3d clock gears1/31/2024 ![]() I had to hack into the code to get what I wanted and get something that worked (feature request will follow) I started with the Assembly 4 to animate two cycloid gears and optimize the meshing I used the Part Design workbench, the Gear workbench, the Assembly 4 workbench and the fastener Workbench My first idea was to redo clocks that I already made in Fusion, but then moved on a totally new project, one that can run over 24 hours I have used Fusion 360 for a couple years and while I am not a clock maker, I already have some experience designing 3D printed clocks. The cycloid gear is what made me want to experiment more with freeCAD. I also want to share the link to the whole file with the following creative commons license: BY-NC-SAįinally here is a link to the latest video of the progress of the clock on my YouTube Chanel:Ĭhecking out FreeCAD, I found the gear workbench with all its options. ![]() Here is a picture of the 3D printed realisation: Here is a rendering of the assembly in freeCAD: Eirik Brandal has updated components for the project titled várhafsóll.Here is my mechanical clock that I have designed with FreeCAD 0.19īut first, I would like to thank all the developers for this awesome program, as well as the workbenches.kelvinA has added a new log for Coaxial Hotend.mrpendent has updated the log for The Grimoire Macropad.mrpendent has updated details to The Grimoire Macropad.deltaterminal01 has added PLANKuter to Portable workstation / lab.benhamal liked ultra low cost pH amplifier circuit for 3.3V MCU's.deltaterminal01 has added Acorna Stratos to Portable workstation / lab.deltaterminal01 has added emuDeck01 to Portable workstation / lab.andriy.malyshenko has added MG873 as a contributor to Orange Pi Zero native network boot.Jack on Squeeze Over A Minute Of Movie Filming Onto A 35mm Still Cartridge.Jake on Patent Spat Leaves DJI Owing Textron $279M.Frank on Getting Ready For Act 2 Of The Great American Eclipse.Charles Lamb on Cocoa Press Chocolate 3D Printer Offered As DIY Kit.Paul on Cocoa Press Chocolate 3D Printer Offered As DIY Kit.DrWizard on Getting Ready For Act 2 Of The Great American Eclipse.This Week In Security: Session Puzzling, Session Keys, And Speculation 7 Comments Posted in clock hacks, cnc hacks Tagged 3d printed, clock, cnc, gears, lathe Post navigation If you’re looking for more beautiful artistic clocks, why not check out this circuit sculpture one? Mechanical advantage isn’t in favor and the stepper skips some steps and it slowly makes its way towards the next second digit of the hour. A fatal design flaw on the smallest disk became apparent as it needs to turn a sixth of the circle whereas the outer circle is just turning a tenth of the circle. He mentioned that tighter tolerances on the gears would likely help there. The numbers don’t quite line up perfectly, which is unfortunate. Some 3d printed numbers dropped into the CNCed slots offers much-improved readability.Ī few problems became apparent once the system was together. He did have to adjust and recut a few gears but most of the assembly came together nicely. A single stepper motor drives the whole clock, which admits is a bit of a cheat since trying to add springs and an escapement would add complexity to an already complex clock. Most of the clock is made of up stacked gear assemblies, geneva drives, and many bearings. So the clock should show 10:25 instead of moving hands to the 10 and the 5. The basic idea of the clock is that the numbers move on the clock, not the hands. The initial design was made in Fusion360 over a week and then in a somewhat bold move, started up the CNC and cut all the parts out of valchromat. In that spirit, set out to make a large mechanical clock with complex gears. It could just be that we as humans are fascinated by the concept of time or that making a piece of functional art appeals to our utilitarian sense. One of the most common projects we see here at Hackaday is a clock.
