Forces gears cause to the shaft (spur gears) - force diagram

Click For Summary
SUMMARY

The discussion focuses on analyzing the forces acting on shaft AB in a spur gear system. Participants emphasize the importance of including bearing forces, which consist of radial and tangential components. The initial diagram presented by a user omits these bearing forces, which are crucial for a complete understanding of the force dynamics. The consensus is that accurately representing all forces, including those from bearings, is essential for a thorough analysis.

PREREQUISITES
  • Understanding of basic mechanics, specifically force analysis
  • Familiarity with spur gear systems and their operational principles
  • Knowledge of bearing types and their force characteristics
  • Ability to create and interpret force diagrams
NEXT STEPS
  • Research the role of bearings in mechanical systems, focusing on radial and tangential forces
  • Study the principles of force diagrams in mechanical engineering
  • Learn about the dynamics of spur gears and their impact on shaft forces
  • Explore advanced topics in shaft design and load analysis
USEFUL FOR

Mechanical engineers, students studying mechanical systems, and anyone involved in the design and analysis of gear-driven machinery will benefit from this discussion.

The Attempt at a Solution



I've ignored the bearings for now... but I know each of them has 2 forces, 1 in the radial direction and the other in the tangential direction ... Anyway, this is my diagram (sans bearing forces)

I assumed shaft AB rotates clockwise

Hey Fp!

Looks good!
I'd add the forces in the bearings A and B as well though.
