How can i speed up a 20:1 worm gear

[TheCollector]

i have a 20:1 worm gear but would like to lower the ratio as much as possible. what can i do to lower the ratio? the lower the better

Reduce the pitch of the worm gear, or increase the number of teeth on the spur.

the gear I am using is tiny, like a half inch and it only comes in 20 teeth. the only worm i can find for it is 48 pitch. I am looking at https://sdp-si.com/ only so are there any other sites that have half inch or even better 3/16 gears with more teeth and worms with smaller pitches?

What are SDP's part numbers of the gears you are using? Can you use bevel gears?

I understand your desire to lower the ratio of your 20:1 worm gear in order to increase its speed. There are a few potential solutions you could explore to achieve this.

Firstly, you could try using a smaller worm gear with a larger gear wheel. This would effectively reduce the gear ratio, resulting in a higher speed output. However, this may also decrease the torque output of the system, so it is important to consider the intended use of the gear and the necessary power requirements.

Another option would be to use a different type of gear system altogether, such as a planetary gear system. This type of gear system can achieve high gear ratios with minimal space requirements, allowing for a smaller gear ratio and higher speed output.

Additionally, you could consider optimizing the efficiency of your current gear system. This could involve ensuring proper lubrication and reducing any friction or resistance in the gears, which can improve overall performance and potentially increase speed.

Ultimately, the best solution for lowering the gear ratio will depend on your specific needs and constraints. It may be helpful to consult with a mechanical engineer or expert in gear systems to determine the most effective approach for your specific situation.
