Description
Technical field
The utility model relates to a kind of electric fans, and in particular to a kind of planet carrier connect with ring gear rate controlling fan in winnowing machine
Between ceiling 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.
