RC Blocked Diff - V2

thingiverse

This is a revised version of this design - http://www.thingiverse.com/thing:1715175 \nIt's based on this library - http://www.thingiverse.com/thing:3575/#files \nThe gears now have the same number of teeth, 10 teeth, making for an extremely powerful differential (larger teeth are harder to break) and a smaller differential at the same time (fewer teeth mean smaller gear size). The ratio is now 1:1.\nThe STL files provided here are designed with a large gear diameter of 16 mm. If you want a larger or smaller differential, simply adjust the "SCALE_FACTOR" variable in the OpenScad source code and re-generate.\nYou can see this design in action - https://www.youtube.com/watch?v=Fl0kDC48Tu8\nThis design utilizes 4 bearings (D8 x d5 x 2.5 mm) to ensure smooth operation. You can customize the bearing size by checking "BEARING_OUTER_DIAMETER" and "BEARING_WIDTH" variables.\nThis design uses 4 M2 screws to fix the gears on the axle, which is drilled beforehand. You can change this (see "GEAR_FIX_SCREW_DIAMETER").\nThis design utilizes 5 mm precision rods. If you want to use different rod size, check the "GEAR_BORE_DIAMETER" variable.\nYou can generate an open axle (where you can see the gears inside) by calling "axle_top(open_top=1);" and a closed axle (so no dust gets inside) by calling "axle_top(open_top=0);".
