1 What are the mechanisms?
mechanisms are elements designed to transmit and transform forces and movements from a motor to a receiver. 2 Rating
mechanisms
movement transmission mechanism Mechanism
motion processing mechanism for directing the movement
mechanism to regulate the movement
energy storage mechanisms coupling mechanism
3 Mechanism
linear transmission lever: Found in equilibrium when the total force, F, by their distance away, d, the fulcrum is equal to the total resistance, R, by distance, r, to the point support. This Act is called the handle lever types
First Grade: support is between the strength and endurance
Second pleasure: The resistance is between the support and strength
Third degree: The force is between the fulcrum and the resistance pulley
fixed: It is in equilibrium when the force is resistance equal to the mobile pulley
: It is in equilibrium when equality holds
Hoist: One is in equilibrium when it meets this equality
F = R / 2n
4 Drivetrain

belt pulleys pulleys pulleys Train
Gears or toothed wheels -

chain
5 speed variation
For example, a cycle with a wheel smaller than the other, the Small
gives more big wheel turns
6 Mechanisms of transformation of the circular motion in straight
rack and pinion system screw-nut system
crank-set around
7 Mechanism of transformation of the circular motion in straight
Alternative
7.1
rod-crank assembly: This consists of a bar
manivelaa and crank call. Turning the crank wheel transmits the circular movement of the rod
making a sawing motion.
7.2 Crankshaft: A series of rods on the same axle bent, each axis
elbow serves as a crank and crank set is called
and eccentric cam 7.3
