Question

interference occurring in a involute teeth with pinion having smaller number of teeth can be solved by​

Answer 1

Answer:

the minimum number of teeth on the pinion to operate without interference in standard

full-height involute teeth gear mechanism with

20degree pressure angle is 18

Answer 2

System of gear teeth                       Minimum number of teeth on the pinion

14 1 2 degree full depth involute        32

20 degree full depth involute         18

20 degree Stub involute                 14

Explanation:

• 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.
