Systems of Gear Teeth

The following four systems of gear teeth are commonly used in practice: 1.   14 ½O  Composite system 2.   14 ½O …

Advantages of Cycloidal gear teeth

1.  Since the cycloidal teeth have wider flanks, therefore the cycloidal gears are stronger than the involute gears, for…

Forms of Teeth

Involute Profile The following examples are involute spur gears. We use the word involute because the contour of gear teeth…

Conjugate Profiles

To obtain the expected velocity ratio of two tooth profiles, the normal line of their profiles must pass through the…

Constant Velocity Ratio

For a constant velocity ratio, the position of P should remain unchanged. In this case, the motion transmission between two…

Neither parallel nor intersecting shafts

Helical gears may be used to mesh two shaftsthat are not parallel, although they are still primarily use…

Gears for connecting parallel shafts

1.      Spur gears: Spur gears are the most common type of gears. They have straight teeth,and are mounted on parallel…
