Now diameter of the gear shaft is determined by using following relation. Te = ----------- x x dg3

DESIGN OF SHAFT FOR SPUR GEAR Wt
Normal load Wn = ----------- cosØ
Weight of the gear WG = 0.00118*T*b*m*m
Resultant load wR = wn2 + wg

If the gear is overhung on the shaft, then the bending moment on the shaft due to resultant load. M = wR x X

ENERGY STORED IN FLY WHEEL Kinetic energy of fly wheel, E = ½ I 2
Since I = m k2 , E = ½ I k2 2
As speed of flywheel changes from <ox to a>2 the maximum fluctuation of energy. ΔE = maximum KE - minimum KE = I 2 Cs
= m k2 2 Cs
= 2ECS
Where I = moment of inertia of fly wheel about the axis M = mass of fly wheel in Kg K = radius of gyration of fly wheel in meters = mean angular speed in rad/sec. Cs = co-efficient of fluctuation of speed

FLYWHEEL MATERIAL
COEFFICIENT OF FLUCTUATION OF SPEED Cs = 2(N1N2) / (N1+N2) In terms of speed
