Abstract
The utility model discloses a rotor component of a traction motor, which comprises an armature shaft, a commutator, an iron core and a rotor coil set. The armature shaft is arranged at the axial center at the right end of the rotor component, the commutator is arranged on the armature shaft, the iron core comprises a silicon steel sheet, and the rotor coil set is wound on the iron core. An armature shaft driving device is arranged at the axial center at the left end of the rotor component, and the rotor coil set is formed by winding a flat enameled wire. The rotor component of a traction motor has the advantages that the coil set of the rotor component is formed by winding the flat enameled wire, so that the structure of the coil set is more compact relatively to the structure of a coil set formed by winding a circular enameled wire, the coil set formed by winding the flat enameled wire is smaller in volume compared with a coil set with the same cycles, the sectional area of the flat copper enameled wire is large, and the rotor component has stronger mechanical strength and rigidity and higher bearing capacity.
Description
Technical field
The utility model relates to the rotor assembly of a kind of rotor of motor, particularly a kind of traction electric machine.
Background technology
The operation principle of traction motor is identical with general DC motor, but special condition of work is arranged, bulk is subjected to the restriction of gauge and driving wheel diameter, when closing track switch by rail gap, locomotive operation to bear sizable impact shock, can produce strong twisting vibration on the armature during size poor gear engagement, in adverse circumstances, use rain, the easy intrusion of snow dust and sand etc.Therefore traction motor also has many requirements on design and structure, make compact conformation as making full use of the internal body space, adopt higher insulating material and arrive this material, parts need have higher mechanical strength and rigidity, whole motor must have good ventilation and heat condition and dust and moisture ability, take special measure with the commutation condition of dealing with the comparison difficulty to reduce spark under the carbon brush etc.At present, the coil groups of the rotor assembly of existing traction electric machine all is to form with round copper enamelled wire coiling, can leave a lot of slits in the middle of the coil groups, and the volume of coil groups is increased, and does not satisfy the designing requirement of traction locomotive electric machine structure compactness.
Summary of the invention
The purpose of this utility model is at the bulky problem of the coil groups of the rotor assembly of the existing traction electric machine described in the background technology, and a kind of carriage traction electric machine rotor assembly is provided.
The realization the technical solution of the utility model is as follows:
A kind of rotor assembly of traction electric machine, it comprise the axial centre that is arranged at the rotor assembly right-hand member armature shaft, be arranged at commutator on the armature shaft, the iron core formed by silicon steel sheet, be wrapped in the rotor coil group on the iron core, the axial centre of described rotor assembly left end is provided with the armature shaft drive unit, and described rotor coil group is entwined with flat enamelled wire.
Described armature shaft drive unit is a spline housing.
Be provided with groove in the described rotor coil group and sign and insulating paper, in order to make rotor coil group structure tightr, rotor coil group arranged outside has or not the latitude band.
The beneficial effects of the utility model are that the coil groups of the rotor assembly of traction electric machine forms with the coiling of flat copper enamelled wire, so it is tightr with respect to the coil groups structure that round copper enamelled wire coiling forms, coil groups for same number of turns, the coil groups volume that turns to flat type copper wire is littler, and flat copper enamelled wire sectional area is big, its mechanical strength and rigidity are stronger, and bearing capacity is higher.Because rotor assembly adopts the drive unit of spline housing 5 as armature shaft, it is stressed more even with being connected of armature shaft, can bear bigger load, and guidance quality is good, the centering precision height, and transmitting torque is big.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Among the figure, 1 is rotor core, and 2 is the rotor coil group, and 3 is armature shaft, and 4 is commutator, and 5 is spline housing, and 6 are no latitude band, and 7 are the groove label, and 8 is insulating paper.
Embodiment
Rotor assembly with reference to a kind of traction electric machine shown in the accompanying drawing 1, it comprise the axial centre that is arranged at the rotor assembly right-hand member armature shaft 3, be arranged at commutator 4 on the armature shaft 3, the iron core 1 formed by silicon steel sheet, be wrapped in the rotor coil group 2 on the iron core, the axial centre of described rotor assembly left end is provided with the armature shaft drive unit, and the flat enamelled wire of described rotor coil group 2 usefulness is entwined.Described armature shaft drive unit is a spline housing 5.Be provided with groove label 7 and insulating paper 8 in the described rotor coil group 2, in order to make rotor coil group structure tightr, rotor coil group arranged outside has or not latitude band 6.At present, the rotor coil group 2 of the rotor assembly of existing traction electric machine all is to form with round copper enamelled wire coiling, because it is bigger that circular copper wire and flat copper enamelled wire are compared the space that produces in the winding process, so coil groups of the same number of turns, volume with the coiling of flat copper enamelled wire is littler, more satisfy the application demand of traction electric machine, be more suitable for being applied to traction electric machine.Because rotor assembly adopts the drive unit of spline housing 5 as armature shaft 3, it is stressed more even with being connected of armature shaft 3, can bear bigger load, and guidance quality is good, the centering precision height, and transmitting torque is big.Because need certain force of strain when not having 6 colligations of latitude band, tension force comes colligation greatly about 40-80kg by machine, can make rotor coil group structure tightr.
