Question

Twenty degree full depth involute profiled 19-teeth pinion and 37-teeth gear are in mesh. If the module is 5 mm, the center distance between the gear pair will be

• A. 140 mm
• B. 150 mm
• C. 280 mm
• D. 300 mm

Answer 1

The correct option is A 140 mm

Given data:

$T_p=10,T_a=37\text{and}m=5$

$m=D/T$

$D_p=95\text{mm}$

$D_G=185\text{mm}$

$\text{Centre distance}=\frac{95+185}{2}=140\text{mm}$
