1.What are gears and what are they used for?
-Are mechanical elemnts designed to transmit turning movements
2.What does it mean when two gears "engage"?
-It means these teeth fit in those of another similar wheel.
3.What are the two main characteristics of the gears? How are they Represented?
-The number of teeths (Z) and the rotational speed (N)
4.What happens if two gears have a different number of teeth? And if they Have the same number?
-The small gear rotate faster than the big gear; They rotate at the same speed.
5.In a couple of gears, what mission does the motor gear have? And the Output gear?
-The motor gear pushes; The output gear recives the movement
6.Depending on their shape, what types of gears, are there?
-Cylindrical and conical gears
7.What is the difference between a gear with straight teeth and one with Helical teeth?
-The straight teeth follow straight lines the helical teeth have curved teeths.
8.What does it mean when two gears reverse the rotational direction?
-Motor gear rotate clockwise; Driven gear rotate counter clockwise
9.What is an idler gear? And a gear train? What are they good for?
-The idler gear aims to reverse the turning rotation; Are mechanims formed by more than 2 gears; They are good if you want to have the same rotational direction
10.What is a reducing gear mechanism of two gears?
-The motor gear is smaller then the output gear, the output gear turn motor slowly, it will be able to carry out more force.
11.What characteristics does a two gear speed multiplier mechanism have?
-The motor gear is bigger than the output gear, the output gear rotate faster but carry out less force.
12.What is a compound gear? What is it used for? Accompany your Explanations of a drawing.
-Are two gears of different sizes that are joined, moving, therefore, at the same speed; Are gears used to reduce the speed of a motor
13.What does it mean when the gears transmit the movement accurately? What Advantages and disadvantages can this feature have?
-They can´t slide; PREGUNTALE A OTRO YO NO LA ENCUENTRO
