wedge two ends is adjusted in locking, finish whole adjustment process like this, so said structure is simple, it is easy to adjust to install and working life that can improve Hydraulic generator pilot bearing.
