Abstract
The utility model discloses an improved motor end cover. The improved motor end cover comprises an end cover body equipped with two middle shafts. The middle shafts comprise a top middle shaft and a bottom middle shaft. The diameter of the top middle shaft is less than that of the bottom middle shaft. The top middle shaft, the bottom middle shaft, and the end cover body form an integrated structure. In the improved motor end cover, the top middle shaft and the bottom middle shaft which form the middle shafts and the end cover body are produced by using integrated structure. Therefore, the integral concentricity of the top middle shaft and the bottom middle shaft is guaranteed. The improved motor end cover has characteristics of simple technology, reduced all processes of secondary technology, and saved technology cost and component cost.
Description
Technical field
The utility model relates to a kind of improved electric motor end cap.
Background technology
The jack shaft of original motor front end housing forms after being pressed into by follow-up frock by two metalwork jack shafts that separate, its shortcoming is that to be pressed into rear concentricity by secondary assembling poor, complex process, error rate and to go out time rate high requires high to tooling device and parts cost and operation employee.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of improved electric motor end cap be provided, solve in the past the motor front end cover packaging technology complicated, to frock and parts and the demanding defective of operator.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of improved electric motor end cap, comprise the end cap body, be provided with 2 jack shafts on the described end cap body, described jack shaft comprises jack shaft and lower jack shaft, the diameter of described upper jack shaft is less than the diameter of lower jack shaft, and described upper jack shaft, lower jack shaft and end cap body are structure as a whole.
Further, be respectively arranged with oil groove on the outer ring face of described upper jack shaft and lower jack shaft, described each oil groove is circumferentially uniform along upper jack shaft and lower jack shaft outer ring face.
The beneficial effects of the utility model are: a kind of improved electric motor end cap is provided, make forming between the upper jack shaft of jack shaft and lower jack shaft and the end cap body employing integrative-structure, guaranteed the concentricity of upper and lower jack shaft integral body, and technique has also become simply, reduce all processes of secondary processes, saved the advantage of process costs and parts cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of electric motor end cap;
Wherein: 1, end cap body, 2, jack shaft, 3, oil groove, 21, upper jack shaft, 22, lower jack shaft.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of improved electric motor end cap, comprise end cap body 1, be provided with 2 jack shafts 2 on the end cap body 1, jack shaft 2 comprises jack shaft 21 and lower jack shaft 22, the diameter of upper jack shaft 21 is less than the diameter of lower jack shaft 22, and upper jack shaft 21, lower jack shaft 22 and end cap body 1 are structure as a whole.So, guaranteed the concentricity of upper and lower jack shaft integral body, and technique become simply also, reduced all processes of secondary processes, saved the advantage of process costs and parts cost.
In order to improve the greasy property of jack shaft 2, be respectively arranged with oil groove 3 on the upper jack shaft 21 in the jack shaft 2 and the outer ring face of lower jack shaft 22, each oil groove 3 is circumferentially uniform along upper jack shaft 21 and lower jack shaft 22 outer ring faces.
In order to make the gear that is installed on the jack shaft 2 can be more stable, the end cap body 1 in axle 2 outer rings that mediate be formed with a circle groove, makes the gear of installation more stable.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
