Solve the following problem of book design machine elements
Solve the following problem of book design machine elements. Cosidere the following objectives.
a) Propose reasonable dimensions of the shaft to support different types of power transmitting elements and its location on the arrow.
b) Calculate the forces exerted by the different elements of machines that are installed on the shaft.
C) Determine the distribution of torque shaft in question.
D) Determine the support reactions, diagram shear and bending moments in two planes for the axes.
e) Consider the stress concentration factors.
f) Specify appropriate design efforts.
g) Apply the procedure axis design recommended by ANSI B 106.IM-1985 (DESIGN OF TRANSMISSION SHAFTING)
h) Specify reasonable final dimensions of the axes that meet the strength requirements and installation considerations, and are compatible with the elements mounted on them machines.
i) Select the wedges on the elements that are necessary.
j) Select appropriate bearings.
k) Consider the influence of the stiffness of the axle dynamic operation
URGENT SOMEBODY KNOWS ABOUT THIS?
Solution
(a) Torque delivered = Power / angular velocity
= 30 * 745.7 / pi * 480 / 30 = 445.057 Nm of torque
Torque delivered = Ft * r
445.057 = Ft * (5 * 0.0254)
(b) Ft = 3.504 kN (tangential Force on pinion)
(c) Fn = Ft / cos(20) = 3.73 kN (Normal force on pinion)
(d) Fr = Ft * tan(20) = 1.275 kN (Radial force on pinion)
