Driver and driven gears

Where the number of teeth on driver and driven gear are 40 and 20 respectively. And Driver gear is rotating with rpm and 10 N-m torque. Number of teeth on driver Gear (T1) = Number of teeth on driven Gear (T2) = Speed of Driver Gear (n1) = rpm. Torque acting on driver gear = 10 N-m. rotates. The ratio between the rotations of the tooth driver gear and the tooth driven gear is 3 to 1. That is, the gear ratio is 3 to 1. Using the colon notation, the gear ratio is The order of the two numbers in a ratio is very important. In this case, the ratio of the tooth driver gear and the tooth driven gear is File Size: KB. Each gear is fixed to an axle, and the axle drives a fan. The speed with which the fan turns is called the rotational speed of the axle. When a gear with many teeth drives a gear with fewer teeth, the driven gear turns faster, but with a smaller turning force than the driver gear.

What is the gear ratio of a tooth driver gear and a tooth driven gear? The gear ratio is Ask students to complete the Teeth Ratio and Gear Ratio columns in the table. Drawing of Rotations Gear Pair (driver, driven) Teeth on Driver Gear Teeth on Driven Gear Teeth Ratio (driver: driven) Gear Ratio (driver rotations: driven rotations). DRIVER gear is smaller than the DRIVEN gear. The general rule is -small to large gear means 'divide' the velocity ratio() by the rpm of the first gear. Divide 75 teeth by 25 teeth to find the velocity ratio. divide the 60rpm by the velocity ration (3). The answer is 20rpm. Gear drives can increase or decrease the speed of the driven shaft relative to the driver. This is achieved by using gears with different pitch diameters or numbers of teeth. A large driver coupled to a small driven gear increases the output speed. Conversely, using a small driver and a large driven gear produces the opposite result.
