Description

The motor slowing-down structure of circulating fan

Technical field

The utility model provides a kind of technical field of circulating fan, refers to its technical motor slowing-down structure that a kind of circulating fan is provided especially, meshes multiple tooth driven gear to establish hiding few tooth driving gear in its outer shaft-cup, reaches and slows down and high-energy source efficient.

Background technique

Press, the factory of commonly using or than the environment of large space, its large-scale ventilation cycle fan, topmost requirement will avoid excessive vibrations or wind to cut noise exactly, and slow-revving output motor is arranged simultaneously.The motor of traditional slow-speed of revolution output, its as a kind of motor shaft directly output straight junction type and utilize motor shaft the place ahead increase in addition one group of deceleration purposes the time rule belt pulleys the indirect drive type.The motor of this straight junction type is high rotating speed motor as adopting, then because high rotating speed can't meet demand, the manufacturer is essential make special-purpose slow-speed of revolution motor come in response to, but this slow-speed of revolution motor equates on the energy efficiency of rotating speed in output, cause considerable consume and impracticable, also caused a kind of waste of the energy.

Other is the person, utilize increase belt, belt pulley to reach the purpose of deceleration, also cause energy loss in the transmission course of its belt of setting up, pulley decelerates, be contained in the pulley decelerates mechanism at fan rear, cause overall volume to increase, the part that circulating fan will be safeguarded increases.

Be with, at the existing problem points of above-mentioned conventional construction, how to develop a kind of innovation structure that has more desirable practicability, the ardent hope of real Consumer institute also is that relevant dealer must make great efforts target and the direction that research and development break through.

In view of this, the creator this in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicability.

Summary of the invention

The purpose of this utility model is, a kind of motor slowing-down structure of circulating fan is provided, and desires to solve the problems of the technologies described above a little, reaches the effect of deceleration and high-energy source efficient.

The technical characterstic of dealing with problems: a kind of motor slowing-down structure of circulating fan, it is characterized in that, include: a drive motor, one main shaft, driving gear, one outer shaft-cup, one driven spindle and a driven gear, wherein be somebody's turn to do the one-body molded base support of outer shaft-cup, should more be provided with first by outer shaft-cup, two, three ccontaining alcove mutual conduction, should outer shaft-cup substantially horizontal secure to this drive motor, this the first ccontaining alcove that is somebody's turn to do outer shaft-cup provides main shaft and driving gear setting, this second ccontaining alcove is provided with an internal axle sleeve, this second ccontaining alcove cooperates this internal axle sleeve group to be provided with a driven spindle and a driven gear, this driven gear and driving gear engagement, should lack flute profile driving gear and multiple tooth type driven gear in view of the above and reach the interior hiding reduction gears mechanism of outer shaft-cup, reach the effect of low and slow rotating speed driving and high-energy source efficient.

The effect of contrast prior art: the straight junction type of prior art or the motor of indirect drive type, it has motor need make slow-speed of revolution motor, maybe need add thong, belt pulley, take more spaces and volume is bigger, slow-speed of revolution motor and belt, belt pulley all have the problem of energy consume, and this driven gear of the present utility model and driving gear engagement, should lack flute profile driving gear and multiple tooth type driven gear in view of the above and reach the interior hiding reduction gears mechanism of outer shaft-cup, reach the effect of low and slow rotating speed driving and high-energy source efficient.

The technology that relevant the utility model adopted, means and effect thereof after lifting a preferred embodiment now and cooperating graphic being described in more detail in, are believed the above-mentioned purpose of the utility model, structure and feature, when can by one deeply and concrete understanding.

Embodiment

Consult Fig. 1 to shown in Figure 5, the utility model provides a kind of motor slowing-down structure of circulating fan, comprising:

One drive motor 10, these drive motor 10 substantially horizontals run through and convex with a main shaft 11, and the front end of this main shaft 11 is installed with a driving gear 12;

One outer shaft-cup 20, should be provided with one first ccontaining alcove 21, one second ccontaining alcove 22 and one the 3rd ccontaining alcove 23 by outer shaft-cup 20, this first ccontaining alcove 21 and the different direction opening of second and third

ccontaining alcove

22,23 towards level, the inner face of this second ccontaining alcove 22 is formed with an internal axle sleeve 221, this first, second and third

ccontaining alcove

21,22,23 also connects mutually, and this first ccontaining alcove 21 places for main shaft 11 and this driving gear 12; And,

One driven spindle 30, this driven spindle 30 are worn and are organized in the second ccontaining alcove 22 and this internal axle sleeve 221 places, are installed with a driven gear 31 on this driven spindle 30, and this driven gear 31 is meshed with this driving gear 12.

Above-mentioned these outer shaft-cup 20 one-body molded bases 24 make this outer shaft-cup 20 also have the firm support effect by this base 24.

The motor slowing-down structure of above-mentioned this a kind of circulating fan, should outer shaft-cup 20 substantially horizontals secure to this drive motor 10, this the first ccontaining alcove 21 that is somebody's turn to do outer shaft-cup 20 provides main shaft 11 to place, set firmly a driving gear 12 on this main shaft 11, the second ccontaining alcove 22 that is somebody's turn to do outer shaft-cup 20 is provided with an internal axle sleeve 221, this second ccontaining alcove 22 cooperates this internal axle sleeve to be provided with a driven spindle 30 for 221 groups, set firmly a driven gear 31 on this driven spindle 30, this driven gear 31 and driving gear 12 engagements, in view of the above should few flute profile driving gear 12 reach hiding reduction gears mechanism in the outer shaft-cup 20, reach the effect of low and slow rotating speed driving and high-energy source efficient with multiple tooth type driven gear 31.
