How to Correctly Size Air Powered Gear Motors for a Heat Treat Car Drive System?

Click For Summary
SUMMARY

This discussion focuses on sizing air powered gear motors for a heat treat car drive system, specifically for a load range of 5000 to 12000 pounds. The user, a mechanic named Jim, seeks to replace a continuous cable loop drive with foot mounted air powered gear motors featuring V-type rollers, capable of traversing 15 feet in under 30 seconds. The recommendation is to utilize two motors to prevent racking and ensure stability on inverted angle iron tracks. Key considerations include roller diameter, motor specifications, and load management.

PREREQUISITES
  • Understanding of air powered gear motors
  • Knowledge of load calculations and weight distribution
  • Familiarity with roller design and specifications
  • Basic mechanical engineering principles related to drive systems
NEXT STEPS
  • Research air powered gear motor specifications and torque ratings
  • Learn about load distribution techniques for drive systems
  • Investigate roller diameter impact on motor performance
  • Explore mechanical design principles for stability in moving systems
USEFUL FOR

This discussion is beneficial for mechanics, engineers, and project managers involved in designing and implementing drive systems, particularly those transitioning from cable systems to air powered solutions in industrial applications.

Hello all I am very new to this sight and am not an engineer. I am a mechanic tasked with building a powered drive system for our heat treat car. We currently use a continuous cable loop drive but we would like to change it to air powered gear motors. My question is this, how to size it correctly.

I would like to use a foot mounted air powered gear motor with v type roller. At this point I can use any diameter roller under 8". These will run on inverted angle iron mounted to the floor. The load is variable between 5000# and 12000#. I am assuming due to the size and structure of the car that we would use 2 motors to avoid racking and possibly forcing the car off the track. I would like the car to traverse 15ft in less than 30 seconds.

Any guidance would be appreciated and if I am missing any needed information please let me know, thank you.

Jim
