Description

Fan drive

Technical field

The utility model relates to a kind of fan drive.

Background technique

As shown in Figure 1, known fan driving mechanism 1 is to be provided with a fan page or leaf 11 in center wherein, and be provided with a motor 13 in lateral margin, after this fan page or leaf 11 and motor 13 axles 131 centre respectively are arranged with corresponding drive wheel 12, a sheathed again scrolling belt 14, nationality make fan page or leaf 11 rotate it by the moving belt 14 of 13 drive armies;

General scrolling belt 14 is constituted by the material with toughness; can be to form with motor 13 axles 131 and 12 effects that closely coat (seeing also shown in Figure 2) of drive wheel; when motor turns round for a long time; the outer surface tension that this scrolling belt 14 regular meetings transmission is produced; and the tightness of this scrolling belt 14 is become slack, so often cause drive motor 13 to produce the phenomenon of transmission idle running.Even the awkward situation that causes scrolling belt 14 to break away from, though therefore or can respectively be provided with baffle ring 15 in drive wheel 12 both sides, to limit the Side movement of this scrolling belt 14, be subject to that motor 13 drives and the phenomenon that fluffs and reduce it, but it is still very limited that the effect that is reached so is set, commonly use causing anxiety of getting loose and still can't thoroughly eradicate, by being denounced by the user.

Commonly use disappearance:

1, easily produces the phenomenon of transmission idle running because of elastic fatique.

2, coefficient of losses is higher.

3, often cause belt and belt pulley friction-produced noise because of belt slack.

4, do not have practicability.

5, lack industrial utilization.

Therefore, how above-mentioned disappearance is forgone, be the place of the technical difficulties of this case creator institute desire solution.

One motor is positioned a side of above-mentioned fixing piece one supporting frame, and convexes with an axle in centre;

One fan page or leaf, its central authorities have a positioning hole, and the opposite side axostylus axostyle at the corresponding ventilated port with fixed block of this positioning hole place mutually combines;

One transmission arbor wheel, its both sides respectively have axle center ring, and this connecting part has a joining hole, is sheathed on the axle of said motor, and support ring in its bi-side to being provided with to end;

One taken turns by moving axis, and its central authorities have a connecting part, and this connecting part has the pivot hole that is arranged with the above-mentioned fixing piece axostylus axostyle;

One drivign belt is sleeved on above-mentioned transmission arbor wheel and is subjected to moving axis wheel outer rim;

It is characterized in that: transmission arbor wheel and be subjected to be provided with the staggered corresponding flank of tooth and fin face mutually between moving axis wheel and drivign belt.

In the transmission arbor wheel and be subjected to the flank of tooth of moving axis wheel and the flank of tooth between the groove of ccontaining fin face is arranged.

One in the transmission arbor wheel has only installed a sensitive switch to the ring lateral margin, and sensitive switch electrically is connected in a display unit.

Sensitive switch is in ending to the mating face of encircling a little more than drivign belt.

The advantage that the utlity model has:

1, can reach the effect that is difficult for getting loose.

2, can obtain preferable transmission effect.

3, can make fan transmission and motor running synchronous, and make transmission efficiency can level off to 100%.

4, belt width is bigger, and the transmission arbor wheel is promoted greatly with being subjected to moving axis spacing stability when turning round.

5, can not produce friction and noise in the time of can guaranteeing to turn round between belt and belt pulley.

6, has Security.

7, has practicability.

8, has industrial utilization.

9, meet ergonomics.

Embodiment

The present invention is described in further detail below in conjunction with drawings and the specific embodiments.

Shown in Fig. 3,4, the utility model fan drive mainly comprises: a casing 2, and its inside forms a containing space 21, and forms a containing space 21 in the back side, and forms a ventilated port 22 in the back side;

One fixed block 3, its central authorities have a driving component 31, are penetrated with axostylus axostyles 32 in the driving component 31 towards both sides, and in around form number supporting frame 33, nationality is to be positioned the containing space 21 of casing 2 inside;

One motor 4 is sides that are positioned fixed block 3 one supporting frames 33, and convexes with an axle 41 in centre;

One fan page or leaf 8, its central authorities have a positioning hole 81, and this positioning hole 81 is to mutually combine with the axostylus axostyle 32 at fixed block 3 corresponding ventilated ports 22 places, makes it to form interlock with axostylus axostyle 32;

One transmission arbor wheel 5, its both sides respectively have axle center ring 51, and this connecting part 51 has a joining hole 52, nationality is to be sheathed on motor 4 axles 41, and support ring 55 in its bi-side to establishing to end, nationality produces the chance that friction gets loose to place restrictions on the Side movement of above-mentioned drivign belt 7 to reduce it;
