Our new gearbox has the same dimensions as a regular gearbox.
It can fit into you existing products with little effort.
But it's a cycloid drive. Meaning it can run to 5.5x overload torque (as compared to 3x on a planetary system).
This means your robots can accelerate faster. They can can reach higher speeds. And they can continually run at these top speeds.
The power of a cycloid drive - miniaturized. Now available in 1" - 4" sizes.
If you can accelerate faster, you can hit a faster top speed. Movement times typically range from 1/2 a second to 2 seconds, so top speed has to be obtained quickly for it to matter. This new gearbox gives you large acceleration early enough and fast enough to actually make a difference in your positioning time.
Cycloids offer better shock loading than involute gears. This means you can push your start-stop acceleration further than you could before, and continually run it at this new limit. Duty cycle is far less of a concern. than with typical gearboxes.
The internal components are bigger than that of a planetary gearhead. Bigger components mean manufacturing tolerances have less of an effect, percentage-wise. This means lower backlash and better position repeatability.
The newest warehouse robots can climb up shelves to get the product. This is an overhead hazard, and usually requires a significant safety factor.
With a cycloid gearbox, you don't need to upsize components to meet this safety factor requirement. The robot can be small and still have a high safety factor under conditions like load-bounce, stutter, and E-stop. This improves agility to go around corners, and helps keep them to a manageable weight for human interaction.
Cobots aren't fast enough in solo-mode to make back their costs, when compared to dedicated robots. You would have to go to a bigger gearbox to address the acceleration loads and E-stop requirements, which increases cost.
Now, cobots can reach faster speeds to become cost-competitive. We can do this with lower gear ratios, meaning faster speeds. The positioning accuracy stays the same - the resolution that is lost on faster ratios is made back with the lower backlash of the gearbox.
