Abstract
The utility model discloses a screw shaft motor mounting seat structure. The screw shaft motor mounting seat structure comprises a motor seat, a screw shaft, a shaft coupling, a planetary reducer, a first flange and a second flange, wherein the screw shaft is connected with the planetary reducer through the shaft coupling, and is mounted inside the motor seat, the first flange is mounted at one end of the motor seat which is far away from the screw shaft, the second flange is arranged on the motor seat and is used for sleeving an inner end surface of a screw shaft portion, and is fixedly connected with the motor seat, and the motor seat is an integral-casting structure. The screw shaft motor mounting seat structure of the utility model has the following advantages that: 1, the single-casting structure is adopted, and therefore, the rigidity of the screw shaft motor mounting seat structure is improved; 2, a matching hole at one end where the motor seat is connected with the planetary reducer (or motor) is enlarged, which is beneficial to the processing of flange fixing screw-thread holes; 3, with the integral structure adopted, the requirement for the concentricity of the screw shaft ad the planetary reducer (or motor) in assembly can be satisfied; and 4, with the screw shaft motor mounting seat structure adopted, machining and assembly work hours can be shortened, and therefore, work efficiency can be improved.
Description
Technical field
The utility model relates to motor cabinet, is specifically related to a kind of spindle motor mount pad structure.
Background technology
At present, the spindle motor mount pad adopts separate type mostly: be about to motor mount and be divided into two parts, a part connects planetary reduction gear (or direct-connected motor), a part is connected with the bearing mounting flange, its two parts are made up, such structure has reduced the integral rigidity of motor mount, and the time has increased the adjustment difficulty of concentricitys such as leading screw and motor in assembling, and then the stability when having influence on leading screw and move.
Summary of the invention
The problems referred to above at existing spindle motor mount pad exists now provide a kind of more stable mount pad of spindle motor more easily structure.
Concrete technical scheme is as follows:
A kind of spindle motor mount pad structure, it is characterized in that, comprise motor cabinet, leading screw, shaft coupling, planetary reduction gear, first flange and second flange, described leading screw is connected by described shaft coupling with described planetary reduction gear, and be installed in the described motor cabinet, described first flange embeds and is installed on described motor cabinet away from an end of described leading screw, described second flange is arranged at the inner face place that described motor cabinet is used for sheathed described leading screw part, described second flange and described motor cabinet are connected and fixed, and described motor cabinet is the single-casting structure.
Preferably, the mating holes diameter that arranges away from described motor cabinet one end of described leading screw is greater than described second flange outer diameter.
Preferably, described leading screw two ends are arranged with spacer, and the described spacer of described leading screw one end of close described shaft coupling is fixed with described second flange by being threaded.
Preferably, sheathed bearing on the described leading screw at the inboard two ends of described spacer, described spacer tightens described bearing.
Preferably, described leading screw stage casing, overlapping inner spacing collar and the outer separator of being arranged with up and down, described inner spacing collar and described outer separator are fixed between the described bearing.
Preferably, described motor cabinet is connected by screw with described first flange.
The beneficial effect of technique scheme is:
1. whole member adopts the single-casting structure, has improved its rigidity greatly;
2. the spindle motor mount pad is connected an end mating holes with planetary reduction gear (or motor) and enlarges, be conducive to the processing to leading screw bearing ring flange retaining thread hole;
3. adopt monolithic construction to guarantee leading screw and the concentricity requirement of planetary reduction gear (or motor) when assembling;
4. adopt this structure and to reduce greatly during the assembler processing, thereby improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the embodiment of a kind of spindle motor mount pad of the utility model structure.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as restriction of the present utility model.
The embodiment of a kind of spindle motor mount pad of the utility model structure comprises motor cabinet 17, leading screw 1, shaft coupling 10, planetary reduction gear 13, first flange 11 and second flange 7 as shown in Figure 1; Spacer 16 is placed on the leading screw 1, then leading screw 1 is inserted in 17 li of motor cabinets, then successively with bearing 2, inner spacing collar 3, outer separator 4, bearing 2 are placed on the leading screw 1 and mutually and tighten, and second flange 7 is placed in the end that leading screw 1 is positioned at motor cabinet 17, and with high nut 8 and thin nut 9 and spacer 16 chuckings, be screwed into screw 15 and fix; First flange 11 is placed in motor cabinet 17 away from fixing in the mating holes of an end of leading screw 1 and by screw 12 and motor cabinet 17, motor 14 be inserted in first flange 11 after planetary reduction gear 13 connects and be connected with leading screw 1 by shaft coupling 10, by screw 5 end cap 6 is fixed on the motor cabinet 17 at last.
The operation principle of technique scheme is: motor cabinet 17 adopts the single-casting structure, and enlarge the diameter that motor cabinet 17 and first flange 11 go out, make diameter greater than the external diameter of first flange 11, such mounting structure has not only guaranteed processing space and the assembly space of second flange 7, has also improved the rigidity of motor cabinet 17 greatly; Concentricity when monolithic construction has guaranteed leading screw 1 and planetary reduction gear 13 assemblings.
On the technique scheme basis, further, motor cabinet 17 connects the mating holes enlarged-diameter at first flange, 11 places to the external diameter size greater than first flange 11, has guaranteed second flange, 7 needed processing space and assembly spaces like this.
On the technique scheme basis, further, what motor cabinet 17 adopted is the structure of single-casting, and such structure has improved integral rigidity and processing and the assembly process process of motor cabinet greatly, has guaranteed the requirements such as concentricity of leading screw and motor simultaneously.
The above only is the utility model preferred embodiment; be not so limit claim of the present utility model; so the equivalent structure that all utilization the utility model specifications and diagramatic content are made changes, and all is included in the protection range of the present utility model.
