1. This is due to the stress concentration at the corners of the key way and reduction in the cross-sectional area of the shaft. It, other words the torsional strength of the shaft is reduced.
2. In case the key way is too long and the key is of sliding type, then the angle of twist increased.
So it is actually assumed that the strength of the keyed shaft is 75% of the solid shaft.

How do you fit a key to a shaft and pulley?
Make sure the key is the correct size for the keyway on both the shaft and pulley. Insert the key into the keyway on the shaft. Slide the pulley onto the shaft, ensuring that the key fits snugly into both the keyway on the shaft and the pulley.
What is a keyed shaft?
A keyed shaft or Keyway is method, based on a machined keyway in shaft, to attach something to the shaft and associated bore. A fitted key is inserted into a slot that is machined into the shaft. Although a machined keyway does result in a weaker shaft, it has it's applications. As in a lawn mower engine shaft. Theoretically the key will give way and save the shaft if you hit something with the blade. The negatives of a keyed shaft are that it can be deformed over time and result is a loose drive.
What are the process of machining a keyway on a shaft by using shaping machine?
Machining a keyway on a shaft using a shaping machine involves several steps. First, the shaft is securely clamped in the machine's vice to prevent movement. The shaping tool, typically a single-point cutter, is then adjusted to the desired depth and width of the keyway. As the machine operates, the cutter moves back and forth across the shaft, removing material to create the keyway profile. Finally, the machined keyway is inspected for accuracy and finish.

How do you put on new keyway on riding mower?
To put a new keyway on a riding mower, first, ensure the mower is turned off and the spark plug is disconnected for safety. Remove the drive pulley or the part that houses the old keyway, and clean the area thoroughly. Insert the new keyway into the slot on the shaft, align it properly, and reassemble the components, making sure everything is secured. Finally, reconnect the spark plug and test the mower to ensure it operates smoothly.
What is the rule of thumb for sizing a key to a shaft?
A common rule of thumb for sizing a key to a shaft is that the key width should be approximately 1/4 of the shaft diameter, while the key height should be about 1/2 of the key width. For example, if the shaft diameter is 1 inch, the key width would be around 0.25 inches, making the key height approximately 0.125 inches. This sizing ensures sufficient strength and grip without compromising the integrity of the shaft or the keyway. Adjustments may be necessary based on specific application requirements and loading conditions.
