Our TaskDesigning a gearbox to complete given task:
Pulling a mass of minimum 10kg up a sloped ramp of ~46 degrees
Must pull the mass for a minimum length of 50cm
Has to pull the mass up the slope in the quickest amount of time
Is to perform the task utilising only the Motor provided
Refer to the criteria in the unit outline.
Our TaskPulling a load up a rampDesign gearbox for task

Theory relating to our task?
Analysing the Performance FormulaPerformance is calculated according to the formula:
P = m*g*h m*g*h t*V*I t*D^3
Important factors to minimise - D (longest Axial Distance) t (time taken to travel 50cm)Must base design around a compromise between the two to obtain greatest performance.
Initial Ideas For DesignKeep it simpleSimple constant mesh arrangement of spur gears with trains - Worried about torquePlanetary gears/Epicyclic gearbox - Compact - May be too difficultKeep a small footprint for the gearbox
Offset gearbox arrangement
