Transmission For Big Gears

thingiverse

Transmission with safety clutch for custom cog work in steampunk or dieselpunkt installations. This thing works in conjunction with my [big cogs](https://www.thingiverse.com/thing:4514161). It is connected to the bigger gears (all witch are fitted with 608 bearings) by an shallow ring witch is to be glued to the hub of the gear. Running the gears on different speeds makes the visual appearance of the installation much more interesting. The safety clutch protects fingers from being squished in the installation. Even though the reduction makes for a higher torque the safety clutch limits the torque in the reduced branch of the transmission. This is done by an springy ring witch engages with both cogs. If the torque gets to high is starts skipping while making an noticeable noise. The actual torque is determind by the stiffens of the ring. For higher torque it can be upscaled in z direction or slightly reduced in x/y direction. Spacers inside the cogs are taking the axial lode from the bearings to reduce resistance. the whol constraption is held together with an M4x60 screw.
