Detailed Description
In order to make the aforementioned features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to FIGS. 1 and 2
The utility model provides an air gap measuring device between generator rotor, stator, includes bracing piece 10, the upper end of bracing piece transversely is provided with fixed cover 20, horizontal spiro union has thimble screw rod 30 on the fixed cover, the spiro union has lock nut 40 that is used for locking thimble screw rod on the thimble screw rod to after thimble screw rod has adjusted length, lock through lock nut. The working end of the thimble screw has a rectangular block 31 for rotating the thimble screw so that the thimble screw is rotated by the rectangular block to adjust the projecting length of the thimble screw.
In this embodiment, for the working range of the different degree of depth of better use, the bracing piece is the telescopic link. The support rod comprises a sleeve 11 with a holding end part at the lower end, a telescopic rod part 12 with the upper end connected with the fixed sleeve is arranged on the sleeve in a penetrating mode, and a locking threaded sleeve 13 used for locking the telescopic rod part is connected to the upper end of the sleeve in a threaded mode, so that telescopic adjustment is completed.
In this embodiment, for better stretching into the air gap between generator rotor, the stator, be provided with arcwall face 32 on the rectangular block, fixed cover is provided with arcwall face 21 on keeping away from the terminal surface of rectangular block.
In this embodiment, in order to guarantee the joint strength between fixed cover and the bracing piece, fixed cover welds with the bracing piece mutually.
The using method comprises the following steps: and adjusting the extension length of the ejector pin bolt, adjusting the length of the supporting rod, and extending the measuring device into a gap between the motor stator and the motor rotor. If the gap between the motor stator and the motor rotor is larger than or smaller than the distance from the end face of the rectangular block to the other end (the end with the arc face) of the fixed sleeve, the measuring device is taken out, the extending length of the supporting rod is adjusted again until the extending length of the ejector pin bolt is enough to measure the distance between the motor stator and the motor rotor, then the measuring device is taken out, the distance from the end face of the rectangular block to the other end (the end with the arc face) of the fixed sleeve is measured, and the obtained data is the distance length between the motor stator and the motor rotor. Usually, the distance between the motor stator and the motor rotor can be measured by adjusting the extending length of the ejector pin bolt for 3-5 times, and then the gap between the motor stator and the motor rotor is adjusted through the measured distance. The measuring device greatly improves the measuring speed and reduces the workload.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
