ENGR 100 Lecture Notes - Lecture 13: Gear Train
Document Summary
In order to spin the generator faster use transmission: this is useful to change shaft speeds and shaft torques, transmissions. Mechanical device to change speeds of a shaft. Examples: gears - transmit power from one part of machine to another. Passing power from one gear wheel to another, you can do one of three things: Increase speed if one wheel has more teeth than another second wheel turns faster with less force. Increase force more teeth moves slower than less teeth but has more force: change direction - if the first one turns cw, the second one must turn ccw, belts and pulleys, chain and sprockets. Mechanical device to change speeds of a shaft: speed. As long as the belt doesn"t slip: u. 2 is the force of pulley 2 on the belt; it becomes the tension in the belt: transmission: torque. The belt tension applies a force f (=f. F is force of belt on pulley; f.
