So I am specing out a motor that will be connected to a flywheel with a belt. Is the following formula correct?
TFlywheel = (Rout / Rin ) x (Tin)
TFlywheel = (Rout / Rin ) x (Tin)
wakadarc said:Im trying to calculate the torque needed for the flywheel. Attached is a picture of the flywheel (large circle) and the eccentric shaft (medium circle). The small circle is just the projectory of the eccentric shaft rotating around the center of the flywheel. If the load (platform and box on top) is 150kg, what torque would I need? Worst case would be the dead point once the cam reaches the bottom.
wakadarc said:Well there will be a downward force on the platform (gravity). Same with the box. The cam itself will project a force onto the center line of the eccentric shaft regardless of position it is in on the circular path it takes.
Have you done any math to prove this? Recheck it, the mass of the box should have canceled out...Omega will ultimately depend on the box being to able to lift off the platform 15mm...so omega will definitely vary from box to box.
wakadarc said:Wouldn't only the normal force of the shaft cancel out the mg force of the cam/box/platform load when it reaches the bottom of the circular path it takes? See attached. Thanks again
Put two items of different weight in you palm and lift your hand up and down like your platform. Increase the speed until they rise off your palm.wakadarc said:Omega will ultimately depend on the box being to able to lift off the platform 15mm...so omega will definitely vary from box to box.
Torque transfer refers to the transfer of rotational force, or torque, from one object to another. This can happen through various mechanisms, such as gears, pulleys, or direct contact between two rotating objects.
The formula for torque is T = F x r, where T represents torque, F is the applied force, and r is the distance from the point of rotation to the point where the force is applied. Torque is typically measured in units of newton-meters (Nm) or foot-pounds (ft-lb).
The transfer of torque can cause an object to rotate, change direction, or maintain its current rotation. The amount of torque transferred also determines the speed and efficiency of the object's movement.
The main factors that influence torque transfer include the magnitude and direction of the applied force, the distance between the point of rotation and the point of force application, and the properties of the objects involved, such as their mass and surface friction.
Torque transfer plays a crucial role in many everyday activities and technologies, such as driving a car, riding a bike, and using power tools. It is also essential in more advanced applications, such as robotics, machinery, and industrial processes.
