| EXTRACT FROM: 8484. R.{Sir Henry Royce} FROM DA.{Bernard Day - Chassis Design} DAL/M.6.12.32. WORK IN PROGRESS - 6.12.32. SLIDING JOINT ON PROPELLER SHAFT. We have looked into the question of a sliding joint with reduced friction. R.{Sir Henry Royce} suggested rollers or balls, and this does not seem to work out badly. Another scheme - though we have not looked into it far enough yet - is to increase the diameter and number of serrations, so as to reduce the pressure per sq.in., and so perhaps save destroying the oil film. The larger serrations do of course also automatically reduce the end loads. DA.{Bernard Day - Chassis Design} | ||
