mechanical components Flashcards
spur gears
bigger is driver
mesh together
gear trains
similar to spur gears, made up of 2 or more gears
idler
another gear placed in between two others to make them turn the same direction
compound gears
a number of gears fixed together
rack and pinion
flat and round gear - chair lift
rotary motion
follows path of a circle
r speed = number of revs/time taken
linear motion
movement in a straight line
oscillating motion
similar to rotary but like a clock pendulum
reciprocating motion
similar to linear motion but goes back and forth
how to work out force mutiplier
input arm length/output arm length
what does a bell crank do
changes the direction of motion - can transfer it round a rouner
what does a peg and slot do
used to convert rotary motion into oscillating motion
