Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work. Gears, Pulleys, & Sprockets. These three power train elements transfer energy through rotary motion. . Change the speed of rotation. Change the direction of rotation. Change the amount of torque available to do work . Pages 43-47. Student Performance Objectives. State the two cross-over gears and why they should be avoided.. State what duplicate gears are and how they effect the number of gears available for use.. Manual Transmissions . and Transaxles. Transmission Versus Transaxle. RWD vehicles use a transmission. A drive shaft links the transmission to the differential and drive axles. FWD vehicles use a transaxle. What Really Drives Them. Effectors and Actuators. Effector. An . effector. . is any device on a robot that has an effect (impact or . influence) on . the environment. .. Effectors range from legs and wheels to arms and fingers. The robot’s . © 2012 Project Lead The Way, Inc.. Principles of Engineering. Gears, Pulleys, & Sprockets.

These three power train elements transfer energy through rotary motion. . Change the speed of rotation. They all use gears to . increase. , . decrease. , or . redirect. power.. . . Gears can be found in many different sizes. A mechanical wind-up watch has very small gears, while the gears used to lift a bridge to allow ships to pass underneath are . The Speed of any driven gear is determined by calculating the gear ratio using the driven gear as the output gear along with the input gear and ignoring all other gears in between. MECH1200. Whether an extra gear in a gear train is an idler or drives an extra shaft,. © 2012 Project Lead The Way, Inc.. Principles of Engineering. Gears, Pulleys, & Sprockets.

EXAMPLE PROBLEMS AND QUESTIONS. GEAR…... Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work. Gears. A gear is a simple machine like a lever. The larger the diameter of the gear the longer the lever. What are Gears used for?. Ensure positive motion. Reverse the direction of rotation. Increase or decrease the speed of rotation.
