RAC v2.0 · 模型 267812
This is the updated version of my first entry. It has the same working principle as the first version with several updates to improve its performance, which include: 1. Shovels geometry was modified to ensure sand falls into the drum in low gravity. 2. Angular contact bearing SKF 3204-A was added to compensate moment load on the drum's shaft. 3. Cam clutch bearing was modified to compensate bigger drum's shaft dimension. 4. The drum's shaft and its structure was modified to be more rigid under full load. 5. The flange that connects the RASSOR main shaft and the bucket was modified. This version has an improved load capacity, which is 32.6 litres, thus increased the fill ratio to 56.9%. Aluminium 6061 is still being used on the overall design and the weight was decreased to 4.6kg. A link to the simple demonstration video also has been provided to demonstrates that the shovels are able to transport the sand to the drum opening at the top and continuously filling the drum efficiently. Further refinement of the shovel geometry is recommended for peak performance in low gravity. Thank you for all commentators that has made valuable recommendations to improve this design.
