Description
Technical field
The utility model relates to a kind of motor component structure, especially a kind of modular rotor structure of magneto.
Background technology
At present, existing rotor structure for permanent magnet motor in length, because the motor of different capacity grade, different rotating speeds or different moment of torsion is different.And in actual application, require motor and user's joint constant, and power, moment of torsion, speed are different.Namely rotor punching is constant, by changing rotor length, realizes different requirements.
Summary of the invention
The technical problems to be solved in the utility model is existing permanent magnet machine rotor poor real, can not need to regulate according to practical application.
In order to solve the problems of the technologies described above, the utility model provides a kind of modular rotor structure of magneto, comprises armature spindle, positive stop key, at least two rotor units, spacer ring, left retainer ring, right retainer ring and shaft block rings; Positive stop key is embedded on armature spindle along the axis of armature spindle; Left retainer ring is fixed on the left end of armature spindle, and rotor unit is set in armature spindle from the right-hand member of armature spindle, and right retainer ring overlaps from the right-hand member of armature spindle and fixed by shaft block ring; Rotor unit is held between the solid ring of left retainer ring and the right side, and spacer ring is between adjacent two rotor units; The outer circumferential edges of left retainer ring and right retainer ring is equipped with the flange of outer folding; Flange inwall is provided with counterweight clay.
Adopt positive stop key, left retainer ring, right retainer ring and spacer ring to carry out splicing to multiple rotor unit to fix, enable the performance parameter of the length of rotor required for practical application carry out free assembling, thus effectively improve the universality of this rotor structure; Adopt positive stop key can pass on armature spindle by the moment of torsion of rotor unit, reach the output of moment of torsion; Adopt and left retainer ring and right retainer ring are set respectively at armature spindle two ends, can either be used for playing balanced action, can be fixed rotor unit again; Adopt counterweight clay, two ends, the left and right relative equilibrium of armature spindle can be realized, improve the stability of rotor turns; Adopt flange that counterweight clay can be prevented to be thrown out of under the influence of centrifugal force.
As further restriction scheme of the present utility model, rotor unit is by silicon steel sheet and be fixed on silicon steel sheet magnet steel circumferentially and form.Adopt rotor unit can ease of assembly, meet application demand fast.
The beneficial effects of the utility model are: (1) adopts positive stop key, left retainer ring, right retainer ring and spacer ring to carry out splicing to multiple rotor unit and fixes, enable the performance parameter of the length of rotor required for practical application carry out free assembling, thus effectively improve the universality of this rotor structure; (2) adopt positive stop key can pass on armature spindle by the moment of torsion of rotor unit, reach the output of moment of torsion; (3) employing arranges left retainer ring and right retainer ring respectively at armature spindle two ends, can either be used for playing balanced action, can be fixed again to rotor unit; (4) adopt counterweight clay, two ends, the left and right relative equilibrium of armature spindle can be realized, improve the stability of rotor turns; Adopt flange that counterweight clay can be prevented to be thrown out of under the influence of centrifugal force.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the modular rotor structure of magneto of the present utility model comprises: comprise armature spindle 1, positive stop key 2, at least two rotor units 3, spacer ring 4, left retainer ring 5, right retainer ring 6 and shaft block rings 9.Wherein, positive stop key 2 is embedded on armature spindle 1 along the axis of armature spindle 1; Left retainer ring 5 is fixed on the left end of armature spindle 1, and rotor unit 3 is set in armature spindle 1 from the right-hand member of armature spindle 1, and right retainer ring 6 overlaps from the right-hand member of armature spindle 1 and fixed by shaft block ring 9; Rotor unit 3 is held between the solid ring 6 of left retainer ring 5 and the right side, and spacer ring 4 is between adjacent two rotor units 3; The outer circumferential edges of left retainer ring 5 and right retainer ring 6 is equipped with the flange 8 of outer folding; Flange 8 inwall is provided with counterweight clay 7; Rotor unit 3 is by silicon steel sheet and be fixed on silicon steel sheet magnet steel circumferentially and form.
From the principle, have a gimbal respectively at the two ends of rotor, be used for dynamic balancing time, paste balance clay.Gimbal sweep prevents balance clay from throwing away under the influence of centrifugal force.Left-right balance ring has been held concurrently end plate effect, prevents rotor unit axial play; Rotor unit is set on armature spindle, and spacer ring is between adjacent two rotor units; Rotor punching inner periphery is the pawl divided equally, and has both alleviated punching weight, and can realize connecting without key, and increases the magnitude of interference when connecting with interference, and hot jacket success rate is high, transmitting torque reliable action.Adopt positive stop key, left gimbal, right gimbal and spacer ring to carry out splicing to multiple rotor unit to fix, enable the performance parameter of the length of rotor required for practical application carry out free assembling, thus effectively improve the universality of this rotor structure; Adopt dividing plate can make to remain with uniform intervals between adjacent two rotor units, make the rotor structure after assembling keep compact.Rotor unit is by silicon steel sheet and be fixed on silicon steel sheet magnet steel circumferentially and form.Adopt rotor unit can ease of assembly, meet application demand fast.
The modular rotor structure of magneto of the present utility model is when practical application, first according to demand, after electromagnetism and mechanical calculations, the rotor unit 3 of suitable number is assembled on armature spindle 1, and undertaken spacing by left retainer ring 5 and right retainer ring 6 pairs of two ends, finally carry out axial location with packing ring and shaft block ring 9 again.Rotor unit 3 can locate transmitting torque with positive stop key 2, and interference fit also can be adopted to carry out transmitting torque, thus the intensity losses that the fluting reducing armature spindle 1 brings.All rotor units 3 share a stator, achieve center height identical; By regulating the length of rotor, realize connected mode identical, and the electric machine structure that power grade, rotating speed and moment of torsion are different.Decrease complicated electromagnetism to calculate and drawing protract, facilitate store management and storage.
