Abstract
The invention relates to a bearing supporting device of stepping motor. The bearing supporting device includes: an upper bearing supporting the shaft; an injection molding object, wherein the inboard part of the injection molding object supports the upper bearing, the upper part of the injection molding object is integrated with an upper fixed part, the upper fixed part can fix the motor on the required attachment; a chassis, wherein the chassis is provided on the surrounding of the motor external surface, the lower end of the upper fixed part of the injection molding object is fixed on the upper part of the chassis; a lower bearing for supporting the lower part of the shaft; and a support injection molding object supporting the lower bearing.
Description
Technical field
The present invention is about the bearing support assembly of stepping motor, is specially the bearing support assembly about the stepping motor that upper bearing (metal) and lower bearing is supported by injection molding object.
Background technology
The bearing support assembly of traditional stepping motor as shown in Figure 1, the upper bearing (metal) 12 that axle 10 is supported is by the end portion supports of injection molding object 14, the upper fixed of injection molding object 14 upper flange 20, motor can be fixed to required being attached on the thing (not diagram).The external surface peripheral of motor is provided with cabinet 26, cabinet 26 upper bend, and crooked position is in the below of upper flange 20.Injection molding object 14 is wound with coil 30 in the space open towards cabinet 26 directions, be provided with external member 32 in an opposite side, is provided with magnet 46 in the position relative with external member 32, and magnet 46 is supported by magnet support portion 48.The below of axle 10 is supported by lower bearing 42, and the lower flange 40 that lower bearing 42 is made by iron plate supports.
Above-mentioned traditional structure, because the upper bend of cabinet 26, not only cabinet 26 is not easy processing, also can increase motor weight.
In addition, lower flange 40 is made by iron plate, makes lower bearing 42 shapes become big, weight and increases the weight of, thereby increase motor weight.
Summary of the invention
The present invention proposes for addressing the above problem, the present invention seeks to, a kind of bearing support assembly of novel stepper motor is provided, and this device alleviates motor weight by eliminating the upper bend portion of cabinet, by injection molding object upper bearing (metal) and lower bearing are supported, simplify the bearing shape, need not additionally to be provided with upper flange, can be integrally manufactured with injection molding object, thereby not only can alleviate motor weight, can also simplify manufacture process.
The bearing support assembly of stepping motor of the present invention, this bearing support assembly comprises: the upper bearing (metal) that axle is supported; Injection molding object, this injection molding object supports upper bearing (metal) with the inside portion, and the top of described injection molding object is formed with fixed part, and fixed part can be fixed on motor required being attached on the thing on this; Cabinet, this cabinet is arranged on the motor external surface peripheral, and the top of this cabinet is fixed on the lower end of the last fixed part of injection molding object; The lower bearing that the below of axle is supported; Support the support injection molding object of lower bearing.
Described cabinet is rolled into cylindrical shape by the sheet material that cuts and makes, or is formed by the cylindrical duct cutting.
The bearing support assembly of stepping motor of the present invention can be simplified the cabinet shape, uses light sheet to process, and can directly support bearing by injection molding object, motor can also be fixed on to be attached on the thing, thereby alleviate motor weight.

Embodiment
Below in conjunction with accompanying drawing embodiments of the present invention are elaborated.
As shown in Figure 2, the upper bearing (metal) 112 that axle 100 is supported is supported by the inside portion 122 of injection molding object 120, and the top of injection molding object 120 is formed with fixed part 121, motor can be fixed on required being attached on the thing (not diagram).The external surface peripheral of motor is provided with cabinet 126, and the top of cabinet 126 is fixed on the lower end of the last fixed part 121 of injection molding object 120, compares traditional structure, can not form upper bend portion.Injection molding object 120 is wound with coil 130 in the space open towards cabinet 126 directions, be provided with external member 132 in an opposite side, and the position relative with external member 132 is provided with magnet 146, and magnet 146 is supported by magnet support portion 148.The below of axle 100 is supported by lower bearing 142, and lower bearing 142 supports by supporting injection molding object 140.
Fig. 3 and Fig. 4 are the oblique views of cabinet 126, and cabinet 126 is rolled into cylindrical shape by the sheet material that cuts and makes, or are formed by the cylindrical duct cutting.
Fig. 5 and Fig. 6 are the shape schematic diagrames of going up fixed part 121, are formed with a plurality of link slots.
Above-mentioned explanation only is the preferred implementation of the bearing support assembly of stepping motor of the present invention, the present invention is not limited thereto, in the scope that does not break away from the described main idea of the present invention of claims, domain background is known the knowledgeable under having the present invention, can carry out numerous variations, these all should belong to claim scope of the present invention.
