Abstract
The utility model discloses a machining-free motor end cover. The machining-free motor end cover comprises a cover body which is molded through die-casting; the cover body comprises a bearing chamber which is arranged in a manner that the bearing chamber is coaxial with the cover body, and a plurality of rabbet structures; the bearing chamber is in clearance fit with a bearing arranged inside the bearing chamber; and the rabbet structures are in clearance fit with a motor casing. By means of the above manner, the machining-free motor end cover of the utility model is simple and reliable in structure; the bearing component can be directly assembled without machining required; the machining-free motor end cover is low in cost, the sizes of the bearing chamber, the rabbets and the like do not require machining, such that machining cost can be saved, and turnover can be avoided; the machining-free motor end cover is high in precision, and form and position tolerances of the bearing chamber and the matched rabbets can be guaranteed directly through a mould and die-cast molding, such that unqualified rate and reject ratio caused by the machining can be reduced, and therefore, a motor has more stable performance and better consistency.
Description
Technical field
The utility model relates to field of motor manufacturing, particularly relates to a kind of electric motor end cap of exempting to process.
Background technology
Induction machine is widely used in various office equipment, plant equipment, water pump, various occasions such as household electrical appliance; Exempt to process a kind of lower cost solution that is used for substituting finish turning processing electric motor end cap of electric motor end cap.
Electric motor end cap all is to adopt cast aluminium or cast iron end cap through the moulding of high precision numerical control machined into for a long time, and to want the bearing chamber bearing be that benchmark is processed other positioning spigot and benchmark, difficulty of processing is big, and wastes time and energy, and is the technical bottleneck of this lower cost solution always.
The utility model content
The technical problem that the utility model mainly solves provides a kind of electric motor end cap of exempting to process, can cooperate and high-precision aluminium die casting by structural design and size, guarantee the precision of oiliness bearing chamber with mould and design, and the form and position tolerance of bearing chamber and positioning spigot etc., accomplish real exempting from processing and reach design accuracy and instructions for use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of electric motor end cap of exempting to process is provided, comprise: the lid of die cast, comprise the bearing chamber, a plurality of fixing structure that arrange with described lid concentric on the described lid, described bearing chamber is matched in clearance with the inner bearing that arranges, and is connected for interference fit between described fixing structure and the motor case.
In preferred embodiment of the utility model, described lid adopts the aluminium material die cast.
In preferred embodiment of the utility model, motor case is provided with a plurality of small boss, is connected with described seam interference fit by small boss.
In preferred embodiment of the utility model, described lid periphery is provided with a plurality of erecting beds, and described erecting bed is provided with bolt mounting holes.
The beneficial effects of the utility model are: it is simple and reliable that the utility model exempts to process motor end cap structure, need not to process direct running in bearings parts; Cost is low, and bearing chamber and seam equidimension all need not processing, save processing charges and turnover; Precision is higher, directly guarantees bearing chamber and the form and position tolerance that cooperates seam by mould and die cast, minimizing by processing cause defective with scrap, make motor performance more stable, consistency is better.
Description of drawings
Fig. 1 is the structural representation that the utility model exempts to process electric motor end cap one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, lid, 2, bearing chamber, 3, erecting bed, 4, bolt mounting holes, 5, seam.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises:
A kind ofly exempt to process electric motor end cap, comprise: the lid 1 of die cast, comprise the bearing chamber 2, a plurality of seam 5 structures that arrange with described lid 1 concentric on the described lid 1, described bearing chamber 2 is matched in clearance with the inner bearing that arranges, and is connected for interference fit between described seam 5 structures and the motor case.
Described lid 1 adopts the aluminium material die cast.Directly guarantee bearing chamber 2 and the form and position tolerance that cooperates seam 5 by mould and die cast, minimizing by processing cause defective with scrap, make motor performance more stable, consistency is better.
Motor case is provided with a plurality of small boss, is connected with described seam 5 interference fit by small boss.Assemble simple and reliablely, save complicated procedures of forming such as many location.
Described lid 1 periphery is provided with a plurality of erecting beds 3, and described erecting bed 3 is provided with bolt mounting holes 4.By bolt mounting holes 4 whole lid 1 is fixed on the motor.
It is simple and reliable that the utility model exempts to process motor end cap structure, need not to process direct running in bearings parts; Cost is low, and bearing chamber 2 and seam 5 equidimensions all need not processing, save processing charges and turnover; Precision is higher, directly guarantees bearing chamber 2 and the form and position tolerance that cooperates seam 5 by mould and die cast, minimizing by processing cause defective with scrap, make motor performance more stable, consistency is better.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
