PPT-Dynamic Mechanisms Gears

Gears are toothed wheels Gears are used to transmit motion Gears are also used to convert rotary motion to linear motion or visa versa Gears can be used to reduce or increase the torque. Students will learn how to use gears properly efficiently and effectively Predicting directional motion of a string of gears Class discussion of different building methods Explorin g gear setups gear ratios and directional changes Recording design a Cams. A cam is a machine part for transferring rotary motion to linear motion. In a radial plate cam, the cam is mounted on a rotating shaft. The motion is recieved by a follower. To see a cam in operation click on the link. Nanotechnology Simple Machines. Gears, Pulleys, & Sprockets. These three power train elements transfer energy through rotary motion. .

Gear pumps are a ubiquitous means to generate hydraulic power. Rugged simplicity, cost effective. The simplicity of gear pump design presents some liabilities. 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.
