Mechanisms - Coggle Diagram

- - - - Equation: N1 x D1 = N2 x D2
  - - - Equation: N1 x Z1 = N2 x Z2
    - - There are two cogwheels with pararell axes that are certain distance apart. They rotate simultaneosly. Uses: industrial machinery, engine and motors..
        
        Equation: N1 x Z1 = N2 x Z2
  - - - N wheel = N screw x Z grooves / Z wheel
  - - - Equation: N4/N1 = Z1 x Z3 / Z2 x Z4
  - - - Equation: N4/N1 = D1 x D3/D2 x D4
        
        Variation of velocity
- - - - The mechanisms used to reduce velocity are called brakes. There are several types:
        
        Disk brakes
        
        Band brakes
        
        Drum brakes
  - - - Springs work in different ways:
        
        By compression
        
        By traction
        
        By torsion
  - - - the axle/shaft is inserted in a plane circular piece
    - - are made up of two concentric rings with balls or rollers
- - - - Equation: L= P x Z x N
        
        Uses: bench drills, corkscrews, vehicle stering
    - - Is a bolt and a nut that has the same interior diameter as the diameter of the bolt. Uses: presses, taps, car jacks...
    - - A winch and crank handle system consists of a drum that rotates and a crank handle that allows to pull or lift objects. Uses: roller blinds, coffee grinders, crushing machines and cranes.
        
        Equation: F x d = R x r
  - - - This device was very important in the development of steam engines. Uses: internal combustion energy, windscreen wipers and machine tools.
    - - A crankshaft transforms the rotary motion of an axle into a reciprocating motion with different connecting rods of moving at different times. Uses: combustion engines and sewing machines.
    - - A cam transforms rotary motion into reciprocating in the follower or bar. A set of cams fixed on the same axle is called camshaft
    - - It transforms the rotary motion of the wheel into reciprocating motion in the follower. Uses: sewing machines, windscreem wipers.
        
        The distance between the centre of the circunference is called eccetric
- - - - A lever is a rigid bar that is supported by a fulcrum
        
        Equation: F x d = R x r
        
        We have 3 types of class of levers
        
        Class 1
        
        The fulcrum is between the effort applied and the resistence. The effect of the ford applied can be multiplied or reduced.
        
        Class 2
        
        The resistance is between the fulcrum and the effort applied. The effect of effort applied is always multiplied
        
        Class 3
        
        The effort applied is between the fulcrum and the resistence. The effect of the effort applied is always reduced.
    - - Is a wheel that has a groove around it into which a rope, chain or belt fits. It rotates around an axel that is fixed to an immobile surface. Uses: wells and gym equipment
        
        Equation: F = R
    - - Is a set of two pulleys
        
        Equation: F= R/2
    - - This is a system of compound pulley, often called block and tackle. If we use more pulleys, the system become more complex, but less effort is needed. Uses: lifts, good lifts and cranes
        
        Equation: F= R/2n
        
        Equation: F= R/2 x N
