Hanbury - Head Complaints} 24.2.26. -------------------- SHOCK ABSORBER LINKS. -------------------- Referring to your memo on the above subject, I am of the opinion that the main reason for the link bursting is expanding of the pin into the link. The process of turning over the end of the pin on to the links necessarily tends to increase the diameter of the bore at the outer edge during the sweating operation. The result of this is that the eye tends to split in the direction parallel with the flow lines introduced in the material by the rolling operation. There would be an advantage in making this link in nickel steel, but even if made in nickel steel I consider that the dimensions of the eye should be increased to an extent to permit of increasing the section of the material by another 25% on diameter. This means roughly that I would like to add .100 on diameter. BY.{R.W. Bailey - Chief Engineer} | ||
