Abstract
The utility model provides a casing-less motor of a sewing machine direct drive structure and belongs to the technical field of motors. The motor solves the problem that the existing direct drive structure is not easy to assemble, low in concentricity, not impact in structure and the like. The casing-less motor comprises a motor stator and a rotor. An axial fixed hole is formed in the motor stator, a bolt penetrates the fixed hole to fix the motor stator on a sewing machine casing, and an axial hole for inserting and fixing a sewing machine spindle is formed in the middle of the rotor. The casing-less motor has the advantages of removing a coupler, improving the concentricity, removing parts such as a motor casing, an end cover and a bearing, reducing cost, being compact in integral structure, reducing occupation space and the like.
Description
Technical field
The utility model belongs to technical field of motors, refers in particular to a kind of Sewing machines and directly drives the shellless motor of structure.
Background technology
Traditional Sewing machines drives structure is to adopt motor, belt and belt pulley transmission machine spindle, this kind of structure is eliminated gradually, adopt the novel structure of directly driving to be: motor and machine spindle to be coaxially set, motor shaft to be connected with machine spindle with shaft coupling, directly drive the appearance of structure, with respect to the transmission of belt belt pulley, played the loss that reduces power, transmission is more accurate, with respect to its clutch structure, directly drive stop accurately, pin number effectively controls, advantage is apparent.
At present, the existing ubiquitous defect of structure of directly driving is: the one, the inconvenience of installing, motor entirety is cumbersome with the operation of Sewing machines assembling, in view of the weight of motor entirety heavier, the coaxial line that also needs to ensure motor shaft and sewing arbor, there is certain difficulty in this assembly manipulation; The 2nd, the reduction of concentricity, above-mentioned assembling process has certain reduction concentricity to be affected, and also has certain reduction impact because adopting shaft coupling to connect diaxon simultaneously, and the 3rd, the overall required certain space that takies of motor, sewing machine structure property compact to design reduces.
Summary of the invention
The purpose of this utility model is to provide a kind of Sewing machines and directly drives the shellless motor of structure, it has solved the above-mentioned ubiquitous defect of structure of directly driving, motor integral installation is become successively each parts are mounted on Sewing machines, overcome thus the difficulty of assembling, and removed shaft coupling, the arbor that makes to sew is motor shaft, overcome the problem that concentricity reduces, next does not have electric machine casing, has simplified the structure, has reduced production cost and reduced shared space yet.
The purpose of this utility model is achieved in that
Sewing machines directly drives the shellless motor of structure, comprise motor stator and rotor, it is characterized in that: on described motor stator, offer axial fixing hole, bolt is fixed on motor stator on sewing machine case through fixing hole, the middle part of rotor is provided with the axis hole of the fixing machine spindle of pegging graft.
Directly drive in the shellless motor of structure at above-mentioned Sewing machines, on the axis hole of described rotor, be provided with the axle sleeve of fixing machine spindle, on the iron core of rotor, be evenly equipped with several magnetic shoes.
Directly drive in the shellless motor of structure at above-mentioned Sewing machines, described motor stator is to form by multi-disc stator punching is bonding, and described stator punching is rectangular or circular, the fixing hole on four angles of stator punching or described in offering in outer side edges.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the motor shaft in the utility model is machine spindle, and machine spindle is plugged in rotor fixing, does not have thus concentricity phenomenon devious, has removed these parts of shaft coupling, has lowered cost than the existing concentricity that promoted simultaneously.
2, the stator in the utility model is directly fixed with Sewing machines housing, and in installation procedure, the structure substep installations such as stator, rotor, have removed the parts such as electric machine casing, end cap, bearing time easy to assembly, lowered cost.
3, the area of stator punching of the present utility model is increased, and the obtainable electromagnetic quantities of stator punching has obtained enhancing.
4, the volume of entirety of the present utility model reduces, and has dwindled taking up room of Sewing machines entirety, space is provided also to Sewing machines remaining part simultaneously.
5, the utility model has reduced the parts such as shaft coupling, electric machine casing, electric motor end cap, bearing, has simplified electric machine structure, has reduced production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front schematic view of the present utility model.
Fig. 3 is the structural representation of stator punching of the present utility model.
Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:
Sewing machines directly drives the shellless motor of structure, comprise motor stator 1 and rotor 2, it is characterized in that: on described motor stator, offer axial fixing hole 3, bolt is fixed on motor stator on sewing machine case through fixing hole, the middle part of rotor is provided with the axis hole of the fixing machine spindle of pegging graft.
The installation procedure of said structure is: stator is fixed by bolt and sewing machine case, rotor is enclosed within on machine spindle, and axle sleeve 4 and machine spindle are fixed, can adopt alignment pin, bolt etc. radially to tighten fixed form, finally at motor rear end, remaining part is installed.
The axle sleeve 4 that is provided with fixing machine spindle on the axis hole of described rotor, is evenly equipped with several magnetic shoes 6 on the iron core 5 of rotor.
Described motor stator is to form by multi-disc stator punching 7 is bonding, and described stator punching is rectangular or circular, the fixing hole 3 on four angles of stator punching or described in offering in outer side edges.
In the inner circle of stator punching, offer winding slot, the fixing hole 3 of circular stator punching is located on the lamellar body between inner circle and cylindrical.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
