Abstract
The utility model aims at providing a plastic sealed motor, which is simple in end cover structure, simple and convenient in matching process and high production efficiency. The plastic sealed motor comprises a plastic sealed casing, a rotor and an end cover. The rotor is located in a cavity in the middle of the plastic sealed casing, the end cover covers the opening end of the plastic sealed casing, the end cover is provided with a groove matched with the plastic seal casing, the length of the inner side wall of the groove in the axial direction is larger than the length of the outer side wall of the groove, and the inner side wall is in interference fit with the inner wall of the opening end of the plastic sealed casing.
Description
Technical field
The utility model relates to machine field, especially a kind of plastic packaging motor.
Background technology
Plastic packaging motor is to adopt plastic package technology that usefulness engineering plastics (like BMC) such as the stator core of motor, winding are carried out overall package, cancels the traditional motor stator insulated treatment process and the metal chassis of common electric machine.Its rotor is positioned at the cavity in the middle of the plastic packaging housing, and end cap covers the opening end of plastic packaging housing.Adhesion after cooperating between end cap and plastic packaging housing need reach certain requirement, can not satisfy the requirement of its performance index otherwise motor vibrations, thermal shock or long-term operation rear end cap possibly become flexible.
Existing a kind of end cap is as depicted in figs. 1 and 2, and end cap 1 has groove 11, the madial wall of groove 11 12 and lateral wall 13 rotor axially on equal in length, the outer rim of end cap 1 is provided with boss 14, which is provided with seam 15.During with the plastic packaging shell, need on the plastic packaging housing, to hole earlier, be pressed into end cap 1 and plastic packaging housing interference fit with special tooling then, then in the hole on seam 15 rivetings to the plastic packaging housing.The shortcoming that this kind mode cooperates is that end cover structure is complicated and cooperate technology complicated, and the location is very difficult when on the plastic packaging housing, holing, and efficient is low and scrappage is high, and when the riveting seam, is easy to occur bad order.This kind cooperation is non-removable in addition, in case the parts of motor internal damage to some extent, whole plastic packaging motor will go out of use, and cause great waste.
Summary of the invention
The purpose of the utility model provide a kind of end cover structure simple, cooperate the plastic packaging motor that technology is easy and production efficiency is high.
For realizing above-mentioned purpose, the scheme that the utility model provides is:
[z1] motor; Comprise the plastic packaging housing, rotor and end cap, rotor are positioned at the cavity in the middle of the plastic packaging housing; End cap covers the opening end of plastic packaging housing; End cap has the groove with the plastic packaging shell, and the length of the madial wall of groove is greater than the length of the lateral wall of groove in the axial direction, the inwall interference fit of madial wall and plastic packaging housing opening end.
The length of the madial wall of the groove through making end cap has promptly increased the area of end cap and plastic packaging shell greater than the length of the lateral wall of groove, makes it can satisfy the fastening requirement of end cap and plastic packaging housing.Cancelled boss and seam on the end cap, also need not on the plastic packaging housing, to hole, thereby made the simple in structure of plastic packaging motor, production efficiency increases.
More concrete scheme is: the outer wall that connects opening end in the lateral wall of groove.The lateral wall of groove and the non-interference fit of plastic packaging housing outer wall make end cap be easy to dismounting, and convenient parts to plastic packaging motor inside overhaul, and practice thrift cost.
Another more concrete scheme is: the step surface that the outer wall of opening end contracts in being provided with radially, step surface height diametrically is greater than the thickness of groove lateral wall.After end cap and plastic packaging shell, the height of groove lateral wall is lower than the height of the non-mating part of plastic packaging housing, thereby the certain protection effect is stamped in plastic packaging housing opposite end, makes mating part be difficult for being collided, and then can not influence the fastening of end cap and plastic packaging housing.
Description of drawings
Fig. 1 is the front view of the end cap of existing plastic packaging motor;
Fig. 2 is the B-B cutaway view of Fig. 1;
Fig. 3 is the structure chart of the utility model plastic packaging motor;
Fig. 4 is the cutaway view of the utility model end cap.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 3; Plastic packaging motor comprises plastic packaging housing 2; Stator and winding thereof are encapsulated in the plastic packaging housing 2; The step surface 21 that the outer wall of plastic packaging housing 2 opening ends contracts in being provided with radially, rotor 4 and rotating shaft 41, bearing 42 etc. are through the opening end plastic packaging housing 2 of packing into, and end cap 3 covers the opening end of plastic packaging housings 2.Because the existence of step surface 21, end cap 3 is with after plastic packaging housing 2 cooperates, and the non-mating part of its lateral surface and plastic packaging housing has difference in height h, thereby end cap receives the protection of plastic packaging housing 2 and is difficult for being collided.
As shown in Figure 4; The central part of end cap 3 is provided with the bearing chamber 31 that holds bearing 42; Its outer rim is provided with interconnective towards the outside export-oriented groove 32 of plastic packaging motor with towards inner interior to groove 33 of plastic packaging motor, be the groove that cooperates with plastic packaging housing 2 opening ends to groove 33 in wherein, and is interior to the inwall 34 of groove 33 and the inwall interference fit of plastic packaging housing 2 opening ends; The interior outer wall that in the outer wall 35 of groove 33, connects plastic packaging housing 2 opening ends, inwall 34 is than the long in the axial direction L of outer wall 35.Compare with the structure of prior art end cap, the degree of depth of export-oriented groove 32 strengthens, thereby inwall 34 is extended relatively, and the interference fit face increases.
When end cap 3 to plastic packaging housing 2 was installed, elder generation carried out shaping to end cap 3 through the shaping frock, thereby controlled end cap 3 and plastic packaging housing 2 adhesions, directly was pressed into end cap 3 with aerostatic press then to get final product.When finding that plastic packaging motor inside goes wrong like bearing 42 parts such as grade, available dismounting frock disassembles end cap 3, and the end cap 3 that is pressed into again through shaping after its inner components maintenance is finished can continue to use.
More than be the preferred embodiment of the utility model, the utility model includes but not limited to this, and the technical scheme of modes such as all employing equivalent transformations all drops in the protection range of the utility model.
