Abstract
The utility model discloses a sewing machine motor flywheel. The flywheel comprises a wheel body, a shaft hole wheel hub and fan blades. The wheel body is an iron plate whose central section is arched. The shaft hole wheel hub is fixed on the center of the wheel body. The fan blades are arranged on a plastic sleeve. The plastic sleeve is fixed on one side surface of the wheel body. The plastic sleeve is provided with a through hole which the shaft hole wheel hub passes through. The flywheel possesses the advantages that cost is low; environmental protection is achieved; usage is reliable.
Description
Technical field
Utility model relates to a kind of motor flywheels, particularly a kind of electrical motor of sewing machine flywheel.
Background technology
Existing electrical motor of sewing machine flywheel mainly consists of wheel body, axis hole wheel hub and fan blade, described by wheel body, axis hole wheel hub and fan blade one by the moulding of hot working integrally casting, axis hole wheel hub is fixed on wheel body central authorities, and fan blade is fixed on wheel body one side surface, and centered by axis hole wheel hub annular distribution.The material of the wheel body of above-mentioned flywheel, axis hole wheel hub and fan blade mostly is cast iron, and production process is complicated, the high and contaminated environment of production cost.
Summary of the invention
For overcoming the problem of above-mentioned existence, the purpose of this utility model is to provide that a kind of cost is low, environmental protection, service-strong electrical motor of sewing machine flywheel.
The utility model is to realize like this above-mentioned purpose:
Electrical motor of sewing machine flywheel, comprises wheel body, axis hole wheel hub and fan blade, and described wheel body is the iron plate of arching upward in middle part, axis hole wheel hub is fixed on wheel body central authorities, described fan blade is located on plastic sheath, and plastic sheath is fixed on wheel body one side surface, and plastic sheath is provided with the through hole that allows axis hole wheel hub pass.
Wherein, described wheel body is by iron plate punch forming, and the iron plate of arching upward is provided with several equally distributed holes, and the middle part of plastic sheath is provided with the hemispherical protuberance matching with iron plate arched part.
Wherein, described fan blade is mainly positioned on the hemispherical protuberance of plastic sheath, and one-body molded with plastic sheath, along plastic sheath center annular distribution.
Wherein, the surrounding of described wheel body is provided with flange, forms groove, and plastic sheath is fixed on groove.
Wherein, described wheel body and plastic sheath are provided with the connecting hole cooperatively interacting, and both connect by screw or screw.
The beneficial effects of the utility model are: the iron plate that wheel body of the present utility model is mainly arched upward by middle part forms, and its manufacturing process does not need hot working, only need by the punch forming of iron iron just so just can reduce production stage, cost-saving.Meanwhile, because fan blade is located on plastic sheath, plastic sheath is fixed on wheel body one side surface, plastic sheath is provided with the through hole that allows axis hole wheel hub pass, such design can reduce the raw material use amount of metal material, further saves production cost, and can reach again running inertia force and the radiating effect of equal motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the structural representation of the utility model the first;
Fig. 2 is that the utility model removes the structural representation after plastic sheath;
Fig. 3 is the structural representation of the utility model plastic sheath.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, electrical motor of sewing machine flywheel, comprise wheel body 1, axis hole wheel hub 2 and fan blade 3, the iron plate that described wheel body 1 arches upward for middle part, axis hole wheel hub 2 is fixed on wheel body 1 central authorities, described fan blade 3 is located on plastic sheath 5, and plastic sheath 5 is fixed on wheel body 1 one side surfaces, and plastic sheath 5 is provided with the through hole 6 that allows axis hole wheel hub 2 pass.The iron plate that wheel body of the present utility model is mainly arched upward by middle part forms, and its manufacturing process does not need hot working, only need by the punch forming of iron iron just so just can reduce production stage, cost-saving.Meanwhile, because fan blade is located on plastic sheath, plastic sheath is fixed on wheel body one side surface, plastic sheath is provided with the through hole that allows axis hole wheel hub pass, such design can reduce the raw material use amount of metal material, further saves production cost, and can reach again running inertia force and the radiating effect of equal motor.Wherein, axis hole wheel hub 2 is fixed by welding in wheel body 1 central authorities.
Wherein, described wheel body 1 is by iron plate punch forming, and the iron plate of arching upward is provided with several equally distributed holes 4, adopts above-mentioned hollow structure, and its quality is just concentrated in wheel body 1 outside, and the inertia force in the time of so both can having guaranteed flywheel running, can alleviate its quality again; In addition, the middle part of plastic sheath 5 is provided with the hemispherical protuberance 7 matching with iron plate arched part, and such design can prevent flywheel vibration, guarantees that flywheel rotates more reposefully and has enough running inertia force.
Wherein, described fan blade 3 is mainly positioned on the hemispherical protuberance 7 of plastic sheath 5, and one-body molded with plastic sheath 5, along plastic sheath center annular distribution.Such design can further save production cost, and can further improve again radiating effect.
Also have, the surrounding of described wheel body 1 is provided with flange 8, forms groove, and plastic sheath 5 is fixed on groove, can increase like this quality of wheel body periphery, further improves the running inertia force of flywheel, guarantees that plastic sheath 5 is firmly connected with wheel body 1.
In addition, described wheel body 1 is provided with plastic sheath 5 connecting hole 9 cooperatively interacting, and both connect by screw or screw.While changing wheel body 1 or plastic sheath 5, turn on screw or screw just, facilitate installation and removal.
Certainly; plastic sheath 5 can be glued on wheel body 1; or by 1 welding of iron hoop and wheel body by plastic sheath 5 fixedly on wheel body 1, but the utility model is not limited to the above embodiments, is equal to or becomes bad technical scheme also to belong to protection range of the present utility model with the utility model.
