Abstract
The utility model discloses a pressing ring structure used for a brushless excitation motor rotor. The pressing ring structure uses a support pressing ring structure and comprises a pulling plate and three circular rings. The three circular rings are fixed on the top, the middle, and the bottom of the pulling plate, respectively. Therefore, a support using the pulling plate as a supporting main body is formed. The inner diameter of the circular ring at the middle of the pulling plate and the inner diameter of the circular ring at the bottom of the pulling plate are more than or equal to the external diameter of a motor rotor core. Therefore, the motor rotor core can be sleeved in the middle circular ring and the bottom circular ring. The circular ring on the top of the pulling plate is used for supporting a coil wound on the rotor core. The pressing ring structure has characteristics of a simple and reliable structure, easy assembly, and low cost.

Technical field
The utility model relates to the mounting technology of brushless exciting motor rotor, is specifically related to a kind of brushless exciting motor rotor ring pressing construction, is used for the pressing process process of excitation electromotor rotor core.
Background technology
In brushless excitation synchronous generator, the general volume of exciter rotor is smaller, and structure is compact, there is no at present unified regulation and requirement for the compression of its iron core and the colligation of end.The compression Adopts measure of iron core mainly contains bonding end plate, trim ring or stretching screw.The present use of colligation of end be to adopt a glass steel loop more widely, with the overhang colligation on the glass steel loop.There are the exciter rotor in axial ventilation road often, simultaneously in, groove number higher for some rotating ratios and number of poles, and there is certain difficulty in the installation of the line of end winding and colligation and balance weight.
The utility model content
The purpose of this utility model is to provide a kind of brushless exciting motor rotor ring pressing construction, effectively compresses iron core, facilitates coil to facilitate end winding line and colligation, solves simultaneously the installation question of balance weight.
The technical scheme that the utility model technical solution problem adopts is: a kind of brushless exciting motor rotor ring pressing construction, adopt the stent-type ring pressing construction, comprise arm-tie and three annulus, three annulus are separately fixed at top, middle part and the bottom of described arm-tie, form the support take arm-tie as supportive body, the internal diameter of described arm-tie middle part, bottom annulus is slightly larger than or equals the external diameter of motor rotor core, make motor rotor core can be inserted in the middle part, in the annulus of bottom, described arm-tie top annulus is used for the coil that is wound around on the support rotor iron core.
Further, have hole on described arm-tie, be used for installing balance weight.
Further, the internal diameter of described bottom annulus preferentially compresses the iron core excircle part than the large 0.5 ~ 1mm of internal diameter of middle part annulus when making rotor core in putting this ring pressing construction into.
Further, described arm-tie top annulus is provided with the dark groove of 2mm ~ 3mm, and after rotor coil bandaged insulator, insulator was placed in the groove of arm-tie top annulus, prevents from moving left and right.
The utility model has the advantage of: 1) by arrange take arm-tie as main body, annulus is the support of support component, makes rotor core reliably be compressed; 2) arm-tie is provided with hole for balance weight is installed, and makes the balance weight installation question obtain good solution; 3) the poor design in arm-tie middle part, bottom internal radius and the design of top ring groove, make rotor core place in this ring pressing construction steadily, for follow-up work provides reliable basis.The utility model overall structure is simple and reliable, and is easy to assembly, with low cost.
