Question

If the pressure angle increases, the minimum number of teeth on a pinion to avoid interference increases true false

Answer 1

False

Step-by-step explanation:

The relation between the pressure angle and the number of teeth on a pinion is given by

`T_n = \frac{2 A_w}{G[\sqrt{1+(1)/(G)((1)/(G) +2 }) sin^2\alpha -1]}`

Here

`T_n =` minimum number of teeth on a pinion to avoid interference

`A_w =` Multiplication factor for standard addendum for the wheel

G represents the gear ratio. It is also known as the velocity ratio

`sin \alpha =` Pressure angle or angle of obliquity

As we can see from this relation, that the pressure angle is inversely proportional to the number of teeth on a pinion. Thus, if the pressure angle is increased the number of teeth must decrease according to the relation represented above.

Hence, the given statement is false.
