Unformatted text preview: 3.80 Three shaﬂs and four gears are used to form a gear train which will transmit power ﬁom the motor at A to a machine tool at F. (Bearing for the shafts are omitted in the sketch.) The diameter of each shaﬁ is as follows: d”, = 16 mm, dCD = 20 mm, dEF= 28 mm. Knowing that the frequency of the motor is 24 Hz and that the allowable shearing stress for each shaﬁ is 75 MPa, determine the maximum power that can be transmitted.
