Abstract
The utility model discloses a bevel wedge type guide bearing bush gap adjusting device of a water turbine. The gap adjusting device comprises a main shaft and a guide bearing bush, wherein a gap is formed between the main shaft and the guide bearing bush. The key point is as follows: the tail end of the guide bearing bush and one side of an ejector plate are fixed; a groove is formed in the other side of the ejector plate; a convex chrome steel block is clamped in the groove; the bottom surface of the convex chrome steel block is connected with the vertical surface of a beveled wedge; the bevel face of the bevel wedge is tightly attached to the bevel side of a trapezoid support bevel block; the vertical side of the trapezoid support bevel block is connected with a fixing block; the top of the bevel wedge is fixed on a connecting transverse plate through an adjusting bolt; the connecting transverse plate is fixedly connected with the fixing block and is proved with a dial indicator; the bevel face of the bevel wedge is adapted to the bevel side of the trapezoid support bevel block. The bevel wedge type guide bearing bush gap adjusting device of the water turbine is simple in principle, convenient to use, simple to operate and high in testing accuracy; the desired motion distance of the bevel wedge is determined through the obliquity ratio of the bevel wedge; the dial indicator is used for monitoring the gap between the guide bearing bush and the main shaft; manpower and material resources can be greatly saved.
Description
Technical field
The utility model relates to a kind of water turbine inclined wedge type pilot bearing regulating device.
Background technique
Hydraulic generator pilot bearing is used for stablizing main shaft center of rotation, and bearing radial force when operation must form one deck oil film position between guide bearing block and main shaft axle journal, by oil film power transmission lubricated and heat radiation.If the gap of guide bearing block and main shaft is too little, can not form oil film position, make bearing shell generation semi-dry friction even rub and burn; If pilot bearing is too large, again can not stable rotation center, the throw of main shaft is just very large.Therefore pilot bearing is adjusted extremely important.Traditional adjusting method is the gap that checks wedge and chromium steel piece with clearance gauge, is then repeatedly adjusting, and it operates more complicated, and checking precision is not high.
Model utility content
The purpose of this utility model is to provide a kind of water turbine inclined wedge type pilot bearing regulating device.
To achieve these goals, by the following technical solutions, a kind of water turbine inclined wedge type pilot bearing regulating device, comprise main shaft, guide bearing block, gapped between main shaft and guide bearing block, it is characterized in that: described guide bearing block afterbody and top board are fixing on one side, on the another side of top board, be provided with groove, in groove, card has convex chromium steel piece, and the bottom surface of convex chromium steel piece is connected with the vertical plane of wedge; The hypotenuse of the inclined-plane of described wedge and trapezoidal support skewback is close to, and the vertical edge of trapezoidal support skewback is connected with fixed block; The top of described wedge is bolted to and is connected on transverse slat by adjustment, and this connection transverse slat is fixedly connected with fixed block.
On described connection transverse slat, be also provided with dial gauge.
The hypotenuse of the inclined-plane of described wedge and trapezoidal support skewback adapts.
The utility model principle is simple, easy to use, recently determines by the gradient of wedge the distance that wedge need to move, and monitor the gap between guide bearing block and main shaft by dial gauge, it is simple to operate, can save greatly human and material resources, and testing accuracy is high.
Brief description of the drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of water turbine inclined wedge type pilot bearing regulating device, comprise main shaft 1, guide bearing block 2, gapped 3 between main shaft 1 and guide bearing block 2, described guide bearing block 2 afterbodys and top board 4 are fixing on one side, on the another side of top board 4, are provided with groove, in groove, card is established the convex portion of convex chromium steel piece 5, and the bottom surface of convex chromium steel piece 5 is connected with the vertical plane of wedge 6; The hypotenuse of the inclined-plane of described wedge 6 and trapezoidal support skewback 7 is close to, and the vertical edge of trapezoidal support skewback 7 is connected with fixed block 11; The top of described wedge 6 is fixed on connection transverse slat 9 by adjusting bolt 8, and this connection transverse slat 9 is fixedly connected with fixed block 11.
On described connection transverse slat 9, be also provided with dial gauge 10.
The hypotenuse of the inclined-plane of described wedge 6 and trapezoidal support skewback 7 adapts.
When use, calculate than (being generally 1:20) and the gap of drawing requirement the distance of determining that wedge need to move at axial position according to the gradient of wedge, then by adjusting bolt, wedge is carried out to displacement, after reaching effective height, fix, finally monitor by dial gauge, whether macro-axis is carried out smallly moving radially the gap that verification adjusts and meeting the demands.For example will adjust pilot bearing 0.20mm, the gradient of wedge is than being 1:20, wedge 4 mm that need move up.Then radial direction moves main shaft, checks pilot bearing with dial gauge.
The utility model principle is simple, easy to use, recently determines by the gradient of wedge the distance that wedge need to move, and monitor the gap between guide bearing block and main shaft by dial gauge, it is simple to operate, can save greatly human and material resources, and testing accuracy is high.
