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

AI Thread Summary
To correctly size air-powered gear motors for a heat treat car drive system, it's essential to consider the load range of 5,000 to 12,000 pounds and the desired speed of traversing 15 feet in under 30 seconds. The use of two motors is recommended to prevent racking and ensure stability on the track. A foot-mounted air-powered gear motor with a V-type roller is preferred, with a maximum roller diameter of 8 inches. Additional details about the specific torque requirements and motor specifications may be needed for accurate sizing. Clarifying these factors will help in selecting the appropriate motors for the application.

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

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
