Abstract
The invention discloses a method for checking structure adjusting range of a water turbine wedge block guide bearing. The method comprises the steps of in assembling a water turbine generator upper and lower frame guide bearing, correcting a false shaft, adjusting the false shaft to a central position and fixing by a flat-head jack, then mounting a shaft guiding tile and a wedge block in a calibration manner, and detecting a radial contact distance between the shaft guiding tile and the false shaft by means of a dial gauge; detecting a radial adjusting gap of the shaft guiding tile by means of a feeler gauge, and if the radial contact distance is equal with the radial adjusting clearance, judging a fact that the guide bearing assembling dimension is qualified. The method has advantages of simple structure, convenient operation and low cost. The method can be used for conveniently, quickly and accurately detecting the radial adjusting range of the shaft guiding tile, thereby facilitating subsequent processing and saving time and labor.
Description
Technical field
The present invention relates to a kind of inspection method, particularly a kind of inspection hydraulic turbine chock block guide bearing structure adjusting range
Method.
Background technology
At present, on hydrogenerator after the completion of the assembling of lower bearing bracket guide bearing, it is necessary to the scope radially adjusted to its guide bearing block
Quantization inspection is carried out, so in power station assembled in situ, is just avoided that guide bearing block radial direction adjusting range can not meet drawing requirement.
At this stage the assembling of lower bearing bracket guide bearing is completed in factory on hydrogenerator, and guide bearing block radial direction adjusting range is not entered
Row is concrete to be quantified to check, can only detect in power station assembled in situ, because the gradient of chock block is 1:100 or 1:50, radially
Adjusting range is very little, if not detected in maker and being handled well, after power station assembling is pinpointed the problems, processes non-
It is often difficult.
The content of the invention
It is an object of the invention to provide a kind of convenient, fast, accurate inspection hydraulic turbine chock block guide bearing structure adjustment
The method of scope.
The purpose of the present invention realizes that one kind checks hydraulic turbine chock block guide bearing structure by such technical scheme
The method of adjusting range, methods described comprises the steps：
1）Dummy shaft is corrected；Tack jack is installed in the outer wall bottom of dummy shaft, and dummy shaft radial direction position is adjusted by tack jack
Put, the cylindrical distance to frame inner wall of dummy shaft is checked in ten word directions using inside micrometer, make dummy shaft in frame inner wall
Center；
2）, school dress guide bearing block and chock block, monitor the radial displacement of guide bearing block with dial gauge；Install on the outer wall top of dummy shaft and lead
Bearing shell, correspondence guide bearing block installs the chock block with chromium steel block in guide shaft bearing, and dial gauge is arranged on into guide bearing block upper surface；First
Chock block is made to bottom offset, because the chromium steel block of chock block and guide bearing block is contact of incline plane, such guide bearing block with regard to radial displacement, hundred
The data for dividing table are exactly that guide bearing block radially contacts with the distance i.e. adjusting range of guide bearing block；
3）Chock block shifts up original position, and with clearance gauge the gap of chock block and the chromium steel block of guide bearing block, its gap are detected
It is equal that value should radially contact with distance with guide bearing block；
4）Actually detected gap width（Or guide bearing block radially contacts with distance value）It is consistent with design requirement guide bearing block radial direction adjusting range
Or be more than, guide bearing fitted position is qualified, otherwise should just check whether the size of each assembly parts is qualified.
Wherein, center error ± 0.03 millimeter of the dummy shaft in frame inner wall.
Wherein, the 2nd）In step, the original position of chock block should be 1/5 on the chock block length direction at, chock block is to bottom
Move final position should be 4/5 on chock block length direction at.
As a result of above-mentioned technical proposal, the present invention has the advantages that simple structure, easy to operate, with low cost, adopts
Can easy, fast and accurately detect guide bearing block radial direction adjusting range with it, be convenient for subsequent treatment, saved the time and
Cost.

The description of the drawings of the present invention is as follows：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the zoomed-in view of Fig. 1.
Specific embodiment
The specific embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings, but the present invention does not limit to
In these embodiments, any improvement or replacement on the present embodiment essence spirit still falls within the claims in the present invention and wants
Seek the scope of protection.
Embodiment 1：As shown in Figure 1, 2, a kind of method for checking hydraulic turbine chock block guide bearing structure adjusting range, described
Method comprises the steps：

To position, the cylindrical distance to frame inner wall of dummy shaft 1 is checked in ten word directions using inside micrometer, make dummy shaft 1 be in frame
The center of inwall；
2）, school dress guide bearing block and chock block, monitor the radial displacement of guide bearing block with dial gauge；Install on the outer wall top of dummy shaft 1
Guide bearing block 3, correspondence guide bearing block 3 installs the chock block 5 with chromium steel block 4 in guide shaft bearing 4, and dial gauge 6 is arranged on into guide bearing block 3
Upper surface；Chock block 5 is first made to bottom offset, because the chromium steel block 4 of chock block 5 and guide bearing block 3 is contact of incline plane, such guide bearing block
3 with regard to radial displacement, and the data of dial gauge 6 are exactly that guide bearing block 3 radially contacts with the distance i.e. adjusting range of guide bearing block 3；
3）Chock block 5 shifts up original position, and with clearance gauge the gap of chock block 5 and the chromium steel block 4 of guide bearing block 3 is detected, its
It is equal that gap width should radially contact with distance with guide bearing block 3；
4）Actually detected gap width（Or guide bearing block radially contacts with distance value）It is consistent with the radial direction adjusting range of design requirement guide bearing block 3
Or be more than, guide bearing fitted position is qualified, otherwise should just check whether the size of each assembly parts is qualified.
Wherein, center error ± 0.03 millimeter of the dummy shaft 1 in frame inner wall.
Wherein, the 2nd）In step, the original position of chock block 5 should be 1/5 on the length direction of chock block 5 at, chock block 5 is downward
