How to choose the right power screw dimensions given the maximum load

Click For Summary

Discussion Overview

The discussion revolves around the design of a jockey wheel and power screw for a university project, specifically focusing on how to determine the appropriate screw dimensions based on a given maximum load. The scope includes calculations related to torque and efficiency, as well as the specifications of a Metric Trapezoidal thread according to ISO 2904.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant expresses confusion about how to derive the screw diameter and dimensions from the maximum load provided for their project.
  • Another participant inquires if the original poster is familiar with "Machinery's," suggesting it may contain relevant information.
  • There is a clarification from the original poster indicating a lack of familiarity with machines, which leads to further discussion about the resource "Machinery's Handbook."
  • A later reply confirms that the information sought by the original poster is indeed found in "Machinery's Handbook."

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the specific calculations or methods for determining screw dimensions, as the original poster's question remains unresolved. However, there is agreement on the potential usefulness of "Machinery's Handbook" as a resource.

Contextual Notes

The discussion does not provide specific methodologies or formulas for calculating screw dimensions, and there is an assumption that the original poster will seek information from external resources.

TL;DR
Choosing an appropriate Metric ISO 2904 Power Screw given the maximum load
Hi, So I have a uni project and were required to design a jockey wheel and corresponding power screw. We're given a maximum load and have to do the relevant calculations, moment of torque, efficiency etc. My question is I don't understand how to take the given maximum load and find the relevant screw diameter and dimensions, the screw we have to use must be a Metric Trapezoidal thread ISO 2904. Any help would be much appreciated.

I'm not sure what you mean, if you're asking am I familiar with Machines the answer is no though.
 
Indeed.
