WebNov 18, 2024 · Question: Calculate the Speed and torque of the output shaft for a simple gear train. Where the number of teeth on driver and driven … WebA gear’s transmission torque changes as it increases or decreases speed. Generally, by reducing the speed, a small torque at the input side is transmitted as a larger torque at the output side. The calculation of torque depends on the number of teeth. Let me explain with a diagram using pitch circle diameters.
WebJul 28, 2024 · The red and blue gears interact via meshing teeth, then the blue and yellow gears are on the same shaft, then finally the yellow and green gears interact via meshing teeth. A concept that is commonly used in gear trains that is not commonly used in belt driven systems is the concept of the gear ratio. For any gear train, the gear ratio is ... WebSpur Gear Forces. The first thing we’re going to do is create a quick free body diagram on a gear tooth. We can make our calculations based on the pitch circle diameter. We have the tangential force, F t which is the input force that transmits motion. We can find the tangential force from the torque on the gear.
