A pair of spur pinion and gear made of cast steel (Sut = 110 MPa) and cast iron (Sut = 55 MPa) respectively. The pinion transmits 3274 N at 1250 rpm. The gear ratio is 3 : 1 and the teeth are full involute. Form factor y = .Width is 12 times module. The no. of teeth on pinion is 16, the module is
  • a)
    7 mm
  • b)
    6 mm
  • c)
    1.22 mm
  • d)
    3.42 mm
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A pair of spur pinion and gear made of cast steel (Sut = 110 MPa) and...
Tp = 16, TG = 48,w = 12 m
YG = π X 0.135
SPYP = 110 X π X 0.097 = π X 10.67
SGYG = 55 x π x 0.135 = 7.425 x π
∴ Gear is weak
Ft = SWmY CV
3274 = 7.425 x π x 12 m x m x 1
m = 3.42 mm
