Abstract
The utility model relates to an integrated motor casing, belonging to the field of motor technology. The integrated motor casing comprises a support, the support comprises a housing and an end cap which is integrated with the housing via smooth transitional connection, a wire outlet is formed in the outer periphery of the housing close to the side of the end cap, a shaft through hole is formed in a revolution center of the end cap, the inner side of the end cap includes a second projection extending towards an inner cavity of the housing, and an inner cavity of the second projection is equipped with a boss. According to the utility model, the integrated motor casing can be molded via once die casting, motor assembly is simple, concentricity is good, processing is simple, appearance is beautiful, connection links are decreased, and connection rigidity of equipment is good. At the same time, a user can add an intermediate connecting flange according to installation requirements without worry about excessive operation noise and vibration caused by unreliable connection.
Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of integrated motor housing.
Background technology
The agent structure of common small-sized B14 motor comprises stator, rotor, end cap, rear end cap etc., in the situation that processing technology, assembly technology are all stable, the final motor of manufacturing generally can reach qualified.But, due to equipment machining accuracy difference, workman's misoperation, the reason such as procedure inspection is not strict, also often there will be larger percent defective.Especially the following small machine of the high 112mm in center, adopts die casting aluminium material support and end cap more, and because the material of aluminium is partially soft, the parts rigidity is poor, finally causes the shaft extension of finished product motor to be beated, noise, vibration etc. are defective.
In addition, some special industry users usually require multiple installation dimension general, in actual use, often can between B14 motor and final erection unit, set up middle adpting flange.It is connecting link in the middle of equipment increases together.Well imagine, complete equipment final installation accuracy, rigidity, the especially concentricity all utmost point is difficult to ensure card.Therefore the particularity that should small machine be installed for B14 in the design is suitably adjusted.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of integrated motor housing simple in structure, ingenious, rational is provided, end cap and the housing of this electric machine casing are one-body molded, effectively reduce connecting link, increase the motor integral rigidity, also reached simultaneously and simplified processing and the purpose of assembling.
The technical scheme provided according to the utility model: integrated motor housing, comprise support, be characterised in that: described support comprises housing and the end cap that is connected smoothly and is integrated with housing, offer wire hole near on the outer circumference surface of end cap one side on described housing, the centre of gyration of described end cap offers shaft outlet hole, the end cap inboard has second projection of extending to the housing inner chamber, and the described second protruding inner chamber is provided with boss.
As further improvement of the utility model, on described housing, around wire hole, be provided with circular the first projection.
As further improvement of the utility model, described end cap inboard also is provided with reinforcement, and reinforcement extends to the second high spot from the inner walls place.
As further improvement of the utility model, on described end cap outer wall, there is the embedded nut that is die cast as one with end cap.
Compared with prior art, advantage is the utility model: but support one-step die casting of the present utility model, the motor assembling is simple, good concentricity, and processing is simple, and good looking appearance reduces connecting link, and the equipment joint stiffness is good.Simultaneously the user can also be according to needs are installed, adpting flange in the middle of increasing, and do not worry connecting unreliable, cause equipment running noises and vibration excessive.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The left view that Fig. 2 is Fig. 1.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, comprise wire hole 1, reinforcement 2, embedded nut 3, boss 4, support 5, housing 6, end cap 7, the first projection 8, shaft outlet hole 9, the second projection 10 etc.
As Fig. 1, shown in Fig. 2, the utility model is the integrated motor housing, comprise support 5, described support 5 comprises housing 6 and the end cap 7 that is connected smoothly and is integrated with housing 6, offer wire hole 1 near on the outer circumference surface of end cap 7 one sides on described housing 6, the centre of gyration at end cap 7 offers shaft outlet hole 9, shaft outlet hole 9 parts are reserved suitable thickness, so that protection needs processing oil groove or oil sealing hole according to motor, end cap 7 inboards have second projection 10 of extending to housing 6 inner chambers, be provided with screw thread at the second protruding 10 inwalls, the described second protruding 10 inner chambers are provided with boss 4, with assurance, do not drilled.
Be provided with circular the first projection 8 around wire hole 1 on described housing 6.
Described end cap 7 inboards also are provided with reinforcement 2, and reinforcement 2 extends to the second protruding 10 places from housing 6 inwall places, and in practical operation, reinforcement 2 is traditionally arranged to be 4 ~ 8.
There is the embedded nut 3 that is die cast as one with end cap 7 on described end cap 7 outer walls, facilitate being dismounted for multiple times.
The utility model support 5 is the die cast part, identical with general die casting requirement, requires the wall thickness of support 5 housing 6 parts will try one's best evenly, to reduce the casting difficulty, reduces casting flaw to guarantee lower percent defective; For guaranteeing that in the overproof situation of motor stator end size, voltage to earth not occurring punctures, the width of housing 6 can suitably be widened 5 ~ 10mm.
Assembling of the present utility model adopts thermal sleeve stator, and guides lead wire progressively to pass from line outlet, and rotor penetrates from rear end, and because motor is little, lightweight, assembling is moved than being easier to.
But support one-step die casting of the present utility model, the motor assembling is simple, good concentricity, processing is simple, and good looking appearance reduces connecting link, and the equipment joint stiffness is good.Simultaneously the user can also be according to needs are installed, adpting flange in the middle of increasing, and do not worry connecting unreliable, cause equipment running noises and vibration excessive.
