The reverse shaft is made of 5% case hardened nickel, case hardened on both bearing surfaces, and therefore the trouble is not due to a soft shaft having been used. In regard to the forward bearing, I do not think that the rib running along the bottom, parallel with the axis of the shaft is a good scheme for a fairly heavily loaded bearing. Another supporting web at the front end at right angles to the shaft and embracing the bearing fairly well would in my opinion give better results. BY.{R.W. Bailey - Chief Engineer} | ||
