Adding Power of Two Chain Drives Without Slipping

In summary, the author suggests that if you want to add power to two chain drives that have different RPMs, you can use gearing or a CVT. However, you will need to think through the design carefully to make sure the system is stable.

is there any way to add power of two independent chain drives having different rpm , such that slipping doesn't occur and driven shaft move with the added resultant power

Welcome to the PF.

Is the ratio of the 2 speeds constant? If so, you can use gearing. If not, you could consider a CVT (continuously variable transmission) as part of the coupling...

A differential in reverse. I believe there is a word for that but it escapes me. Combiner perhaps?

How cool. I haven't seen that before...

You need to think this through carefully, otherwise you may end up with one motor driving the other motor backwards instead of driving the load. If this is a problem you would have to add something that works the same as a limited slip differential.

For many types of motor, the power output depends on the RPM, so you will need to make sure the drive system is stable, in the sense that one motor can't speed up and produce more power, and force the other motor to slow down and produce less power.

John Deere does it in their IVT tractors. Nothing new. That is not to say they aren't loaded with sensors to keep tabs on what is going on. The unit has a hydrostatic drive on one side of the combiner and straight in mechanical on the other side. You set a target speed and the computer sets the engine RPM and the IVT to maintain this speed at maximum economy.
 

1. How do you calculate the power of two chain drives without slipping?

To calculate the power of two chain drives without slipping, you will need to know the speed of the driving sprocket, the number of teeth on the driving sprocket, and the number of teeth on the driven sprocket. You can use the formula Power = (Speed x Torque) / 5252 to calculate the power in horsepower (HP).

2. What is the purpose of adding power of two chain drives without slipping?

The purpose of adding power of two chain drives without slipping is to increase the power transmission efficiency, reduce wear and tear on the chains, and decrease the chances of slipping or breaking of the chains. This allows for smoother and more reliable operation of machinery.

3. How do you prevent slipping in power of two chain drives?

To prevent slipping in power of two chain drives, proper tension must be maintained on the chains. This can be achieved by using a tensioner or by adjusting the center distance between the two sprockets. It is also important to regularly lubricate the chains and ensure that they are in good condition.

4. What factors can cause slipping in power of two chain drives?

Slipping in power of two chain drives can be caused by various factors such as inadequate tension on the chains, worn or damaged sprockets, insufficient lubrication, misalignment of the sprockets, or excessive load on the chains.

5. Are there any disadvantages to adding power of two chain drives without slipping?

One potential disadvantage of adding power of two chain drives without slipping is that it can increase the complexity and cost of the system. Additionally, if the tension is not properly maintained, it can lead to premature wear and failure of the chains. However, the benefits of increased power transmission efficiency and reduced slipping and wear generally outweigh any potential drawbacks.
