The technical scheme that the utility model solves the problems of the technologies described above is, provides a kind of servomotor dedicated brake, it is characterized in that: comprise the installation end cap and stator casing portion that are cast into one, and described installation end cap is wrapped in the outside in stator casing portion; The first end of described installation end cap have mate with motor stator first assemble seam, and the size of the periphery of this installation end cap is mated with the size of the periphery of the stator of servomotor.
In servomotor dedicated brake described in the utility model, the second end of described installation end cap have mate with encoder bonnet second assemble seam.
In servomotor dedicated brake described in the utility model, described installation end cap is provided with bearing chamber, and this bearing chamber is positioned at the second end of installation end cap.
In servomotor dedicated brake described in the utility model, described installation end cap is provided with multiple counterbore being evenly distributed on same circumference.
In servomotor dedicated brake described in the utility model, in described stator casing portion, be equiped with brake assemblies.
The utility model also provides a kind of servomotor, comprises rotor, motor stator and brake, and described brake comprises the installation end cap and stator casing portion that are cast into one, and described installation end cap is wrapped in the outside in stator casing portion; The first end of described installation end cap has the first assembling seam, and to be matched with motor stator by this first assembling seam and install; The size of periphery of described installation end cap is mated with the size of the periphery of motor stator.
In servomotor described in the utility model, described servomotor also comprises encoder, and the second end of described installation end cap has the second assembling seam, and this installation end cap is matched with encoder bonnet by this second assembling seam.
In servomotor described in the utility model, described installation end cap is provided with bearing chamber, and this bearing chamber is positioned at the second end of installation end cap.
In servomotor described in the utility model, described installation end cap is provided with multiple counterbore being evenly distributed on same circumference, and described installation end cap is by being bolted to motor stator through described counterbore.
In servomotor described in the utility model, in described stator casing portion, be equiped with brake assemblies.
Servomotor dedicated brake of the present utility model and servomotor have following beneficial effect: by the installation end cap of brake and stator casing portion being cast into one, not only assembly process can be reduced, and can avoid making to be screwed, improve the assembly precision of brake.Further, due to brake stator casing portion and installation end cap compact siro spinning technology, increase brake inside space, thus be conducive to increasing braking moment.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, 2, be the schematic diagram of the utility model servomotor dedicated brake embodiment.This servomotor dedicated brake comprises the installation end cap 11 and stator casing portion 12 that are cast into one, and installation end cap 11 is wrapped in the outside in stator casing portion 12.The first end of above-mentioned installation end cap 11 have mate with motor stator first assemble seam 111, and the size of the periphery of this installation end cap 11 is mated with the size of the periphery of the stator of servomotor.
Brake and installation end cover structure unite two into one by above-mentioned servomotor dedicated brake, can reduce the installation procedure of brake, and reliability high (brake fixed by the screw poor without the need to installation reliability).In addition, due to stator casing portion 12 and installation end cap 11 compact siro spinning technology, can greatly increase brake inside space, thus increase braking moment.
For installation end cap 11 and motor stator being fixed, can arrange multiple counterbore 114 on installation end cap 11, the plurality of counterbore 114 is evenly distributed on circumferentially same.By the bolt through above-mentioned counterbore, installation end cap 11 and motor stator are fixedly mounted.
At the second end of installation end cap 11, also can have mate with encoder bonnet second assemble seam 112, thus realize the installation of encoder.
For realizing the installation of rotor, above-mentioned installation end cap 11 also can be provided with bearing chamber 113, to realize the assembling of bearing.Above-mentioned bearing chamber 113 can be positioned at the one end at the second assembling seam 112 place of installation end cap 11, i.e. the second end of installation end cap 11.
In above-mentioned stator casing portion 12, brake assemblies can be equiped with.These brake assemblies are for realizing the braking of rotor.
Above-mentioned servomotor dedicated brake directly can be assembled to servomotor, now this servomotor comprises rotor, motor stator and brake, wherein: brake comprises the installation end cap and stator casing portion that are cast into one, and installation end cap is wrapped in the outside in stator casing portion; The first end of installation end cap has the first assembling seam, and to be matched with motor stator by this first assembling seam and install; The size of the periphery of installation end cap is mated with the size of the periphery of motor stator.
Also be equiped with encoder in above-mentioned servomotor, and have the second assembling seam at the second end of installation end cap, this installation end cap to be matched with encoder bonnet by this second assembling seam and installs.The installation end cap of above-mentioned servomotor is provided with bearing chamber, and to realize the assembling of rotor, and this bearing chamber is positioned at the second end of installation end cap.
Above-mentioned installation end cap is provided with multiple counterbore being evenly distributed on same circumference, thus installation end cap is by being bolted to motor stator through counterbore.Brake assemblies is equiped with, to brake the rotor through this stator casing in stator casing portion.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
