Transmission apparatus for contra-rotating impeller ventilation |
摘要 |
A transmission apparatus for contra-rotating impeller ventilation. According to the apparatus, flanges (13, 21) output to a first-stage impeller (14) and a second-stage impeller (18) to achieve contra-rotation of the impellers; tapered roller bearings (20) are arranged at both ends of a cross shaft (9) and can run at a high speed, so that the requirement on high rotating speed of the impellers can be met. The apparatus is a keel type transmission case, the cross shaft is used as the main body, and the case only bears a supporting force on the longitudinal shaft end of the cross shaft; therefore, the two sets of blades are closest to each other under a bevel gear transmission condition, so that the structure is more compact and the efficiency of a contra-rotating impeller ventilation device is improved. |
