How does an air ratchet wrench generate torque, and what is its maximum torque output?

An air ratchet wrench generates torque using compressed air as its power source. Here's how it works:

Air Motor: At the heart of an air ratchet wrench is an air motor, which is powered by compressed air supplied through an air hose connected to an air compressor. When the air supply is activated, the air motor converts the kinetic energy of the compressed air into rotational motion.

Gear Mechanism: The rotational motion generated by the air motor is transmitted to a gear mechanism within the wrench. This gear mechanism typically consists of a set of gears, including a pinion gear and an output gear, which work together to amplify the rotational force and transmit it to the output shaft of the wrench.

Ratchet Mechanism: The output shaft of the wrench is connected to a ratchet mechanism, which allows the shaft to rotate in one direction (clockwise or counterclockwise) while preventing it from rotating in the opposite direction. This ratcheting action allows the wrench to turn fasteners in tight spaces without having to remove and reposition the wrench for each turn.

Torque Output: The maximum torque output of an air ratchet wrench depends on several factors, including the size and design of the air motor, the efficiency of the gear mechanism, and the air pressure supplied to the wrench. Generally, air ratchet wrenches are available in a range of torque ratings, with maximum torque outputs typically ranging from around 25 to 150 foot-pounds (ft-lbs) or more.

It's important to note that the actual torque output of an air ratchet wrench may vary based on factors such as air pressure fluctuations, hose length and diameter, and the condition of the tool itself. Additionally, torque output may be adjustable on some models, allowing users to fine-tune the wrench for different applications and fastener sizes.
