Description
Technical field
The present invention relates to a kind of electric fans, and in particular to hangs in a kind of connect with the ring gear fan middle fan workshop of rate controlling of planet carrier
Fan.
Background technique
Currently, there are many type of common electric fan, power is small, revolving speed is fast, is widely used in family, office, hotel, hospital
And the places such as school, it should not be used in large scale industry workshop, especially big machinery workshop.Due to production need and
The limitation of operating condition, big machinery workshop space is big, airtightness is poor, should not install air-conditioning, and common electric fan is difficult to fit
Answer putting for varying environment, and the purpose of the small pectinid driving away summer heat for being unable to satisfy large space of wind-force.
To solve the above-mentioned problems, existing some enterprises design and have manufactured large-scale ceiling fan, produce vehicle for large scale industry
Between, the mentality of designing of these large-scale ceiling fans is also limited to the mode of a set of fan main body, and fan blade diameter is generally 5~8m, even
Up to 10m, rated power is big, and pectinid range is wide, while also solving the problems, such as to put hardly possible due to varying environment.But by
It is big in fan blade diameter, rated speed is limited, because of u=r ω, wherein fan blade radius r is big, it is necessary to angular velocity omega is reduced, it is no
Then the outer peripheral linear velocity u of fan blade is excessive, and linear velocity is bigger, and centrifugal force is bigger, and it is bigger to will lead to stress, more dangerous, so
Rated speed is generally limited to 50~100r/min.The aggregation of wind direction circle center opposite direction, remoter from circle center, linear velocity is got over
Greatly, wind is assembled more；Conversely, closer from circle center, linear velocity is smaller, and wind is assembled fewer.Existing large size ceiling fan is all deposited
It remotely can achieve required wind-force from center of rotation, from center of rotation more nearby wind-force very little.In addition, fan blade length
Long, processing difficulties, to material requirements height, manufacturing cost is high.
Summary of the invention
In view of the deficienciess of the prior art, the invention reside in the fan for providing a kind of planet carrier with ring gear and connecting rate controlling
Ceiling fan between winnowing machine has broken the traditional mode of an a set of fan main body of ceiling fan, is provided with two sets of fan main bodies, wherein a set of wind
Several fan blades of fan main body are annularly distributed the outside that several fan blades of another set of fan main body are arranged in, and fan blade is located at outside
Fan main body is slowed down by planetary gear train, and the fan main body that fan blade is located at inner edge is increased by differential gear train again after being slowed down by planetary gear train
Speed has obtained two different revolving speeds, forms fan middle fan.External wind wheel revolving speed is slow, and interior fan blade revolving speed is fast, solves from rotation
The heart more nearby wind-force very little the shortcomings that；It is made of intra vane and outer leafs instead of original a piece of linear leaf, shortens blade
Length, improve processing technology, reduce material requirements, reduce manufacturing cost.
To achieve the above object, the present invention provides the following technical scheme that including driving mechanism, retarder and fan master
The top of retarder is arranged in body, the driving mechanism, and the lower section of retarder is arranged in the fan main body, and described subtracts
