Advantages of Cycloidal gear teeth

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

Forms of Teeth

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

Conjugate Profiles

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

Constant Velocity Ratio

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

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 shafts. Sometimes,…
