Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of integrated motor end cap.
Background technology
The motor of prior art has following defect:
A, the confidential normal work of direct current, be unable to do without brush basin, brush carrier, brace and two end caps etc., thereby materials are many, part is many;
B, function are simple, and each part has been born more single function: end cap can only support stator, lay bearing; Brush basin is laid brush carrier, electric component;
C, manufacturing procedure are many: except each part has multi-step process, also will increase the operation of installing and locating a plurality of brush carriers, brace.
Brace heat radiation is good not: brush basin structure, brace are embedded in brush basin body interior, are unfavorable for heat radiation.
D, cumulative limit are large: the product that a plurality of different materials form, is difficult to ensure dimensional accuracy very accurately.
E, brush are in brush carrier (material is copper), its shortcoming:
(a), price many with copper, brush heat radiation is good not, and after the machine operation time grown, and under moist environment, brush is likely blocked by carbon dust in brush carrier.
(b) axial distance of motor is by brush carrier thickness and due gap certain axial distance that accounted for.
Utility model content
The purpose of this utility model, exactly in order to address the above problem, provides a kind of novel integrated motor end cap.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of integrated motor end cap, comprise end cap body, also comprise with the integrated two groups of inductance geometrical clamps of end cap body, terminal clamp and four groups for the spill guide rail of brush is installed; In the centre of end cap body, be provided with fixed leg or the bearing chamber for fixed electrical machinery axle, at end cap body, be circumferentially with three for through the Kong Zhu of mounting screw, on end cap body, be provided with a plurality of louvres, a plurality of reinforcement and two for the groove of ground strip is installed, in fixed leg, be embedded with spring.
Also comprise at least one electric capacity geometrical clamp.
Described spill guide rail comprises two guide rails, between two guide rails, form arc spring chamber, the head of arc spring chamber is provided with step, in case stage clip ejects, wherein a slice guide rail is provided with for by the elongated slot of brush-lead, the outer end of spill guide rail is provided with the marmon clamp as spring base, is formed for the open slot of fixing spring one end between marmon clamp and spill guide rail body.
Described reinforcement comprises the ring stiffener that four groups of spill guide rails are connected in series, and is out of shape and two for laying posting inductance leads and brush-lead and head on ring stiffener.
The surrounding of described fixed leg is provided with triangle reinforcement.
Described terminal clamp both sides are respectively equipped with lug, and centre is provided with more than half cylinder.
The back side of described end cap is provided with end cap reinforcement, comprises and is many radial reinforced ribs of dispersion shape setting and the ring stiffener that each radial reinforced rib is coupled together.
The both sides, outer end of described each spill guide rail are respectively equipped with reinforcing prop.
Compared with prior art, the utlity model has following advantage:
1, integrated degree is high, has advantages of that part is few, material is few, lightweight, volume is little, axial distance is short:
Brush basin, end cap, brush carrier, inductance folder, gusset are integrated, in the hole at the middle part of end cap (with spring), be pressed into axle interference fit, axle is connected with bearing inner race, and drive armature to turn round by bearing outer ring, thereby saved front end housing, thereby motor of its assembling use can save brush basin, brush carrier, inductance folder, stator gusset, front end housing etc., certainly also saved material, make the motor weight saving being assembled into; Saved brush basin, brush carrier, front end housing, thereby had advantages of that volume is little, axial distance is short.
2, have advantages of that function is many, good manufacturability, dimensional accuracy be high:
Only an end cap is born several functions, has fixing, location various parts, supports stator and rotor, serves as the function of brushing basin; There is no brace as inserts, Shooting Technique is good; The matching relationship that there is no a plurality of parts, manufacturing procedure is few, cumulative limit is little, therefore dimensional accuracy is high.
3, there is good performance (mechanical performance, comfortableness, insulating properties):
Adopt the plastic material of good rigidly, at key position and weakness (consideration material-saving) position of end cap, add reinforcement simultaneously, thereby the smooth difficult bent distortion of rectifying of end cap;
Good rigidly adds that the motor being assembled into that makes firm in structure can have good axiality and no-float, thereby motor noise is little, and comfortableness is good;
Part has corresponding geometrical clamp or mounting groove fix and locate, and avoids interfering and rocking the abnormal sound causing;
Plastic end cover has good insulating properties, the fine isolate conductive sheet of energy, brush etc. and metalwork (stator cage).
4, good heat dissipation, reliability is high, the life-span is long:
Brush fluting is in spill guide rail, without the encirclement of brush carrier, so brush good heat dissipation;
Have certain louvre and do not brush basin, there is no front end housing, the radiating condition of armature is better, thereby has improved the useful life of motor;
The defect that this structure avoids brush to be blocked by carbon dust, thereby the reliability of brush work is high;
Because spill guide rail and marmon clamp are the plastic materials of end cap self, this creepage distance having in the time of need not considering to switch on (copper brush of traditional structure is held with stator cage needs certain space length), thereby spill guide rail can be done to obtain long enough as required, brush can correspondingly extend, thereby improves its useful life;
Lay the arc spring chamber that spring is used, the marmon clamp of the effect of start-stop extractor, can prevent that stage clip from departing from deep-slotted chip breaker.
Owing to being once-forming, dimensional accuracy is easy to guarantee, can makes brush and spring reliablely and stablely work;
The arc spring chamber of one side has elongated slot, on the one hand can be used for brush cabling, can locate on the other hand the lead-in wire of brush, avoids the interference of the lead-in wire of brush and armature etc.; If axially there is certain space, brush-lead also can be in the outside of spill guide rail.
Together with the fixed leg of end cap central authorities is injection-moulded in spring, improve intensity herein, can reduce the risk into axle plastics cracking, added that reinforcement is further to improve its rigidity, the perpendicularity that is in axle is wherein guaranteed, thereby avoids the interference of armature and stator.
