Transfer of torque - wheel to wheel contact

In summary, the conversation discusses the calculation of torque in a system with various size wheels and the possibility of slip between them. A motor with 100Nm torque and 40000 rpm has a 7mm shaft in contact with a 20mm wheel, which then transfers power to a 15mm wheel. The individual is seeking help in determining the torque of the 15mm wheel and wonders if slip can be accounted for in the calculation. Other participants suggest treating the wheels like gears or pulleys in the calculation.

Hi all,

I am trying to calculate the the torque of a system which uses various size wheels to transfer power.

Explained:

A motor, of 100Nm torque, 40000 rpm, has a shaft of 7mm diameter in contact with a wheel 20mm in diameter. This wheel is in contact with a 15mm wheel.

I need to work out the torque of the 15mm wheel.

Any help would be much appreciated.

Assuming no slip between the wheels you treat them like gear/pulleys.

Do you know how to work out the change in torque on pulleys or gears?

Thanks!

That's the route I have been traveling down but wasnt sure if that was correct.

Is it possible to include slip?
 

Related to Transfer of torque - wheel to wheel contact

1. How does torque transfer occur between wheels in contact?

Wheel to wheel contact allows for the transfer of torque through the friction force between the two surfaces. As one wheel rotates, it exerts a force on the other wheel, causing it to rotate and transfer torque.

2. What factors affect the transfer of torque between wheels?

The amount of torque transferred between wheels is affected by the coefficient of friction, the size and shape of the wheels, and the force applied to the wheels.

3. Can torque be transferred between non-parallel wheels?

Yes, torque can still be transferred between non-parallel wheels as long as there is some contact between the two surfaces and a force is applied.

4. How does the transfer of torque affect the speed and direction of the wheels?

The transfer of torque between wheels can cause changes in both the speed and direction of the wheels. If the wheels are connected, the torque will cause them to rotate at the same speed and in the same direction. If the wheels are not connected, the torque can cause one wheel to rotate faster or in the opposite direction.

5. What are some real-world applications of the transfer of torque between wheels?

The transfer of torque between wheels is used in many everyday devices, such as cars, bicycles, and conveyor belts. It is also essential in more complex machinery, such as engines, gears, and transmissions, to transfer power and control speed and direction.
