Abstract
The utility model discloses a miniature motor end cap having a heat radiation function. The miniature motor end cap comprises an annular end cap main body, wherein the center of the annular end cap main body is provided with a round shaft hole; an annular projection is disposed on an inner side of the end cap main body and on a periphery of the round shaft hole; an annular edge hoop is disposed at an edge of the annular end cap main body on the periphery of the annular projection; the annular edge hoop is provided with air holes; a cavity is formed between the annular edge hoop and the annular projection; arc-shaped ribs are uniformly distributed in the cavity; outer side ends of the arc-shaped ribs are fixedly connected with the annular edge hoop; and gaps are formed between inner side ends of the arc-shaped ribs and the annular projection. Since the arc-shaped ribs are uniformly distributed in the cavity between the annular edge hoop and the annular projection, the outer side ends of the arc-shaped ribs are fixedly connected with the annular edge hoop, and gaps are formed between the inner side ends of the arc-shaped ribs and the annular projection, air flow generated at an end portion projection when a motor rotor rotates flows to the air holes along the arc-shaped ribs, and then is exhaust to the outside of a motor, and thus heat of the motor is radiated, and energy consumption is reduced.
Description
Technical field
The utility model relates to the micromachine field of components, is specifically related to a kind of micro motor end cover with heat sinking function.
Background technology
The end cap of micromachine has two, is to be fixed on the two ends of stator in order to carry rotor and motor is installed on the frame.After micro motor end cover is installed in the two ends of micromachine casing, generally speaking, the outer wall of end cap just in time with the outer wall of motor case to it, i.e. the equal diameters of the external diameter of end cap and casing.Have axis hole in the middle of the end cap, pass in order to the main-shaft spindle head with motor stator and to expose, in order to be connected with external loading, around the axis hole of end cap inboard, be provided with an annular protrusion, the outer wall precision-fit of inwall and bearing by annular protrusion is fixed the bearing on the spindle nose.Seal between existing micro motor end cover inboard and the rotor, such structure is not only so that during bearing operation, the heat that the bearing that runs up produces is difficult in time dissipating, be delivered to motor stator and make its heating, for heat is in time dissipated, manufacturer's majority is to adopt spindle nose in the end cap outside to install cooling wind blade additional it is dispelled the heat, and so not only can increase to produce thus and use cost, also can increase simultaneously the energy consumption of motor, thereby cause unnecessary waste.
The utility model content
For solving the problems of the technologies described above, we have proposed a kind of micro motor end cover with heat sinking function, to be able in time to dispel the heat minimizing energy consumption, reduction production and use cost, and the purpose of long service life as motor.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of micro motor end cover with heat sinking function comprises an annular end cap main body, and described annular end cap main center has a circular axis hole, and described end cap main body inner circular axis hole is arranged with an annular protrusion outward; The annular end cap body rim place of described annular protrusion periphery is provided with the annular edge hoop, and described annular edge hoop is provided with air-vent; Form a cavity between described annular edge hoop and the described annular protrusion, be evenly equipped with arc flange in the described cavity, and the arc flange outboard end is fixedly connected with described annular edge hoop, leave the gap between its medial extremity and the described annular protrusion.
Preferably, described air-vent is located on the annular edge hoop between the adjacent described arc flange outboard end.
Preferably, described air-vent is trapezoidal, and is distributed on the described annular edge hoop.
Pass through technique scheme, the utility model is by evenly being laid with arc flange in the cavity between described annular edge hoop and described annular protrusion, and the arc flange outboard end is fixedly connected with described annular edge hoop, leave the gap between its medial extremity and the described annular protrusion, its end nipple source produces air-flow and flows to air-vent along between the arc flange when making the rotor running, discharge again beyond the motor, the heat of motor in time can be dissipated, reduced energy consumption, reduce and produce and use cost, and effectively prolonged the useful life of motor, thereby reached reasonable in design, simple in structure, and the purpose that effect is good.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of micro motor end cover with heat sinking function, to be able in time to dispel the heat minimizing energy consumption, reduction production and use cost, and the purpose of long service life as motor.
Below in conjunction with embodiment and embodiment the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of micro motor end cover with heat sinking function comprises an annular end cap main body 1, and described annular end cap main body 1 center has a circular axis hole 2, the described end cap main body 1 inner circular axis hole 2 outer annular protrusions 3 that are arranged with; Annular end cap main body 1 edge of described annular protrusion 3 peripheries is provided with annular edge hoop 4, and described annular edge hoop 4 is provided with air-vent 5; Form a cavity between described annular edge hoop 4 and the described annular protrusion 3, be evenly equipped with arc flange 6 in the described cavity, and arc flange 6 outboard ends are fixedly connected with described annular edge hoop 4, leave the gap between its medial extremity and the described annular protrusion 3.
Wherein, described air-vent 5 is located on the annular edge hoop 4 between adjacent described arc flange 6 outboard ends; Described air-vent 5 is trapezoidal, and is distributed on the described annular edge hoop 4.
In this example, after the electric motor end cap in this case is installed on the micromachine, because there is highlight at the two ends of rotor cylinder cylindrical surface, its end nipple source just can blocks air when rotor turns round, produce air-flow and flow to air-vent 5 along between the arc flange 6, discharge again beyond the motor, the heat in the motor is in time dissipated, temperature is reduced to satisfactory temperature.
