Verified Answer
The Interference or undercutting in involute gears can be avoided by:-...
Methods of elimination of Gear tooth Interference:
- Use of a larger pressure angle (having a larger pressure angle results in a smaller base circle. As a result, more of the tooth profiles become involute)
- Under-cutting of tooth (A portion of teeth below the base circle is cut off. When teeth are produced by this process, the tip of one tooth of a gear will not contact the non-involute portion of the tooth of other gear)
- Tooth stubbing (In this process a portion of the tip of the teeth is removed, thus preventing that portion of the tip of tooth in contacting the non-involute portion of the other meshing tooth).
- Increasing the number of teeth on the gear can also eliminate the chances of interference.
- Increasing slightly the center distance between the meshing gears would also eliminate interference.
- Tooth profile modification or profile shifting (Using profile shifted gears (gears with non-standard profile) can also be an option to eliminate interference. In profile shifted meshing gears, the addendum on the pinion is shorter compared with standard gears).

Avoiding Interference in Involute Gears
There are several ways to avoid interference or undercutting in involute gears:
1. Varying the Centre Distance by Changing Pressure Angle: One way to avoid interference is to vary the centre distance between the gears by changing the pressure angle. This can be done by using gears with different pressure angles, or by using gears with a variable pressure angle.
2. Using Modified Involute or Composite System: Another way to avoid interference is to use modified involute or composite system gears. These gears have a modified tooth profile that is designed to reduce the likelihood of interference. The modified profile can be achieved by changing the shape of the teeth or by using a combination of different tooth profiles.
3. Increasing the Addendum of Small Wheel and Reducing it for the Larger Wheel: Increasing the addendum of the smaller wheel and reducing it for the larger wheel can also help to avoid interference. This can be done by increasing the height of the teeth on the smaller gear and decreasing the height of the teeth on the larger gear.
4. Using All Options: The most effective way to avoid interference is to use a combination of these methods. By varying the centre distance, using modified tooth profiles, and adjusting the addendum of the gears, it is possible to design gears that will not interfere with each other.
In conclusion, avoiding interference in involute gears is important for ensuring the smooth operation of the gears. By using the methods outlined above, it is possible to design gears that will not interfere with each other, and that will provide reliable and efficient performance.
