Abstract
The utility model discloses a fan casing for a motor. A ventilation window is formed at the outside end of the fan casing, a plurality of bosses are formed at the inside end of the fan casing, namely the inner wall of the end which is connected with a cylinder body, and a tightening hole is formed in the center of each boss. The relative positions of the fan casing and the cylinder body of a casing are improved, and ventilation gaps are formed between the inner wall of the fan casing and the outer wall of the cylinder body by using the support of the bosses, so that the blowing effect of a fan can obviously influence the flowing of air around the outer peripheral wall of the cylinder body of the casing, and a heat radiating effect can be obviously improved.
Description
Technical field
The utility model belongs to the motor configuration design field, is specifically related to a kind of fan guard that is used for motor.
Background technique
The puzzlement of maximum during motor uses is no more than heat dissipation problem.If motor can't dispel the heat quickly and effectively, then can run off and cause lubricant oil because of rolling bearing can't bear motor high temperature, cause rotation system to lose efficacy, cause motor to burn.
Traditional type motor casing, outer surface are provided with several guiding gutters, and the shape of cross section of each groove generally is rectangle, U font etc., but its radiating effect is often unsatisfactory, remains needing improvements badly.And concerning some miniature motors,, guiding gutter is set not on its barrel outer surface in order to reduce overall volume.
Mostly traditional improvement radiating mode is that fan blowing effect carries out through changing, but because fan guard closely is located on the motor cylindrical shell, the blowing effect of fan is very little to the influence of the air flow on the motor cylindrical shell outer surface.
Have at present the auxiliary heat dissipation sheet to be set to increase radiating effect on the motor casing outer surface, still this structure need take than large space, and obviously increases many materials, and cost is higher.
The model utility content
The purpose of the utility model provides a kind of fan guard that is used for motor that can obviously improve radiating effect.
The technological scheme that realizes the utility model purpose is: a kind of fan guard that is used for motor; The outboard end of said fan guard is provided with transom; It is characterized in that: the medial extremity of said fan guard also promptly links to each other with cylindrical shell on the inwall of an end, is provided with several boss, and each boss center is provided with fastener hole.
Said boss exceeds the distance of fan guard inwall more than or equal to 1mm, is preferably greater than to equal 3mm and smaller or equal to 20mm.
The utlity model has positive effect: (1) the utility model is through improving the relative position between fan guard and the casing cylindrical shell; Utilize the support of boss to make and leave ventilation gap between inwall and the cylinder body outer wall of fan guard; Thereby make the blowing effect of fan can obviously have influence on flowing of casing cylindrical shell periphery wall air, can obviously improve radiating effect.

Embodiment
(embodiment 1)
Fig. 1 to Fig. 2 has shown a kind of embodiment of the utility model, and wherein Fig. 1 is a kind of perspective view of the utility model; Fig. 2 is a kind of sectional view of fan guard shown in Figure 1.
Present embodiment is a kind of fan guard that is used for motor; See Fig. 1 to shown in Figure 2, the outboard end of said fan guard 2 is provided with transom 21, and the medial extremity of said fan guard 2 also promptly links to each other with cylindrical shell 12 on the inwall of an end; Be provided with several boss 3, each boss 3 center is provided with fastener hole 31.
In concrete practice, said boss 3 exceeds the distance of fan guard 2 inwalls more than or equal to 1mm, is preferably greater than to equal 3mm, equals 20mm but generally be less than.
Present embodiment is through improving the relative position between fan guard and the casing cylindrical shell; Utilize the support of boss to make and leave ventilation gap between inwall and the cylinder body outer wall of fan guard; Thereby make the blowing effect of fan can obviously have influence on flowing of casing cylindrical shell periphery wall air, can obviously improve radiating effect.
(application examples 1)
Fig. 3 and Fig. 4 have shown a kind of concrete application mode of the utility model, and wherein Fig. 3 is a kind of application schematic representation of fan guard shown in Figure 1; Fig. 4 is a kind of sectional view of motor shown in Figure 3.
Should use-case be a kind of motor that adopts the foregoing description 1 to process, see Fig. 3 and Fig. 4, comprise motor case 1 and be arranged on the fan guard 2 on the casing 1; Said casing 1 comprises tail-hood 11 and the cylindrical shell 12 that fuses with tail-hood 11; Said fan guard 2 is arranged on the end that casing 1 is provided with tail-hood 11, and is set on cylindrical shell 12 periphery walls; Said fan guard 2 links to each other with cylindrical shell 12 on the inwall of an end, is provided with several boss 3, and each boss 3 center is provided with fastener hole 31, and said fan guard 2 is provided with transom 21 away from an end of tail-hood 11; Said cylindrical shell 12 is provided with several screws 13 that matches with said boss 3; Under the supporting effect of each boss 3, said fan guard 2 links to each other with cylindrical shell 12 and leaves ventilation gap between inwall and this place's cylindrical shell 12 periphery walls of an end.
Should pass through to improve the relative position between fan guard and the casing cylindrical shell by use-case, thereby make the blowing effect of fan can obviously have influence on flowing of casing cylindrical shell periphery wall air, can obviously improve radiating effect.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection domain of the utility model.
