Thanks tygerdawg , mfb & Jobrag..I got fair idea to proceed further.
The formula for torque:
1. Torque to accelerate= MMI x Acceleration.
2. Torque for frication= T=μ*m*g*R
where :
T : the required torque
μ : the friction coefficient
m : the weight of the cylinder
g : Earth gravity
R : radius...
if the mechanism is symmetrical, respective load, torque will be negligible. And consider no bearing friction. Right?
But the formula for torque is
T= mass x g x Radius x coefficient of frication.
I just got confused . please help me.
Thanks mfb & Jobrag, Actually i need to design maintenance cart, where i need to support 1200 kg of assembly. Need to rotate 180 degree for first set of maintenance and then rotate again another 180 degree to complete the remaining work.
Planning to use spur gear mechanism and hand wheel to...
I want to calculate torque to rotate 1200 kg of mass which is attached in 1.5" dia shaft. Shaft is supported by 2 bearings at its end. Neglect bearing frication. Please help.
