Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of heat radiation rotor punching.
Background technology
The vent hole structure of the energy index of threephase asynchronous and its rotor punching has very large contact, and different aeration structures has different performances, and the especially temperature rise of motor, efficiency index relate to efficiency examination.The structure of existing rotor punching single circle distribution round vent is a kind of traditional design, mainly consider from avoiding affecting rotor strength, but heat radiation is not very desirable, and cause the temperature rise of motor in a lot of situation too high, efficiency is undesirable.Simultaneously along with the continuous increase of motor frame number, power and rotating speed, original design design concept or reliability all can not meet design requirement.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind ofly to strengthen the heat radiation rotor punching that integral heat sink performance also ensures rotor strength simultaneously.
The purpose of this utility model realizes by following technical proposal: a kind of heat radiation rotor punching, comprise body, body central place is provided with axis hole, body peripheral is laid with wire casing, it is characterized in that: be provided with between described wire casing and axis hole and somely take axis hole as axle annular spread and for a plurality of ventilation hole one and a plurality of ventilation hole two, and ventilation hole one and ventilation hole two interval are arranged, dowel one and dowel two is formed between described ventilation hole one and adjacent two ventilation holes two, described dowel one and dowel two are to be symmetricly set on ventilation hole one both sides through the plane of symmetry of axis hole axis, dowel one and dowel two have identical acute angle with the described plane of symmetry respectively, and dowel one and dowel two extend intersecting lens with axis hole axis being parallel does not overlap.
Owing to having spaced ventilation hole one and ventilation hole two, integral heat sink performance is got a promotion, again owing to forming dowel one and dowel two between ventilation hole one and adjacent two ventilation holes two, and dowel one and dowel two extend intersecting lens with axis hole axis being parallel does not overlap, therefore dowel one and dowel two are certain angle and are obliquely installed, even if make, behind stronger ventilation hole one and ventilation hole two area, can also ensure that there is good intensity.
As preferably, described ventilation hole one is for having the sector structure on inner arc limit and outer arc limit, ventilation hole one inner arc limit is arranged closer to axis hole than outer arc limit, ventilation hole two is isosceles triangular structure, the base of ventilation hole two correspondence arranges towards axis hole and is arc, and the base of ventilation hole two and axis hole are coaxially arranged.
Therefore the area of ventilation hole one can be increased, improving radiating effect.
As preferably, described ventilation hole one and ventilation hole two are isosceles triangular structure, and the drift angle of ventilation hole one correspondence is arranged towards axis hole, the reverse axis hole of drift angle of ventilation hole two correspondence is arranged, and the base of described ventilation hole one correspondence and the base of ventilation hole two correspondence are arc, and coaxially arrange with axis hole.
Therefore integral heat sink is more even.
As preferably, ventilation hole one and ventilation hole two angle are fillet.
As preferably, described body is silicon steel or silicon steel, and surface uniform graphite spraying antirust paint.
Compared with prior art, the utility model tool has the following advantages:
Owing to having spaced ventilation hole one and ventilation hole two, integral heat sink performance is got a promotion, again owing to forming dowel one and dowel two between ventilation hole one and adjacent two ventilation holes two, and dowel one and dowel two extend intersecting lens with axis hole axis being parallel does not overlap, therefore dowel one and dowel two are certain angle and are obliquely installed, even if make, behind stronger ventilation hole one and ventilation hole two area, can also ensure that there is good intensity.
