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

Click For Summary
SUMMARY

This discussion focuses on selecting the appropriate dimensions for a power screw based on a specified maximum load, specifically using a Metric Trapezoidal thread as per ISO 2904 standards. Key calculations include determining the screw diameter, moment of torque, and efficiency. Participants reference the Machinery's Handbook as a valuable resource for understanding these calculations and design principles. The conversation highlights the necessity of precise engineering knowledge for effective design in mechanical applications.

PREREQUISITES
  • Understanding of Metric Trapezoidal thread specifications (ISO 2904)
  • Knowledge of torque calculations and efficiency metrics in mechanical design
  • Familiarity with basic principles of screw mechanics
  • Access to Machinery's Handbook for reference
NEXT STEPS
  • Research the calculation methods for determining screw diameter based on load requirements
  • Explore the principles of moment of torque in mechanical systems
  • Study the efficiency calculations for power screws and their impact on design
  • Review the relevant sections in Machinery's Handbook for detailed engineering guidelines
USEFUL FOR

Mechanical engineering students, design engineers, and anyone involved in the design and analysis of mechanical systems requiring power screws and load calculations.

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.
