Abstract

The utility model relates to a motor part, aiming to provide a motor rotor framework so as to solve the problem of poor heat radiating performance of a rotor in the prior art. The purpose of the utility model can be achieved by means of the measures as follows: the motor rotor framework in the utility model comprises a bottom plate, a central hole is formed in the center of the bottom plate, a clapboard is arranged at the side of the central hole, a wire blocking column is arranged in the middle of the bottom plate, and wire blocking slots are arranged at two sides of the bottom plate; and the motor rotor framework is characterized in that a strip-shaped empty slot is formed in the bottom plate, on a face through which a coil passes. Compared with the prior art, the technical scheme disclosed by the utility model has the characteristics that the strip-shaped empty slot is formed in the bottom plate, on the face through which the coil passes; the strip-shaped empty slot can be formed by digging the bottom plate; and after a rotor coil is mounted completely, an iron core fixed among the framework is not tightly appressed to the coil wound on the framework any longer, the strip-shaped empty slot plays a certain role in buffering, and air can flow in the strip-shaped empty slot and takes away heat so as to prevent the accumulated heat of the iron core and the coil from influencing the service life of a rotor.

Description

The rotor skeleton

Technical field

The utility model relates to a kind of parts of motor.

Background technology

Generator is through the rotation of rotor in stator, makes cutting magnetic line movement, produces induced electromotive force, produces electric current through closed load circuit again.The rotor of generator mainly is made up of rotor core, rotor skeleton, rotor line bag and line bag pressing plate etc., wherein, is equipped with rotating shaft in the middle of the rotor core; On rotor core, be provided with line embedding groove longitudinally, the rotor skeleton passes the axle journal at rotor core two ends, is installed on the rotor core; Equally; Also be provided with line embedding groove on the rotor skeleton, the rotor line surrounds in the line embedding groove of rotor skeleton and rotor core, and through screw and line bag pressing plate rotor line bag and rotor core is fixed.

Being widely used of motor, different occasions needs different motor of all kinds, and corresponding, the rotor skeleton of shape features also becomes the focus that motor manufacturer designs and develops.

The utility model content

The utility model is intended to provide a kind of rotor skeleton that possesses new structure, to cooperate the machine operation of respective specific structure.

The purpose of the utility model can reach through following measure: the rotor skeleton in this programme, comprise base plate, and the base plate center is provided with the centre bore that round wall surrounds; The base plate both sides are provided with the retaining wire casing, it is characterized in that: the both sides of said round wall are provided with dividing plate, and said retaining wire casing is " M " shape; Be symmetrically arranged with two wire-blocking boards on the base plate; The lower edge, two ends of wire-blocking board is connected with the left and right sides outer edge of retaining wire casing " M " shape, and said wire-blocking board height is 32.75mm, and the wire-blocking board outside is provided with brace rod; The height of said round wall is 32.75mm, and the inwall radius is 14.5mm.

The size of its qualification is used for matching with the electric machine structure of certain fixed dimension, and described height is for the base plate lower plane.

Further: described rotor skeleton is processed by the nylon material that contains glass fiber.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:

Fig. 1 is the sketch map of the utility model embodiment;

Fig. 2 looks sketch map for the master of the utility model embodiment;

Fig. 3 is that the A-A of Fig. 2 is to cross-sectional schematic.

Embodiment

Known concrete structure and characteristic are no longer set forth at this in the following proposal.As shown in Figure 1: whole base plate 1 is symmetric design according to the centre bore 2 at middle part, is processed by the nylon that is added with 15% glass fiber six.

Quilt circle wall 3 surrounds around the centre bore 2, and it is that the one observation is " M " shape that the base plate both sides are provided with four retaining wire casings, 4, two retaining wire casings altogether; The retaining wire casing 4 other wire-blocking boards 5 that are provided with of homonymy; Two wire-blocking boards 5 are according to the axial symmetry setting of centre bore 2, and the lower edge, two ends of wire-blocking board is connected with the left and right sides outer edge of retaining wire casing " M " shape, and the outside of wire-blocking board 5 is provided with brace rod 6; The base plate in wire-blocking board 5 outsides is provided with the square breach 7 that is intended to economical with materials, and the both sides of circle wall 3 are provided with dividing plate 8.

Like Fig. 2, Fig. 3, shown in Figure 4: the thickness 101 of base plate 1 is 2mm, and the distance 102 of distance center hole, the edge axle of base plate 1 is 53.57mm.

The wall high 301 of the round wall 3 around the centre bore 2 is 32.75mm, and the wall thickness 302 of circle wall 3 is 1.3mm, and circle wall 3 inwall radiuses 303 are 14.5mm.

The height 501 of wire-blocking board 5 is 32.75mm, and the wall thickness 502 of wire-blocking board 5 is 1.3mm, and the distance 503 of wire-blocking board 5 span centre hole axis in the inner part is 33.3mm, and wire-blocking board 5 outside brace rods 6 are 120 ° with the angle 601 of backplate surface.

Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection range of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
