SUMMARY

The discussion focuses on strategies to reduce the gear ratio of a 20:1 worm gear system. Key methods include reducing the pitch of the worm gear and increasing the number of teeth on the spur gear. The user is specifically seeking smaller pitch worms and gears with more teeth, particularly from SDP-SI, which offers a range of gear options. The inquiry also touches on the potential use of bevel gears as an alternative solution.

PREREQUISITES
  • Understanding of gear ratios and their impact on mechanical systems
  • Familiarity with worm gear mechanics and terminology
  • Knowledge of gear pitch and tooth count implications
  • Experience with sourcing mechanical components from suppliers like SDP-SI
NEXT STEPS
  • Research gear pitch reduction techniques for worm gears
  • Explore alternative suppliers for high-tooth-count spur gears
  • Investigate bevel gear configurations and their applications
  • Learn about gear design principles to optimize performance
USEFUL FOR

Mechanical engineers, hobbyists in robotics, and anyone involved in gear design and optimization will benefit from this discussion.

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?
