Structure such as is repaired, changed and adjusted at the operation.
Buckle is provided with the driving lid 1, neck is provided with the driving drain pan 2.
The transmission mechanism includes drive gear 5 and driven gear 6, the drive gear 5 and the phase of power mounting hole 3
Coordinate, the driven gear 6 is engaged with the load mounting hole 4, and is meshed with the drive gear 5, the sliding tooth
Wheel 5 is engaged with the drive shaft of the drive mechanism, in general, and gear is respectively provided with the drive shaft of the drive mechanism (such as electricity
Machine), the drive gear 5 can be meshed with the gear, and the driven gear 6 is engaged with load installation axle, completes transmission.
The drive mechanism also includes the support shaft 7 being arranged in the driving box, be provided with the driven gear 6 with
The endoporus of driven gear 6 of the coaxial line of driven gear 6, the driven gear 6 are arranged at institute by the endoporus of driven gear 6
State in support shaft 7, and can freely be rotated along the axis of the support shaft 7 in the support shaft 7, traditional design, load peace
Dress is installed together on the inside of end with motor output shaft, and due to loading self gravitation reason, motor output shaft can undertake support load
Self gravitation, now motor shaft undertakes an eccentric force, and this power is bigger with loading, and eccentric force is bigger；Particularly
When motor internal also has other drive mechanisms, being deflected when motor internal drive mechanism can be caused to run, concentrated wear is accelerated,
Gear face temperature raises, and causes lubrication failure to be accelerated, and then cause integrated motor rapid failure.Other traditional structure is due to negative
It is loaded in motion process, in diverse location, torque of the practical function on motor is constantly in change, extremely uneven
Surely, fluctuate especially big.Due to motor, partly or wholly internal gear fails, and operation control sweeps wind angle and is just unable to reach expected set
Count effect, be related to air-conditioning equipment, because wind-guiding is abnormal, cause air supplying distance to decline, comfortableness and then decline, when wherein have from
During moving gear 6, the driven gear 6 itself has certain gravity, and in transmission process is carried out, can produce eccentric load
Lotus, when using support shaft 7, above-mentioned gravity and eccentric load can all be undertaken by support shaft 7, reduce driving
Power suffered by mechanism, the service life of drive mechanism is added, also ensure that the biography of drive mechanism provided by the utility model
Dynamic precision and reliability.
The driven gear 6 includes gear part 61 and is arranged at the driving section 62 of described one end of gear part 61, the gear
Portion 61 is arranged in the driving box, and is meshed with the drive gear 5, the cross section of the driving section 62 be it is non-circular,
And the driving section 62 is stretched into the part stretched into the load mounting hole 4 with load in the load mounting hole 4 and is engaged, one
As, the external diameter for loading installation axle is smooth cylindrical structural, and it is non-circular fixation that cross section is provided with its axis
Hole, the driving section 62 can reach the purpose transferred a torque at load in the deep enough non-circular fixing hole.
Preferably, the driven gear endoporus runs through the gear part 61 and the driving section 62.
There is the first gap 11, institute between the part that the load mounting hole 4 and load are stretched into the load mounting hole 4
Stating between the outer wall of driving section 62 and the endoporus for loading the part stretched into the load mounting hole 4 has the second gap
12, there is third space 13, second gap between the outer wall of the support shaft 7 and the inwall of the endoporus of the driven gear 6
12 are more than the third space 13 more than first gap 11 and second gap 12, and above three gap is required to protecting
Demonstrate,proving driving supporting mechanism provided by the utility model can produce and compare on the premise of normal work, wherein, it is described
Form first gap 11 between load mounting hole 4 and the load installation axle, the outer wall of the driving section 62 with it is described solid
Determine to form second gap 12 between hole, because load self gravitation part can act directly on load mounting hole due to gravity
On 4 inwall, so needing second gap 12 to be more than first gap 11；In order to ensure the energy of one side driven gear 6
Precise rotation is kept in support shaft 7, rational design fit clearance can be reached when being driven with drive gear 5, on the other hand, is ensured
Driven gear 6 by load self gravitation or is not solely subjected to minimum gravity, and therefore, second gap 12 is more than between described first
Gap 11.
Preferably, second gap 12 is more than the third space 13 more than first gap 11.
The load mounting hole 4 extends to form driving drain pan support level 8, the driving drain pan to the direction towards load
The part that support level 8 is stretched into the load mounting hole 4 with load forms first gap 11.
The external diameter that the internal diameter of i.e. described driving drain pan support level 8 is more than the load installation axle is more than the driven gear
The diameter of 6 endoporus is more than the diameter of the support shaft 7.
Preferably, ensureing that drive mechanism provided by the utility model can be on the premise of normal work, between described first
The scope of gap 11 is 0.05-0.1mm；The scope in second gap 12 is 0.1-0.15mm；The scope of the third space 13
For 0-0.04mm.
The driving drain pan 2 is made up of high-abrasive material；The support shaft 7 is made up of high-abrasive material；The driven gear 6 by
High-abrasive material is made because above-mentioned three is also easy to produce friction, when using high-abrasive material when, can ensure transmission reliability and
Service life.
The driven gear 6 driving force required when operating is with regard to smaller, because due to the driving drain pan support level 8
Bearing part gravity, therefore torsion is just reduced caused by gravity；Gap is small between driven gear 6 and support shaft 7 in addition, driven tooth
In driving load, produce eccentric load also can further act directly in support shaft 7 wheel 6, due to support shaft 7 and driven tooth
Wheel 6 is made using High Strength Wear-Resistance Material, and reliability is further strengthened, and part eccentric load acts on support shaft 7
On, then on drive gear 5 is transmitted to, and on motor output shaft, the load force at this moment acted on motor is relatively conventional
For structure, substantially reduce, and born to load that relative fluctuation is smaller, and motor shaft or internal gear can obtain more steady
Operation, ensure that operating is reliable, motor internal tooth foot wheel abrasion is reduced, and sweeping wind angle control precision can preferably be controlled.And then it can grow
Time ensures that sweep wind energy is carried out by expected design angle, and Consumer's Experience can reach requirement
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
