Each mounting flange is coupled to its two adjacent mounting flanges to provide limited movement therebetween.

Description

Fan blade iron is isolated
Technical field
The present invention relates to a kind of fan system that is used to install blade iron and blade, and more particularly, relate to the system that the vibration of the blade that is used to make ceiling fan and drive motor is isolated.
Background technique
Nowadays there are many dissimilar fans, for example ceiling fan, desk fan, stand fan and the fan that uses in conjunction with machinery.Great majority in these fans comprise blade and blade are coupled to the vanes fixed part or the blade iron of motor.
Electronic ceiling fan has usually to be installed in from ceiling board and suspends motor in the set casing that gets off in midair.In operation, motor makes the annular array rotation of the indivedual extensions that are vanes fixed part or blade iron form.Each blade iron is associated with the blade that is installed to it.
Generally be coupled to blade iron by the blade that makes mounting screw pass the hole in the blade and to enter in threaded hole in the blade iron with ceiling fan.Then blade iron is installed to motor.
Ceiling fan transmits the noise that motor causes especially easily, because the area of blade and length are bigger, blade trends towards serving as resonance or sound transmission device, and the noise that therefore trends towards blade is received from drive motor, vibration etc. are delivered to the air.Though drive motor itself comes read fortune to quiet separately, when being used to drive ceiling fan blade, can be by blade with disgusting noise transfer to surrounding environment.Therefore, for example the noisy stator that is caused by loose slightly stator lasmination (it will produce other and not make a nuisance of oneself relatively and unnoticed stator buzz) can transmit sometimes and pass motor configuration, pass blade installation box or rotor, arrival blade itself, and produce disgusting strong noise.Similarly, rotor oscillation or noise and bearing noise may be amplified by blade, and become and make a nuisance of oneself.
So as seen, but still need the ceiling fan system of a kind of limit noise to the transmission of rotation blade.Therefore, this ceiling fan system that provides is provided in the present invention.
Summary of the invention
In a preferred form of the invention, a kind of fan comprises: electric motor; The annular array of blade iron; And ceiling fan blade, it is related with each the blade iron phase in the annular array of blade iron.Each blade iron has at least one mounting hole therein and is positioned the interior elastic washer of described mounting hole.Each blade iron of blade iron array is coupled to two other blade iron of settling relatively of blade iron array.
Description of drawings
Fig. 1 is a perspective view of implementing the ceiling fan of principle of the present invention with preferred form.
Fig. 2 is the perspective view of a part of the ceiling fan of Fig. 1.
Embodiment
Next referring to graphic, show ceiling fan 10, it has the electric motor of showing by not that is wired to power supply 13.Motor 13 comprises bottom mounting plate 14, and it is coupled to rotor, makes rotor in the rotation of the operation period of described motor.Motor bottom mounting plate 14 has the annular array of threaded mounting hole 19.Ceiling fan 10 also comprises the annular array of the blade iron 16 that is coupled to mounting plate 14, and each blade iron has a blade 17 that is installed to it in a usual manner.
Each blade iron 16 has a motor mounting flange 21, and it is configured to bottom mounting plate 14 couplings with motor 13.Each mounting flange 21 has: depressed part or recess 23, and it extends from lower surface 24 and internal surface 25; Terminal tongue-like part 26; And terminal groove part 27, it is configured to admit terminal tongue-like part 26.Terminal groove part 27 comprises alignment pin 28 and threaded mounting hole 29.Terminal tongue-like part 26 comprises: mating holes 30, and it is configured to admit groove part alignment pin 28; And countersink 31, it is aimed at mounting hole 29.Threaded mounting screw 32 passes tongue-like part countersink 31, and is screwed in the groove part mounting hole 29.Thus, each mounting flange 21 is coupled to two to be settled and contiguous mounting flange 21 relatively, and wherein tongue-like part and groove part are provided at restricted movement therebetween.The distance that recess 23 extends from lower surface 24 is less than the total thickness of mounting flange, and therefore stays the relatively thin part 35 of flange.Recess 23 also comprises semicircle aperture or the slit of inwardly opening 38, and it is at throat 39 places of relative narrower blocking-up internal surface 25.Threaded mounting hole 19 aligned in general of slit 38 and bottom mounting plate 14.
The elastomeric isolation member that is rubber washer 40 forms is configured to be received in substantially in the recess 23, and in particular, is supported on the thin part 35 in the slit 38.Packing ring 40 has substantially cube shaped, and possesses and pass its axially extended internal clearance opening 42.The sidewall of packing ring 40 possesses the relative groove of outwards opening 44, makes described groove proportional to admit the part 35 of mounting flange at slit 38 places when being pressed into packing ring in the appropriate location and be fixed in the recess 23.When packing ring by so fixedly the time, the part of packing ring extends in the recess 23 below part 35, but the axial thickness of packing ring 40 makes the described part that extends in the recess be completely contained in the described recess.When inserting packing ring, another part of packing ring 40 extends above the upper surface of mounting flange.Narrower throat 39 trends towards making packing ring to remain on the appropriate location.
Opening 42 in the packing ring is suitable for admitting and is threaded form of taking the lead peg 50, and peg 50 is only threaded in its outer end 52 place's parts.Described screw thread is intended to be received in one in the mounting hole 19 of mounting plate 14.Peg 50 extends in the mounting plate, only arrives the predetermined depth that the degree of depth by screw thread 52 defines, and when peg 50 being inserted when passing packing ring opening 42, and mounting flange 21 hangs on the mounting plate below on the enlarged head 51 of peg 50.Packing ring 40 is directly contacted with mounting plate 14.
Packing ring 40 is provided for making the member of blade iron 16 from motor mount plate 14 suspensions with peg 50, thereby has eliminated metal and Metal Contact.Be coupling in the whole weight of carrying fan blade 17 and blade iron 16 on the peg 50 by the elasticity that defines by packing ring 40.The enlarged head 51 of admitting peg at the contiguous place of the outer surface of packing ring 40, and therefore the weight of blade iron and blade is transferred to the head of peg usually by packing ring 40.Blade iron through connecting fine is free to slide on threaded peg up and down with the packing ring 40 that is pinned.The trickle purpose that moves axially degrees of freedom provides the isolation fully of blade iron and mounting plate 14.
Should be understood that the present invention provides a kind of elasticity attachment that does not have any metal and Metal Contact between blade iron 16 and motor mount plate 14.Any vibration in the motor will trend towards being absorbed in the packing ring 40, thereby make the blade 17 directly effect isolation of transmission vibration therewith effectively.
Should be understood that the present invention is not intended to be limited to ceiling fan, and can be applied to the fan of any kind with being equal to.Should also be understood that the blade or the blade iron that the invention is not restricted to a certain number.
Therefore as seen, provide a kind of ceiling fan now, it isolates motor noise and vibration in the fan.Though describe the present invention in detail with particular reference to the preferred embodiments of the present invention, but should understand, under the situation of the spirit and scope of the present invention that can in not breaking away from, be stated, make many modifications, interpolation and deletion except that modification, interpolation and the deletion of clearly narration as appended claims.
