Ferris wheel to take "sub-assembly method with" Install

Ferris wheel to take "sub-assembly method with" Install. Firstly the spindle and the ferris wheel bearing installation, which is the dot whole Ferris wheel; followed by the installation of the wheel and cockpit, wheel outside the racking several transparent cockpit, which can concept for hundreds of people; and finally electric drive mounting device, which is located in the Ferris wheel and bridge binding place, after opening the Ferris wheel can be controlled uniform rotation, revolution needs about 30 minutes to reach the highest point, with sweeping views of the surrounding, you can see within a radius of 40 km views. Ferris wheel means no gear wheel bearings four point contact ball slewing bearing, a separate type of bearings, it can be said that a two-way bearings can withstand axial load angular contact ball bearings.

The stress analysis of crankcase

According to the stress analysis of the crankcase, consider the strength, confirm the deformation amount and bearing clearance of crankcase and bearing, calculating miniature linear bearings life, and try to optimize the bearing and axle box.
The maximum deformation of 1.5MW four point contact ball slewing bearing and axle radial fan for 0.07mm. Considering the calculation results of deformation and bearing clearance  and the crankcase as steel body life difference within 5%, this value in practice is not a problem. The life of difference, life is shortened, then, must change the axle box design, improve the rigidity.
