Description
Technical field
The utility model relates to a kind of measurement mechanism of motor, relates in particular to the measurement mechanism in a kind of electric machine rotor gap.
Background technology
The adjustment of rotor air gap is a motor, especially large-sized rolling mills, synchronous motor, turbodynamo etc. install and maintenance in an important process, the accuracy requirement height, error generally is controlled at ± 5% in.Therefore need carry out repeated measurement, calculating when adjusting, this workload is very big.The method of measuring the electric machine rotor gap commonly used is to survey between rotor with long clearance gauge insertion motor, because large-scale synchronous motor rotor air gap is bigger, usually reach 20mm to 60mm, the feeler leaf number that uses during measurement is very many, elasticity is bigger between some feeler leaves, therefore the survey measurements that influence is actual causes the incident that motor is installed or service work is done over again to happen occasionally; And need add and subtract clearance gauge thickness sheet repeatedly when measuring with long clearance gauge, extremely inconvenient, inefficiency.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of measurement mechanism that can measure the electric machine rotor gap accurately, easily.
For solving the problems of the technologies described above, electric machine rotor gap measuring apparatus of the present utility model comprises pedestal, slide block and movable rod, pedestal is the strip box-like body that goes up the plane opening, described box-like body two medial surfaces are provided with the tilt slide of plane symmetry from bottom to top, described box-like body rear end face has through hole, the front end face opening, described slide block is a rectangular T type piece, described T type piece waist both sides have with described pedestal in the tip chute of slide rail coupling, described slide block moves forward and backward in pedestal by the chute of slide block and the slide rail of pedestal, the width of described slide block upper surface is consistent with the width of described pedestal, described slide block rear end face is provided with handle, described movable rod is the round bar of two sections flexible connections, and the one end penetrates the through hole of pedestal rear end face, and the handle of the other end and slide block rear end face flexibly connects;
The described pedestal rear end face through hole outside is provided with a hollow circular tube, and described hollow circular tube tube wall is provided with screw, and described screw is screwed with fastening bolt.
The described movable rod end that penetrates pedestal rear end face through hole is provided with handle.
The same side of described pedestal and slide block indicates indicating graduation respectively.
Because electric machine rotor gap measuring apparatus of the present utility model has adopted technique scheme, this device is inserted between electric machine rotor, promote movable rod, the drive slide block skids off, and tightens the set bolt of pedestal rear end, takes out this device, read scale on pedestal and the slide block and can obtain gap numerical value between electric machine rotor, utilize this device can be accurately, be convenient for measuring the electric machine rotor gap, reduced and done over again, improved work efficiency.
