Abstract
A bevel-gear fan speed increaser comprises a spindle which is provided in the gear box and pressed loading and cooperated with the planet carrier which is fixed to integrate a whole, two stages of the planetary transmission which are all the floating of sun gear and a fixed planet carrier. The device is characterized in that the internal and the external tooth of the speed increaser adopt the bevel-gear transmission; the two ends of one stage planet carrier adopts the centering roller bearings, and double-row entering roller bearings are provided in the one stage planet wheel. The two-stage planet carrier adopts the deep groove ball bearing on the left end, and the spherical thrust roller bearing on the right end. Both of the two sides of the two-stage planet wheel adopt the cylindrical roller bearing, and the hollow shaft which is parallel to the axial grade adopts the centering roller bearings on one end and the cylindrical roller bearing on the other end. One end of the output shaft which is parallel to the axial grade cylindrical roller bearing, and the other end is a cylindrical roller bearing and a four-point contact ball bearing. The speed increaser combines above bearing reasonably, which not only makes full use of the advantages of every bearing and shortens the production period, but also ensures the service time of the speed increaser and decreases the production cost. So the speed increaser is suitable to mass produce, and realizes the uniform load efficiently.
