What happens when you have equal force on opposing sides of a 2:1 gear train?

AI Thread Summary
In a 2:1 gear train with opposing pistons experiencing equal forces, the system will initially accelerate, but the outcome depends on various factors such as the size of the gears and how forces are applied. The setup described involves a sealed chamber where both pistons are exposed to ambient pressure, which complicates the dynamics. The expectation is that piston 2 will move towards the gear train, potentially limiting the chamber's volume instead of increasing it. To achieve an increase in volume when ambient pressure rises, alternative designs or mechanisms may be necessary. The discussion highlights the need for further exploration of gear configurations and force applications to meet the desired outcome.

I have studied how gear trains work for a project I am working on, but can't find an analogous situation where the forces in the gear train oppose each other. Can someone help me?

I have a 2:1 gear ratio on a dual rack and pinion gear train connected to opposing pistons, and there is equal force on both pistons (force = 2). In order to help me understand what will happen, can you tell me in what direction will each piston move and how far?

Force -->|piston1|----------(1:2 gear train)----------|piston2|<-- Force

If the forces are equal at first, the system will accelerate. What happens then requires more information. How are the forces applied? How big are the gears? How big are the crankshafts?
 
The device is in an environment with ambient pressure, so the forces are equal on both pistons. The top of the pistons are exposed to the environment and there is a single sealed chamber connecting the pistons and containing the gear train. The opposing pistons are connected to shafts (pinions) attached to a 2:1 gear train. Both gears are on the same axis (like a minute hand and an hour hand but in opposite directions). One piston pinion is connected to the 1 gear, and the other piston pinion is connected to the 2 gear. No crankshaft.

Normally, when the ambient pressure increase, the volume of the piston chamber would decrease. I would like to use a gear system so that when the ambient pressure increases, the volume of the piston chamber increases as well.

However, I think piston 2 will be pushed all the way to the gear train keeping the same volume in the piston chamber. Am I right? Is there any way to accomplish my goal of increasing the volume?

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
