Abstract
The utility model discloses a motor end cover which comprises a cover body (1), wherein the cover body (1) is provided with a rotating shaft hole (2); riveting platforms (3) for riveting an inner small cover are evenly distributed around the rotating shaft hole (2); and the riveting platforms (3) are located inside the cover body (1). The existing stamping die for the end cover can be improved by directly stamping the riveting platforms (3) inside the end cover when the end cover is stamped. The riveting platforms (3) are shown as Fig . 1 and Fig . 2; and the riveting platforms are bosses formed inside the end cover through stamping blind holes 4 outside the end cover by the die. The diameter d of the riveting platforms 3, the diameter D of the circle formed by the evenly-distributed riveting platforms and the number of the riveting platforms respectively correspond to the diameter of the riveting holes on the inner small cover, the diameter of the circle formed by the evenly-distributed riveting holes and the number of the riveting holes; and the height of the riveting platforms is larger than the thickness of the riveting holes on the inner small cover so as to ensure the reliability of riveting.
Description
Technical field
The utility model relates to a kind of electric motor end cap, belongs to the motor bearings technical field of sealing technology.
Background technology
The rotor of motor and the junction of end cap are provided with rotor bearing.Rotor bearing passes through the fixedly rotor hole place of end cap inboard of interior tegillum.Be uniformly distributed with riveted holes along the circumference on the interior tegillum, also be evenly equipped with around the shaft hole of end cap with interior tegillum on the corresponding riveted holes of riveted holes, interior tegillum is riveted together by rivet and electric motor end cap.
Present this syndeton, because end cap is provided with riveted holes, rivet and riveted holes are always gapped, lubricating oil in the interior tegillum oozes out from the gap between rivet and the riveted holes easily, the motor carbonated drink that close property is had relatively high expectations is infiltrated motor internal the gap between rivet and riveted holes easily makes motor internal make moist poor sealing easily.Present structure need be placed on rivet in the riveted holes and rivet, and rivet is very little, need carefully be placed in the riveted holes and then rivets, and careless rivet can fall down from riveted holes, and riveting is trouble, and efficient is low.
The utility model content
The purpose of this utility model is, a kind of electric motor end cap is provided.Can prevent that lubricating oil from oozing out and carbonated drink infiltration motor internal from end cap.But and simplified processing process, enhance productivity.
The technical solution of the utility model: a kind of electric motor end cap, comprise lid, lid is provided with shaft hole; Be evenly equipped with the riveting platform of tegillum in being used to rivet around the shaft hole, the riveting platform is positioned at the lid inboard.
In the aforementioned motor end cap, the height H between the summit of described riveting platform and the lid inner surface is greater than the thickness at riveted holes place on the interior tegillum.
In the aforementioned motor end cap, the diameter d of described riveting platform is corresponding with the riveted holes diameter on the interior tegillum.
In the aforementioned motor end cap, the uniform diameter D of described riveting platform is corresponding with the uniform diameter of riveted holes on the interior tegillum.
Compared with prior art, the utility model is at the riveting platform of the inboard boss that forms of end cap as tegillum in connecting, directly with interior tegillum and end cap riveted joint with the punching press blind hole.Owing to do not have the hole on the end cap, seal fully, can prevent the oil seepage and the carbonated drink infiltration motor internal of rotor bearing.Connect owing to need not rivet,, save production cost so can save the rivet expense.Simplified processing technology, can enhance productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1;
Fig. 3 is the schematic diagram of Fig. 1 other direction.
Being labeled as in the accompanying drawing: 1-lid, 2-shaft hole, 3-riveting platform, 4-punching press blind hole.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.A kind of electric motor end cap, as shown in Figure 1, a kind of electric motor end cap comprises lid 1, lid 1 is provided with shaft hole 2; Be evenly equipped with the riveting platform 3 of tegillum in being used to rivet around the shaft hole 2, riveting platform 3 is positioned at lid 1 inboard.
As shown in Figure 2, the height H between the summit of described riveting platform 3 and lid 1 inner surface is greater than the thickness at riveted holes place on the interior tegillum.The diameter d of described riveting platform 3 is corresponding with the riveted holes diameter on the interior tegillum.Riveted holes quantity is more than riveting platform quantity on the interior tegillum, and unnecessary hole is as the location hole on the riveted joint mould.As shown in Figure 3, the uniform diameter D of described riveting platform 3 is corresponding with the uniform diameter of riveted holes on the interior tegillum.
Implementation process of the present utility model and principle
The utility model can improve by the diel to existing end cap, directly goes out riveting platform 3 in the inboard of end cap when the punching press end cap.Described riveting platform 3 as depicted in figs. 1 and 2, the riveting platform be with mould in end cap outside punching press blind hole 4 at the inboard boss that forms of end cap.The quantity of the diameter d of riveting platform 3 and uniform circular diameter D and riveting platform is all corresponding with riveted holes diameter and uniform circular diameter and quantity on the interior tegillum, and the height H of riveting platform should be greater than the thickness at riveted holes place on the interior tegillum, to guarantee the reliability of riveted joint.
Because riveting platform 3 is that punching press blind hole 4 is at the inboard boss that forms of end cap.So the steel plate of end cap is not dashed logically when punching press, so seal finely, the lubricating oil in the interior tegillum will not ooze out from the gap between rivet and the riveted holes and carbonated drink is infiltrated motor internal.Owing to during assembling, no longer need to connect,, save production cost so can save the rivet expense with rivet.Simplified processing technology, can enhance productivity.
