Abstract
The utility model discloses a motor end cover. The motor end cover comprises an end cover body. Multiple installing sheets are disposed on the outer edge of the end cover body. A circular groove used for fixing a motor rotor is disposed on the center of the end cover body. Multiple projections are disposed on the circumferential radial direction of the inner surface of the circular groove. A bearing in cooperation with a motor rotor is fixedly disposed on the projections. The motor end cover with reasonable structural design and strong applicability not only guarantees the fastening performance between the end cover and a motor housing, but also reduces the number of additional parts in order to effectively achieve assembling precision between the bearing in cooperation with the motor rotor and the end cover.
Description
Technical field
The utility model relates to end cap, relates in particular to a kind of end cap that is applied on the motor.
Background technology
Motor is the general name of conversion equipment between mechanical energy and the electric energy, and most motor application principle is electromagnetic induction principle.In order to protect motor, usually need an end cap be installed at motor in the reality, this end cap not only plays and prevents external force to the hurtful effect of motor, and plays the usefulness of the normal operation of support motor rotor and machine shaft.But in the middle of real work, electric motor end cap also comes with some shortcomings: 1, end cap cooperates not tight with casing, loosening easily, electric motor end cap all cooperates fastening by card base is set with motor case mostly at present, thereby make end cap and casing can't be completely fixed together, can not bear the vibrations of motor when work effectively, occur easily becoming flexible, cause certain danger; 2, knownly, end cap is useful on the usefulness of fixed electrical machinery stator and rotor, and generally all be to be connected and fixed by bearing is set between end cap and the rotor, in practice, the compactness of end cap and bearing becomes the problem that we need solve, and at present, uses more method a rubber bushing to be installed between end cap and bearing or some fastening parts are set exactly, this method has solved the precision of end cap assembling bearing portion, but has but increased equipment part and assembling procedure.
At the above-mentioned background technology, the utility model is concentrated and has been obtained solution.
The utility model content
The purpose of this utility model is the problem of mentioning in the above-mentioned background technology in order to solve, and a kind of electric motor end cap is provided.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of electric motor end cap, comprise the end cap body, described end cap body outer is provided with several installation sheets, described end cap body center offers a circular groove that is used for the fixed electrical machinery rotor, the circumference of described circular groove inner surface directly upwards arranges a plurality of projectioies, is set with a bearing that cooperates with rotor on the described boss.
Further, equidistantly distribute around the end cap body between the described installation sheet.
Further, described installation sheet is provided with the nut installing hole.
Further, described end cap body is discoid.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, a kind of electric motor end cap that the utility model proposes can cooperate with motor case closely, is difficult for taking place loosening.Electric motor end cap of the present utility model, comprise the end cap body, this end cap body outer is provided with several installation sheets, equidistantly distribute between these installation sheets around the end cap body, thereby namely overcome the defective that the available technology adopting card base brings, can cooperate closely with the motor case installation again, simplify operational sequence, improved production work efficient.
2, a kind of electric motor end cap that the utility model proposes, by when casting end cap, in end cap body central circular groove, be provided with a plurality of projectioies, this projection is arranged on the interior same circumference of this circular groove, this projection mainly plays the usefulness of rigid bearing, in the prior art, operated by rotary motion has a securing member that increases frictional force between bearing and the groove inwall, thereby the projection of the utility model setting namely replaced additional assembling parts of the prior art, guaranteed again must assemble precision between rotor, bearing, the groove.
3, the utility model reasonable in design, applicability is strong.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation in the present embodiment;
Reference numeral: 1-end cap body; The 2-installation sheet; The 3-groove; The 4-projection; The 5-bearing; 6-nut installing hole.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with Fig. 1, a kind of electric motor end cap, comprise end cap body 1, this end cap body 1 outer is provided with several installation sheets 2, its end cap body 1 center offers a circular groove 3 that is used for the fixed electrical machinery rotor, the circumference of these circular groove 3 inner surfaces directly upwards arranges a plurality of protruding 4, is set with a bearing that cooperates with rotor 5 on these projection 4 positions.
In the present embodiment, this end cap body 1 outer is provided with four installation sheets 2, this installation sheet 2 and end cap body 1 are by welding or being articulated and connected, in the present embodiment, this installation sheet 2 is provided with nut installing hole 6, be used for end cap is cooperated fastening usefulness with motor case, overcome the defective that the available technology adopting card base brings by this setting, can effectively end cap and motor case be closely connected, not only play positioning action, and can bear the vibrations that motor produces effectively by fastening when working.
In the present embodiment, equidistantly distribute around end cap body 1 between these four installation sheets 2, in actual applications, can also adopt a plurality of installation sheets 2.
In the present embodiment, in order to ensure on the one hand for the bearing 5 and end cap groove 3 ground assembly precisions that cooperate with rotor, can save additional assembling parts of the prior art on the one hand again, the utility model is provided with a plurality of protruding 4 in end cap body 1 central circular groove 3, these projection 4 parts are equipped with bearing 5, and this projection 4 has increased the friction between bearing 5 and the groove 3, thereby improved the precision of bearing 5 with 3 assemblings of end cap groove, saved part and assembling procedure.
In the present embodiment, this end cap body 1 is discoid.
A kind of electric motor end cap that proposes in the utility model, reasonable in design, applicability is strong, has both ensured the tightness between end cap and the motor case, can reduce add-on parts again and make for obtaining assembly precision effectively between the bearing that cooperates with rotor and the end cap.
The above only is preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing, is equal to replacement etc. in protection range of the present utility model, all should be included within the protection range of the present utility model.
