Description
Technical field
The utility model is a kind of electric rotating machine, belongs to the renovation technique of electric rotating machine.
Background technology
Existing electric rotating machine when the installation dimension of customer requirement is excessive, requires need increase syndeton when excessive outside motor body as size E among Fig. 1 or size F, and case 3 promptly is installed on end cap 2, in order to effective increase installation dimension, satisfies customer requirement; As shown in Figure 1.Owing to the coefficient of expansion of material, the reasons such as variation of ambient temperature, old case internal diameter size Φ D control ratio is difficulty, shown in Fig. 4,5, do not have can strain slot to make way (or hole), the salient point that does not have the location, after being pressed into end cap 2, case 3 occurs relatively rotating or combine tension with end cap 2, causes the possibility of mechanicalness noise bigger; During actual production, need consideration variation of ambient temperature instantly, set the internal diameter size Φ D of case 3, brought a lot of troubles to production unit.
The utility model content
The purpose of this utility model is to consider the problems referred to above and syndeton that a kind of electric rotating machine is provided.The utility model is not only saved the space, cost is low, safe in utilization, easy to operate, long service life.
The technical solution of the utility model is: include motor body, supporting motor axle end cap, be arranged on the case in the end cap outside, wherein motor body is made and is useful on the inner groovy that end cap is installed, end cap is fitted in the inner groovy of motor body, and end cap is provided with as radially spacing spacing hole or defining flange, case with the corresponding position of the set spacing hole of end cap on be provided with flange or spacing hole, case is fitted on the end cap set spacing hole or defining flange by its set flange or spacing hole.
Cooperating between the set spacing hole of the set flange of above-mentioned case and end cap for guaranteeing its radially not counterrotating interference fits.
The axial contact-making surface of above-mentioned case and end cap is provided with elastic construction, and cooperating between end cap and the elastic construction is interference fit.
The outside of above-mentioned case also is equiped with the vibration-proof rubber circle.
Above-mentioned case adopts the plastic material integral molded plastic to be shaped.
The utility model is because the employing case is the structure that integral molded plastic is shaped, make it have the certain deformation ability, the older case of this elastic construction tolerance relaxes a lot, and size is controlled easily, is subjected to the cause influences such as variation of the coefficient of expansion, ambient temperature of material little; The utility model is compared the easier control of the quality of case in order to increase installing and locating length with the case that generally uses; Simultaneously, make the radially flange and the spacing hole of position-limiting action, eliminate relatively rotating between case and the end cap in the radially contact-making surface increase of case and end cap; Axial contact-making surface at case and end cap changes to deformable elastic construction, reduces case and is pressed into the mechanicalness noise that causes greatly because of the magnitude of interference behind the end cap, guarantees good contact the between case and the end cap, improves motor overall acceptability rate.Have easy to use, structural strength good, stay-in-grade characteristics.The utility model is that a kind of design is ingenious, function admirable, the syndeton of convenient and practical electric rotating machine.
