Material Properties of Crank (45 CrNi)
Calculations for Sleeve.• Formula to find the thickness of the sleeve due to heating:
Rf = R1(1+α*(T2-T1))
• R1 = Inner Radius of Sleeve. (130 mm)
• α = Thermal Expansion Coefficient of given material. (13.3E-06)
• T1 = Atmospheric Temperature. (25°C)
• T2 = Giving Temperature. (Variable Values)
• Rf = Final Radius of Sleeve after heating.
• Rf-R1 = Change in Radius
