NASA Rassor Drum MK3 · 模型 267805
OVERALL DESIGN NASA Rassor Drum MK3 is a lightweight excavating device. This model is designed to collect and transfer regolith. Inside, the cylindrical tray has a locking mechanism that is based on a bike freewheel. The inside tray is designed to lock in reverse and to prevent the regolith from escaping the drum while collecting. The outside cylinders have a thickness of 88.9 mm not including the protective outer rim. The thickness of the middle is 63.5 mm thick for extra strength. I chose the cylindrical shape so the drum could withstand the pressure better. CONSTRUCTING DESIGN Fabricating the Rassor Drum consists of 41 parts put together in 4 assemblies. Beginning with the right cylinder. Second, you connect the outer rim. When that is connected you can add the internal assemblies. starting with the press-fit 6061 aluminum ring. you can connect the inner blocker with the assembly by joining the aluminum ring with the locking mechanisms through the four bolt holes. Once that is assembled, you will proceed on the center with the rim ending with the left cylinder and rim. Finally, you will connect the other side of the locking system with the press-fit aluminum ring. SPECS: FILL RATIO OVER 63% TOTAL WIDTH OF SCOOPS 152MM DRUM MASS 4.98 KG DRUM DIAMETER 380MM DRUM LENGTH 251MM MAXIMUM CAPACITY OVER 42.3 LITERS
