![]() After fine tuning the design, I was able to switch the gears to a 54:24 gear ratio and a 1" winding drum to provide an 8 day run time. Oops, I just realized that the image above shows the 4-day weight train with a 44:34 gear ratio and a 1.1" winding drum. Gear 4 with two 18 tooth pinions is the first one, followed by the ratchets, and the weight drum (after inserting a 608 bearing into the pocket). The gears should be assembled starting from the bottom gear to the highest to allow clearance. The standoffs are not shown, but they would position the frame 1" away from the wall to provide clearance for the pendulum. The picture below shows all of the axles in place, although they will get placed as each gear get added. The standoffs and keyhole hanger should be attached to the back of the frame as the first step. One of my long term goals is to learn photo-realistic rendering in TurboCAD to make the diagrams even better. The build in the next few sections shows a rough rendering of the clock in 3D form. For now I will just leave it as "print everything and cut the axles to length". There are a few preparation steps that need to be completed before assembly. This section shows the process of assembling the gears into the frame. The load is significantly below their design limit so I am expecting them to last a long time. I experimented with several different sized bearings and picked a size that allowed a pendulum to "free swing" the longest. The pallet has tiny ball bearings to support the weight of the pendulum. The escapement and pallet were also made slightly thicker to provide a larger wear surface. There are two 608 skateboard bearings supporting the weight of gear 8. Gears 7 and 8 have the most weight on them, so they were made thicker. The gear thicknesses and clearances were defined using the following mockup. There are two 18 tooth pinions on gear 4 with a friction fit to allow setting the time. Gear 5 and 6 form a secondary path for the minute hand to drive the hour hand. Each gear in the train rotates slightly faster, until it gets to the escapement rotating every 39.5 seconds. The weight shell has a pulley, so a 52" drop unwinds 104" of cord. Here is a diagram showing the clock gear connectivity and speed. The rest of the gears are labeled sequentially towards the weight drum. I suppose the pallet could have been called gear 0, but I simply call it the pallet. There are eight gear sets labeled mostly starting with the escapement labeled as gear 1. Let's start with the naming convention used when designing the clock. ![]() Support All Android Mobile Phone Army Clock 3D 2.Here are some details about the clock design and gear ratios used. ![]() ![]() This timer analog and digital clock have12 hour & 24 hourĪnalog clock as live wallpapers for any smart phone.Ĭalendar of the year in your choice format.
