Gears And Gear Ratios - Bowlesphysics.com
Types of Gears Bevel gears can be used to change the direction of drive in a gear system by 90 degrees. A good example is seen as the main mechanism for a hand drill. As the handle of the drill is turned in a vertical direction, the bevel gears change the rotation of the chuck to a horizontal rotation ... Read Here

Ratchets, springs, gear shafts and other gears can be designed as integral parts in a single moulding, thus elim-inating costly manufacturing and assembly operations. Tolerances for plastic gears are in some cases less critical than for metal gears because the inherent resiliency enables the teeth to conform to slight errors in pitch and profile. ...
