Abstract

The utility model belongs to technical field of motor manufacture, more particularly to a kind of motor end cover component.The component includes the end cap of step-shaped transition structure, matching is equipped with bearing on the inside of the end face of end cap, felt circle is set between bearing outside surface and end cap, pressed from both sides between the interior aspect face of bearing and end cap embedded with bearing with end cover, circumferential uniform zigzag structure is set on described end cap outward flange, and described end cap is interference fitted by zigzag structure and casing.The utility model is interference fitted using broached-tooth design and casing, eliminates the gap between end cap and casing, ensure that the front and rear and casing of end cap will not produce gross distortion.The outer edge inside lateral bend, and multiple grooves are circumferentially laid with inward flange simultaneously of circular bearing with end cover folder, occurs elastic deformation in setting-in, is easily assembled, and lock it is firm.Thus, the utility model is simple in construction, convenient to implement, and is favorably improved the service life of end cap.

Description

A kind of motor end cover component

Technical field

The utility model belongs to technical field of motor manufacture, more particularly to a kind of motor end cover component.

Background technology

Between existing motor end cap structure, wherein end cap and bearing by stamping riveting together.And stamping riveting mistake Journey, electric motor end cap can be caused to damage, so as to reduce the service life of end cap.

Electric motor end cap and casing are that gap coordinates or is interference fitted, and gap, which coordinates, not to be eliminated with one heart, and pressing-in force is too big, difficult With assembling, the front and rear and casing of end cap is caused to produce gross distortion.Interference fits, either pine enter or tightly enter, be all difficult to reach Ideal effect.

Thus, research and design one kind is simple in construction, convenient to implement, and improves the motor end cap structure of service life, has It is of great significance.

The content of the invention

In view of the deficienciess of the prior art, the utility model provides a kind of motor end cover component, the component is using saw Toothing is interference fitted with casing, eliminates the gap between end cap and casing, ensure that the front and rear and casing of end cap will not produce Raw gross distortion.

The technical scheme that the utility model is taken to achieve the above object is：

A kind of motor end cover component, the component include the end cap of step-shaped transition structure, are matched on the inside of the end face of end cap Equipped with bearing, felt circle is set between bearing outside surface and end cap, is embedded between the interior aspect face of bearing and end cap There is bearing with end cover folder, circumferential uniform zigzag structure is set on described end cap outward flange, described end cap passes through zigzag Structure is interference fitted with casing.

As a further improvement, also set up the limited block being engaged with casing limited impression on described end cap outward flange.

As a further improvement, multiple heat emission holes are set on the end face of described end cap.

As a further improvement, described bearing with end cover folder is outer edge while the circular ring of inside lateral bend, Multiple grooves are circumferentially uniformly arranged on inward flange, multiple grooves that cave in circumferentially are uniformly arranged on outward flange.

As a further improvement, the groove is the combination of any of triangle, rectangle, trapezoidal, arc or two kinds Structure.

The utility model is interference fitted using broached-tooth design and casing, eliminates the gap between end cap and casing, is ensured The front and rear and casing of end cap will not produce gross distortion.The outer edge of circular bearing with end cover folder while inside lateral bend, And multiple grooves are circumferentially laid with inward flange, setting-in when elastic deformation occurs, be easily assembled, and lock it is firm.Cause It is convenient to implement and the utility model is simple in construction, and it is favorably improved the service life of end cap.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the utility model A-A section view figure structure schematic representation.

Fig. 3 is the structural representation of the utility model bearing with end cover folder.

Embodiment

Specific embodiment of the present utility model is made a detailed explanation below in conjunction with the accompanying drawings.

As shown in Figure 1-2, a kind of motor end cover component, the component includes the end cap 1 of step-shaped transition structure, in end cap 1 End face on the inside of matching bearing 2 is housed, felt circle 3 is set between the outer surface of bearing 2 and end cap 1, outside the inner side of bearing 2 Circumferential uniform zigzag structure is set between surface and end cap 1 on bearing with end cover folder 4, the described outward flange of end cap 1 5, described end cap 1 is interference fitted by zigzag structure 5 and casing；Also set up on the described outward flange of end cap 1 and limited with casing The limited block 6 of position fit depressions.Multiple heat emission holes 7 are set on the end face of described end cap 1.

As shown in figure 3, described bearing with end cover folder 4 is the circular ring of outer edge while inside lateral bend, inner edge Multiple grooves 8 are circumferentially uniformly arranged on edge, the groove 8 is any of triangle, rectangle, trapezoidal, arc or two kinds Combining structure；Multiple grooves 9 that cave in circumferentially are uniformly arranged on outward flange.
