RASSOR Scroll Drum · 模型 267889
This Drum is designed to have a continuous cut/Shear to reduce vibration and torque reaction in the low gravity environment. At maximum depth of 1/2 the Drum diameter the Cut width is 175mm This could be assembled in Carbon Fiber, Aluminum or magnesium, or using Additive manufacturing. Details: OD: 450mm Overall Width: 360mm Cutting Width: 175mm or less depending on depth of drum Cutting Edges: 1 Cut depth: aprox. up to 25mm Mass: Carbon Fiber/Titanium: 1.673kg Aluminum: 3.1kg Magnesium: 2.23kg Capacity: (note includes 30mm allowance for central drive shaft) See Images for estimated volumes Internal Volume(theoretical maximum): 44.6 liters Inner Space Volume(Empty Chutes): 43 Liters Estimated Achievable Volume: 42L(Based on Simulation) Fill Ratio: 90-95% of theoretical Materials: Carbon Fiber/Titanium, T6 Magnesium or T6 Aluminum Anodized for wear resistance Teeth: Titanium, Carbide, Cast Ceramic or Hardened Steel, Machined or Cast, Riveted to Shell(Al Rivets) TiN coated for reduced wear. Construction: Sides and Shell: bonded, Welded Scoop and Shell: Bonded, Welded Scoop and Teeth: Riveted Design Features: Design does not require continuous rotation to maintain load, allowing for lower energy usage Scroll Cut allows for constant engagement with medium reducing vibration etc especially in low gravity environment Scroll design allows larger debris to be pushed or rolled off to the side reducing potential for blockage of intake Allows for smoother intake of material compared to scoops Welded Construction: Removes need for internal structures to maximize storage and minimize potential build up and blockages Offset design: self regulating depth of cut Single cutting edges: Increase available shearing force Scroll shape of blade increases blade life as blade wear will be spread along edge progressively over time. Radiused cutting edge: Reduce Digging in, uses a shearing action to remove material rather than an breaking digging action reducing chance of grabbing. Manufacture: Manufacture methods are common and well known Simple and quick assembly of components
