The utility model provides a measure generator stator and rotor clearance instrument, its constitution includes stock (1), and the intermediate position vertical fixed connection of stock and steel pipe (2), the top symmetry of steel pipe are connected with two nuts (3), and the terminal surface of two nuts is on the coplanar with the terminal surface of steel pipe, and measuring bolt (4) are installed through the helicitic texture to the nut. The tool for measuring the gap between the stator and the rotor of the generator is characterized in that the long rod and the steel pipe are of stainless steel pipe-shaped structures, and the diameters of the long rod and the steel pipe are the same. The utility model is applied to the field of measuring the stator and the rotor of the generator.
Description
Technical Field
The utility model relates to a tool for measuring the clearance between a stator and a rotor of a generator.
Background
In installation and servicing of thermal power plants, it is often necessary to measure the gap between the stator and rotor of the generator. The existing measuring generator stator and rotor tools are not uniform, and the operation is complex. When the gauge is adopted for measurement, a detector is required to estimate the size of the gap, then the gauge with different thickness is selected to be plugged into the gap, measurement data are obtained, the measurement process is complex, the efficiency is low, and the measurement error is large. And when the generator measures the stator and rotor clearance, the rotor guard ring is blocked, so that the measurement clearance is small, the distance is long, and the arms of maintenance personnel are inconvenient to measure.
Disclosure of Invention
The utility model aims to provide a tool for measuring the clearance between a stator and a rotor of a generator.
The above object is achieved by the following technical scheme:
the utility model provides a measure generator stator and rotor clearance instrument, its constitution includes, the stock, the intermediate position vertical fixed connection of stock and steel pipe, the top symmetry of steel pipe be connected with two nuts, the terminal surface of two nuts and the terminal surface of steel pipe are on the coplanar, the nut install measuring bolt through the helicitic texture.
The tool for measuring the gap between the stator and the rotor of the generator is characterized in that the long rod and the steel pipe are of stainless steel pipe-shaped structures, and the diameters of the long rod and the steel pipe are the same.
The tool for measuring the gap between the stator and the rotor of the generator is characterized in that a handle sleeve is sleeved at the end part of the long rod.
The utility model has the beneficial effects that:
1. the utility model solves the problem that the maintainer is inconvenient to measure the gap between the stator and the rotor of the generator, and simultaneously can solve the problem that the maintainer is inconvenient to measure the arm due to small measurement gap and long distance when measuring the stator and the rotor of the motor.
2. According to the utility model, a bracket and two bolts are welded on the top of a stainless steel pipe, the gap distance between a stator and a rotor is repeatedly adjusted and measured through the bolts, after the distance is adjusted in place, the final data is measured by a vernier caliper, and the data is recorded.
3. The tool has the characteristics of simple manufacture, low material cost, accurate and effective measurement result, convenient and quick use and the like.
