Mechanisms
Rotary motion mechanisms.
These mechanisms transmit motion and effort in a circular way, from the input to the output. They include friction drives, pulley systems, gears and worm gears.
Friction drives.
Friction drives are made up of two or more wheels that are in contact. The first wheel is called the primary drive wheel. When it moves, it turns or drives the second or output wheel, causing it to move as well.
Pulleys with belt.
They consist of two pulleys or wheels that are a certain distance apart. Their axles are parallel and they rotate simultaneosly due to the effect of the belt.
Gear mechanisms and cogwheels.
Cogwheels are sets of wheels that have teeth called cogs.
Worm gear.
This is a screw that moves a helical cogwheel that is set perpendicular to the screw.
Linear motion mechanisms.
Levers.
A lever is a rigid bar that is supported by a fulcrum.
Types of levers
Class 2.
Class 3.
Class 1.
Fixed pulley.
A fixed pulley is a wheel that has a groove around it into which a rope, chain or belt fits.
Movable pulley.
A moveable pulley is a set of two pulleys, one is fixed while the other can move in a linear direction.
Compound pulley.
This is a system of fixed and moveable pulleys, often called block and tackle. If we use more pulleys, the system becomes more complex, but less effort is needed to move the load.
Other mechanisms.
Mechanisms for controlling and directing motion.
Mechanisms that store energy.
Connecting mechanisms.
Supports: bushings and bearings.
Mechanisms that transform motion.
From rotary into linear.
Rack and pinion system.
Nut and bolt system.
Winch and crank handle.
From rotary into reciprocating motion.
Crank-link-slider.
Crankshaft.
Cam.
Eccentric cam.
Around us we can see many moving objects and mechanisms that produce movement that we can also call motion..
