Abstract
The utility model discloses a motor tensile end cover, including an end cover body. A cavity is formed in the middle of the end cover body. A bottom portion of the end cover body is provided with an opening. A top portion of the end cover body is provided with an end panel. The middle of the end panel is recessed downward and forms a groove. A bottom plate is formed in a bottom portion of the groove. The middle of the bottom plate protrudes upward out of a bearing seat. A plurality of heat radiation holes are provided on an outer side of the bottom plate and a side wall of the groove. The motor tensile end cover has a simple structure, increases the heat radiation opening area, and is fast in heat radiation and good in heat radiation effect.
Description
Technical field:
The utility model relates to a kind of motor stretching end cover.
Background technology:
Because the motor market competition is more and more fierce, motor cost is controlled more and more lower, problem of temperature rise is highlighted, and traditional electric motor end cap, be illustrated in fig. 1 shown below, comprise end cap body 1, the annular bottom plate 13 of end cap body 1 is provided with some arc-shaped through-holes 134, there is following technological deficiency in this end cover structure: 1) the end cap perforated area is large not, causes the discharging of motor heat undesirable; 2) since on the motor performance designing requirement rotor with cooling wind blade, the cooling wind blade radius of gyration is usually less than annular bottom plate, the air of motor institute distribute heat can not flow out rapidly with beeline, unfavorable to reducing electric machine temperature rise, radiating effect is poor.
Summary of the invention:
The purpose of this utility model is for the technological deficiency that exists in the prior art, and a kind of motor stretching end cover is provided, and this is simple in structure, has increased the heat radiation perforated area, rapid heat dissipation, good heat dissipation effect.
The purpose of this utility model is to be achieved by following technical scheme.
A kind of motor stretching end cover, comprise the end cap body, form cavity in the middle of the end cap body, the bottom of end cap body is provided with opening, the top arranges end plates, is recessed to form groove in the middle of the end plates downwards, forms base plate at bottom portion of groove, bearing pedestal protruding upward in the middle of the base plate is provided with some louvres at the sidewall of plate outer side, groove.
Described above is provided with some arc-shaped through-holes at the groove outside, end plates.
Be provided with the reinforcement boss between adjacent two arc-shaped through-holes described above, strengthen boss and extend to sidewall.
Some louvres described above are 16, are divided into 4 groups and are distributed on the sidewall.
Some arc-shaped through-holes described above are 4, are distributed on the base plate.
End cap body described above is hat-shaped.
The beneficial effects of the utility model are: 1) the utility model comprises the end cap body, form cavity in the middle of the end cap body, the bottom of end cap body is provided with opening, and the top arranges end plates, be recessed to form groove in the middle of the end plates downwards, form base plate at bottom portion of groove, bearing pedestal protruding upward in the middle of the base plate is provided with some louvres at the sidewall of plate outer side, groove, simple in structure, increased the heat radiation perforated area, rapid heat dissipation, good heat dissipation effect; 2) be provided with some arc-shaped through-holes at the groove outside, end plates, dispel the heat faster good heat dissipation effect; 3) be provided with the reinforcement boss between adjacent two arc-shaped through-holes, strengthen boss and extend to sidewall, guarantee that sidewall also has enough intensity after perforate.
Description of drawings:
Fig. 1 is prior art end cap stereogram;
Fig. 2 is the stereogram of the utility model end cap;
Fig. 3 is another angle stereogram of the utility model end cap.
Embodiment:
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Embodiment one: as shown in Figures 2 and 3, the utility model is a kind of motor stretching end cover, comprise end cap body 1, form cavity 11 in the middle of the end cap body 1, the bottom of end cap body 1 is provided with opening 12, and the top arranges end plates 13, be recessed to form groove 130 in the middle of the end plates 13 downwards, form base plate 136 in groove 130 bottoms, bearing pedestals 131 protruding upward in the middle of the base plate 136 are provided with some louvres 133 at the sidewall 132 of base plate 136 outsides, groove 130.
Embodiment two: the basis at embodiment one increases following technical characterictic: be provided with some arc-shaped through-holes 134 at groove 130 outsides, end plates 13.
Embodiment three: the basis at embodiment two increases following technical characterictic: be provided with between adjacent two arc-shaped through-holes 134 and strengthen boss 135, strengthen boss 135 and extend to sidewall 132.
Embodiment four: the basis at embodiment one or embodiment two or embodiment three increases following technical characterictic: some louvres 133 are 16, are divided into 4 groups and are distributed on the sidewall 132.
Embodiment five: embodiment two or the basis increase following technical characterictic: some arc-shaped through-holes 134 are 4, are distributed on the base plate 13.
Embodiment six: the basis at embodiment one increases following technical characterictic: end cap body 1 is hat-shaped.
Because the application is mechanical field, the apparent association of ability those of ordinary skill obtains: the technical characterictic independent assortment of the increase that embodiment two, embodiment three, embodiment four, embodiment five and embodiment six mention is combined into new technical scheme with the technical scheme of embodiment one.
Louvre 133 on the utility model sidewall 132 is made for the ease of mould, the front operation that stretches need to be reserved the hole of all cloth of a circle, because the shape in hole has moderate finite deformation after being drawn into skew wall, need to consider deflection, the louvre 133 of finally finishing is shaped as water-drop-shaped, streamlined, narrow trapezoidal, cashew nut shape, rectangle etc.
