Abstract
The utility model discloses a hand wheel for a motor of a direct drive sewing machine. The hand wheel comprises a hand wheel frame, wherein the hand wheel frame is provided with cascading louvers which pass through a plurality of spokes. As the improvement of the utility model, the inner side of the hand wheel frame is provided with a plurality of fan blades integrated with the hand wheel frame. The hand wheel frame is provided with a fan, so that the radiating condition of the motor can be improved effectively; moreover, the fan blades and the hand wheel are molded integrally by injecting, so that processing technique is simplified and processing cost is lowered.
Description
Technical field
The utility model relates to the electrical motor of sewing machine handwheel, especially a kind of handwheel that can dispel the heat.
Background technology
The handwheel of sewing machine direct driving motor, for aluminum embeds the fan-type handwheel, complex structure, the various processing cost of manufacturing process is higher.Because of its heaviness,, shortened the sewing machine service life of a machine Gu cause sewing machine shake and noise easily.
Summary of the invention
The utility model is for solving prior art in use, and the overedger main shaft diameter of existence influences the problem of machine works to walking about, a kind of axle sleeve that can lock the overedger main shaft is provided.
The technical scheme that the utility model solves existing issue is: a kind of electrical motor of sewing machine handwheel that directly drives, comprise the handwheel framework, described handwheel framework is provided with by some spoke serial connection louvers, as improvement of the present utility model, handwheel framework inboard is provided with the fan blade of handwheel framework one some.
As further improvement of the utility model, described handwheel core is embedded with the metal axle sleeve that matches with motor shaft.
As further improvement of the utility model, the described fan blade that is arranged at handwheel framework inboard is that one is injection molded.
As further improvement of the utility model, described handwheel core is embedded with the metal axle sleeve that matches with motor shaft.
The utility model compared with prior art, it can effectively improve the heat radiation situation of motor by will on the handwheel framework fan being set, fan blade and handwheel framework one are injection molded in addition, simplified processing process cuts down finished cost.
Description of drawings
Fig. 1 is a shaft side figure of the present utility model.
Fig. 2 is the axonometric drawing of the utility model other direction.
Embodiment
Referring to Fig. 1-2, the implementation case comprises: handwheel framework 1, handwheel framework 1 are provided with by some spoke serial connection louvers, and handwheel framework 1 inboard is provided with handwheel and the injection molded fan blade 2 of handwheel framework 1 one, fan blade 2 is made as six, is distributed in the handwheel framework 1.Handwheel core 3 is embedded with the metal axle sleeve 4 that matches with motor shaft in addition, and metal axle sleeve 4 also is provided with pin key with handwheel core 3, to strengthen bonding strength; Metal axle sleeve 4 increases the intensity of handwheel, increases the service life.
