After touching rotor surface stopping, the scale on measuring rod is read, you can complete quickly to measure the probe that rotor airgap waveform is popped one's head in
The distance between rotor is arrived in front end, easy to operate, does not need the additional operations such as mark, and do not damage generator component, improves
Measurement accuracy.
Description of the drawings
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing：
Fig. 1 is that the structure of generator amature air gap waveform probe gap measuring device in the utility model some embodiments is shown
It is intended to.
When Fig. 2 is that generator amature air gap waveform probe gap measuring device measures in the utility model some embodiments
Structural schematic diagram.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It is clearly fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than all implements
Example.
Generator amature air gap waveform is popped one's head in when mounted, and probe distal end passes through the mounting hole on fixing nut platform 3
31 extend near the border surface of rotor 2, and probe end is fixed on fixing nut platform 3.
Fig. 1 show the knot of generator amature air gap waveform probe gap measuring device in the utility model some embodiments
Structure schematic diagram.Generator amature air gap waveform probe gap measuring device includes measuring rod 1, and measuring rod 1 is threaded through fixed spiral shell
In the mounting hole 31 of female platform 3, measuring rod 1 includes front end and end, and the front end of measuring rod 1 is opposite with the border surface of rotor 2,
The end of measuring rod 1 is exposed to the outside of fixing nut platform 3, and measuring rod 1 is equipped with for measuring generator amature air gap waveform
Scale 12 of the probe distal end of probe to distance between rotor 2.
The section of measuring rod 1 can be circle, and diameter is less than the diameter of mounting hole 31, so that measuring rod 1 can be from installation
It is stretched into hole 31.The section of measuring rod 1 may be the other shapes such as rectangle, and cross dimensions is less than the section ruler of mounting hole 31
It is very little, so that measuring rod 1 can be stretched into from mounting hole 31.Preferably, the more soft copper of quality may be used in measuring rod 1
At preventing plowing from generator, other materials can also be used to be made.
The front-end surface of measuring rod 1 is curved surfaces 11, surface radian and the 2 border surface of rotor of the curved surfaces 11
Surface radian corresponds to, and when so that measuring rod 1 touching rotor 2, the front-end surface of measuring rod 1 can be pasted with the border surface of rotor 2
It closes, measure accurate and generator will not be scratched.It is to be appreciated that the front-end surface of measuring rod 1 may be other shapes.
The distance L of the dead-center position of 1 high scale 12 of measuring rod to 1 front end of measuring rod pops one's head in generator amature air gap waveform
Probe distal end to fixing nut platform 3 distance it is equal.With stretching into for measuring rod 1, measuring rod 1 is by the every mistake of dead-center position
1mm is that air gap increases 1mm.Conversely, if measuring rod 1 is moved back outward by dead-center position, it is that air gap reduces 1mm often to exit 1mm.
The end of measuring rod 1 is equipped with and shakes hands 13, to facilitate human hand to hold, measuring rod 1 is stretched by mounting hole 31, waits touching
Encounter rotor 2 stop after, directly read the numerical value on scale 12 be rotor airgap waveform probe probe distal end to rotor it
Between distance.The generator amature air gap waveform probe gap measuring device of the utility model is easy to operate, does not need mark etc.
Additional operations, and generator component is not damaged, measurement accuracy is improved, need not be compared, disposably measurement can be completed soon
The probe distal end for measuring rotor airgap waveform probe of speed is the distance between to rotor.
