Abstract

The invention discloses a fan-in-fan workshop ceiling fan adopting double-row planetary gear train deceleration. The fan-in-fan workshop ceiling fan comprises a driving mechanism, a speed reducer anda fan main body. The driving mechanism comprises a motor and an input shaft. The speed reducer comprises an upper-row planetary gear train and a lower-row planetary gear train. The upper-row planet gear train comprises an upper sun gear, an upper planet gear, an upper planet carrier and an upper inner gear ring. The lower-row planetary gear train comprises a lower sun gear, a lower planetary gear,a lower planet carrier and a lower inner gear ring. The upper planet carrier is connected with the lower sun wheel. The upper inner gear ring and the lower inner gear ring are fixed. The fan main body comprises a first fan main body and a second fan main body. The first fan main body is connected with the upper planet carrier. The second fan main body is connected with the lower planet carrier. One end of the input shaft is connected with the motor, and the other end of the input shaft is connected with the upper sun wheel. By adopting the structure, the rotation speed of the first fan body can be larger than that of the second fan body, so that the fan-in-fan purpose is realized.

Description

technical field [0001] The invention relates to an electric fan, in particular to a fan-in-fan workshop ceiling fan with double-row planetary gear train deceleration. Background technique [0002] At present, there are many types of ordinary electric fans, with low power and fast speed, and are widely used in places such as homes, offices, hotels, hospitals and schools, and are not suitable for large-scale industrial production workshops, especially large-scale machinery production workshops. Due to the limitation of production needs and working conditions, the large-scale machinery production workshop has a large space and poor airtightness, so it is not suitable to install air conditioners. It is difficult to adapt to the placement of ordinary electric fans in different environments, and the small wind power cannot meet the purpose of fanning wind and heat in a large space. [0003] In order to solve the above problems, some existing enterprises design and manufacture larg...
