Sinopsis

Excerpt from Shafting, Keys and Keyways

Assume, for example, that it is re quired to find the diameter of a shaft for transmitting 40 horsepower at a speed of 250 revolutions per minute. The shaft is not subjected to any bending action except its own weight. Consult ing the table to the left on page 4 and locating 40 in the body of the table, in the column under 250 revolutions per minute, we find in the extreme left-hand column that the diameter of the re quired shaft should be two inches. The table also gives the maximum permis sible distance between the shaft bear ings, which in this case is slightly more than 14 feet.

When the exact horsepower given can not be found in the table, it is advisable to take the nearest larger value listed in the table, and find the diameter of shaft required to transmit this horse power.
