Abstract
The utility model discloses an alignment detection ruler for stator and rotor magnetic force centers of a motor, and solves a technical problem that no simple and convenient tool on-site for detecting alignment of the stator and rotor magnetic force centers of the motor. The detection ruler comprises a long strip base plate (3), a length calibrated scale (4) is arranged on the long strip base plate (3), a measuring fixture protruding head (2) is arranged on a measuring origin of the length calibrated scale (4), and a height (H) of the measuring fixture protruding head (2) is equal to 1.5 times of an air gap length formed between the motor stator and the motor rotor. The alignment detection ruler for the stator and rotor magnetic force centers of the motor reduces dismounting, adjusting and repairing frequency of a motor bearing, and reduces a time period of the motor occupying a testing stand.
Description
Technical field
The utility model relates to the testing tool whether align at a kind of motor stator and the magnetic force center of rotor.
Background technology
The degree of registration at generator stator-rotator magnetic power center is to rely on the manufacturing accuracy of support stator core, rotating shaft rotor core to guarantee magnetic force center degree.The center of support stator core is press fit into by support machining precision, stator core machining precision and stator core that precision in the support and rotating shaft machining precision determine, and that iron core is pressed into the precision of support is generally lower, especially for the sliding bearing generator, owing to when the magnetic force center degree of stator core and rotating shaft rotor core is bad, cause that easily the bearing temperature temperature raises.Alternator shaft can produce an electromagnetic axial power when the magnetic force center-aligned degree of electricity generator stator core and rotor core is bad, cause machine shaft bearing axial rub to increase, cause the sliding bearing temperature to raise, the on-the-spot degree of registration testing tool of being badly in need of a kind of electric machine rotor magnetic force center.
Summary of the invention
The utility model provides a kind of electric machine rotor magnetic force center-aligned detection ruler, has solved on-the-spot technical matters of simply and easily the degree of registration at electric machine rotor magnetic force center not being carried out testing tool.
The utility model overcomes the above problems by following scheme:
A kind of electric machine rotor magnetic force center-aligned detection ruler, comprise the strip substrate, the strip substrate is provided with the length rule, the measuring point of length rule is provided with measures the jig plush copper, and the height of measuring the jig plush copper is 1.5 times of the gas length that forms between motor stator and the rotor.
Head at the strip substrate is semicircle.
The utility model reduced the problem that bearing temperature that the bearing end friction that causes because of axial electromagnetic force in the motor test causes raises and transfinites, reduced motor bearings and disassembled the number of times of adjusting and repairing watt, reduced the time that motor covers testing table.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A direction view among Fig. 1.
Embodiment
A kind of electric machine rotor magnetic force center-aligned detection ruler, comprise strip substrate 3, strip substrate 3 is provided with length rule 4, the measuring point of length rule 4 is provided with measures jig plush copper 2, and the height H of measuring jig plush copper 2 is 1.5 times of the gas length that forms between motor stator and the rotor.
Head 1 at strip substrate 3) be semicircle.
If motor stator core and rotor core are isometric, distance with nose circle face and rotor core cylindrical tip-to-face distance electric machine stand end face seam machined surface in the utility model measurement stator core, institute is surveyed two numerical value subtract each other, its difference is the degree of registration at stator-rotor iron core magnetic force center.In order to guarantee that ruler does not damage the machine winding coil insulated hull when measuring, strip substrate 3 usefulness epoxy phenolic laminated glass fabric plates make, the measuring point of length rule 4 is provided with measures jig plush copper 2, and the height H of measuring jig plush copper 2 is 1.5 times of the gas length that forms between motor stator and the rotor.The head of strip substrate 3 is repaiied and is rasped to the round end shape and certain gradient is arranged, and each corner angle is polished into circular arc, smooth surface, the measuring head width is less than blade, be about chi wide 1/2nd, each corner angle of side head also polish smooth, in order to avoid winding coil insulation skin is caused damage.
Claims (2)
1. electric machine rotor magnetic force center-aligned detection ruler, comprise strip substrate (3), strip substrate (3) is provided with length rule (4), it is characterized in that, the measuring point of length rule (4) is provided with measures jig plush copper (2), and the height (H) of measuring jig plush copper (2) is 1.5 times of the gas length that forms between motor stator and the rotor.
