MECHANISM
What is?
A part of a machine or a set of parts that work together.
CLASSIFICATION
Transmitting motion
Transforming motion
Controling and regular motion
Joining elements
Storing energy
Linear motion mechanisms
Levers
Is a rigid bar that is supported by a fulcrum
F x d= R x r :warning: (law of the lever)
TYPES
Class 1
Class 2
Class 3
Types of pulleys
Fixed pulley
Movable pulley
Compound pulley
Rotary motion mechanism
Friction drives
Pulleys with belt
Gear mechanism and cogwheels
Gear mechanisms with a chain
Gear train
Pulley trains with belts
variation in velocity
Worm gear
Mechanism that transform motion
From rotary into linear
Rack and pinion system
This uses a pinion that is a small cogwheel, mounted on a rack that is a toothed belt or bar
Nut and bolt system
This consists of a bolt or threaded bar and a nut that has the same interior diameter as the diameter of the bolt.
Winch and crank handle
intenor diameter as the diameter of the bolt crank handle that allows to pull or lift obiects.
From rotary into reciprocating motion
Crank-link-slide
Crankshaf
Cam
Eccentric cam
Other mechanisms
Mechanisms for controlling and directing motion
Disc brakes
Band brakes
Drum brakes
Mechanisms that store energy
by compression
by traction
by torsion
Connecting mechanisms
