Изобретение относитс к области электротехнических машин, в частности к роторам внополюсных машин.The invention relates to the field of electrical machines, in particular to rotors of pole-mounted machines.

Известны роторы внополюсных электрических машин l , содержащие полюсные наконечники, установленные с помощью шпонок.Known rotors vopolopolisnyh electrical machines l, containing pole pieces installed with dowels.

Недостатком такой конструкции вл етс значительна толщина ступицы, что увеличивает вес и габариты ротора .The disadvantage of this design is the considerable thickness of the hub, which increases the weight and dimensions of the rotor.

Известны также роторы внополюсных электрических машин 2 , содержащие ступицу крестообразной формы, на выступах которой установлены полюсные наконечники, укрепленные осегвыми шпонками, установленными в зубцах и пазах наконечника и выступа.Also known are rotors of electropolar electric machines 2 containing a cruciform hub, on the protrusions of which there are pole pieces, fortified with axle pins mounted in the teeth and grooves of the tip and protrusion.

Данное техническое решение наи более близко изобретению по технической сущности и достигаемому эффекту .This technical solution is the closest to the invention according to its technical essence and the effect achieved.

Недостатком этой конструкции вл етс ее мала надежность из-за консольного расположени полюсных наконечников и невозможность замены катушки при ремонте, поскольку ротор выполнен неразъемным.The disadvantage of this design is its low reliability due to the cantilever arrangement of pole pieces and the impossibility of replacing the coil during repairs, since the rotor is made integral.

Целью изобретени вл етс повышение надежности и ремонтоспособности ротора.The aim of the invention is to increase the reliability and maintainability of the rotor.

Цель достигаетс тем, что в предлагаемой . машине на выступах ступицы выполнены зубцы, размещенные в пазах полюсных наконечников. . , На чертеже представлена часть поперечного сечени ротора.The goal is achieved in that in the proposed. The machine has teeth on the projections of the hub, which are located in the grooves of the pole pieces. . The drawing shows a portion of the rotor cross section.

Claims

The rotor contains a shaft 1, on which the hub 2 is installed with protrusions 3, teeth 4 are made on protrusions 3 and pole pieces 5 are installed with grooves 6 in which teeth 4 are placed. ) c. 7, The excitation coils 8 are mounted on the protrusions of step 2. Since the pole piece is made entirely from one pole, its strength and reliability increase. In addition, the pole piece can be removed from the hub during repair of the field coils, which simplifies the repair of the rotor. Placing the hub teeth in the grooves of the pole tip reduces the size and weight of the rotor, since the protrusions of the pole tips can be 8.6 located directly on the coils without spacers. Claims of the invention A rotor of a pole-mounted electric machine containing a cruciform hub, on the protrusions of which are mounted pole pieces, fortified with axial keys mounted in the teeth and grooves of the tip and protrusion, are distinguished by the fact that, placed in the grooves of pole pieces.
