2. Pulley - Wikipedia

   en.wikipedia.org/wiki/Pulley

   Flat belt on a belt pulley Belt and pulley system Cone pulley driven from above by a line shaft. A belt and pulley system is characterized by two or more pulleys in common to a belt. This allows for mechanical power, torque, and speed to be transmitted across axles. If the pulleys are of differing diameters, a mechanical advantage is realized.

3. Block and tackle - Wikipedia

   en.wikipedia.org/wiki/Block_and_tackle

   A block and tackle [1] [2] or only tackle [3] is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads.. The pulleys are assembled to form blocks and then blocks are paired so that one is fixed and one moves with the load.

4. Mechanical advantage device - Wikipedia

   en.wikipedia.org/wiki/Mechanical_advantage_device

   Examples of rope and pulley systems illustrating mechanical advantage. Consider lifting a weight with rope and pulleys. A rope looped through a pulley attached to a fixed spot, e.g. a barn roof rafter, and attached to the weight is called a single pulley. It has a mechanical advantage (MA) = 1 (assuming frictionless bearings in the pulley ...

5. Belt (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Belt_(mechanical)

   Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the ...

6. Mechanical advantage - Wikipedia

   en.wikipedia.org/wiki/Mechanical_advantage

   Mechanisms consisting of two sprockets connected by a chain, or two pulleys connected by a belt are designed to provide a specific mechanical advantage in power transmission systems. The velocity v of the chain or belt is the same when in contact with the two sprockets or pulleys: = =,

7. Conveyor belt - Wikipedia

   en.wikipedia.org/wiki/Conveyor_belt

   A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems.A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them.

8. Line shaft - Wikipedia

   en.wikipedia.org/wiki/Line_shaft

   For example, a 40" pulley at 100 rpm would turn a 20" pulley at 200 rpm. Pulleys solidly attached ("fast") to the shaft could be combined with adjacent pulleys that turned freely ("loose") on the shaft (idlers). In this configuration the belt could be maneuvered onto the idler to stop power transmission or onto the solid pulley to convey the power.

9. Differential pulley - Wikipedia

   en.wikipedia.org/wiki/Differential_pulley

   (The two pulleys are joined together such that they rotate as a unit on the single shaft that they share.) The relative sizing of the two connected pulleys determines the maximum weight that can be lifted by hand. If the pulley radii are close enough, then the load will remain in place (and not lower under the force of gravity) until the chain ...
