How Torque and Shaft Size are Connected to Each Other?

If you work with motor driven devices such as fans, pumps, and elevators, finding everything about the size of a shaft and the torque is helpful. The manufacturers consider numerous safety factors to create a quality machine, but among all of this creating a shaft, which is easy to modify in future is the major objective. Hence, finding the relationship between shaft size and torque will lead you to the accurate shaft rotating torque measurements.

So what's the relationship? Let's check it out!    

ü  Bigger Size is Better

Traditionally, a shaft has a bigger size than the equipment itself. Engineers of old times had no chance for the errors that's why using the shaft of bigger size was the only choice to make any electric device efficient. This has become a reason why many industries are still using shafts of bigger size. It provides better torque and makes any device the best device. So, the better shaft rotating torque is achievable with the bigger shaft only.          

  

ü  Shaft Design

The first thing to clear about the shaft size is that it's all about the torque, not the horsepower. But any change in horsepower can affect the torque too. Both increased and decreased horsepower would require more torque. Two approaches are there to determine the size of a shaft for a particular machine. First - shaft large enough and second- calculate minimum diameter to calculate torsion twisting. These methods serve the different purposes and can be built as per the requirement of the machine.         

Wrapping Up

Numerous safety factors and older designs were used to create machinery by the engineers in the past years. But, some machines are overdesigned currently. This is one of the reasons why old designs are still considered to be the best and a few modifications have resulted in many quality devices. The torque and shaft as we already know play an important role inside the body of any device. Therefore, maintaining the shaft rotating torque is the only way to keep your machines running.

Now that you know how torque and the size of the shaft are connected to each other, it's time to buy the quality tools that will help you to maintain both.
