Due to interference, the tip of one of the gears of the pair will tend to dig into portions of the flank of the tooth of the other member of the pair.

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 the 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 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 the tooth from 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 the center distance between the meshing gears slightly eliminates 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).

Interference in gears
Interference in gears refers to a condition where the tip of a tooth of a mating gear digs into the portion between the base and root circles. This can lead to significant issues in the operation of gears and can result in damage to the gear teeth if not addressed properly.
Causes of interference
There are several factors that can cause interference in gears:
1. Inaccurate gear design: If the gear design is not precise and the teeth are not properly shaped, interference can occur. This can happen when the gear profile is not correctly defined or if there are errors in the calculation of the gear dimensions.
2. Incorrect gear spacing: The spacing between the gears is crucial to ensure smooth operation. If the gears are not properly spaced, it can lead to interference when the teeth of one gear come into contact with the wrong portion of the mating gear.
3. Improper assembly: If the gears are not assembled correctly, it can result in misalignment or uneven spacing, leading to interference between the gear teeth.
Consequences of interference
Interference in gears can have several negative consequences:
1. Noise and vibration: When interference occurs, the gears do not mesh smoothly, leading to noise and vibration during operation. This can result in increased wear and tear on the gears and other components of the system.
2. Reduced efficiency: Interference can cause increased friction and resistance, leading to a decrease in the overall efficiency of the gear system. This can result in energy losses and reduced performance.
3. Damage to gear teeth: If interference is not addressed, it can lead to damage to the gear teeth. The repeated contact between the teeth can cause wear, chipping, or even breakage of the gear teeth, resulting in the need for gear replacement or repair.
Preventing interference
To prevent interference in gears, it is important to ensure accurate gear design and proper assembly. This can be achieved by:
1. Using precise gear design: The gear profile and dimensions should be accurately calculated to avoid interference. This includes considering factors such as pressure angle, module, and addendum.
2. Ensuring proper gear spacing: The gears should be properly spaced to allow for smooth and efficient meshing. This can be achieved by following the recommended gear specifications and guidelines.
3. Performing regular maintenance: Regular inspection and maintenance of the gear system can help identify and address any potential interference issues before they cause significant damage. This includes checking for signs of wear, misalignment, or uneven spacing.
In conclusion, interference in gears occurs when the tip of a tooth of a mating gear digs into the portion between the base and root circles. It can have negative consequences such as noise, vibration, reduced efficiency, and damage to gear teeth. To prevent interference, accurate gear design, proper gear spacing, and regular maintenance are essential.
