Use of Gears-
- To contrary the administration of rotation
- To increase or decrease the speed of rotation
- To displace rotational motility to a dissimilar axis
- To decease along the rotation of 2 axis synchronized
Advantages of Teeth-
- They preclude slippage betwixt the gears - hence axles connected past times gears are ever synchronized precisely amongst 1 another.
- They become far possible to reach upward one's demand heed exact gear ratios - you lot simply count the compass out of teeth inwards the 2 gears too divide. So if 1 gear has lx teeth too around other has 20, the gear ratio when these 2 gears are connected together is 3:1.
- They become far too then that slight imperfections inwards the actual diameter too circumference of 2 gears don't matter. The gear ratio is controlled past times the compass out of teeth fifty-fifty if the diameters are a fleck off.
