normally a shaft carrying such heavy loads is subject to heavy initial torque....and u have two loads on either side, it doesnt matter if it is in grmas, but if it is in kgs, the bodies tend to run outside the path of the wheel due to centrfugal force, so the shaft should be strong enough to minimise that.....and torque is inversely proportional to rated rpm.....mount the shaft with the wheel ...
How to calculate torque of motor: Torque is nothing but a momentary force developed at the time of force is applied to the motor. The unit of torque is N.m (Newton-meter). In other words, Torque T (N.m) is equal to the ratio between the electrical power P (W) in watts to the acceleration.
The two V-belt pulleys form an integral unit and rotate about the fixed axis at O. At a certain instant, point A on the belt of the smaller pulley has a velocity v A =1.5 m/s, and point B on the belt of the larger pulley has an acceleration a B = 45 m/s2 as shown. For this instant determine the magnitude of the acceleration a …

· From this I calculate the torque to be 6.2 kN and using an efficiency factor of 0.85 the power needed would be 3.0 kW. The driving force is provided by forcing the smooth surface of a grooved transmission belt, driven by the motor, against the surface of the chain block over a distance of 1.2mtr.
ε = belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note: For long-distance conveyors, dynamic start-up calculations. may be required, because not all elements are set in motion simultaneously, due to the elastic properties of the conveyor belt.

Consider a pulley wheel with a belt passing around it as shown. In order for the belt to produce a torque on the wheel (whether or not it is rotating), there must be tension in both ends. If this was not so, the belt would not be pressed against the wheel and it would slip on the wheel. The belt depends upon friction between it and the wheel in
Assume a helicopter blade is a thin rod, with a mass of 150.0 kg and a length of 8.00 m. To achieve an angular acceleration of 18.00 radians/s 2, what torque is required? Answer: The torque can be found using the torque formula, and the moment of inertia of a thin rod. The torque is: τ = Iα. τ = 14 400 N∙m. The torque required is 14 400 N∙m.
The change in torque is just the reciprocal of the change in RPM. That is, if you reduce the RPM to one-half of what it was, the torque will be doubled. On a Challenger, the belt drive system (tall redrive) reduces the RPM from engine to prop by a factor of 2.6 : 1. This means that the torque delivered to the prop is . 2.6 x 40 ft-lbs = 104 ft-lbs.

· The belt-driven spindle can deliver more power below 10,000 rpm than the high speed spindle. (See diagram at left.) A more complete explanation for the performance difference is that the motor for the belt-driven spindle develops more torque at low speeds. The difference is obvious when the torque curves are compared. (See diagram at right.)
