Abstract
The utility model discloses a motor heat dissipation impeller which is an improved novel motor heat dissipation impeller. The novel motor heat dissipation impeller comprises a hub and a plurality of blades evenly arranged on the periphery of the hub. The novel motor heat dissipation impeller is characterized in that a groove used for storing a gasket is formed in the right end of the hub, the groove can effectively prevent the gasket from generating noise caused by high-temperature deformation and can prevent the gasket from causing motor failures due to the fact that the gasket is thrown away due to centrifugal force, and the novel motor heat dissipation impeller has the advantages of being simple in structure, low in cost, firm and durable, and is mainly used for motor heat dissipation.
Description
Technical field
The utility model relates to a kind of Heat-dissipating impeller of motor, relates in particular to a kind of New-type electric machine heat-dissipating impeller.
Background technique
Present Heat-dissipating impeller of motor; when being installed to motor shaft; for vibrations and minimizing impeller and the tightening nut direct friction that reduces impeller; usually can pad be installed at the impeller right-hand member, this pad uses this class of rubber to have certain flexible material usually, because motor can produce high temperature when high speed rotating; the easy deliquescing and being out of shape when being subject to high temperature of this rubber material; in the situation of high rotating speed high centrifugal force, just distortion gets loose easily, causes easily electrical fault like this.
The model utility content
The purpose of this utility model technical problem to be solved is that a kind of New-type electric machine heat-dissipating impeller will be provided, and it can efficiently solve pad and be subject to high temperature and be out of shape the problem that forms electrical fault, has characteristics simple in structure, with low cost, robust.
For achieving the above object, the technical solution adopted in the utility model is: a kind of New-type electric machine heat-dissipating impeller, comprise wheel hub and some blades that evenly is provided with on its excircle, it is characterized in that: the right-hand member of described wheel hub is provided with a groove that is used for placing pad; Described blade and described wheel hub are orthogonal; The quantity of described blade is eight; Be provided with the through hole for the suit motor shaft in the middle of the described wheel hub, the internal diameter of this through hole is greater than the external diameter of described motor shaft; Also be provided with the support ring for increasing described wheel hub and described blade junction surface on the described wheel hub; The external diameter of described wheel hub left end is less than the external diameter of right-hand member.
The utility model has adopted above-mentioned technological scheme, overcome the deficiency of background technique, a kind of New-type electric machine heat-dissipating impeller is provided, and it can efficiently solve pad and be subject to high temperature and be out of shape the problem that forms electrical fault, has characteristics simple in structure, with low cost, robust.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is left view of the present utility model.
Among the figure: wheel hub 1, blade 2, groove 11, support ring 12, through hole 13.
Embodiment
Below in conjunction with accompanying drawing, by embodiment of the present utility model is further described, make the technical solution of the utility model and beneficial effect thereof clearer, clear and definite.
Referring to accompanying drawing 1 to 2, the utility model comprises wheel hub 1 and some blades 2 that evenly is provided with on its excircle, it is characterized in that: the right-hand member of described wheel hub 1 is provided with a groove 11 that is used for placing pad; Described blade 2 and described wheel hub 1 are orthogonal; The quantity of described blade 2 is eight; Be provided with the through hole 13 for the suit motor shaft in the middle of the described wheel hub 1, the internal diameter of this through hole 13 is greater than the external diameter of described motor shaft; Also be provided with on the described wheel hub 1 for increasing the support ring 12 of described wheel hub 1 with described blade 2 junction surfaces; The external diameter of described wheel hub 1 left end is less than the external diameter of right-hand member.
Impeller is installed on the motor shaft, size and the pad of groove 11 match, pad is installed in the groove 11, then fix with nut, motor can produce high temperature when high speed rotating, this high temperature is passed to pad by motor shaft, because pad is installed in the groove 11, even the Yin Gaowen high centrifugal force can both keep shape invariance.
Description by above-mentioned structure and principle; the person of ordinary skill in the field is to be understood that; the utility model is not limited to above-mentioned embodiment; adopt the improvement of techniques well known on the utility model basis and substitute and all drop on protection domain of the present utility model, should be limited by each claim.
