Discussion Overview

The discussion revolves around a mechanical engineering project focused on determining a formula for the relationship between the number of teeth and gears required to transmit a pound of force. The scope includes design considerations and material properties, specifically steel.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks a formula for the number of teeth and gears needed for a pound of force, indicating a desire for practical examples.
  • Another participant emphasizes that the number and size of teeth depend on various factors, including gear diameter and material stress limits.
  • A participant argues that understanding the loads transmitted through gear teeth is essential, noting that there is no straightforward equation for this and that complex stress distributions require advanced techniques like optical methods and FEA.
  • Some participants express frustration with the expectations of quick responses without adequate questions or gratitude for previous contributions.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the inquiry, with some focusing on the complexity of the engineering problem while others are frustrated by the perceived lack of engagement and clarity in the original question. The discussion remains unresolved regarding the specific formula or example requested.

Contextual Notes

The discussion highlights limitations in the original question, including a lack of detail on the loads and conditions necessary for a precise answer. There is also an indication that the inquiry may not fit the intended forum section.

Trying to figure out a formula for the amount of teeth and amount of gears for a pound of force delivered.

This is a mechanical engineering/design problem, and not suitable for the tutorial section. I shall move it accordingly.

The number (and size) of teeth will depend on the diameter of the gear (root, or mean, or peak), and the stress limit criteria, which depends on the material.

Well I know that I just need a partial portion of my dirty work done like an example of lined up gears and teeth per pound. but I'll give you this much. Material: Steal
 
It doesn't work like that. You need to know the loads you will be transmitting through the gear teeth. You assume, worst case, that only a single tooth will be engaged at a time. There is no easy plug and chug equation to do this. This is why optical techniques and FEA are used to describe the very complex stress distributions around gear teeth.

>_> I asked an example, not The most efficient way. I'm unfortunately done with this site until I have a dumb question.
 
We don't want members here who ask half a question, and expect answers within 9 minutes of their original post, without showing any gratitude for the helpful (and correct) answers which were offered them.

Close the door quietly on your way out.
 
On that note, this thread is done. Best of luck!
