8- Problem:

A flanged coupling connects two transmission devices with pins of diameter 12 mm made of EN3 steel, at pitch circle diameter of 150 mm, If a torque of 2,600 Nm is applied with a required safety factor of 5, calculate the maximum number of studs pins required.

 

Given: T = 2600 Nm Material: EN3 SF = 5 D = 150 mm d = 12 mm    Required:  n (number of pins)
Solution: From Chart 9 for steel EN3
